How to use our Mortgage Refinance Calculator

Our Mortgage Refinance Calculator helps you estimate the financial pros and cons of refinancing a home loan in Australia by comparing your current mortgage against a proposed new loan. It factors in interest rate differences, remaining term, ongoing fees, exit or break costs, new lender establishment costs, cashback incentives, and any extra amount borrowed. This matters because a lower rate does not always mean a better outcome once upfront costs and loan term changes are included.

How to complete the calculator for the most accurate result:

1. Current mortgage details

Enter your current loan balance, current interest rate, and the remaining term in years and extra months. Choose your repayment frequency. If you know your current regular repayment, add it (optional); otherwise the calculator will estimate it. Include any extra repayments per period and your current monthly loan or package fee. Add your estimated discharge, exit, or fixed-rate break fee, as this can materially change the break-even point.

2. Proposed refinance details

Enter the new interest rate, select the new rate type, and input the new loan term. Add any extra repayment you plan to make on the new loan to reflect faster debt reduction.

3. Refinance costs and adjustments

Enter application, settlement, legal, valuation, lender and government fees. Add any cashback incentive, and include any extra amount borrowed or cash out. If you will pay some costs from savings instead of adding them to the loan, enter the amount under costs paid upfront. Include the new monthly loan or package fee and choose your main refinance goal.

How to interpret the results:

Review the estimated monthly repayment difference, lifetime saving or cost difference, and interest saving or increase. The break-even point shows when cumulative savings offset net refinance costs after cashback. Use the charts and amortisation comparison table to see how balances, interest and total costs evolve over time.

Important: This calculator provides general information only and does not consider your objectives, financial situation or needs. Results are estimates and may differ due to lender policies, rate changes and fees. Consider getting professional advice before refinancing.
