Estimate how much you could borrow
About this calculator
Lenders take your after-tax income, subtract living expenses and existing repayments, then test whether you can still afford the loan at your rate plus about a 3% buffer. This tool applies that logic to give a deliberately conservative borrowing estimate.
Frequently asked
Why add 3% to the rate?
It's the serviceability buffer required by the regulator, to check you could still afford repayments if rates rose. So the assessment rate is typically about 3% above the rate you'd actually get.
Will I really be able to borrow this much?
It's indicative. Real approval also depends on credit history, employment type, the HEM living-expense benchmark and each lender's policy.
