How Is Serviceability Calculated?
Loan serviceability is a lender's assessment of your business's ability to comfortably afford ongoing loan repayments alongside existing debt and operating expenses.
What is loan serviceability?
Loan serviceability is a lender’s assessment of whether your business's cash flow can comfortably support new debt repayments. When evaluating a company, sole trader, or ABN holder, lenders analyze your net trading income alongside operational costs, ATO obligations, and existing commercial or personal liabilities to confirm you hold a healthy cash surplus.
Unlike standard PAYG wage assessments, calculating business serviceability requires looking at financial statements, tax returns, or BAS. Most Australian lenders also apply an interest rate buffer—typically adding 2% to 3% above the actual rate—to stress-test your cash flow and ensure your business can handle potential rate increases or market fluctuations.
During the calculation, lenders often adjust your net profit by adding back non-cash expenses, such as depreciation, or one-off interest costs to reflect true trading performance. Depending on whether you apply via full doc or low doc pathways, lenders will verify this cash flow through tax portal records, bank statements, or accountant declarations.
Because serviceability criteria vary significantly across Australian commercial banks and specialist non-bank lenders, policy differences can impact your total borrowing capacity.

- Add-backs are non-cash expenses or one-off costs, such as depreciation or director superannuation, that lenders add back to your net profit to calculate true available cash flow.
- How do ATO tax debts impact loan serviceability?
- Outstanding tax liabilities or active ATO payment plans are treated as existing debts, which reduce your available net cash flow and lower your overall borrowing capacity.
- What is an interest rate serviceability buffer?
- A serviceability buffer is an extra margin added to the actual interest rate by lenders to ensure your business can comfortably manage repayments if interest rates rise.
- Can I prove serviceability with a low doc business loan?
