Which mortgage term has been best?

Should you fix for 1 year, 2 years or 5? Nobody knows where rates are heading, but we do know where they’ve been. This calculator replays your loan through every month of real New Zealand mortgage rates since 2005 and shows what each fixing strategy would actually have cost you.

Choose standard or special rates, then enter your loan details and a start date. Further down, it runs your loan through every 5, 10 or 15 year stretch in the data to show which strategies have tended to come out ahead, and by how much. Rates are updated monthly from Reserve Bank of New Zealand data.
