In short: An offset account is a transaction account linked to your home loan; its balance is deducted from the loan balance before interest is calculated, and the money stays yours to spend. A redraw facility lets you take back extra repayments you have made, subject to lender rules. Both cut interest; offset keeps more control and preserves tax deductibility if the property later becomes an investment.
Nearly every Melbourne home loan comes with one or both of these features, and they can save tens of thousands of dollars over the life of a loan if you use them well. The difference matters most when you value instant access to your money, when you might later rent out the property, or when you are deciding between a basic loan and a package loan with an annual fee. Here is how each works, what it is worth in dollars, and which one suits you.
How an offset account works
An offset account is a separate everyday account that sits alongside the loan. Your salary goes in, your bills come out, and every dollar sitting there at the end of each day is subtracted from your loan balance when the lender calculates daily interest.
If you owe $600,000 and have $30,000 in the offset, you are charged interest on $570,000. Your minimum repayment stays the same, so the interest saved goes toward principal and the loan finishes sooner.
Key features:
- The money is in your account, not the lender's. You can spend it, transfer it or withdraw it from an ATM without asking.
- It is a "100% offset" if every dollar counts. Some lenders offer "partial" offsets on fixed loans that only credit a percentage.
- It is usually only available on variable rate loans or a limited number of fixed products. See fixed vs variable rate.
- Package loans that include an offset often carry an annual fee of roughly $0 to $395, though many lenders now include offset on basic loans.
- You earn no taxable interest because you are saving interest rather than earning it, which is better than a savings account after tax.
How a redraw facility works
Redraw is a feature of the loan itself. When you pay more than the minimum repayment, the extra reduces your balance and your interest straight away. The lender then lets you "redraw" those extra repayments back out if you need them.
Key features:
- Extra repayments are technically repaid to the lender. You are drawing down debt again when you redraw, not withdrawing your own cash.
- Lenders can set minimum redraw amounts, charge fees, take a few days to process, or restrict redraw altogether, especially if you fall behind or the loan is in a fixed period.
- Redraw is usually free on variable loans and often unavailable during a fixed term.
- Some lenders reserve the right to recalculate your minimum repayment when you make large extra payments, which can reduce the amount available to redraw.
Offset vs redraw side by side
| Feature | Offset account | Redraw facility |
|---|---|---|
| Whose money is it? | Yours, in a transaction account | The lender's; you re-borrow when you redraw |
| Access | Instant: card, transfers, ATM | Online or branch; may take days; minimums may apply |
| Lender can restrict it? | No | Yes, at the lender's discretion |
| Available on fixed loans? | Rarely, sometimes partial | Often restricted during the term |
| Effect on interest | Identical dollar-for-dollar saving | Identical dollar-for-dollar saving |
| Annual fee | Sometimes ($0–$395 package fee) | Usually none |
| Tax if property later rented out | Loan interest stays fully deductible | Redrawn money for private use "contaminates" deductibility |
| Discipline | Easy to spend; needs self-control | Slight friction makes it harder to spend |
What an offset is worth: a $600,000 Melbourne example
Suppose you buy a house in Craigieburn and borrow $600,000 over 30 years at 6.00% p.a., for illustration. Your minimum repayment is about $3,597 a month.
You and your partner keep a combined $30,000 in the offset account: an emergency fund plus the float between paydays and bills.
| Scenario | Interest charged on | Approximate interest saved in year one | Approximate lifetime effect |
|---|---|---|---|
| No offset | $600,000 | Nil | Loan runs the full 30 years |
| $30,000 in offset, held steady | $570,000 | About $1,800 | Roughly 2.5 years and $70,000 of interest saved |
| $60,000 in offset, held steady | $540,000 | About $3,600 | Roughly 4.5 years and $125,000 of interest saved |
The saving compounds because every dollar of interest you avoid is a dollar of principal you repay instead. The offset calculator lets you test your own balance and rate.
The same result via redraw
If instead you paid that $30,000 into the loan as an extra repayment, the interest saving would be identical. The difference is purely about access, control and tax. For a couple who keep a stable emergency fund and never need to touch it, redraw does the job. For a couple who want to use the balance as their everyday account, or who might one day rent the house out, offset is clearly better.
The tax reason offset beats redraw for future investors
This is the most misunderstood point, and it matters in Melbourne's north where many families buy a first home in Wollert or Mickleham, then keep it as an investment when they upgrade.
The ATO looks at the purpose of borrowed money. Interest on a loan used to buy an income-producing property is deductible. If you pay $50,000 extra into the loan and later redraw it to buy a car or fund a holiday, that $50,000 portion of the loan is now for private use. When you turn the house into a rental, the interest on that portion is not deductible, and untangling mixed-purpose loans is messy for you and your accountant.
