Rate headline is not enough
A cheaper advertised rate is only useful if the saving survives fees, feature trade-offs, and realistic cashflow assumptions.
Break-even mindset
Estimate the monthly difference first, then ask whether the switching effort, discharge costs, and package costs still make sense.
Stress before switching
Refinancing should improve resilience, not just today's number. Pressure-test the loan under higher rates before you commit.
Refinance path after the savings estimate
Use this order when the refinance estimate looks interesting and you need to decide whether the switch is still worth pursuing.
1. Pressure-test repayments
Make sure the new rate path still looks strong under less friendly scenarios.
2. Compare quote quality
Move beyond headline savings into fees, execution certainty, and feature fit.
3. Check offset value
Confirm whether package features and account structure improve the real outcome.
4. Compare with self-acceleration
See whether extra repayments on the current loan compete with the refinance case.
Savings first, then discipline
A refinance estimate is useful only when the new path still works under stress.
Use this page to decide whether the opportunity is worth deeper comparison, not to skip the comparison.

FAQs
What does this refinance calculator estimate?
It estimates the repayment difference between your current rate and a possible new rate using your remaining balance and term.
Does a lower rate always mean I should refinance?
No. Fees, features, cashflow resilience, and execution risk still matter. Use the result as a first filter, not a final answer.
What should I do after the savings estimate?
Stress-test the repayment range, then compare quote quality and feature fit before changing lenders.
