# Offset account hacks to pay off your home loan faster

**In short:** An offset account reduces the loan balance your interest is calculated on, every day, without locking your money away. The most effective habits are having your salary paid into it, running everyday spending through a credit card paid in full each month, keeping your emergency fund and lump sums there, and never confusing it with redraw. Done well, an offset can cut years off a 30-year loan.

Offset accounts are the most useful feature on an Australian home loan and the most under-used. Most people have one, put a bit of money in it, and forget it. This post explains the mechanics briefly and then gives you the practical habits that turn an offset from a nice-to-have into the thing that gets you out of debt years early.

## How an offset works in one paragraph

Your lender calculates interest daily on your loan balance minus the balance in your linked offset account, then charges it monthly. Money in the offset earns no interest itself, but it reduces the interest you pay at your loan rate, tax-free, and you can withdraw it any time. Because your repayment stays the same, the interest saved goes towards principal, which is what shortens the loan. The [offset calculator](/calculators/offset/) shows the effect for your numbers.

## The maths that makes it worth the effort

For illustration, a $600,000 loan at 6.00% p.a. over 30 years, principal and interest, repayment $3,597 a month.

| Strategy | Interest saved over the loan | Time cut from the loan |
|---|---|---|
| $30,000 kept in offset from day one | Around $130,000 | About 3 years 8 months |
| Extra $200 a month repaid instead | Around $106,000 | About 3 years 11 months |
| Both together | More than either alone | More than either alone |

An offset balance you never touch behaves like an extra repayment you can take back. That flexibility is the whole point. Compare it with the [extra repayments calculator](/calculators/extra-repayments/).

### Why an offset beats a savings account

Interest earned in a savings account is taxed at your marginal rate. Interest saved in an offset is not taxed at all. For someone in the $45,001 to $135,000 bracket paying 30% plus the 2% Medicare levy, a savings account would need to pay about 8.8% to match a 6.00% offset. In the $135,001 to $190,000 bracket, 37% plus 2%, it would need about 9.8%. No savings account is paying that.

## Hack 1: have your salary paid into the offset

Every dollar in the offset for even one day reduces that day's interest. If your household earns $12,000 a month and it lands in the offset on the first of the month, the average balance across the month is far higher than if it goes into a transaction account and drips out. Over a year, that difference alone is worth hundreds of dollars, and it costs nothing.

## Hack 2: spend on a credit card and pay it in full

Put everyday spending on a credit card with an interest-free period, leave your cash in the offset for the whole month, then pay the card in full from the offset on the due date. Your money spends up to 55 days reducing your mortgage interest before it leaves.

This only works if you pay the card in full, every month, without exception. If you carry a balance, the card interest wipes out the benefit many times over. If you know you will not be disciplined, skip this one.

## Hack 3: park everything in the offset, including your emergency fund

Your emergency fund, your holiday savings, your tax provision if you are self-employed, and any bonus or tax refund should sit in the offset rather than a separate savings account. The money is just as accessible and it is working harder. Many lenders let you open several offset accounts on one loan, so you can label them "emergency", "car", "holiday" and keep your budgeting habits without losing the interest benefit. Ask us which lenders offer multiple offsets.

## Hack 4: do not let a lump sum sit in the wrong place

Selling a car, receiving an inheritance or getting a work bonus? Into the offset the same day. For illustration, $20,000 sitting in a transaction account for three months while you decide what to do with it costs you about $300 in interest on a 6.00% loan. Decide later; offset now.

## Hack 5: understand offset versus redraw

Redraw lets you take back extra repayments you have made, but the lender controls the terms, can limit or freeze access, and moving money out of redraw and back in is slower. Offset money is yours in a normal transaction account. For investors there is a critical tax difference too: redrawing from an investment loan for personal use can contaminate the loan's deductibility, whereas withdrawing from an offset does not. Our [offset vs redraw guide](/guides/offset-vs-redraw/) explains both.

## Hack 6: make sure the offset is really 100%

Some loans offer partial offsets or offsets that apply only to a fixed portion. Some basic loans offer none at all in exchange for a slightly lower rate. If your offset balance is regularly above $10,000 to $20,000, a full offset usually beats a marginally lower rate. If you keep almost nothing in it, the cheaper loan with redraw may be better. Run the comparison in the [loan comparison calculator](/calculators/loan-comparison/).

## Hack 7: use the offset on a split loan

If you fix part of your loan for certainty, keep the offset linked to the variable portion and make sure the variable portion is large enough to absorb your savings. Fixing 100% of a loan usually means losing the offset entirely for the fixed term. The [split loan calculator](/calculators/split-loan/) helps you size the portions.

## Hack 8: review the loan, not just the offset

An offset only helps if the underlying rate is competitive. A great offset on a loan that is 0.50% above the market is losing you more than the offset saves. Check your rate yearly. If your lender will not reprice, our [refinancing service](/services/refinancing/) and [when to refinance guide](/guides/when-to-refinance/) explain the options, and many refinances are at no cost to you for our home-loan service.

## A simple monthly routine

1. Salary lands in the offset on payday.
2. Bills and groceries go on the credit card.
3. Card is paid in full from the offset on the due date.
4. Any leftover money stays in the offset. Nothing moves to a savings account.
5. Once a year, check the rate against the market and check the offset balance against the fee, if any.

## Frequently asked questions

### Is an offset account better than making extra repayments?

Financially they are similar dollar for dollar, because both reduce the balance on which interest is calculated. The offset wins on flexibility: the money stays accessible without asking the lender, and for investment loans it protects tax deductibility. Extra repayments suit people who want the money out of reach. Many borrowers do both.

### Does money in an offset account earn interest?

No. Offset balances earn nothing, but they reduce the interest charged on your loan at your loan rate, which is almost always higher than any savings rate. Because the saving is not taxable income, it is worth more than the equivalent savings interest, particularly for borrowers on higher marginal tax rates.

### Can I have an offset account on a fixed rate loan?

Most fixed rate loans do not offer a full offset, and some offer none. The usual solution is a split loan, with the offset linked to the variable portion. Make sure the variable portion is large enough to hold your savings, or the benefit is capped. Ask before you fix.

### Are there fees for an offset account?

Some lenders charge a package or account fee for loans with offset accounts, while others include it free. If you keep a meaningful balance in the offset, the interest saved usually exceeds any fee many times over. If your balance is small and the fee is high, a basic loan with redraw may suit better.
