Most Australian banks will lend you roughly 5–6 times your gross annual income, but the exact amount depends on your expenses, existing debts, dependants, and the lender's assessment criteria. A person earning $100,000 might borrow $500,000–$600,000; on $150,000, approximately $7

Frequently Asked Questions

Do all banks calculate borrowing power the same way?

No. While all follow APRA guidelines (including the 3% buffer), banks differ in how they assess income (especially bonuses, overtime, and rental income), which expense benchmarks they use, and their internal risk appetite. This is why a broker can help — they know which lenders are more generous for your situation.

How does the APRA buffer work?

APRA requires banks to test your ability to repay at the loan's product rate plus a 3% buffer. If the rate is 6.22%, the bank assesses you at 9.52%. This ensures you can still afford repayments if rates rise.

Can I borrow more with a joint application?

Yes. Two incomes significantly increase borrowing power because expenses don't double (HEM for a couple is roughly 1.4x a single person). Two people earning $80,000 each can typically borrow 30–50% more than one person earning $160,000.
