When you're juggling home loan repayments, household bills, and long-term savings goals, every dollar counts. That's where a mortgage offset account can be a total game-changer. It may not be the flashiest feature in your home loan, but it could be one of the smartest tools for cutting interest and shaving years off your mortgage.
Let’s dive into how offset accounts work, why they're so popular among Australian homeowners in 2025, and how to tell if one is right for you.
What Is a Mortgage Offset Account?
An offset account is like a regular everyday bank account, but with a twist: it's linked to your home loan. Instead of earning interest like a traditional savings account, the money sitting in your offset account reduces the interest you’re charged on your mortgage.
Say you’ve got a home loan of $600,000 and you keep $50,000 in your offset account. Your lender will calculate interest as if you only owe $550,000. The more cash you park in the account, the less interest you pay.
Unlike making extra repayments, the money in an offset account remains accessible. You can still withdraw it any time you like, which makes it a flexible and effective way to manage your mortgage.
How Does It Work in Practice?
Offset accounts work daily, which means interest on your home loan is calculated each day based on the loan balance minus whatever’s in your offset account. So if you’ve just been paid and that money sits in the account for a few days before bills come out, you’re still saving on interest every single day that balance is high.
Here’s a simple breakdown:
- Loan balance: $400,000
- Offset account balance: $30,000
- Interest charged on: $370,000
Your savings don’t earn interest, but they help you avoid paying it. That’s especially handy in 2025, where interest rates are hovering around 6% or more for many variable-rate loans.
Types of Offset Accounts
There are two main types of offset accounts available in Australia:
100% Offset Account: This is the gold standard. Every cent in your offset account directly reduces the loan balance used to calculate interest. For example, $20,000 in a 100% offset account reduces interest on your mortgage by that full amount.
Partial Offset Account: With this type, only a portion of your balance is counted towards offsetting interest. If your lender offers a 50% partial offset, then $20,000 in the account only reduces your loan interest calculation by $10,000. Still helpful, but less effective than full offset.
Big Wins: Why Offset Accounts Are Worth Considering
Cut Down on Interest
The biggest reason to consider an offset account is the potential to save thousands in interest. Over a 30-year loan, even modest balances in your offset account can make a noticeable difference. For example, consistently keeping $20,000 in your offset over 25 years could save upwards of $70,000 in interest, depending on your rate.
No Tax on Interest Saved
Unlike a high-interest savings account, where you have to pay tax on your earnings, the money you "save" through an offset account isn’t taxed. That’s because you're not technically earning interest—you're just avoiding it.
Flexibility Without Locking Funds Away
Putting extra repayments straight into your home loan can help reduce your balance too, but that money is harder to access. With an offset account, you get the benefit of lower interest while still being able to dip into your funds for emergencies or big expenses.
Helps with Day-to-Day Budgeting
Many Aussies use their offset account as their main transaction account. Your salary goes in, bills go out, and all the while your account balance is helping reduce your mortgage interest. The more money you keep in the account for longer, the more you save.
Is It Always the Best Option?
While offset accounts can be a huge win for many homeowners, they’re not always the most cost-effective solution. Here’s what to watch out for:
Higher Loan Costs
Some home loans with offset accounts come with higher interest rates or additional monthly fees. Compare your potential savings with the costs. A mortgage broker can help with this analysis.
Discipline Is Key
An offset account works best when you maintain a solid balance. If you’re regularly clearing the account, the benefits dwindle. It’s worth using budgeting tools or apps to track spending and maintain a buffer.
Loan Compatibility
Not all home loans come with an offset feature. Some lenders only offer partial offsets or require specific loan structures. Refinancing to a new loan with offset might help if you’re keen to use this feature.
Tips to Maximise Your Offset Account
- Deposit your income directly into the offset account so your balance stays higher for longer.
- Pay bills and expenses on a credit card, then clear it monthly. This gives your offset balance extra time to reduce interest.
- Avoid unnecessary withdrawals. The longer money stays in your offset account, the better it works for you.
- Use budgeting tools to monitor spending and ensure your offset strategy aligns with your goals.
Real Savings in a Changing Market
As interest rates remain a hot topic in 2025, more Aussies are turning to offset accounts as a buffer against higher repayments. Combined with tools like split loans and refinancing, an offset account can be part of a wider mortgage strategy.

Offset and Onward: A Smart Way to Save
A mortgage offset account may not seem groundbreaking at first glance, but its potential to reduce your interest bill and give you flexibility makes it a powerhouse in the world of home loans. It’s one of those quiet achievers—low effort, big savings.
If you're serious about paying off your loan faster, cutting down interest, or simply getting more from your everyday savings, an offset account could be just the ticket.
FAQs
Can I still access money in my offset account?
Yes, your funds are fully accessible, just like a regular bank account. You can use them for everyday spending, bills, or emergencies.
Does an offset account reduce my loan repayments?
Not automatically. Your regular repayment stays the same, but more of it goes toward paying off the principal rather than interest.
Do all lenders offer offset accounts?
No, not all lenders offer them, and some only offer partial offset. Check with your broker or lender before committing.
What’s better: offset account or redraw facility?
Offset accounts give more flexibility as your money is easily accessible. Redraw facilities may restrict how and when you can access extra repayments.
Can an offset account help if I’m on a fixed-rate loan?
It depends. Some fixed-rate loans include offset features, but many don’t. You may need to consider split loan options or switch lenders to access one.
