Small-to-Medium Business Owners & Leaders, How Much Debt Is Too Much? Finding the Optimal Debt Level Before Borrowing Becomes a Business Risk.

Debt is neither inherently good nor inherently bad.

Used intelligently, debt can accelerate growth, fund productive assets, smooth working capital, finance acquisitions, increase returns on shareholders’ capital and allow business owners to pursue opportunities without surrendering equity.

Used badly, debt can quietly turn a successful business into a fragile one.

The difference is rarely the existence of debt itself.

The difference is whether the business has the earnings, cash flow, resilience and financial discipline to carry that debt when circumstances are less favourable than expected.

That distinction matters particularly for small-to-medium businesses.

Large corporations can often access multiple sources of capital, refinance in sophisticated debt markets, sell assets, issue equity and spread risk across numerous operations. SME owners generally have fewer options. Their business debt may also be supported by personal guarantees, mortgages over property or other personal assets.

The Reserve Bank of Australia has previously noted that indebted smaller businesses can be particularly exposed to interest-rate increases because much small-business lending is variable-rate and a significant proportion is secured against residential property.

The question for an SME owner should therefore not simply be:

“How much will the bank lend me?”

It should be:

“How much debt can this business prudently carry without compromising its resilience, strategic freedom or long-term value?”

Those are very different questions.

And in my view, confusing borrowing capacity with prudent debt capacity is one of the most dangerous financial mistakes a business owner can make.

Debt Is a Tool, Not a Strategy (Business Growth Perth)

One of the first principles SME owners should understand is that debt is a financing mechanism, not a business strategy.

Borrowing money does not fix an inadequate business model.

It does not make an unprofitable product profitable.

It does not correct weak pricing.

It does not solve poor management.

It does not create sustainable competitive advantage.

And it certainly does not turn uncontrolled growth into good growth.

Debt simply provides capital.

What happens next depends upon what management does with that capital.

Consider two businesses that each borrow $1 million.

Business A uses the money to purchase productive equipment that increases capacity, reduces unit costs, improves margins and generates $300,000 of additional sustainable annual operating cash flow.

Business B borrows the same $1 million to cover recurring operating losses, overdue tax obligations and working-capital shortages caused by poor debtor collection.

Both businesses have borrowed $1 million.

Economically, however, the transactions could hardly be more different.

Business A has potentially used leverage to create additional enterprise value.

Business B may simply have postponed confronting an underlying business problem.

That is why the first question before borrowing should not be:

Can we obtain the money?

It should be:

What will this money produce?

The distinction becomes particularly important when funding growth. As discussed in my article on when ambition for business growth becomes a business risk, rapid expansion can consume cash long before the corresponding revenue is collected.

Debt can bridge that gap.

But it can also magnify it.

Why the Maximum a Bank Will Lend Is Not Your Optimal Debt Level (Business Advisor Perth)

A lender and a business owner are asking related, but fundamentally different questions.

The lender is primarily asking:

“What is the probability that we will get our money back, together with interest?”

The owner should be asking:

“What financial structure gives my business the best combination of growth, return, resilience, flexibility and acceptable risk?”

A lender may be comfortable advancing money because it has:

• security over business assets,
• a mortgage over property,
• personal guarantees,
• strong historical financial statements,
• covenant protections, or
• sufficient collateral to reduce its potential loss.

None of those necessarily means that taking the maximum available facility is the right decision for the business.

Australian Government guidance on applying for a business loan appropriately recommends that owners understand their income, expenses, debts and cash flow, determine the maximum repayment they can afford, and consider collateral and guarantees before borrowing.

This leads to an important principle:

Bankability is not the same thing as affordability, and affordability is not the same thing as optimal capital structure.

A business might technically be able to service $3 million of debt.

That does not automatically mean it should carry $3 million.

Perhaps $2 million leaves enough headroom to survive a 20% reduction in EBITDA.

Perhaps $1.5 million preserves capacity for a future acquisition.

Perhaps $2.5 million works provided part of the interest-rate exposure is managed.

Perhaps the business should use a mixture of retained earnings, debt and new equity rather than debt alone.

Determining the appropriate answer requires more than looking at the loan approval.

It requires understanding the economics of the business.

What Is an Optimal Debt Level? (Business Improvement Perth)

There is no universal debt-to-equity ratio that represents the “correct” debt level for every SME.

An optimal level of debt is better understood as:

The amount and structure of debt that allows a business to pursue worthwhile opportunities and improve shareholder returns while retaining sufficient cash-flow capacity, liquidity, covenant headroom and financial resilience to withstand reasonably foreseeable adverse conditions.

That definition contains several important ideas.

Debt must have a commercial purpose

Why are you borrowing?

To purchase equipment?

Fund inventory?

Finance an acquisition?

Expand into another market?

Buy property?

Bridge a temporary working-capital cycle?

Or simply because the business keeps running out of cash?

The last reason should immediately trigger deeper investigation.

Persistent cash shortages may be symptoms of poor margins, inadequate pricing, excessive overheads, slow debtor collection, excessive inventory, uncontrolled drawings, tax arrears or declining business performance.

More debt can temporarily disguise these problems rather than solve them.

My Business Performance Improvement Pyramid examines the broader operational and financial levers available to improve performance. Borrowing should never become a substitute for addressing those fundamentals.

Debt must be serviceable

A business must generate enough cash to meet:

• interest,
• principal repayments,
• tax,
• working-capital requirements,
• capital expenditure,
• dividends or owner drawings, and
• an adequate liquidity reserve.

A business that can service debt only when everything goes according to plan is probably carrying too much debt.

Debt must leave headroom

This is one of the most overlooked concepts in SME borrowing.

