How Much Can I Borrow on an $80k Salary in Australia?
Updated 2 September 2026 · 5 min read
Quick answer: there is no reliable lender-wide borrowing figure for an $80,000 salary. Your result can change materially with household expenses, dependants, credit limits, other debts, loan type and the lender's current assessment settings. Use a calculator for a transparent scenario, then confirm it with a lender or broker.
What changes the result
- Income after tax: a lender may treat overtime, bonuses, allowances and a second job differently from base income.
- Household costs: lenders use their own expense benchmarks and can use the higher of your declared costs or their internal assessment. BorrowPower uses a transparent expense floor, not a lender's HEM figure.
- Existing commitments: car finance, personal loans, BNPL and even unused credit-card limits can reduce serviceability.
- Assessment rate: lenders test whether repayments remain affordable above the product rate. APRA's mortgage-lending standard requires a 3 percentage-point serviceability buffer for ADIs.
How to test an $80k scenario
Start with your base salary and actual regular expenses. Add every recurring debt payment and the full limit of each credit card. If you expect a change such as a child, a car loan or a reduced work week, run that as a separate scenario rather than assuming today's result will hold.
- Run a baseline with your current expenses and no optimistic income assumptions.
- Run a cautious version with higher household costs or a future debt payment.
- Use the repayment estimator to check whether a loan amount still feels manageable at a higher rate.
Before you rely on an estimate
- Keep the purchase deposit separate from duty, conveyancing and other buying costs.
- Reduce or close unused credit limits only where that makes sense for you.
- Ask a lender how it treats your income type, debts and household expenses.
- Do not treat an online result as a pre-approval or a property budget on its own.
Use the Borrowing Power Calculator with your own inputs, then estimate repayments and plan your deposit and buying costs.
