Quick answer
Serviceability is a lender's assessment of whether a borrower's income can comfortably cover the repayments on a proposed loan, on top of every existing commitment. For business loans it's usually measured from profit or bank statement cash flow, often expressed as a debt service coverage ratio. Strong security can't replace weak serviceability at a bank, but some property-secured lenders weigh it differently.
Key points
- Answers one question: can this business pay the loan back from its own income?
- Banks usually measure it from tax returns and financial statements; fintech lenders from bank statements
- Existing debts, tax arrears and personal commitments all reduce the surplus a lender counts
- Property-secured lenders may accept thinner serviceability when there's a clear exit strategy
Every lender, from a big four bank to a private funder, eventually asks the same thing: if we lend you this money, where do the repayments come from? Serviceability is the name for that question and for the calculation that answers it. A loan “services” when the borrower’s reliable income covers the new repayments and everything already owed, with room left over for a bad month.
How do lenders measure serviceability?
The method depends on the lender and the product, but the logic is similar everywhere. The lender estimates income available to repay debt, subtracts commitments, and checks whether the proposed repayment fits inside what’s left.
| Lender type | What it reads | How it tends to test |
|---|---|---|
| Banks | The last two lodged returns, accountant-prepared accounts and year-to-date figures | Net profit with add-backs, repayments tested at a buffered cost, minimum coverage ratio |
| Non-bank lenders | Accountant’s letter, BAS or bank statements on low doc products | Similar maths, with more flexibility on the paperwork used |
| Fintech unsecured lenders | Recent business bank statements, often pulled electronically | Repayment as a share of average deposits; flags dishonours and other lenders |
| Private and caveat lenders | Security value and repayment plan | Less weight on income; more on the exit strategy |
Banks often express the result as a debt service coverage ratio: cash available for debt divided by total debt repayments. A ratio of 1.0 means every dollar of surplus goes to repayments, with nothing spare. Lenders want comfortably more than that, and each sets its own minimum.
A worked example
A Geelong landscaping company wants a $180k equipment and working capital loan. The lender’s figures for the past year:
- Net profit before tax: $96,000
- Add back depreciation ($22,000) and interest on a vehicle loan being refinanced ($6,000)
- Cash available for debt: $124,000 a year
Commitments the lender counts:
- Proposed new loan repayments: $52,000 a year
- Existing ute and trailer finance staying in place: $14,000 a year
- The full $30k overdraft limit, assessed as a notional $4,000 a year in repayments even though it’s rarely drawn
Total debt repayments: $70,000. Coverage is $124,000 ÷ $70,000, about 1.77. That sits well above most bank minimums, so on serviceability alone the loan looks sound. If the overdraft were $150k instead, or profit had dipped the previous year, the picture could change quickly.

What weakens serviceability?
The common culprits are rarely dramatic:
- Unused limits. Credit cards and overdrafts are counted at their limit, not their balance.
- Tax arrears. An ATO payment plan is a commitment and comes off the surplus.
- Stacked short-term loans. Daily or weekly repayments to several online lenders add up fast.
- Out-of-date financials. If the latest return shows an old, weaker year, that’s the year a bank tests.
- Personal debts. For sole traders and guarantors, home loan and car repayments count too.
Clearing a dormant credit card or reducing an overdraft limit before applying can genuinely improve the result.
When serviceability isn’t the whole story
Banks are often the cheapest source of business money, and when your numbers service comfortably their offer deserves serious attention. When they don’t, that isn’t always the end. Secured business loans from non-bank and private lenders can lean more on property equity and a credible repayment plan, while low doc business loans accept alternative evidence of income.

Wondering if your loan will service?
Coverage ratios and add-backs are easier to judge with a second pair of eyes. Give us a minute on the enquiry form and a specialist who tests serviceability for a living will go over your figures, then ring you to talk it through. Sending it doesn’t trigger a credit enquiry, and nobody passes your file around a crowd of funders. Put in your real turnover and every existing repayment, including that overdraft you never touch, because that’s exactly what a lender will count and it lets us match you to the right test on the first go.
Frequently asked questions
What's the difference between serviceability and borrowing power?
Serviceability is the test; borrowing power is the result. A lender works out how much surplus income you have after existing commitments, then calculates the largest loan whose repayments fit inside that surplus with a safety margin. That figure is your borrowing power with that lender.
Do lenders count add-backs when testing serviceability?
Many do. Non-cash expenses like depreciation, interest on debts being refinanced, and one-off costs can often be added back to profit, because they don't reduce the cash available for the new loan. Each lender has its own list, so ask your accountant to show add-backs clearly.
Why did my bank say the loan didn't service when my business is profitable?
Banks usually test repayments at a higher assumed cost than the actual loan, include every existing limit even if unused, and may average two years of results. A good current year can be dragged down by a weaker prior year, or a large unused overdraft can eat into the surplus.
Can I get a business loan if it doesn't service on paper?
Sometimes. Some private and property-secured lenders focus on the equity in the security and the plan to repay, such as selling an asset or refinancing once accounts are updated. These loans are usually short term and cost more, so the repayment plan needs to be realistic.
How do unsecured lenders check serviceability?
Most fintech and non-bank unsecured lenders read six to twelve months of business bank statements, looking at average deposits, regular outgoings, dishonours and existing lender repayments. The loan is sized so the daily or weekly repayment is a manageable share of typical takings.
