What is Borrowing Power?
Borrowing power is the maximum amount a bank will lend you for a home loan, based on your income, expenses, debts, and the lender's assessment criteria.
How this calculator works
Australian banks assess your capacity to repay using a serviceability buffer — typically the loan rate plus 3%. This means if the actual rate is 6.5%, they test whether you can afford repayments at 9.5%. The calculator estimates your maximum loan based on 30% of gross income allocated to repayments, minus existing debt commitments and living expenses. It then shows the maximum property price at different deposit levels (20%, 10%, 5%) and your debt-to-income ratio — a key metric banks use to assess risk.
