Most business owners think about debt as one thing, either good or bad

Ask most business owners how they feel about debt and the answer tends to be some version of “try to avoid it.” It’s a reasonable starting position, borrowing does carry real risk, but treated as a blanket rule, it causes two problems. Some owners avoid finance that would genuinely support their growth, funding a piece of equipment that pays for itself, or a facility that smooths a seasonal cash flow cycle, because they’ve been taught debt is inherently something to minimise. Others take on debt without examining it closely at all, because the immediate need feels urgent enough to override the question of whether it’s the right decision.

Why “debt is risky” is a rule of thumb, not a financial principle

As a rule of thumb, “avoid debt” is simple and generally safe. As a financial principle, it doesn’t hold up, because it treats all borrowing as equivalent regardless of what it funds, how it’s structured, or what it costs relative to the return it generates. A rule of thumb is useful when you don’t have time to think something through properly. A business decision usually deserves more than that.

Where the good debt vs bad debt distinction actually comes from

The distinction isn’t about the size of the debt or even the interest rate. It’s about whether the borrowing funds something that creates value greater than its cost, and whether the business is genuinely positioned to service it. Once you apply that lens, the same dollar figure can be either a smart decision or a serious risk, depending entirely on the context around it.

What separates good debt from bad debt

Does it fund something that generates a return, or something that doesn’t

Good debt typically funds something productive: equipment that increases output, a property that appreciates or replaces rent, working capital that supports a growth opportunity already in motion. Bad debt tends to fund consumption, or a gap, without a corresponding return. The test isn’t complicated: what does this borrowing actually produce for the business?

Does the repayment timeline match the life of what it’s funding

A five-year asset funded over five years makes sense. A five-year asset funded over fifteen years, or an ongoing cash flow shortfall funded with a short-term facility that needs to be refinanced every few months, is a mismatch, and mismatches are where good intentions turn into problems.

Can the business service it comfortably, or does it rely on best-case cash flow

Debt that only works if everything goes to plan, no slow months, no late-paying customers, no unexpected costs, is fragile by design. Good debt is structured with enough headroom that a normal bad month doesn't put the business in breach of its obligations.

What good debt looks like in practice

Financing equipment or assets that increase capacity or efficiency

A piece of machinery that lets a business take on more work, reduce labour costs, or improve output quality is a textbook example of debt funding a return. As long as the numbers stack up, the financing cost is simply the price of accessing that return sooner than retained earnings alone would allow.

Funding growth that’s already backed by demand; a contract, an order book, an expansion plan

Debt used to fund growth that's already validated, a signed contract requiring additional staff or stock, an order book that justifies expansion, is fundamentally lower risk than debt funding speculative growth. The demand already exists; the finance simply bridges the timing gap between outlay and revenue.

Structured working capital that smooths cash flow rather than masking a shortfall

A working capital facility used deliberately to manage the natural lag between paying suppliers and collecting from customers is a legitimate and common use of debt. The distinction is whether it's a planned tool for managing a known cycle, or an unplanned response to a shortfall that keeps recurring without being addressed.

What bad debt looks like in practice

Borrowing to cover recurring shortfalls without addressing the underlying cause

If a business needs to borrow to cover the same gap every quarter, the debt isn’t solving the problem, it’s delaying it, and usually adding cost on top. Recurring reliance on debt to cover a shortfall is a signal that something structural, pricing, cost base, debtor days, needs attention, not just financing.

Short-term, high-cost finance used for long-term needs

Using a short-term facility, often at a higher cost, to fund something that should really be financed over several years is a common and expensive mistake. It usually happens because the short-term option was faster or easier to access, not because it was the right fit.

Debt taken on reactively, without a clear plan for how it gets repaid

Debt taken on to solve an immediate problem, without a clear view of how it will be repaid or what changes to make repayment sustainable, tends to create a second problem down the track. The absence of a repayment plan is often a bigger warning sign than the size of the debt itself.

Why structure matters as much as the decision to borrow

Matching the loan term to the asset or purpose it's funding

Term length should reflect the useful life of whatever’s being funded. Equipment finance matched to the equipment’s working life, property finance matched to a long-term hold, working capital structured as a revolving facility rather than a fixed term loan, each of these alignments reduces the risk that the debt outlives its usefulness or gets repaid faster than the business can comfortably manage.

The risk of using short-term facilities to fund long-term needs, and vice versa

Funding a long-term need with short-term debt creates refinancing risk, the facility may need to be renewed on less favourable terms, or not at all. Funding a short-term need with long-term debt often means paying for finance longer than necessary. Both are structural mismatches that turn an otherwise reasonable decision into an avoidable risk.

How the wrong structure can turn a reasonable decision into a bad debt

The same borrowing decision, for the same purpose, can be either good or bad debt depending entirely on how it's structured. This is why the structure deserves as much attention as the decision to borrow in the first place, and why two businesses making the same choice can end up with very different outcomes.

The questions that separate good debt from bad debt before it's taken on

What return or outcome will this generate that exceeds its cost

If the answer isn’t clear, that's worth pausing on before proceeding. Good debt has a reasonably identifiable return, more revenue, lower costs, avoided downside, that exceeds what the finance costs to service.

What happens to the business if the expected return doesn't materialise

Every growth plan carries some uncertainty. The question worth asking isn’t just “will this work,” but “can the business absorb it if it doesn’t work as well as expected.” Debt that only makes sense in the best-case scenario is a warning sign.

Is this decision reactive or planned?

Debt arranged ahead of a known need, with time to compare options and structure it properly, tends to produce better outcomes than debt arranged under pressure. This question alone often separates good debt from bad debt more reliably than any other factor.

Why this is a conversation for the accountant, not just the lender

A lender assesses whether the debt can be serviced

A lender’s job is to assess risk from their own position: can this business make the repayments. That's a narrower question than whether the debt is genuinely the right decision for the client’s broader circumstances, and it's not a question a lender is positioned, or incentivised, to answer.

How the accountant’s view of the business's broader position changes the advice

The accountant sees the client’s cash flow, tax position, other obligations, and future plans in a way no lender does. That vantage point is exactly what’s needed to assess whether a piece of debt fits the client’s overall position, not just whether it's approvable.

Structuring finance as part of the client's overall plan, not in isolation

Debt decisions rarely happen in isolation from everything else going on in a business. Considered alongside the client's broader plans, growth, other borrowing, tax position, a financing decision that looks reasonable on its own can look quite different, and vice versa.

Business debt isn’t inherently good or bad. What determines the outcome is what it funds, whether the structure matches the purpose, and whether it’s arranged as part of a plan rather than a reaction. Businesses that get this right use debt as a genuine growth tool. Businesses that don’t often discover the difference the hard way.
