Mortgage repayment calculator FAQs

We know mortgage finances can seem pretty complicated, so we've listed the questions we hear all of the time.

How can I save on my mortgage payments?

You can save the amount of interest you'll pay on your mortgage by shortening your mortgage term.

You can also reduce the amount of interest you'll pay by overpaying on your mortgage.

To lower your monthly mortgage repayments, you can increase the length of your mortgage term. Doing this is likely to mean you'll pay more interest to your lender in the long term, but it can help to make your monthly mortgage repayments more manageable.

Is the result from the calculator accurate?

Our Mortgage Repayment Calculator provides a good indication as to what your monthly mortgage repayments could be.

The tool uses your home's estimated value, your mortgage amount, the mortgage interest rate and the length of your mortgage term to calculate your mortgage repayments.

You can use our tool to see how changing interest rates and altering the length of your mortgage term could affect your monthly mortgage repayments.

Once you have a specific mortgage deal in mind, the precise monthly mortgage repayments can be provided to you by your mortgage broker or lender.

Can the calculator estimate payments for different loan terms?

Yes it can. Simply put in the amount and term of your mortgage and we'll take care of the rest.
