Owning a home is one of life’s biggest financial commitments, and for most Australians, it means decades of mortgage repayments. But did you know that there are smart ways to reduce the interest you pay and potentially save thousands over the life of your loan? With a little know-how and strategy, you can fast-track your journey to a debt-free home.
What Is Home Loan Interest and Why It Matters
Home loan interest is the cost you pay your lender for borrowing money. Even a small difference in interest rates can add up to tens of thousands of dollars over the life of a loan. For example, a 30-year mortgage on a $600,000 home could cost over $300,000 in interest alone, depending on the rate.
So it’s worth finding ways to reduce that cost as much as possible.
Refinance Your Home Loan to a Better Rate
One of the most straightforward ways to lower your mortgage interest is through a home loan refinance. This means switching your current loan to a new one—either with your existing lender or a new provider—that offers better terms.
Many Australians refinance to:
- Secure a lower interest rate
- Reduce monthly repayments
- Access equity for renovations or investment
- Shorten the loan term
Before refinancing, make sure to factor in the associated costs such as break fees, application charges, and legal fees. In many cases, the long-term savings still make refinancing a worthwhile move.
Make Fortnightly Instead of Monthly Repayments
Most lenders allow you to choose between monthly and fortnightly repayments. By paying half your monthly repayment every two weeks, you end up making 26 payments a year instead of 12. That’s the equivalent of one extra full repayment annually, which can shave years off your loan term and save you a significant amount in interest.
Use an Offset Account
An offset account is a transaction account linked to your mortgage. The money in this account reduces the amount of your loan used to calculate interest. For example, if you have a $400,000 loan and $40,000 in your offset account, interest is only charged on $360,000. Keeping your savings or salary in an offset account is a simple and effective way to lower the interest on your loan without making extra repayments.
Round Up Your Repayments
Another easy trick is rounding up your regular repayments. If your scheduled payment is $1,430 per month, consider rounding it up to $1,500. That extra $70 each month directly reduces your principal, which in turn lowers the interest you’re charged. Small additional payments made consistently can make a big difference over time.
Make Extra Lump Sum Payments
If you receive a bonus, tax return, or inheritance, consider putting it towards your mortgage. Even occasional lump sum payments can significantly reduce the balance of your loan and help you reach your financial goals faster. Check with your lender first to ensure your loan allows extra payments without penalty.
Reduce Your Loan Term
When you refinance your home loan, you may be tempted to extend the term to reduce monthly repayments. But doing so increases the total interest paid. Instead, consider refinancing to a shorter loan term. While your repayments may be higher, you’ll pay off your home faster and save on interest in the long run.
Review Your Loan Regularly
Many homeowners set and forget their mortgage. But interest rates and lending products change frequently. Reviewing your home loan every one to two years can ensure you’re still getting a competitive rate. If you find a better deal, don’t hesitate to explore your options, including a home loan refinance.
Avoid Interest-Only Loans (Unless Strategically Used)
Interest-only loans may seem attractive because of their lower initial payments, but they don’t reduce the principal during the interest-only period. This means you’ll pay more interest in the long term. They can be useful in certain investment scenarios but are not ideal for most homeowners looking to own their property sooner.
Compare Lenders, Not Just Rates
The lowest rate isn’t always the best deal. Look at comparison rates, which factor in fees and other charges. Also consider the flexibility of the loan, such as the ability to make extra payments or access redraw facilities.
A well-structured loan from a reliable lender will serve you better than one that looks cheap but comes with hidden costs.
Paying off your home loan sooner doesn’t have to mean sacrificing your lifestyle. With the right strategies—like switching to fortnightly repayments, using an offset account, or taking advantage of a home loan refinance—you can save thousands in interest and gain peace of mind knowing you’re financially ahead.
The key is to stay proactive. Don’t wait for your lender to offer you a better deal—shop around, ask questions, and take charge of your mortgage. Every dollar saved in interest is a dollar you can invest in your future.
