Calculate your home loan borrowing power.

The calculator uses a standard serviceability model – it applies a gross-to-net income conversion, deducts declared expenses and debts, and calculates the loan amount that can be serviced at the assessment rate over your chosen term. It gives a useful starting range, but it does not replicate any individual lender’s full credit policy. Think of it as a compass, not a map.

No. This calculator runs entirely in your browser and does not submit any data to credit bureaus or lenders. Your credit score is only affected when a lender makes a formal credit enquiry as part of a loan application.

It is not as accurate as it is for a PAYG applicant. Self-employed borrowers face a more complex income assessment — lenders typically average the last two years of taxable income from tax returns, which may not reflect your current earnings. Some lenders offer low doc home loan options that use alternative verification. Our self-employed home loans page explains how this works, and a broker assessment will give you a far more accurate picture than a general calculator can.

Lenders Mortgage Insurance (LMI) is a one-off cost charged when you borrow more than 80% of the property’s value. It protects the lender — not you — in the event of a default. On a $700,000 purchase with a 5% deposit, LMI can add $25,000 to $30,000 to your loan. First home buyers may be able to avoid LMI entirely through the First Home Guarantee, which allows a 5% deposit with no LMI for eligible buyers.
