What are extra home loan repayments?

Most, if not all, variable home loans let you make extra repayments against your mortgage principal – usually for free. These extra repayments count towards the initial loan amount you borrowed, thus eliminating your debt faster. 

This also reduces your interest payments over time, since the principal used to calculate your interest gets smaller, faster.

How to make extra repayments on a home loan

If your home loan lets you make extra repayments, it’s usually just a matter of increasing the size of your mortgage repayments. For example, instead of transferring $2,000 a month into your mortgage account, you transfer $2,050. 

You could also transfer a lump sum payment the same way, i.e. putting your tax return or a work bonus toward your mortgage.

What happens if I pay an extra $100 a month on my home loan principal?

How much money extra repayments save you depends on your initial loan amount, loan term, and interest rate. But let’s take a look at some home loan statistics to make an estimate. 

The average mortgage size in Australia is $610,000, and the average variable home loan interest rate in Mozo’s database is 6.85% p.a. (for owner-occupiers with LVRs < 80%) as of January 2024. Let’s say you have a loan term of 25 years.

According to Mozo’s extra repayment calculator, paying an extra $100 monthly on this home loan for the first ten years could save $34,484 in total interest and discharge the mortgage 10 months early. Not too bad!

What is a home loan redraw facility?

A home loan redraw facility is a special account attached to your home loan that lets you dip back into extra repayments you’ve already made. 

Pulling funds from a redraw can sometimes come with fees. It will also increase your loan size since you’ve pulled the funds from your mortgage, thus increasing your interest payments.

Can you make extra repayments on a fixed home loan?

Extra repayments are a standard feature for variable home loans, not fixed ones. It’s unlikely you make extra repayments during your fixed home loan term
