Mortgage Repayment Calculator

Use our mortgage repayment calculator as a guide to what your repayments could be on your new home loan.

What will the repayments be on my mortgage?

Our mortgage repayment calculator gives you an estimate of what your repayments could be, based on your home loan amount, your loan type and the interest rate you think you'll be paying.

Once you get an idea of your mortgage repayments from the calculator, together with the rest of your budget you'll start to see whether you can realistically afford the home you want to buy, you might even discover you can afford a more expensive one than you first thought.
