An offset account is often sold as a no-brainer, a way to pay less interest while keeping your money accessible. And for the right person it's genuinely valuable. But its worth depends almost entirely on one thing, how much you actually keep in it. An offset with nothing in it saves nothing. Here's how to work out whether an offset account is worth it for you.
An offset account is a transaction account linked to your home loan, where the balance is offset against your loan when interest is calculated. It can reduce interest while keeping your money accessible, but the benefit depends on your balance, and some accounts charge more for the feature. As at July 2026, an offset tends to be worth it for those who maintain a meaningful balance.
How does an offset account work?
An offset is a everyday transaction account linked to your home loan. The balance sitting in it is subtracted from your loan balance when interest is calculated, so you're charged interest only on the difference. If you owe $400,000 and hold $30,000 in the offset, you're generally charged interest as though you owed $370,000. Crucially, the money stays yours to spend, it isn't paid into the loan, it simply reduces the interest while it sits there.
How much can an offset save you?
The saving scales directly with your balance and how long it stays there. A larger offset balance means a bigger reduction in the interest charged, and because that saving compounds over the life of a long loan, even a steady moderate balance can add up to a meaningful amount. The flip side is that a near-empty offset saves almost nothing. So the value isn't in having the account, it's in what you keep in it.
What's the advantage over extra repayments?
An offset gives you a similar interest-reducing effect to extra repayments, but with a key difference, the money stays accessible. Extra repayments reduce your loan directly but are harder to get back, whereas offset funds can be spent whenever you need them. For people who want to reduce interest without locking their cash away, that flexibility is the whole appeal. It's a way to have the interest saving and keep your emergency buffer at the same time.
When is an offset not worth it?
When you won't keep much in it, or when it costs more than it saves. Some loans charge a higher interest rate or an annual fee for an offset feature, and if your typical balance is small, that extra cost can outweigh the modest interest saving. In that case a simple loan without the feature, or extra repayments, may serve you better. The offset only earns its keep if the saving from your balance beats any premium you pay for it.
What should you check before choosing one?
A few things. Confirm it's a genuine full offset rather than a partial one, since the difference affects how much interest is offset. Compare any higher rate or fee for the feature against the saving your typical balance would generate. And be honest about how much you'll realistically keep in it. Those checks turn the question from a vague yes into a clear answer for your situation.
Frequently asked questions
Is an offset account worth it?
It's worth it when you maintain a meaningful balance, since the interest saving scales with what you keep in the account. It's less worthwhile with a consistently small balance or when the loan charges a higher rate or fee for the feature.
Is an offset better than extra repayments?
They have a similar interest-reducing effect, but an offset keeps your money accessible while extra repayments are harder to reverse. Which suits you depends on how much you value flexibility versus the discipline of paying down the loan.
Do offset accounts cost extra?
Some loans charge a higher interest rate or an annual fee for an offset feature. It's worth comparing that cost against the interest your typical offset balance would save, to check the feature pays for itself.