A forecast showing that the business can “just” make its repayments is not reassuring.

It is a warning.

There should be meaningful financial headroom between expected cash generation and mandatory financial commitments.

That buffer is what protects the business when:

• a major customer pays late,
• revenue falls,
• margins contract,
• wages increase,
• an important contract is lost,
• equipment fails,
• interest rates rise,
• inventory builds,
• a project runs over budget, or
• an unexpected opportunity requires capital.

Financial headroom is not idle money. It is strategic resilience.

Productive Debt Versus Destructive Debt (Strategic Planning Perth)

One useful way to think about SME borrowing is to separate productive debt from destructive debt.

Productive debt finances something expected to create sufficient economic value or cash flow to justify the financing cost and additional risk.

Examples may include:

• revenue-producing equipment,
• capacity expansion supported by genuine demand,
• strategically appropriate acquisitions,
• inventory required for profitable growth,
• commercial property where the economics are compelling,
• technology that materially improves productivity,
• expansion into a well-researched market, or
• working capital supporting profitable contracted revenue.

Destructive debt is different.

It often funds:

• recurring operating losses,
• excessive owner drawings,
• overdue tax obligations without fixing the underlying cause,
• speculative expansion,
• uneconomic acquisitions,
• excess inventory,
• poorly controlled projects,
• lifestyle assets disguised as business expenditure, or
• previous debt repayments.

The distinction is not always black and white.

A working-capital facility, for example, can be extremely productive if it finances profitable growth. The same facility becomes dangerous when permanently drawn to its limit because the business is structurally cash-flow negative.

This is why debt must be considered within the organisation’s broader strategic planning process.

Financing strategy should follow business strategy.

Not the other way around.

The Five Factors That Determine How Much Debt Your Business Can Carry (Business Advisor Perth)

Every business has a different debt capacity.

Five factors deserve particular attention.

1. Earnings stability

A company producing predictable recurring earnings can generally tolerate more leverage than one whose profits fluctuate dramatically.

Consider the difference between a business with:

• contracted recurring revenue,
• diversified customers,
• stable margins, and
• predictable demand,

and one dependent upon:

• project work,
• one major customer,
• commodity prices,
• seasonal demand, or
• highly cyclical markets.

The same debt-to-EBITDA ratio could represent acceptable leverage in the first business and dangerous leverage in the second.

2. Cash-flow conversion

EBITDA is important, but lenders are repaid with cash.

A company can report attractive accounting profits while simultaneously experiencing severe cash pressure.

Why?

Because cash may be trapped in:

• receivables,
• inventory,
• work in progress, or
• capital expenditure.

A fast-growing business can therefore become more profitable and less liquid at exactly the same time.

That apparent contradiction catches many SME owners by surprise.

3. Asset backing

A capital-intensive business with valuable, saleable assets may have greater financing options than a service business whose principal assets are people, relationships and intellectual property.

But asset backing should not create false comfort.

The purpose of borrowing is not to give the bank something to sell if the business fails.

The purpose is to finance a business that can comfortably meet its obligations from operating cash flow.

4. Industry cyclicality

Debt capacity must reflect the downside characteristics of the industry.

Construction, property, agriculture, discretionary retail, mining services and other cyclical sectors can experience substantial changes in activity and cash flow.

A debt structure that appears conservative at the top of the cycle can become highly leveraged surprisingly quickly when EBITDA contracts.

5. Management quality and financial discipline

Two businesses with identical financial statements can have very different risk profiles.

A management team with:

• reliable forecasting,
• disciplined budgeting,
• weekly cash-flow visibility,
• strong debtor control,
• meaningful KPIs,
• prudent capital allocation, and
• effective governance

is far better positioned to manage leverage than a business whose owner discovers the cash balance by opening the banking app.

Good financial management therefore increases not merely the ability to obtain debt, but the ability to use debt intelligently.

That is one reason disciplined KPIs, forecasting and management reporting matter so much.

The Ratios Every SME Owner Should Understand

No single financial ratio determines the correct level of debt.

The value comes from considering several measures together and examining their trend over time.

Debt-to-Equity Ratio

At its simplest:

Debt-to-Equity = Total Debt ÷ Shareholders’ Equity

Suppose a company has:

• debt of $2 million, and
• shareholders’ equity of $4 million.

Debt-to-equity is:

$2m ÷ $4m = 0.50, or 50%.

The ratio indicates the relationship between borrowed capital and shareholders’ capital.

But it has limitations.

Book equity may bear little relationship to current enterprise value, particularly where assets have appreciated, intangible value is substantial or historical accounting values are involved.

So it should not be used in isolation.

Debt-to-EBITDA

This ratio asks how large debt is relative to operating earnings:

Debt-to-EBITDA = Debt ÷ EBITDA

If debt is $3 million and EBITDA is $1 million:

Debt-to-EBITDA = 3.0×

Conceptually, the higher the multiple, the greater the leverage.

But again, context matters enormously.

Three times EBITDA in a highly predictable business is not necessarily equivalent to three times EBITDA in a cyclical business whose earnings can fall 40% in a downturn.

And that leads to the ratio many owners overlook.

Interest Coverage

Interest Coverage = EBIT or EBITDA ÷ Interest Expense

Suppose EBITDA is $1 million and annual interest is $200,000.

Coverage is:

5.0×

If EBITDA falls to $600,000 while interest remains $200,000, coverage falls to:

3.0×

If interest simultaneously rises to $250,000:

Coverage falls to 2.4×.

Nothing happened to the original principal balance.

Yet the financial risk of the business changed dramatically.

That is precisely why leverage should be stress-tested rather than assessed only against today’s conditions.

