Mortgage Calculators

The more you know, the less you stress

Crunching the numbers to make it work.

Whether you need a mortgage calculator to work out your borrowing power, loan repayments or some help budgeting to work out what you can afford, you’ll find them here. Start with the budget planner, then assess your borrowing power and finally work out what your mortgage repayments would be.

Budget Planner

Budgeting is the best way to steer your finances, stay in control and prepare for managing your mortgage.

Why use a mortgage calculator?

Even if you’re a finance whizz, using a mortgage calculator saves time and ensures a higher degree of accuracy.

Mortgage calculators help you to understand how much a mortgage really costs, including total interest paid over the loan’s term. You can use them to calculate repayment amounts, which can be applied to your budget. And you can also use them to experiment with numbers by varying loan amounts, interest rates and loan terms. It’s always enlightening to try out ‘what if’ scenarios by increasing repayment amounts or reducing terms.

What could impact my repayments?

If you’re thinking about having all or some of your mortgage on a floating interest rate, your repayments will be affected by ups and downs in the OCR (official cash rate).

A mortgage calculator can let you see how these interest rate moves could impact your repayments.

It’s always good to be prepared for worst-case scenarios, like a significant interest rate hike that pushes your repayments up. You can also see what happens with a best-case scenario, where rates drop, causing a reduction in repayments.
