Refinance calculator
Compare two rates over the same remaining term
Estimate the repayment difference, scheduled cost difference and cash-flow break-even without disguising the result through a longer reset term.
A refinance result is only as useful as its baseline. Compare the same balance, repayment type and remaining term before modelling an intentional change. Include known discharge, break, application, valuation and settlement costs.
The calculator cannot predict future rates, approval, valuation or the final payout and settlement amounts. Obtain current figures before making a decision.
Refinance comparison
Compare staying with switching
Compare the same balance and remaining term at two rates, then test whether an estimated repayment reduction recovers the upfront costs. Check the example balance, term and costs, then enter both rates yourself.
Your scenario
Enter your figures to see an estimate.
Enter the current and proposed interest rates, check the balance, remaining term and upfront switching costs, then select Compare refinance estimates.
The calculator uses the rates you enter. It does not display a lender rate or product offer.
This is a like-for-like cash-flow comparison. It keeps the existing remaining term and treats entered switching costs as paid upfront. A term reset is intentionally excluded because extending a loan can lower repayments while increasing the total amount paid.
General estimate only. This is not credit assistance, a quote, offer, recommendation or approval. It assumes principal-and-interest monthly repayments, a nominal annual rate divided by 12, constant rates and no lender-specific daily-accrual or rounding method. It excludes unentered fees, cashback conditions, offsets, redraw and product differences. Actual costs, savings and eligibility depend on your circumstances and lender assessment.

Use current, comparable inputs
Get the current balance, rate, remaining term and likely switching costs. For the proposed scenario, use documented pricing and fees rather than a headline that may not apply to the requested loan-to-value ratio or purpose.
Interpret repayment cash-flow break-even
Break-even is shown only when the proposed repayment is lower and the entered switching costs are recovered within a lower total scheduled cost over the common term. If you may sell or change the loan earlier, that timing still matters. A positive estimate is not proof that the new loan is suitable.
Review what the calculator cannot price
Offset behaviour, access rules, package changes, approval conditions and future flexibility can matter alongside the estimated dollar result. A broker review can bring those factors into the comparison.
Frequently asked questions
Questions, answered clearly
General answers are a starting point. Your lending options depend on your circumstances.
What costs should I include?
Include known discharge, fixed-rate break, application, valuation, settlement and other switching costs. Also consider changed package fees or lender's mortgage insurance where relevant.
Why should I keep the same remaining term?
It makes the first comparison more like-for-like. Extending the term can reduce repayments but increase how long interest is charged, which can disguise the source of a cash-flow change.
Does a calculated saving mean I will qualify?
No. A refinance is a new application subject to lender assessment, policy and property valuation. The calculator does not assess eligibility.
