Your savings don't sit idle. In an offset, every dollar quietly cuts your interest.
An offset account is an everyday transaction account linked to your home loan. The lender charges interest on your loan balance minus whatever's sitting in the offset — calculated daily. Your money stays yours, fully accessible, but while it's there it works like extra repayments without ever being locked away. Here's how the saving builds, and why it grows when rates rise.
The more you park in the offset, the more interest you save — and the higher the rate, the steeper it climbs.
Annual interest saved as your offset balance grows against a $500,000 loan, shown at two indicative rates. Because the interest you avoid is charged at your loan rate, every dollar in the offset saves more when rates are higher — the blue bars sit above the lighter ones at exactly the same balance.
Illustrative worked example only — not a quote, an offer, or a guarantee of any saving. Figures assume a constant offset balance held against a $500,000 loan; the ~5.2% and ~6.2% rates are indicative comparison points, not current offers, and rates move with the RBA cash rate. First-year interest saved is simply the offset balance multiplied by the rate; the "5½ years" figure assumes $50,000 stays in the offset for the full 30-year term with the repayment unchanged. Your actual saving depends on your balance, rate, fees, loan size and how you use the account. Indicative benchmark: average new owner-occupier variable ~6.22% (RBA, May 2026).
Three things an offset does that a savings account can't.
Interest is charged on the difference
The lender calculates interest on your loan balance minus the offset balance. Owe $500,000 with $50,000 in the offset and you're charged as if you owed $450,000 — recalculated every single day.
The money stays yours
Unlike extra repayments, offset funds aren't paid into the loan — it's a full transaction account with card and transfers. You keep your liquidity and your emergency buffer while still cutting interest.
The benefit isn't taxed as income
Interest earned in a savings account is taxable. Interest you avoid through an offset isn't — the benefit effectively lands at your loan rate, untaxed. That's general information, not tax advice.
Offset vs redraw — same interest saving, very different money.
Both cut the interest you pay by reducing the balance it's charged on. The difference is where the money legally sits, how fast you can get it, and — for investors — how the tax works.
Offset account
Your own money, in a transaction account linked to the loan.
- It's your money — sitting in an everyday account, not paid into the loan.
- Instant access — card, transfers, ATM; no request, no approval, no delay.
- Reduces interest daily — dollar-for-dollar against the loan balance.
- Cleaner for investors — withdrawing your cash doesn't change the loan itself, which can matter for the deductibility of interest (confirm with your accountant).
- Often costs more — commonly attached to a package with an annual fee or a rate above a basic loan.
Redraw facility
Extra repayments you've made into the loan, that you can pull back.
- It's loan repayments — legally money you've paid ahead, not funds in your own account.
- Access can be slower — sometimes subject to minimums, limits, lender approval, or being reduced/withdrawn.
- Reduces interest too — the balance charged drops by whatever you're ahead.
- Tax care for investors — redrawing for personal spending can affect how much loan interest stays deductible; get advice first.
- Often free — available on many basic, lower-fee loans without a package.
The interest-saving effect is the same; the meaningful differences are access, legal ownership of the funds, and tax treatment. If you hold a healthy balance and want it available at all times, an offset usually wins on flexibility. If you typically hold little and want the lowest rate and fees, a basic loan with free redraw can leave you ahead — the break-even depends on your numbers. This is general information, not personal advice.
An offset is worth more, not less, when rates go up.
The saving from an offset is the interest you don't pay — and that avoided interest is charged at your loan rate. So when the rate rises, each dollar in the offset works harder. The same $50,000 that saves around $2,600 a year against a ~5.2% loan saves closer to $3,100 against a ~6.2% loan — the higher the rate climbs, the more valuable it is to keep your cash offsetting the loan rather than in a lower-yielding account.
Over 2026 the RBA cash rate rose +0.75 percentage points to 4.35%, so variable rates have stepped up — which is exactly the environment where an offset earns its keep. It also cuts both ways: if rates later fall, the per-dollar saving eases too. Either way, your money stays fully accessible the whole time.

Australians are leaning on offset and redraw more than ever.
Households have kept building their buffers — a big reason offset accounts have become a default feature request, not a nice-to-have.
Source: RBA Financial Stability Review, March 2026 — households have continued adding to offset and redraw accounts, with median prepayment buffers above pre-pandemic levels across income groups. This is a qualitative measure of household liquidity; no single national dollar total for offset balances is published, so we don't quote one. General information only.
Getting the most out of an offset
Route as much cash through the offset as you can — salary, savings, the emergency fund, money set aside for bills or tax. Some borrowers pair it with a credit card they clear in full each month, so their own cash keeps offsetting the loan for longer (that only works if the card is genuinely paid off). Want fixed-rate certainty and an offset? Offset is generally a variable feature, so a common answer is a split loan — fix part for stability and keep a variable portion with a full offset attached.
Strategies described are general information, not personal credit, tax or financial advice. Whether an offset beats a basic loan for you depends on your balance, rate, fees and loan size — we run that comparison across our panel.
Offset accounts, answered straight.
What's the difference between an offset account and a redraw facility?
An offset account is a separate everyday account linked to your loan — your money stays yours and reduces the balance interest is calculated on. A redraw facility holds extra repayments you've made into the loan itself, which you can usually take back out, sometimes with conditions. The interest effect is similar; the difference is access, ownership of the funds, and potential tax treatment for investors.
What's the difference between 100% offset and partial offset?
A 100% offset counts every dollar in the account fully against your loan balance when interest is calculated. A partial offset only counts a percentage of the balance, or applies a reduced interest benefit. Most modern offset products are 100%, but it's worth confirming — a partial offset can significantly change the value of the feature.
Do offset accounts cost more?
Often, yes — offset accounts are commonly attached to package loans with an annual fee, or to products priced above basic no-frills loans. Whether that cost is worth it depends on your average offset balance: the more you keep in the account, the more interest you save. We can run the break-even for your numbers across multiple lenders.
Can I get an offset account on a fixed rate loan?
Usually not — offset is predominantly a variable rate feature, and where it exists on fixed loans it's often only a partial offset. A common workaround is a split loan: fix part of the loan for rate certainty and keep part variable with a full offset attached.
How much money do I need in the offset for it to be worthwhile?
There's no universal figure — it depends on the fees you pay for the offset feature versus the interest saved at your loan's rate. As a rule of thumb, the interest saved on your average balance over a year needs to exceed any annual package fee and rate premium. If you typically hold only a small balance, a lower-rate basic loan with free redraw may leave you ahead.
Can I have more than one offset account?
Some lenders allow multiple offset accounts linked to the same loan, which is useful for separating bills, savings goals and emergency funds while every account still offsets the balance. Other lenders allow only one. If bucketing your money matters to you, it's a filter we can apply when comparing products.
Does an offset reduce my repayments or my loan term?
Your scheduled repayment generally stays the same. What changes is the split inside it: with money in offset, less of each repayment goes to interest and more reduces the principal. Over time that compounds — you pay the loan off sooner and pay less total interest, without changing your monthly commitment.
Are offset accounts useful for investment loans?
They can be. Many investors park surplus cash in an offset rather than paying down the loan, because it reduces interest while preserving the loan balance and its original purpose — which can matter for the tax deductibility of interest if funds are later needed for personal use. Tax outcomes depend on your circumstances, so confirm your structure with your accountant or tax adviser.