Current Australian borrowing costs reinforce the point. RBA data for June 2026 showed average outstanding lending rates of approximately 7.45% for small businesses, compared with 6.17% for medium businesses and 5.70% for large businesses.

The RBA has also reported that business lending rates rose in 2026 broadly in line with movements in short-term interest rates.

For an SME carrying several million dollars of variable-rate debt, movements in borrowing costs can therefore materially change free cash flow.

Why Cash Flow Matters More Than Accounting Profit (Business Improvement Perth)

An SME can be profitable and still become insolvent.

That statement is fundamental to understanding debt.

Imagine a business growing revenue from $10 million to $15 million.

Margins remain healthy.

The income statement looks excellent.

But customers take 60 days to pay, inventory must be purchased before sales occur, additional employees are required and suppliers demand payment within 30 days.

Growth consumes working capital.

The company may therefore require significantly more cash precisely because it is growing successfully.

This is one reason my article on business funding options emphasises matching the source of finance to the underlying requirement.

The critical question is not simply:

“Will this investment increase profit?”

It is:

“When will the cash arrive, and what happens to liquidity before it does?”

That distinction becomes particularly important when debt principal repayments commence immediately but the investment being financed takes 12, 18 or 24 months to produce its expected cash return.

A mismatch between the timing of cash inflows and financing obligations can place an otherwise sound business under unnecessary pressure.

Debt should therefore be structured around cash-flow reality, not merely accounting profitability.

The Debt Service Coverage Ratio, Can the Business Actually Carry the Debt? (Business Improvement Perth)

Debt-to-EBITDA tells you something about leverage. Interest coverage tells you something about the burden of interest.

But neither necessarily answers the most practical question facing an SME owner:

After generating cash from operations, can the business comfortably meet all of its scheduled debt repayments, including principal and interest?

That is where the Debt Service Coverage Ratio, DSCR, becomes particularly useful.

A simplified version is:

DSCR = Cash Available for Debt Service ÷ Total Annual Debt Service

Suppose a business generates $1.2 million of cash available for debt service and must pay:

• $250,000 in interest, and
• $350,000 in scheduled principal repayments.

Total debt service is $600,000.

DSCR is therefore:

$1,200,000 ÷ $600,000 = 2.0×

In simple terms, the business generates twice the cash required to meet its scheduled debt commitments.

Now imagine cash available for debt service falls to $720,000.

The ratio becomes:

$720,000 ÷ $600,000 = 1.2×

The business can still technically meet its debt commitments, but the margin for error has become dramatically smaller.

At 1.0×, virtually all available cash is required for debt service.

Below 1.0×, the business is not generating sufficient cash from the measured operations to meet those commitments without using cash reserves, selling assets, drawing additional facilities, obtaining shareholder funding or taking some other action.

The precise DSCR definition used by lenders can vary, particularly regarding tax, capital expenditure, leases, distributions and other adjustments. SME owners should therefore understand exactly how their lender calculates it rather than assuming every DSCR covenant means the same thing.

The principle, however, is straightforward:

The question is not whether you can make next month’s repayment. The question is how comfortably you can continue making repayments if business conditions deteriorate.

Government guidance similarly emphasises understanding income, expenses, existing debts and cash flow, and determining the maximum repayment a business can afford before borrowing.

Never Approve Significant Debt Without Stress-Testing It (Strategic Planning Perth)

One of the biggest weaknesses in SME financial planning is the reliance on a single forecast.

Management prepares a budget.

Revenue grows 10%.

Margins remain broadly stable.

Costs increase approximately as expected.

Customers pay on time.

Interest rates behave.

The proposed investment performs according to plan.

Debt repayments are comfortably covered.

The spreadsheet works.

The loan is approved.

But businesses do not operate inside spreadsheets.

A forecast is an expectation, not a guarantee.

Before accepting significant new debt, management should ask what happens when several assumptions move against the business simultaneously.

This is where sensitivity analysis and scenario analysis become invaluable.

A Practical SME Debt Stress Test

Take the proposed debt structure and model at least three scenarios:

Base Case: Management’s realistic forecast.

Downside Case: Trading conditions deteriorate materially but remain plausible.

Severe but Plausible Case: Several adverse events occur simultaneously.

For example, if the base forecast assumes:

• revenue of $12 million,
• EBITDA margin of 15%,
• EBITDA of $1.8 million,
• debt of $4 million,
• interest rate of 7%,
• annual interest of $280,000,

then do not stop there.

Test what happens if:

• revenue falls 10%,
• gross margin declines two percentage points,
• wages rise 5%,
• debtor days increase from 40 to 55,
• interest rates rise another 2%,
• a major customer is lost,
• inventory increases,
• a planned project is delayed by six months, and
• capital expenditure exceeds budget.

Then test combinations.

That last point is critical.

Businesses rarely experience problems neatly, one at a time.

A slowdown in revenue may coincide with slower debtor collections. Lower volume may reduce purchasing leverage. A customer failure may create a bad debt. The bank may become more cautious precisely when additional liquidity is needed.

The RBA’s March 2026 Financial Stability Review specifically noted that higher interest expenses and input costs were expected to increase cash-flow pressure for some smaller Australian businesses, and that pass-through from higher rates can be faster for small businesses because many use variable-rate borrowing.

Your debt strategy therefore needs to survive the downside case, not merely look attractive in the base case.

Sensitivity Analysis, Find Out What Can Break the Business (Business Improvement Perth)

Sensitivity analysis is not simply an exercise for accountants or financial analysts.

It is one of the most useful strategic tools available to an SME owner.

The objective is to identify the variables to which debt-service capacity is most sensitive.

