Why this calculator exists

Sana Hosseini built this free, comprehensive mortgage repayment calculator to make complex Australian home-loan comparisons easier to understand. Instead of showing only one repayment figure, the multi-scenario mortgage calculator lets you explore up to nine structures and see how different assumptions may affect repayments, interest, fees, and the estimated loan term.

It is designed for Australians who want a practical starting point before speaking with a lender, mortgage broker, financial adviser, accountant, or other qualified professional.

What you can compare

• Up to nine mortgage scenarios side by side.
• Principal and interest or interest-only repayments.
• Monthly, fortnightly, and weekly repayment frequencies.
• Offset account, extra repayments, lump sum, and ongoing-fee modelling.
• Introductory or fixed-rate periods followed by another rate.
• Estimated repayments, total interest, fees, savings, balances over time, interactive graphs, full repayment schedules, and PDF reports.

Our approach

We aim to present calculations in plain language, make assumptions visible, and give users control over the values used in each scenario. The calculator does not promote a particular lender or home-loan product.

We also aim to keep the website accessible, responsive, and useful across desktop, tablet, and mobile devices.
