Offset Account Calculator

An offset account links your savings to your mortgage so interest is only charged on the difference. Enter your average savings balance to see exactly how much interest you save and how many years you cut from your loan. All figures are indicative only.

Loan & Offset Details
An offset account sits alongside your mortgage. Your savings balance is subtracted from your loan balance before interest is calculated — so you only pay interest on the difference. Not all NZ lenders offer offset accounts; ask your adviser which ones do.
