How to use Australian bank home loan calculators

Find out how to calculate your borrowing power with these home loan calculators from the big four banks.

Before you apply for a home loan, it’s essential to work out how much you can reasonably afford to borrow and then repay. Your income, assets, employment status and the purchase price of the property all have a bearing on your ability to service a loan, so you need to be sure of your repayment capabilities before you take out a mortgage.

That’s where home loan calculators come in. These simple-to-use online tools help you work out the size of the loan you can afford to take out, and how much your ongoing repayments will be. Let’s take a look at the home loan calculators offered by the Big Four banks and how to use them.
