Borrowing Calculator – Estimate Your Home Loan Borrowing Power

Our Borrowing Calculator helps Australian home buyers quickly estimate how much they may be able to borrow — based on real-world lending principles used by banks and lenders across Australia.

Whether you’re a first home buyer, upgrading, refinancing, or investing, understanding your borrowing power is the first step before searching for property. This tool gives you a realistic estimate in under two minutes, without affecting your credit score.

Why Borrowing Power Matters

Many buyers look at property prices before understanding their borrowing capacity. This can lead to unrealistic expectations or financial stress. By calculating your borrowing power early, you gain clarity and confidence before speaking to agents or making offers.

This tool provides estimates only and does not replace professional advice. Actual borrowing capacity will vary based on lender policy, credit assessment, and individual circumstances.