For example:

This simplified example demonstrates something extremely important.

The amount of debt has not changed.

It remains $4 million in all three scenarios.

Yet leverage deteriorates from approximately 2.2× EBITDA to approximately 4.6× simply because earnings decline.

This is why statements such as:

“We only owe $4 million.”

can be financially meaningless without context.

Four million dollars of debt against $2 million of sustainable EBITDA is one thing.

Four million against $800,000 is something completely different.

Calculate Your Break-Even Point

Owners should also ask:

At what point does the business stop comfortably servicing its debt?

How far can revenue fall?

How much can gross margin contract?

How high can interest rates rise?

How much slower can customers pay?

At what EBITDA level would a banking covenant be breached?

How much cash would remain after debt service?

This transforms debt management from a backward-looking accounting exercise into a forward-looking risk-management discipline.

It is also closely connected with understanding the broader business performance levers that influence revenue, margins, costs, working capital, profitability and ultimately cash flow.

Interest-Rate Risk, A Small Percentage Change Can Mean a Large Dollar Change

Interest rates matter because leverage magnifies small percentage movements into significant cash costs.

Consider an SME carrying $5 million of variable-rate debt.

At 6%, annual interest is approximately:

$300,000

At 7%:

$350,000

At 8%:

$400,000

At 9%:

$450,000

A movement from 6% to 9% adds approximately:

$150,000 per annum

to the interest bill, before considering principal repayments.

That $150,000 has to come from somewhere.

It might mean:

• reduced profit,
• lower distributions,
• deferred capital expenditure,
• reduced recruitment,
• lower marketing expenditure,
• delayed expansion,
• reduced cash reserves, or
• increased pressure on working capital.

This is particularly relevant in the current Australian environment. RBA data for June 2026 showed the average rate on outstanding small-business lending at approximately 7.45%, compared with 6.17% for medium businesses and 5.70% for large businesses.

The RBA’s August 2026 Statement on Monetary Policy also reported that lenders had passed recent cash-rate increases through to business lending rates, while business debt growth remained above its post-GFC average.

This reinforces an important lesson:

Do not assess a long-term borrowing decision solely against today’s interest rate.

Ask what happens at today’s rate plus 1%, plus 2%, and, where appropriate, plus 3%.

Fixed or Variable? Understand the Risk You Are Accepting

There is no universally correct answer to whether SME debt should be fixed or variable.

Variable debt may offer:

• flexibility,
• potentially lower rates at certain points in the cycle,
• easier early repayment in some facilities, and
• benefit if market interest rates decline.

Fixed-rate borrowing may provide:

• greater certainty,
• easier cash-flow forecasting, and
• protection against rising rates during the fixed period.

The appropriate decision depends on the business, facility, loan term, pricing, break costs, cash-flow stability and owner’s appetite for interest-rate risk.

For a sufficiently large exposure, it may also be appropriate to discuss hedging or a mixture of fixed and variable debt with suitably qualified financial and banking advisers.

The strategic question is:

How much interest-rate uncertainty can the business afford to carry?

That is more useful than trying to predict exactly where interest rates will be in two years.

Refinancing Risk, The Debt You Can Afford Today May Not Be Available Tomorrow

Interest-rate risk receives considerable attention.

Refinancing risk often receives too little.

Suppose an SME has a $3 million facility expiring in three years.

Management assumes:

“We will simply refinance it.”

Perhaps.

But what if, at refinancing:

• EBITDA has declined,
• the industry is out of favour,
• the property securing the loan has fallen in value,
• the lender has changed its credit appetite,
• banking covenants have tightened,
• the owner is approaching retirement,
• a major customer has been lost,
• the lender wants the principal reduced, or
• alternative finance is materially more expensive?

Debt maturity should therefore be actively managed.

Do not wait until several weeks before expiry to discover what the bank wants.

For material facilities, management should maintain a forward schedule showing:

• facility limits,
• amount drawn,
• interest rates,
• fixed/variable status,
• security,
• guarantees,
• covenants,
• expiry dates,
• amortisation schedules, and
• refinancing milestones.

This should form part of normal management reporting and, where appropriate, Board oversight.

Strong business governance includes understanding not just current financial performance but significant future financial obligations and risks.

Match the Debt to the Purpose

One of the most important principles of business finance is remarkably simple:

The term and structure of the finance should broadly match the purpose for which the money is being used.

Short-term assets generally justify short-term finance.

Long-lived assets generally require appropriately structured longer-term finance.

Problems arise when those are mismatched.

Working Capital

An overdraft or revolving facility can be appropriate for temporary working-capital fluctuations.

For example:

• inventory is purchased,
• goods are sold,
• customers pay,
• the facility reduces,
• and the cycle repeats.

Australian Government guidance similarly describes an overdraft as potentially useful for bridging short-term cash-flow gaps, while warning against relying on it for capital purchases or long-term financing.

A healthy working-capital facility should therefore generally move.

If an overdraft has been sitting permanently at or near its limit for years, it may no longer be financing a temporary cash-flow cycle.

It may effectively be permanent debt.

That deserves investigation.

Plant and Equipment

Equipment with an economic life of five or seven years may appropriately be financed over a related period, depending on residual value, utilisation, cash generation and lender terms.

Property

Commercial property may justify considerably longer-term finance.

Acquisitions

Acquisition debt should reflect the sustainable cash flow of the combined business and allow for integration risk, not merely the vendor’s historical EBITDA.

Tax Debt

Tax debt requires particular attention.

GST, PAYG withholding and superannuation are not normal sources of working capital.

If an SME is repeatedly using money earmarked for statutory obligations to finance operations, the problem is often deeper than financing structure.

