Quick answer
Serviceability is the room left in the business after its normal costs and existing repayments. An assessor works out typical monthly income from your statements, subtracts costs and current commitments, and checks that a new repayment fits with a sensible buffer. You can do the same sum yourself in minutes, using your own statements and a debt list.
Key points
- Serviceability is a room-left test, not a mystery score.
- The sum: typical income, minus costs, minus existing repayments.
- A buffer matters because months are never identical.
- Cost of the new loan is the lender's to work out; you supply the facts.
- The sum
- Income - costs - existing repayments = room
- Your inputs
- Statements, debt list, typical costs
- No rates needed
- The test is about room, not pricing
What is serviceability, in one breath?
It is room. The business brings in money, pays its costs, meets its existing repayments, and what is left is the room available for something new. When that room is comfortable, the business can carry the new repayment; when it is a sliver, it cannot. That is the entire concept. The rest is arithmetic and judgement about how much room is enough.
business.gov.au’s advice to anyone preparing for a loan is to work out the most you can afford to repay, and to understand your income, expenses, debts and cash flow. That is serviceability stated in everyday words. An assessor does the same sum from the other side, using your documents.
How does the sum work?
Four lines, top to bottom.
| Line | What goes in | Where the assessor finds it |
|---|---|---|
| Typical monthly income | Deposits that are genuine revenue, not transfers | Bank statements, BAS |
| Less: operating costs | Wages, rent, stock, fuel, insurance and so on | Statements, financials |
| Less: existing repayments | Every loan, lease and plan instalment | Debt list, statements |
| Less: owner drawings | What you take out to live on | Statements |
| Equals: room left | What a new repayment would come from | The result |
Notice what is missing: any interest rate for the new loan. Working out the new repayment is the lender’s job once the facts are known, and pricing depends on your situation. Your job is to make sure the room-left figure is accurate and honestly presented.
Why does “typical” matter more than “best”?
Because months vary. A business that earns well in November and thinly in February is not rare, and an assessor will tend to use an average or a conservative month, not the peak. If you present peak-month figures as typical, the assessor will recalculate, and the recalculation will be less flattering than an honest presentation.
Seasonality is not a weakness if it is explained. A cover note that says “Q4 is roughly 40 per cent stronger than Q1; here are the last two years” does the assessor’s work for them.
What if profit and cash disagree?
They often do, and for ordinary reasons: a customer pays late, stock was bought ahead of a sale, a big equipment purchase went through the books over several years but came out of the bank at once. An assessor uses profit to judge viability and cash to judge capacity, and where they differ they ask why.
Have the answer ready. The page on reading your financials like an assessor covers the common reasons for a gap, and how to explain them concisely.
Illustrative example. A landscaping business shows a tidy profit on its accounts but thin statements. The reason: it prepays plant stock in winter and gets paid in spring. The cover note explains the cycle, with two years of statements to prove it repeats. The room-left test is judged on the full-year average, not on the winter low.
What can I do to widen the room?
Sometimes there are simple moves:
- Clear a lingering small debt or cancel a facility you do not use.
- Settle an ATO balance or tidy a payment plan (see ATO payment plans from a lender’s point of view).
- Cut a recurring cost that is not earning its keep.
- Stop drawing lumpy amounts and move to a steady pay.
None of this is a trick. They are changes that make the business more robust whether or not you borrow. A specialist can say which, if any, are worth doing for your particular situation.
How do I run the sum on my own business?
Take your last three or six months of statements, strip out transfers and one-offs, and total the real income. Take the same months and total the costs. Add up your repayments from the debt list. The application readiness check prompts you for the inputs in a simple order, and its result tells you whether serviceability looks like a strength or something to prepare for.
What does a thin or a generous result look like?
Think of room left as a share of monthly income. If a business takes in a certain amount each month and, after every cost and existing repayment, keeps a healthy slice, there is room. If almost nothing remains, there is not. The exact threshold varies by lender and product, so treat this as a feel for the shape rather than a rule.
A generous result usually has three signs: income that is steady, costs that are predictable and existing commitments that are modest against turnover. A thin result usually has the opposite: lumpy income, fixed costs that eat most of it and several repayments already in place. Many businesses sit somewhere in between, and that is where explanation and structure matter most.
What would change the answer?
Three levers move the result. The first is the amount: a smaller facility needs less room. The second is the structure: a facility that is drawn only as needed behaves differently from one paid out in full. The third is the evidence: documented, contracted income is weighted more confidently than hoped-for income. A specialist can walk through which of these is worth pulling for your file, which is one more reason to talk before assuming the answer.
Ready to lodge?
If your room-left figure looks healthy, or at least honest, lodge a free enquiry. It takes around a minute, won’t touch your credit file at this stage, and goes to a real person who will read your situation, not to a crowd of lenders.
Please give accurate figures on the form, including your trading history and the amount you want. That accuracy is what lets the first conversation be about what fits your numbers rather than about fixing them.
Frequently asked questions
What is the simplest way to explain serviceability?
It is whether the business has room to carry the repayment. If normal income less normal costs less existing repayments leaves comfortable space, there is room. If it leaves a sliver, the room is thin.
Does serviceability depend on profit or on cash?
Both are looked at. Profit shows the business is viable on paper; cash shows whether money is actually available month to month. Where they differ, the assessor will ask why.
Why do lenders use a buffer?
Because real months vary. A repayment that fits only in your best month is risky, so assessors tend to want room even in an average one.
Do owner drawings count?
Yes. Money you take out to live on is an outgoing from the business's point of view, and an assessor will look at what is drawn. Consistent, modest drawings are easier to read than lumpy ones.
Can I improve serviceability before I lodge?
Sometimes. Paying off a small liability, clearing a lingering ATO balance or reducing a recurring cost can all widen the room. The effect on your file is what counts, and a specialist can tell you what is worth doing.
