Worried your home loan rate isn’t competitive? Maybe it's time to switch

Yes, the RBA has increased the cash rate by 0.25% and banks are already responding by passing on the rate hike to variable home loans.

So now might be the best time to look at your current mortgage interest rate to double-check that you’re getting a competitive rate. But before you think about switching there are a few things to consider:

  • Extra fees and costs that may come with refinancing home loans
  • Ensuring a switch gets you a better deal.

Below we’ve created a scenario where a couple is comparing their current home loan with a major bank to a smaller lender.

Major bank vs smaller lender

Jacob and Thomas bought a house in a suburb near a major city for $800,000. After paying with a 20% deposit the couple got a variable home loan from CommBank for 4.80% p.a. for 25 years.


Cost of the house (minus deposit)$640,000
Variable interest rate4.80% p.a.
Monthly repayment$3,677
Total interest expected to pay$460,154

*This total does not include council fees, bills or home insurance costs.

Jacob and Thomas’ monthly mortgage repayment is $3,677. Which is about $44,124 annually.

After a while, the couple felt the rate they had wasn’t competitive enough, especially when more rate hikes loom. So they decided to see how much they could be saving by switching to an online lender instead. 

If they were to switch to a smaller lender like Athena then they might get a variable interest rate of 2.24% p.a. which is 255 basis points (or 2.55%) lower than CommBank’s rate.

Variable interest rate2.24% p.a.
Monthly repayment$2,788*
Total interest expected to pay$196,420

*This total does not include council fees, bills or home insurance costs.

By switching to Athena, Jacob and Thomas were able to slash $889 from their monthly repayments and pay about $33,456 annually. Not only that, the total interest payable is reduced by $263,734, which means that they can pay off their home faster.

The average variable interest rate is 3.02%, which means that if the couple secures that 2.24% rate they are 78 basis points below the average.

But what happens if they can’t get the low 2.24% rate? What if they get something closer to the average?

Monthly repayment$3,042*
Total interest expected to pay$272,484

By finding a rate closer to the average, Jacob and Thomas could potentially save $635 on their monthly repayments. Paying about $36,504 annually compared to the $44,124 annually with their current rate with CommBank. Even the average rate provides them with a better outcome!

After some thought, the couple decided to make the switch and put the money saved into a term deposit with a high interest rate.

Should I switch my home loan?

woman wondering what home loan to pick

One of the key features of switching your loan from one lender to another is to find a better deal to save money in the long run. That’s why thousands of Australians refinance their home loans.

An Australian Bureau of Statistics report found that Australians are financing at about $14 billion a month!

To get started you should research, research, research!

You want to make sure you’re getting the best deal possible with a home loan that suits all your needs. It’s also important to see what the requirements of each lender are. Some require you to have a certain amount of equity before you can switch or get lower rates. The more equity you have, the higher chance you have of nabbing a cheaper mortgage.

If you’re still not sure about how to refinance your home loan don’t worry, we have plenty of guides available to help you.
