Borrowing power calculator

Enter your income, living expenses and what you already owe, and see the loan size a lender is likely to approve. The model works the way a bank’s serviceability check does: income after tax and HECS, rental income shaded, and every dollar of repayment tested at your rate plus a 3% buffer. Free, and no account needed.

Enter your monthly living expenses to see an estimate. There’s no default figure, because guessing this one shifts the result by tens of thousands.

How the estimate is built

Lenders don’t lend against your gross salary. They start from what’s left after income tax, the Medicare levy, any HECS repayment and the low-income offset, discount rental and other income, then subtract your declared living expenses and the repayments on every existing loan and credit card limit. Whatever is left each month is your surplus, and the maximum loan is the amount that surplus can service over the term at the assessment rate.

The assessment rate is the part most people haven’t met. APRA requires lenders to test you at your actual rate plus a 3 percentage point buffer, or at a floor rate if that’s higher, which is why a 6.2% loan is assessed at 9.2%. The calculator also shows a downside figure with your declared expenses lifted by 20%, because expenses are the input people most often understate and the one that moves the answer most.

FAQ

Questions worth asking first

Because guessing it moves the result by tens of thousands of dollars. Lenders benchmark expenses against household surveys and take the higher of that or what you declare; this calculator takes what you declare and nothing else, so it can't produce a figure until you've entered one.

This calculator provides indicative serviceability estimates only and does not constitute financial or credit advice, a credit assessment, or a loan offer. It applies your declared expenses with no benchmark floor, ignores lender policy, credit history, and lender's mortgage insurance, and each lender sets its own buffer and floor rate. Confirm your borrowing position with a licensed mortgage broker or credit adviser before you apply.
