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.
