Don’t set and forget your mortgage; instead, follow these smart strategies to make your money work for you.

  • Checking in on your home loan each year is key to achieving your financial goals, according to CommBank home lending executive Eva Ie.
  • Learn smart strategies that will make your money work harder, from leveraging offset accounts to consolidating your debt and taking advantage of technology.

When was the last time you looked at your mortgage? For many of us, it’s in the too-hard basket. However, according to CommBank home lending executive Eva Ie, checking in on your home loan each year is key to achieving your financial goals. “Your income or financial situation may change and this helps make sure you’re still on track with your repayments,” she says. So, rather than going with a set-and-forget mindset, Ie says these are the smart strategies that will make your money work harder.

1. Leverage the power of your offset account 

One of the easiest ways to lower the amount of interest you pay on a mortgage is to have an offset account. This is a transaction account linked to your mortgage. “Every day we look at how much you owe us and how much you’ve got in your offset account and then we calculate the interest on the difference,” says Ie. “Let’s say you owe $500,000 and you have $50,000 in your offset account—you’ll only be charged interest on $450,000.” 

Think it’s not worth putting your income into the offset because you spend it anyway? Think again. Interest is calculated daily so it can still have an impact. “You don’t use all the money straight away and every day it’s in there makes a difference,” says Ie. 

Eligible CommBank home loans allow multiple offset accounts, which means you can set up your money in a way that works for you. “Some people like to separate their money into accounts for transactions, bills, holiday savings and their kids—all of these can be linked to the mortgage so every dollar you have is offsetting the home loan,” she says. “Don’t underestimate the power of offset.”  

2. Chat to your lender

There are plenty of reasons to refinance your home loan but the most common one is to get a lower interest rate, reducing how much you pay in the long run. A good place to start: chat to your lender to find the best fit for you. Are you getting the best rate for the services being offered? What loan features do you really need? Some digital-only loans, for example, offer fewer features but may have lower rates. 

Perhaps you need help with cost of living pressures. “If you’re struggling and can’t keep up with repayments, consider refinancing to extend your loan term,” says Ie. “Even though it’ll take longer to pay off, at least it gives you some relief.” 

There’s also a misconception that refinancing your home is hard to do. “Refinancing is actually easy—it can be completed within days if it’s a straightforward application.”

 “I have my money in my bank account, working hard for me to offset the loan and I only pay off my credit card balance when it's due,” says Ie. “I pay the full balance with autopay so I will never pay credit card interest and my money is always in my account to help me save home loan interest until the last day I need to pay my credit card.”  

3. Make extra payments

Got a tax refund? Given a bonus at work? Consider making an extra payment off your loan. Putting additional money on your home loan is a good way to reduce the length of your loan as you’ll bring down the net total and pay less interest over the term. 

The trick here is to see it as a one-off payment and resist the urge to tinker with your loan at the same time. “Most banks give you the flexibility to draw back your extra repayment if you don’t reduce your monthly commitment,” says Ie. “Just keep the same repayment every month.”

4. Consolidate your debt

Managing debt so you’re paying the lowest possible interest rates across the total of your debts just makes financial sense. “Interest on a credit card is normally about 20 per cent,” says Ie. “A basic variable home loan interest rate [in December 2024], on the other hand, is about 6.4 per cent. That’s a difference of nearly 14 per cent interest.” Don’t think of this as a “get out of debt free” option, though: “Try to make the same repayment off the credit card component as you do to the home loan so you’re not paying off the credit card over 30 years.”  

Tip: Use tech to stay up to date 

Punching your numbers into the CommBank Mortgage Repayment Calculator is a quick way to make sure your money works hard. “A mortgage calculator can help you budget,” says Ie. “You may say, ‘If I want to pay my loan off in 15 years, what will my repayments look like?’ Jump on every now and again to check you’re still on track.”
