A transparent, editable estimate of your indicative borrowing power and home-loan repayments, built on a clearly-shown assessment model. No jargon, no sign-up to get started.
These default to a conservative, HEM-style model. Editing them changes the estimate live. They are illustrative assumptions, not any single lender’s actual policy.

Your borrowing power is the maximum a lender is likely to lend you, based on your income, living expenses, existing debts and the serviceability buffer lenders must apply. This calculator gives you an indicative figure and estimated repayments, so you can set a realistic budget before you start house-hunting or talk to a lender.
Every lender assesses serviceability differently, so treat the result as a guide, not a pre-approval.
Lenders look at your income, living expenses, existing debts and commitments, then apply a serviceability buffer — an interest-rate margin above the actual rate — to check you could still repay if rates rose. What's left over sets the maximum loan.
Each lender uses its own assessment rate, expense benchmarks (such as the HEM), and treatment of things like HECS-HELP, casual income and existing credit limits, so the same borrower can get materially different answers.
No. It's an indicative estimate only — nothing is submitted to a lender and there's no credit check.
General information only. This is not credit assistance, a credit quote or an offer of finance, and the figures are indicative estimates — confirm with a lender before you rely on them.