With an offset, the loan balance itself is never reduced by your savings. If you move out and rent the property, you withdraw the offset money for your next home, the full original loan balance becomes the investment debt, and the interest on all of it is deductible (provided the property is genuinely rented). This can be worth thousands of dollars a year. Our guide on using equity to buy an investment property explains how that transition works, and the ATO publishes rulings on mixed-purpose loans if you want the detail.
Choosing the right structure for your situation
First home buyer with modest savings
If you have $5,000 to $10,000 spare after settlement, the annual package fee for an offset can eat a meaningful share of your interest saving. At 6.00%, $10,000 in offset saves about $600 a year; a $395 package fee leaves you $205 ahead. A fee-free basic loan with redraw may be better until your balance grows, then refinance or switch products later. See our first home buyer loans service.
Household with $30,000 or more in savings
An offset almost always wins. The interest saved comfortably exceeds any fee, and having salary and savings in one place makes it effortless to keep every dollar working against the loan.
Self-employed or irregular income
Offset is ideal: tax money set aside for the ATO, quarterly BAS reserves and lumpy client payments all sit in the offset reducing interest until they are needed, with no risk of the lender restricting access. Read the self-employed home loan guide.
Buyer who may later rent the property out
Offset, for the tax reasons above. Do not make large extra repayments into a loan you may later want to treat as investment debt.
Fixed rate borrower
Most fixed loans have neither a full offset nor unrestricted redraw. If you want either, split the loan and attach the offset to the variable portion. See split loan calculator.
Getting the most out of an offset
- Have your salary paid into it. Even money that only sits there for a fortnight before bills go out reduces interest for those days.
- Use a credit card for monthly spending and pay it off in full from the offset on the due date, so your cash stays in the offset as long as possible. Only do this if you never carry a balance.
- Keep your emergency fund there rather than in a separate savings account earning less after tax.
- Park lump sums such as tax refunds, bonuses and sale proceeds in the offset while you decide what to do with them.
- Consider multiple offset accounts if your lender allows it, to separate bills, holidays and emergency savings while all of them offset the loan.
Getting the most out of redraw
- Round your repayment up. Paying $3,700 instead of $3,597 a month on the example loan builds a redraw buffer and cuts years off the loan. Test it with the extra repayments calculator.
- Check the redraw terms before relying on the money: minimum amounts, fees, processing time and whether the lender can refuse.
- Do not treat redraw as your emergency fund if the lender can restrict it. Keep some cash outside the loan.
- Never redraw for private spending on a property you might rent out later.
Common mistakes
- Paying a package fee for an offset you barely use. If your average balance is under about $7,000 at 6.00%, a $395 fee costs more than it saves.
- Assuming redraw money is guaranteed. Lenders have frozen redraw during hardship and product changes. Read the terms.
- Making big extra repayments on a future investment property. Use offset instead and keep deductibility intact.
- Leaving savings in a separate high-interest account. A 4.50% savings rate becomes about 3.15% after 30% tax; an offset at 6.00% is tax-free and beats it comfortably.
- Letting the offset balance drift to zero. The feature only helps if money actually sits there.
- Fixing the whole loan and losing both features for the term.
Frequently asked questions
Is an offset account worth it?
Usually yes if you keep more than roughly $7,000 to $10,000 in savings on average, because the interest saved at typical rates exceeds any annual package fee. With $30,000 in offset on a $600,000 loan at 6.00% you save about $1,800 a year and roughly $70,000 over the loan's life. With very little spare cash, a fee-free loan with redraw can be better.
Is redraw money mine?
Not in the way offset money is. Extra repayments reduce your debt, and redrawing them means borrowing again under the loan contract. The lender can set minimums, fees and processing times and can restrict redraw in some circumstances. Offset money sits in your own transaction account and is available without conditions, which is why offset is the safer place for an emergency fund.
Does an offset account reduce my repayments?
No. Your minimum repayment is set on the full loan balance and stays the same. What changes is how much of each repayment is interest versus principal. Because less interest is charged, more of every repayment reduces the debt, so the loan is paid off sooner and you pay less interest in total.
Can I have an offset account on a fixed rate loan?
Some lenders offer a full 100% offset on fixed loans, but most offer none or a partial offset. The common workaround is a split loan: fix one portion for certainty and keep a variable portion with the offset attached. Ask which lenders on our panel allow this before you fix.
Is offset better than redraw for tax?
Yes if the property may become an investment. Money withdrawn from an offset does not change the loan balance, so the full loan stays deductible once the property is rented. Money redrawn from the loan for private use makes that part of the debt non-deductible and creates a mixed-purpose loan that is hard to unwind.
Do I pay tax on offset savings?
No. You are not earning interest, you are avoiding it, so there is nothing to declare. That makes an offset more efficient than a savings account paying the same rate, because savings interest is taxed at your marginal rate while the interest you save on your loan is not.