The RBA has specifically observed that financial stress remains higher among some smaller businesses, including businesses that accumulated sizeable debts such as unpaid GST.

Working Capital Can Quietly Consume Enormous Amounts of Debt

Owners often associate borrowing with buying machinery, property or businesses.

But working capital can be equally significant.

Consider a company growing from $10 million to $15 million of revenue.

If debtor days are 60, the additional $5 million of revenue may require roughly:

$822,000 of additional receivables

before considering GST and other factors.

If inventory must also increase by $500,000, the business may suddenly require more than $1.3 million of additional working capital.

That is before allowing for other changes.

The business is growing.

Profit may be increasing.

Yet cash may be disappearing.

This is why a proper cash-flow forecast matters. Australian Government guidance notes that cash-flow forecasting can help businesses anticipate shortages and surpluses and ensure sufficient money is available to cover payments.

A growth strategy without a working-capital strategy is incomplete.

Debt-Funded Growth, When Success Creates Financial Danger (Business Growth Perth)

Growth creates excitement.

More customers.

More employees.

More trucks.

More equipment.

More locations.

More inventory.

More revenue.

But revenue growth and cash generation are not the same thing.

A rapidly expanding SME can run out of cash because each incremental dollar of revenue requires capital before the customer eventually pays.

This produces one of the great paradoxes of business:

A profitable company can grow itself into financial distress.

That is why the risks associated with excessive or poorly controlled growth should be considered before debt is used to accelerate expansion.

Before borrowing to fund growth, ask:

• What additional revenue should the investment produce?
• What gross margin will that revenue generate?
• How quickly will customers pay?
• What additional inventory is required?
• What additional employees and overheads are required?
• When does the investment become cash-flow positive?
• What happens if growth is 50% slower than forecast?
• What happens if margins are lower?
• Can the debt still be serviced?
• What is the exit strategy if the expansion fails?

Debt should accelerate economically sound growth.

It should not be used to manufacture the appearance of growth.

Acquisition Debt, Leverage Can Magnify Both Success and Failure (Business Advisor Perth)

Acquisitions are one of the areas where debt can create enormous value, or destroy it.

Suppose an SME buys another business for $5 million.

The acquisition is partly funded by $3 million of debt.

Management expects:

• $1 million of EBITDA,
• $300,000 of synergies,
• cross-selling opportunities,
• reduced overhead duplication, and
• substantial strategic benefits.

The transaction appears compelling.

But what happens if:

• EBITDA was temporarily inflated before sale,
• a major customer leaves,
• key employees resign,
• synergies take two years rather than six months,
• systems integration costs twice as much as expected,
• working capital was underestimated,
• the seller’s relationship-based revenue does not transfer,
• interest rates increase, or
• management becomes distracted from the existing business?

The purchase price has already been paid.

The debt remains.

The expected earnings may not.

This is why my discussion of business acquisitions for SMEs emphasises disciplined due diligence and realistic assumptions.

Never finance an acquisition based primarily on the best-case synergy model.

Debt capacity should be assessed against sustainable, defensible cash flows.

The Hidden Cost of Personal Guarantees

For many SME owners, the distinction between “business debt” and “personal risk” is much less clear than it appears on the balance sheet.

A lender may require:

• a director’s guarantee,
• a personal guarantee,
• security over property,
• security over business assets, or
• some combination of these.

Government guidance explicitly recommends considering what collateral may be required and who will guarantee a loan before borrowing.

This changes the nature of the decision.

An owner may believe:

“The company is borrowing $2 million.”

The economic reality may be closer to:

“The company is borrowing $2 million, and I am placing a meaningful portion of my family’s accumulated wealth behind the company’s ability to repay it.”

That should change the conversation.

Before providing a significant personal guarantee, owners should understand:

• precisely what is being guaranteed,
• whether the guarantee is limited or unlimited,
• which assets may be exposed,
• whether guarantees are joint and several,
• what happens when ownership changes,
• what happens when a director leaves,
• how and when the guarantee can be released, and
• whether independent legal advice is appropriate.

A guarantee should never be treated as routine paperwork.

Beware of Cross-Collateralisation

Another risk arises when multiple facilities, properties and business assets become interconnected.

A lender may hold security across several entities or assets.

This can make refinancing, selling an asset, changing banks or restructuring ownership significantly more complicated.

For example, an owner may wish to sell a commercial property only to discover that the lender requires part of the proceeds to reduce unrelated business debt.

Or the owner may want to refinance one facility with another bank but find that existing securities cannot easily be released.

This is not necessarily inappropriate.

But it needs to be understood before the structure is established.

Optimising debt is therefore not merely about the interest rate.

It also involves:

security + guarantees + covenants + maturity + repayment structure + flexibility + control.

A loan with a slightly higher interest rate but substantially greater strategic flexibility may, in some circumstances, be economically superior to the cheapest headline facility.

The Warning Signs Your Business May Be Becoming Overleveraged (Business Improvement Perth)

Excessive debt rarely announces itself with a single dramatic event.

The warning signs often accumulate gradually.

Pay particular attention if:

• overdrafts are permanently near their limits,
• tax payments are repeatedly deferred,
• suppliers are being stretched beyond agreed terms,
• management is borrowing to make previous debt repayments,
• debt is rising faster than sustainable EBITDA,
• interest coverage is steadily deteriorating,
• debt covenants are becoming tight,
• cash-flow forecasts are routinely missed,
• capital expenditure is continually deferred because cash is unavailable,
• the business cannot absorb a modest downturn,
• owners cannot take normal distributions without borrowing,
• banks require increasing security,
• refinancing becomes more difficult,
• management spends increasing time managing cash crises,
• growth requires progressively larger borrowings without proportionate cash generation, or
• the business would struggle badly if its largest customer paid 30 days late.

