NZ Loan Calculator 2026

The calculator applies the interest rate you enter to the amount borrowed. A lender's figure also includes establishment and administration fees, and possibly insurance sold alongside the loan. Compare offers on the total amount repayable rather than on the monthly figure.

A fixed rate holds your repayment steady for the fixed term, which makes budgeting predictable but usually limits extra repayments or charges a break fee to exit early. A floating rate moves with the market and normally allows unlimited lump-sum repayments. This calculator assumes one constant rate throughout.

A shorter term raises the monthly payment but cuts total interest sharply, because interest is charged on the outstanding balance every period. Run the same loan over several terms and compare the total interest column — the difference is often far larger than people expect.

On most New Zealand loans an extra repayment reduces the principal, so the payment stays the same and the loan finishes earlier. Because every later month is then charged interest on a smaller balance, even modest regular overpayments compound into a meaningful saving.

No. A lower payment usually means a longer term, and a longer term means more total interest even at the same rate. The monthly figure tells you whether a loan is affordable; the total repayable tells you what it costs.
