Quick answer
Serviceability is a lender's test of whether your business can comfortably meet the repayments on a new loan, on top of everything it already pays. Lenders measure income, subtract existing commitments and apply a buffer for things going wrong. A loan that passes serviceability leaves room to spare; one that only just fits is often declined or reduced.
Key points
- Serviceability looks at income minus all commitments.
- Lenders add a buffer for rate rises and bad months.
- Existing debts are the biggest drag on capacity.
- Secured lenders can weigh security more heavily, but still care.
- Main inputs
- Turnover, profit, existing debts, the new repayment
- Evidence used
- Bank statements, BAS, financial statements
- Most common fix
- Consolidate debts or adjust term and amount
- Credit check to enquire
- None
A lender can love your business, your property and your plan, and still say no. When that happens, the reason is often serviceability. It’s the part of the assessment that asks a simple question with a lot of maths behind it: once this loan is added, can the company still pay every bill comfortably, including in a bad month?
What serviceability actually measures
At its core, serviceability compares what the business earns with what it must pay. Lenders estimate income available to repay debt, subtract existing commitments such as other loans, leases and tax obligations, and then check whether the new repayment fits inside what’s left with room to spare.
The “room to spare” part is critical. Lenders know that trading varies, costs rise and customers pay late. So they don’t approve a loan that only works on a perfect month. They apply a buffer, which might be a minimum surplus, a cover ratio or an assessed repayment higher than the actual one.
How different lenders measure it
Cash flow lenders typically work from business bank statements. They take average monthly deposits, look at the money going out, and set a maximum repayment as a share of turnover or surplus. This is quick and current, which is why it suits fast unsecured loans.
Banks and larger lenders often work from financial statements and tax returns. They calculate profit before interest, tax, depreciation and amortisation, add back one-off or non-cash items, and compare that to total debt repayments. This gives a fuller picture but relies on records that may be months old.
Private and short-term secured lenders can lean more on the property and the exit strategy. They still look at whether interest can be met, but a strong exit can make up for a tight monthly position over a short term.
What drags serviceability down
The single biggest factor is existing debt. Each loan, lease and credit card limit reduces what’s available for new borrowing, and lenders often assess credit limits as if they were fully drawn. Several short-term loans debiting daily or weekly can soak up capacity fast.
Other common drags include thin or falling profit margins, irregular income without a clear seasonal pattern, a large ATO debt or payment plan, and personal commitments of the directors when they are guaranteeing the loan.
Practical ways to improve your position
You can often lift serviceability without changing the business itself:
- Consolidate. Rolling several costly short-term debts into one longer facility can free up a lot of monthly cash. See refinancing business debt.
- Adjust the term. A longer term lowers each repayment, though it usually increases total cost.
- Change the repayment frequency. Matching repayments to your income cycle makes the loan easier to carry. Our page on repayment frequency explains the options.
- Close unused limits. Credit cards and overdrafts you don’t use still count against you.
- Add security. Property security can open longer terms and more flexible assessment.
- Bring your records up to date. Lodged BAS and recent financials can show stronger profit than old tax returns do.
A simple illustration
Imagine a café with average monthly deposits of $80,000. After rent, wages, stock, utilities and tax, around $9,000 a month is left over. It already pays $3,000 a month on an equipment loan. A lender might decide that only part of the remaining $6,000 should go to a new repayment, keeping the rest as a buffer for a slow month or a broken coffee machine. If the owner asks for a loan with a $5,500 monthly repayment, it probably won’t pass. Ask for one at $3,000, or consolidate the equipment loan into the new facility over a longer term, and the picture changes. The business hasn’t changed at all; only the structure has.
Why directors’ personal finances can matter
Most small company loans come with personal guarantees from the directors. When they do, some lenders also look at the directors’ own commitments, such as a home loan, car finance or credit cards. A director with heavy personal debt can drag down serviceability for an otherwise healthy company. If that applies to you, mention it early so the lender can factor it in properly rather than discovering it at the last step. Our page on director guarantees and security covers this in more detail.
How to gauge your own position
Before you apply, total up what the business pays each month for existing loans, leases and tax arrangements, and compare it with your average monthly surplus. If the new repayment would take most of what’s left, consider a smaller amount, a longer term or a consolidation first. Our borrowing power calculator gives an indicative range, and the repayment calculator shows how term and frequency change the monthly figure.

Frequently asked questions
Is serviceability based on turnover or profit?
Cash flow lenders often start with turnover from bank statements; larger lenders use profit from financial statements. Both are trying to answer the same question: what's left over after costs to repay a loan?
Why do lenders add a buffer?
To make sure the loan still works if trading dips or variable costs rise. A loan that only fits on a perfect month is a loan likely to go into arrears.
Can I pass serviceability with a lower amount?
Often, yes. Reducing the amount, extending the term or consolidating other debts can bring a loan within a lender's limits.
Do secured loans need to pass serviceability?
Usually, though some short-term private lenders put more weight on the security and exit. Even then, they'll want to see that interest can be met.