One warning sign alone does not necessarily mean a business is overleveraged.

Several occurring together should prompt a serious review.

As discussed in my article on the early warning signs of business decline, deterioration is often visible well before a business reaches crisis point.

The problem is that owners do not always respond while they still have options.

The best time to restructure debt is usually before the bank believes you need to.

A Practical SME Debt Capacity Framework (Business Advisor Perth)

There is no single formula that will tell every SME owner exactly how much debt is optimal.

What is required is a disciplined framework that brings together purpose, affordability, leverage, cash flow, downside risk, security and strategic flexibility.

Before taking on material new debt, work through the following eight questions.

1. What Exactly Is the Debt Funding?

Start with purpose.

Ask:

What are we borrowing for, and how will this borrowing improve the economic position of the business?

The answer should be specific.

“Growth” is not specific enough.

A stronger answer might be:

We are borrowing $750,000 to purchase additional equipment that will increase productive capacity by 25%, eliminate approximately $180,000 of annual subcontracting expenditure and allow us to service contracted demand that we currently cannot accommodate.

That proposition can be analysed.

Management can estimate:

• incremental revenue,
• incremental gross profit,
• cost savings,
• additional operating costs,
• working-capital requirements,
• capital expenditure,
• repayment obligations,
• payback period, and
• return on invested capital.

The same discipline should apply whether the proposed borrowing funds equipment, inventory, property, expansion or an acquisition.

If management cannot clearly articulate how the borrowed capital will generate an acceptable economic return, the borrowing proposition should be challenged.

2. What Is the True Cash Requirement?

Do not simply borrow the purchase price.

Consider the complete cash requirement.

An expansion costing $1 million in equipment might also require:

• $300,000 additional inventory,
• $250,000 additional receivables,
• $150,000 recruitment and training expenditure,
• $100,000 implementation expenditure, and
• $200,000 contingency funding.

The actual funding requirement may therefore be substantially larger than the headline investment.

This is where robust strategic planning and financial modelling become essential.

Underfunding an otherwise attractive growth strategy can be just as dangerous as borrowing too much.

3. What Does the Business Look Like After the Debt?

Calculate the resulting:

• total debt,
• net debt,
• debt-to-equity,
• debt-to-EBITDA,
• interest coverage,
• debt-service coverage,
• available banking facilities,
• cash reserves, and
• covenant headroom.

Do not look only at the new loan.

Look at the entire post-transaction capital structure.

4. Can the Business Service the Debt From Sustainable Cash Flow?

The word sustainable matters.

Do not base debt capacity on:

• an unusually strong month,
• one exceptional contract,
• temporary government support,
• one-off profits,
• aggressive EBITDA adjustments,
• expected synergies that have not yet been achieved, or
• optimistic forecasts unsupported by evidence.

Normalise the earnings.

Then assess debt against the earnings and cash flow the business can reasonably expect to generate across the cycle.

5. What Happens in the Downside Case?

Stress-test:

• revenue,
• gross margin,
• wages,
• overheads,
• debtor days,
• inventory,
• interest rates,
• capital expenditure, and
• customer concentration.

Then combine several adverse assumptions.

The question is not:

“Can the business survive one thing going wrong?”

It is:

“Can the business remain financially viable when several reasonably foreseeable things go wrong at once?”

That is a much more realistic test of financial resilience.

6. What Security and Guarantees Are Being Given?

Understand the complete security package.

Do not assess a loan purely on:

• headline interest rate,
• establishment fee, or
• monthly repayment.

Also assess:

• personal guarantees,
• mortgages,
• general security agreements,
• cross-collateralisation,
• financial covenants,
• information requirements,
• events of default,
• restrictions on distributions,
• refinancing conditions, and
• early repayment provisions.

The cheapest facility is not necessarily the best facility.

7. What Strategic Flexibility Remains?

This question is frequently overlooked.

Suppose an SME uses almost all its borrowing capacity today.

What happens if, six months later:

• a competitor becomes available for acquisition,
• a strategically important property comes onto the market,
• a major customer offers a substantial new contract requiring working capital,
• equipment unexpectedly needs replacing, or
• trading conditions deteriorate?

A business with unused debt capacity and strong liquidity has options.

A highly leveraged business may not.

Financial capacity is therefore also strategic capacity.

8. What Is the Plan for Reducing the Debt?

Before borrowing, ask:

How does this debt ultimately get repaid?

Through:

• operating cash flow,
• asset sale,
• scheduled amortisation,
• retained earnings,
• refinancing,
• sale of the business, or
• some combination?

“Refinance it later” is not, by itself, a robust repayment strategy.

The SME Debt Traffic Light (Business Improvement Perth)

A simple traffic-light framework can help owners and Boards identify when leverage deserves greater scrutiny.

These are diagnostic indicators rather than universal banking thresholds. Appropriate ratios differ substantially between industries, business models and lenders.

A business with one amber indicator is not necessarily in trouble.

A business with six or seven amber indicators deserves attention.

A business with multiple red indicators should not be asking:

“How much more can we borrow?”

It should be asking:

“Why has the financial structure become this vulnerable, and what do we need to change?”

Debt Is Only One Source of Capital (Business Growth Perth)

Owners sometimes approach financing as though the decision is simply:

Borrow or don’t borrow.

In reality, businesses have a broader range of funding choices.

Depending on circumstances, these may include:

• retained earnings,
• shareholder capital,
• new external equity,
• bank debt,
• asset finance,
• invoice finance,
• working-capital facilities,
• vendor finance,
• strategic investors,
• joint ventures, or
• combinations of these.

