Borrowing power estimator
How much could you borrow?
This estimator works the way lenders do: net income, minus living costs and commitments, tested at your rate plus a 3% buffer. It's an estimate only — real capacity varies significantly between lenders.

How this estimate is calculated
- Gross income is converted to take-home pay using current resident tax rates and the Medicare levy.
- Living costs are the higher of what you enter and a household expense benchmark similar to the HEM figure lenders use, which rises with household size, dependants and income.
- Other loan repayments are deducted, and credit cards are counted at 3% of the total limit per month — whether or not you use them.
- What’s left each month is tested at your interest rate plus a 3% serviceability buffer over 30 years. The loan that surplus could repay is your upper estimate; the conservative figure is 15% lower, to allow for stricter lenders.
Lenders also treat rental, bonus, overtime and self-employed income differently, and some use lower buffers or longer terms — which is why the same person can get quite different answers from different banks.
This calculator provides an estimate only, based on the figures you enter and simplified assumptions. It is not an offer of credit, a quote, or financial or credit advice, and it does not take your personal circumstances into account. Lender assessment criteria differ and change. Speak with us for an assessment based on your actual situation. Any interest rates shown are examples only and subject to change. A comparison rate is calculated on a loan of $150,000 over 25 years. WARNING: This comparison rate is true only for the examples given and may not include all fees and charges. Different amounts and terms will result in different comparison rates. Costs such as redraw fees or early repayment fees, and cost savings such as fee waivers, are not included in the comparison rate but may influence the cost of the loan.

The spread between lenders can exceed $200,000
Same income, same expenses — very different answers depending on the lender. Finding the right end of that spread is literally our job.
