The financial year just closed on a genuinely good result, so the equipment finance application or the facility increase request feels like a formality. Then the bank comes back with a smaller number than expected, or asks for more information, or takes weeks longer than anyone budgeted for. The owner is left looking at a healthy profit figure wondering why it didn’t do more of the talking.
The answer is that profit and serviceability are two different tests, and lenders only care deeply about the second one. Profit tells a bank the business made money over a period. Serviceability tells them whether the business generates enough reliable cash, month after month, to cover the interest and principal on top of everything else it already owes, without stretching. A business can pass the first test comfortably and fail the second, and most owners only discover the gap when they’re sitting across from a lender rather than before.
It’s worth understanding what that calculation actually looks like, because it’s not complicated, and it’s something an owner can run on their own numbers well before an application ever goes in.
What the bank is actually calculating
Underneath the credit assessment, lenders are asking one question in different forms: after everything else is paid, is there comfortable headroom left to cover this debt, even in a quieter month. They start from earnings before interest, tax, depreciation and amortisation, then weigh that against the interest and scheduled principal on existing debt plus whatever is being applied for. They’re not looking for the number to merely clear the line. They’re looking for headroom, because a business that only just covers its repayments has no buffer if a customer pays late, a quiet quarter turns up, or a cost line moves against them.
This is also why two businesses with identical annual profit can get very different answers from the same lender. One carries little existing debt and steady, predictable cash flow. The other is already servicing a vehicle fleet, a lease and a line of credit, with revenue that swings hard by season. The profit line looks the same. The serviceability picture doesn’t.
Why a genuinely profitable year can still fail the test
Three things quietly work against serviceability even in a strong year. The first is working capital movement. Profit is an accounting figure, and it doesn’t account for the cash sitting in debtors, stock or work in progress at balance date, cash that’s real on the P&L but not sitting in the account to service anything. The second is existing debt load carried at a level the owner hasn’t recently revisited, particularly finance taken on when rates or terms were different to today’s. The third is owner drawings and discretionary spend that sit above the line in a way that understates what the business would actually need to cover if circumstances tightened.
None of this means the business is poorly run. It usually means the serviceability picture has never been calculated deliberately, only implied by a profit figure that tells a different, simpler story. That’s a common gap, not a sign anything has been done wrong, and it’s exactly the kind of thing a banking and facility review is built to surface before a lender does.
Running the check before the bank does
The version an owner can do without a lender in the room starts with EBITDA for the last twelve months, then lists every existing debt obligation, its interest and its scheduled repayment, not just the interest component. Add the new facility being considered to that list at a realistic rate. What’s left is the headroom, and the more comfortably positive that number sits, the stronger the position walking into the conversation. It’s also worth stress testing it against a slower month rather than the annual average using a proper cash flow forecast, since lenders will do exactly that, and a business that only services debt comfortably in its best months is carrying more risk than the P&L suggests.
This is also a useful discipline even when no finance application is on the table. Interest rates move, debt gets added over years without anyone stepping back to look at the total picture, and a business that tracks its own serviceability regularly walks into any lender conversation, capital raise, or growth decision from a position of knowing the number rather than hoping it holds up. If a facility increase, equipment upgrade or refinance is on the horizon for the year ahead, it’s worth having that number calculated properly before the application goes in rather than after the bank comes back with questions. You can book a discovery call to talk through what that would look like for your business.
Frequently asked questions
What is a debt serviceability ratio and why do banks use it?
It measures whether a business generates enough earnings to cover the interest and principal on its debt, existing and proposed, with a comfortable margin left over. Banks use it because profit alone doesn’t show whether repayments can be met reliably through quieter months, which matters more to a lender than the annual average.
Why would a bank decline finance for a business that is clearly profitable?
Profit and serviceability are assessed differently. A business can report a strong result on paper while carrying enough existing debt, working capital swings or seasonal cash flow variation that a lender sees limited headroom to cover a new facility. A banking and facility review is designed to surface that gap before an application goes in.
How do I calculate my business’s serviceability before applying for finance?
Start with EBITDA over the last twelve months, then list the interest and scheduled principal on every existing debt obligation, adding the new facility at a realistic rate. What remains is the headroom. Testing that figure against a slower month rather than the yearly average gives a more honest picture of where the business actually sits.
Does seasonal cash flow affect how a lender assesses an SME loan application?
Yes. Lenders generally want to see that repayments can be comfortably met even in a business’s quieter months, not just across the annual average. A business with strong peak-season trading but tight off-season cash flow needs to demonstrate that gap is manageable, which is where a rolling cash flow forecast becomes useful evidence.
When should an Australian SME review its existing banking facilities?
Any time before a new finance application, at least annually as a matter of discipline, and whenever interest rates or the business’s debt load have shifted meaningfully since the facility was last reviewed. Many owner-led businesses carry finance arranged years earlier without revisiting whether the terms or structure still suit the business today.
What is a good interest cover level for a small or medium business in Australia?
There’s no single figure that fits every industry or lender, since risk appetite and business type both matter. The more useful discipline is comparing your own headroom against a quieter trading month rather than chasing a specific benchmark, since that’s closer to how a lender will actually stress test the number.
Can a fractional CFO help prepare a business for a finance or facility application?
Yes. A fractional CFO partnership typically includes preparing the financial picture a lender will actually assess, including serviceability, working capital movement and existing debt load, before an application goes in. That preparation tends to shorten the process and can improve the terms on offer compared with applying on the raw numbers alone.
