Offset Account vs Redraw: What's the Difference and Which Is Better?

First, the simple version

Both an offset account and a redraw facility do the same basic thing: they use your spare cash to reduce the interest you pay on your home loan. The difference is in how you access that cash, how disciplined you have to be, and what it means at tax time if the loan is for an investment.

Get the choice right and you can save a meaningful amount of interest over the life of the loan without locking your money away. Get it wrong, and an investor in particular can accidentally chip away at a tax deduction. Here is how each one works, plainly.

How an offset account works

An offset account is a regular everyday transaction account that sits alongside your home loan. It usually comes with a debit card, BPAY and online banking, just like any other account, and you can move money in and out whenever you like.

The clever part is that the balance in that account is offset against your loan balance before interest is calculated. The money is not actually paid onto the loan, it just counts against it day by day.

Here is an illustrative example (assumptions: a $600,000 variable home loan, a rate of around 6.2% p.a., and $50,000 sitting in the offset). With that $50,000 in the offset, interest is charged on roughly $550,000 instead of the full $600,000. At around 6.2% that is roughly $3,100 less interest over a year than you would otherwise pay, and your $50,000 is still right there to spend or move whenever you want. The more you keep in there, and the longer it stays, the more you save, but the numbers will be different for every loan.

Because the money never technically touches the loan, this is a clean, flexible way to park your savings, your salary and your emergency buffer while still cutting your interest.

How redraw works

Redraw is a feature attached to the loan itself rather than a separate account. When you pay more than your minimum repayment, those extra dollars go onto the loan and immediately reduce the balance you are charged interest on. Redraw is simply the ability to pull some of those extra repayments back out later if you need them.

So if your loan balance is $400,000 and you have made $50,000 in extra repayments, interest is charged on around $350,000. The interest saving works much the same way as an offset. The difference is that the money is inside the loan, and you have to actively redraw it to get it back.

The practical differences that actually matter

On paper the interest saving is similar. In real life, a few differences decide which one suits you.

• Access and liquidity. An offset works like a normal bank account, so your money is on tap with a card. Redraw usually means logging in and requesting the funds, it can take a little longer, and some lenders set minimum redraw amounts or limits.
• Discipline. This cuts both ways. Money in an offset is very easy to spend, which suits some people and tempts others. Money in redraw feels a little more out of reach, which can help you leave it alone and pay the loan down faster.
• Fees and availability. Redraw is often free or low cost. Offset accounts can carry a small fee or sit inside a packaged loan with an annual fee, and some lenders limit how many you can have. It is worth weighing any fee against how much you would realistically keep in the account.
• Fixed versus variable. Offset accounts are generally a variable rate feature. On a fixed rate loan many lenders do not offer a full offset at all, or only a partial one capped at a small amount, and redraw on fixed loans is often limited too. A common workaround is to split the loan, keeping a variable portion with an offset and a fixed portion for rate certainty.

The investor catch: redraw can muddy your tax deduction

This is the part that trips people up, and it is the single most important reason an investor often leans towards an offset.

For an investment loan, the interest is generally tax deductible because the borrowed money was used to produce income (the rent). The Australian Taxation Office looks at the purpose the money is used for, not just what the loan was originally for.

The catch with redraw is that the ATO treats redrawing money as a brand new borrowing, judged on what you spend it on. So if you redraw from your investment loan to pay for something private, like a car or a holiday, that portion of the loan is no longer used for investment, and the interest on it is no longer deductible. The loan becomes a mixed purpose loan, and you (and your accountant) then have to apportion the interest between the deductible and non-deductible parts for as long as the loan runs. It can get messy quickly.

An offset account sidesteps this. Drawing money out of an offset is not a new borrowing in the ATO's eyes, it is just you spending your own savings, so it does not change the purpose of the loan or touch your deduction. That is why investors are often steered towards keeping spare cash in an offset rather than parking it inside the loan via extra repayments and redraw.

This is general tax information, not tax advice. The detail matters here, so please check your own situation with your accountant before relying on it. If you do not have one, I am happy to point you to people I trust.

So which is better?

There is no single right answer, it genuinely depends on you.

• Owner-occupiers can do well with either, since the tax issue does not apply to your own home. If you want your savings and salary working hard while staying fully accessible, an offset is a great fit. If you are worried you will spend money that is too easy to reach, redraw can quietly enforce some discipline, and it is often cheaper.
• Investors usually benefit from an offset, because it keeps your savings working against the interest without ever putting your tax deduction at risk. Many investors keep their own home loan and investment loan separate and use an offset against the one they want to pay down first.
• For a lot of people the answer is a loan that offers both. Plenty of variable loans come with an offset and redraw, so you are not forced to choose. The trick is using each one for the right job, and that is where a quick chat can save you money.

A quick word before you decide

Features are only half the picture. A loan with a flashy offset but a higher rate or a chunky annual fee can easily cost you more than a simpler loan, especially if you would only ever keep a few thousand dollars in the account. The right setup balances the rate, the fees and the features against how you actually manage your money.