Each has advantages, disadvantages and different implications for cost, control, risk and flexibility.

My article on funding options for your business considers these alternatives in greater detail.

Debt has an obvious attraction.

Unlike equity, it generally does not dilute ownership.

But retaining 100% ownership of an overleveraged business is not necessarily superior to owning a smaller percentage of a financially resilient, well-capitalised and substantially more valuable business.

Capital structure should therefore be designed around the strategic objective, not owner instinct alone.

When Should You Reduce Debt?

Just as there are times when borrowing is sensible, there are times when deleveraging should become a priority.

Consider reducing debt when:

• leverage has risen materially,
• earnings have become less predictable,
• interest coverage has deteriorated,
• the industry outlook has weakened,
• major customer concentration has increased,
• refinancing risk is approaching,
• personal guarantees have become uncomfortable,
• significant succession or ownership changes are approaching,
• the business is preparing for sale, or
• management simply wants greater strategic flexibility.

Debt reduction does not necessarily mean abandoning growth.

It can involve:

• retaining more earnings,
• improving margins,
• reducing working capital,
• selling surplus assets,
• disposing of non-core operations,
• renegotiating repayment profiles,
• raising equity, or
• slowing capital expenditure temporarily.

The objective is not necessarily zero debt.

The objective is an appropriate balance between return and resilience.

Improving Working Capital May Be Better Than Borrowing More (Business Improvement Perth)

Before increasing borrowings, ask whether the business can release cash internally.

Suppose annual revenue is $20 million.

Reducing debtor days by only 10 days could potentially release approximately:

$548,000 of cash, before allowing for GST and other factors.

Reducing excess inventory might release another $300,000.

Negotiating more appropriate supplier terms could further improve liquidity.

Suddenly, what appeared to be a requirement for another $1 million bank facility may look very different.

This is why strong business performance is interconnected.

Pricing affects margins.

Margins affect EBITDA.

EBITDA affects debt capacity.

Debtor collection affects cash.

Inventory affects cash.

Capital expenditure affects cash.

Debt affects interest.

Interest affects profit.

Profit affects retained earnings.

Retained earnings affect equity.

Equity affects leverage.

Financial performance is a system, not a collection of isolated numbers.

That is precisely why business performance improvement should address the underlying business levers rather than treating cash shortages as purely financing problems.

Governance Matters More as Debt Increases (Governance & Boards)

The more leveraged a business becomes, the less tolerance it has for poor decisions.

A debt-free company with substantial cash reserves may survive several management mistakes.

A highly leveraged business may not.

Debt therefore increases the importance of:

• accurate monthly financial reporting,
• cash-flow forecasting,
• budgeting,
• covenant monitoring,
• scenario analysis,
• capital expenditure approval,
• disciplined distributions,
• Board oversight, and
• accountability.

This is where effective business governance becomes highly practical rather than bureaucratic.

For businesses carrying material leverage, the Board or advisory structure should routinely see:

• cash balance,
• undrawn facilities,
• total debt,
• net debt,
• debt maturity profile,
• interest cost,
• debt-to-EBITDA,
• interest coverage,
• debt-service coverage,
• covenant position,
• aged receivables,
• inventory,
• cash-flow forecast, and
• downside scenarios where circumstances warrant them.

The purpose is not to generate more reports.

It is to prevent unpleasant surprises.

An experienced independent Non-Executive Chairman can also add value where significant financing decisions require challenge, discipline and an independent perspective.

Ten Practical Recommendations for SME Owners Considering Debt

Before taking on significant new borrowing:

1. Define the purpose clearly. Know exactly what the borrowed money will fund and how it is expected to create value.
2. Prepare an integrated forecast. Profit and loss, balance sheet and cash flow should tell the same financial story.
3. Calculate the important ratios. Understand debt-to-EBITDA, interest coverage, DSCR and liquidity before and after borrowing.
4. Stress-test the assumptions. Model lower revenue, lower margins, slower collections and higher interest rates.
5. Protect financial headroom. Do not use every dollar of borrowing capacity simply because it is available.
6. Match finance to purpose. Avoid funding long-lived assets with facilities that may be repayable or renewable in the short term without a clear refinancing strategy.
7. Understand every guarantee and security. Know precisely what happens if the business cannot repay.
8. Monitor debt monthly. Debt management should be part of the management dashboard, not something reviewed only when the bank calls.
9. Consider alternatives. Compare debt with retained earnings, equity, asset finance and other appropriate sources of capital.
10. Get independent advice before the decision becomes irreversible. Major financing decisions warrant challenge from someone who is not emotionally committed to the proposed investment.

The Question Is Not “How Much Debt Can We Get?” (Business Advisor Perth)

Perhaps the most important shift in thinking is this:

Stop allowing the lender’s appetite to determine your business’s appetite for risk.

The bank may offer $5 million.

Your business may prudently need only $3 million.

Or the opposite may be true: the business may need $5 million to execute the strategy safely, and attempting the project with $3 million may leave it dangerously undercapitalised.

The correct number comes from understanding:

strategy + cash flow + leverage + downside risk + security + flexibility + return.

That is a capital allocation decision.

And capital allocation is one of the most important responsibilities of an owner, CEO and Board.

