Mortgage Refinance Solutions Home Loan Repayment Calculator

Our Home Loan Repayment Calculator helps you estimate your mortgage repayments in Australia and understand how a loan may reduce over time. It is useful for budgeting, comparing loan terms, and visualising an amortisation schedule (how each repayment is split between interest and principal). The calculator is designed for planning only and works best when you enter realistic assumptions.

Important information: Results are estimates only and do not constitute a quote. Interest rates and loan features vary by lender and may change. This information is general and does not take into account your objectives, financial situation or needs. Consider whether it is appropriate for you and seek professional advice if required.

How to complete the calculator fields (in order):

1. Purchase Price: Enter the property purchase price. If you expect to borrow extra for costs, you may choose to include amounts such as stamp duty, insurance, and other buying costs in this figure so your estimate reflects your likely loan size. Enter whole numbers only (no dots or commas).

2. Deposit or Equity Value: Enter your cash deposit or usable equity from another property (if applicable). A higher deposit generally reduces the loan amount and can lower repayments. Enter whole numbers only (no dots or commas).

3. Term of Loan (years): Select the number of years to repay the loan. Longer terms usually reduce repayments but increase total interest paid over the life of the loan.

4. Interest Rate (% per annum): Select an interest rate for the simulation. Use a realistic rate and consider testing higher rates to understand “rate rise” risk.

5. Calculate: Click calculate to generate your results.

How to interpret the results:

1. Repayment estimate: Use this as a starting point for affordability checks, remembering real loans may include fees and different features.

2. Amortisation charts: Review the loan balance chart to see how your balance falls over time, and the interest versus principal chart to understand how early repayments are typically interest-heavy, then shift toward principal reduction later.

3. Compare scenarios: Adjust the term, deposit/equity, or interest rate and recalculate to compare loan terms and see how changes affect repayments and total interest over time.
