Indicative only. Lenders assess your repayments at your rate plus a 3% serviceability buffer (APRA guidance), and apply their own income, expense and policy rules. Your actual limit will differ. Income is converted to net using the 2026-27 resident tax scale plus 2% Medicare, no offsets — see the methodology.

Common questions

How do lenders work out how much I can borrow?
They take your income, subtract tax, living expenses and other debt repayments, then check the surplus can service the loan at an assessment rate — your rate plus a 3% serviceability buffer under APRA guidance. On the example figures, that supports about $633,000.
Why is the assessed rate higher than my actual rate?
The 3% buffer is a stress test: lenders check you could still pay if rates rose. It is why your borrowing limit is lower than your current repayment might suggest.
Is this an approval?
No. It is an indication only. Lenders apply their own income, expense, credit and policy rules, and count some income types differently. Treat it as a starting estimate.
