Estimate early repayment costs for breaking your fixed-rate mortgage

What is a break fee?
When you break a fixed-rate mortgage early (by refinancing, selling, or paying off), banks charge a fee to cover their loss of interest. This is also called an "early repayment cost" or "prepayment penalty."

Disclaimer: Break fee calculations are complex and vary significantly between lenders. Each bank uses its own formula, and may include wholesale rate adjustments, administrative fees, and other factors. This calculator provides a simplified estimate based on interest rate differentials. Always obtain an official break fee quote from your bank before proceeding with refinancing or early repayment.

When Do Break Fees Apply?

Good news: Most NZ banks allow 5-20% extra repayments per year without break fees. Check your mortgage terms for your specific allowance.
