Rate rise repayment calculator
A 0.25% rate rise on a $600,000 interest-only loan adds about $29 a week to your repayments, and a 1% rise adds about $115. Enter your own loan to see the extra cost each week, month and year, and the weekly rent that would cover it on an investment property.

Test every loan at onceHow a rate rise changes your repayments
On an interest-only loan the repayment is just the balance times the rate, so every 0.25% rise costs the same: the balance × 0.25% a year. A principal and interest loan gets re-worked over the years you have left, and because part of each repayment is already paying the loan down, the rise is a bit smaller in dollars. More of each payment goes to interest, though, so the balance comes down more slowly.
On an investment property the question that matters is how much more rent would cover it, which is the extra weekly repayment. The chart marks two points: the rise where your rent stops covering the loan, and the rise where it stops covering the loan plus your other costs.
