Home Loan Repayment Calculator

Home loan calculator

Use this calculator to estimate mortgage repayment figures, how much you may afford to borrow, and how much time and money you could save by making extra home loan payments.

You might be surprised to discover how every little bit counts. On the average mortgage, paying just an extra $20 a week could save you more than $25,000 in interest costs over the life of your loan.

There’s no better motivation to pay down your mortgage faster than seeing the thousands of dollars you could save and years you could cut off your home loan by making a few simple changes to your budget.

Want to know more about budgeting and how to own your own home sooner? You’ll find loads of handy tips in our Money Tools section.

We can also provide a free consultation including a 12-month budget forecast to help you better manage your money.