Key Takeaways

• Debt is neither inherently good nor bad. Its value depends on purpose, structure, affordability and risk.
• Borrowing capacity is not the same as prudent debt capacity. A lender’s willingness to advance money does not determine what is optimal for your business.
• Cash flow services debt, not accounting profit. Profitable businesses can still fail because they run out of cash.
• No single leverage ratio tells the whole story. Debt-to-equity, debt-to-EBITDA, interest coverage, DSCR, liquidity and covenant headroom should be considered together.
• Stress-testing is essential. Significant debt should remain manageable under reasonably foreseeable adverse conditions, not merely the base forecast.
• Working capital can consume enormous amounts of cash. Rapid growth can increase borrowing requirements even while profits rise.
• Personal guarantees change the nature of business debt. Owners need to understand precisely how much personal wealth is exposed.
• Refinancing is a risk, not an assumption. Future credit conditions may differ substantially from today’s.
• Financial headroom creates strategic freedom. Unused capacity can be enormously valuable when opportunities or problems emerge unexpectedly.
• The optimal debt level is not necessarily the lowest possible debt level. The objective is to balance growth, shareholder returns, resilience and flexibility.

Frequently Asked Questions

What is a good debt-to-equity ratio for an SME?

There is no universally appropriate ratio. Capital-intensive businesses, professional services firms, property businesses and cyclical companies can have very different sustainable capital structures. Debt-to-equity should be assessed alongside cash-flow stability, asset backing, profitability, interest coverage, debt maturity and industry risk.

What is a good debt-to-EBITDA ratio?

Again, there is no universal figure. A ratio that is comfortable for a stable recurring-revenue business may be inappropriate for a highly cyclical company. The trend, quality of EBITDA, cash conversion, debt terms and downside resilience are as important as the headline multiple.

Is having no business debt always best?

No. A debt-free balance sheet can provide exceptional resilience, but avoiding all debt may also cause an owner to reject attractive investments or tie excessive equity capital into the business. Appropriate leverage can improve capital efficiency and support growth.

When does business debt become dangerous?

Debt becomes particularly dangerous when servicing depends upon optimistic forecasts, liquidity is tight, earnings are volatile, covenants have little headroom, refinancing options are limited or the business requires new borrowing merely to meet existing obligations.

Should I borrow to fund business growth?

Potentially, provided the growth is economically attractive, working-capital requirements are understood, the debt can be serviced under downside conditions and the business retains adequate liquidity.

Debt should finance sound growth, not compensate for an unsound strategy.

Should I use debt to buy another business?

Debt can be an effective acquisition-financing tool, but the analysis should be based on sustainable post-acquisition cash flow and conservative assumptions. Integration costs, customer losses, working-capital requirements and delayed synergies should be stress-tested.

What is DSCR?

The Debt Service Coverage Ratio compares cash available for debt service with required principal and interest payments. It provides an indication of the financial headroom available to meet scheduled debt commitments.

The exact calculation may differ between lenders, so always understand the definition contained in your finance documents.

Should I use an overdraft to buy equipment?

Generally, long-lived assets should be matched with appropriately structured longer-term finance rather than relying on a short-term working-capital facility. The appropriate structure depends on the business, asset and financing terms.

Is a personal guarantee normal for SME lending?

Personal guarantees are common in some forms of SME lending, but that does not make them insignificant. Owners should understand the scope, duration, assets exposed, release conditions and legal consequences before signing.

What happens if my business breaches a banking covenant?

The consequences depend on the finance agreement. A breach may give the lender various contractual rights, potentially including requiring information, imposing conditions, renegotiating terms or exercising default rights. Obtain professional advice early if a breach is approaching rather than waiting until after it occurs.

Should I pay debt down or reinvest in growth?

Compare the risk-adjusted return available from reinvestment with the financial benefit and risk reduction from reducing debt. The answer will depend on leverage, interest rates, investment opportunities, liquidity requirements and the owner’s objectives.

How often should SME debt levels be reviewed?

Material debt should normally be monitored through regular management reporting, with a deeper review during budgeting, strategic planning, major capital expenditure, acquisitions, refinancing and periods of material change.

What should I do if my business already has too much debt?

Act early.

Develop an accurate cash-flow forecast, understand the causes of the problem, engage constructively with lenders where necessary and examine working-capital improvement, cost reduction, asset sales, equity injection, refinancing, restructuring and operational performance improvement.

The longer an owner waits, the fewer options may remain.

Conclusion, The Best Debt Structure Lets You Sleep at Night and Still Seize Opportunity (Business Advisor Perth)

The objective of financial management is not to eliminate risk.

Business itself involves risk.

The objective is to take intelligent, understood and appropriately rewarded risk without creating a financial structure so fragile that one setback threatens everything the owner has spent years building.

Debt can be enormously valuable.

It can accelerate growth.

It can improve returns on equity.

It can fund acquisitions.

It can purchase productive assets.

It can bridge working-capital cycles.

And it can allow owners to retain equity rather than dilute their ownership.

But leverage works in both directions.

When things go well, debt can magnify shareholder returns.

When things go badly, it can magnify losses, consume cash, restrict choices and transfer negotiating power from the owner to creditors.

That is why the most important question is not:

“How much debt can I get?”

Nor is it:

“How little debt can I possibly have?”

The better question is:

“What level and structure of debt gives this business enough capital to pursue its strategy, while leaving enough financial resilience to survive when the future does not unfold according to plan?”

Finding that balance is what prudent capital management is really about.

For SME owners facing significant borrowing, refinancing, expansion, acquisition or capital-structure decisions, an experienced independent Business Advisor Perth can provide an external perspective on the strategy, forecasts, assumptions, risks and alternatives before commitments are made.

Where the financing decision forms part of a broader strategic challenge, a Fractional CEO Perth can also help translate the financing decision into strategy, execution, performance management and accountability.

Because the best time to discover that your business has too much debt is before you take it on, not when the bank, the cash-flow forecast or the market tells you that you do.
