About this calculator

Assumes your offset balance stays roughly constant for the life of the loan, the contracted repayment is unchanged, and the interest rate is constant. In practice an offset balance fluctuates as you spend and save — treat the result as an upper bound for a balance you can comfortably keep parked. Some loans charge a higher rate or monthly fee for offset features; weigh that against the savings shown here. Talk to a licensed mortgage broker before relying on a figure.
