Offset account vs redraw in Australia
Offset and redraw save identical interest on identical balances. What separates them is fees, legal certainty, fixed-rate limits and tax treatment.
Two ways to hold the same dollar
Two different mechanisms for reducing the interest you pay while keeping access to your money. An offset account is a transaction account linked to the loan: its daily balance is subtracted from the loan balance before interest is calculated, and the money stays yours in a deposit account. Redraw is the pool of extra repayments you have already made above the required amount, which the lender may allow you to draw back.
On the interest arithmetic they are identical. Forty thousand dollars sitting in an offset against a $600,000 loan at 6.09% saves exactly what $40,000 sitting in redraw saves on the same loan. Everything that distinguishes them is legal, tax, access and fee detail — which is precisely where the money is actually won or lost.
What the offset is worth on a real balance
Concrete numbers make the choice easier to see. On a $600,000 loan over 30 years at 6.09% the repayment is about $3,632 a month. A steady $40,000 in the offset cuts interest by roughly $2,440 in the first year, and if that balance stays put for the life of the loan while repayments are not reduced, it clears the loan close to five years early and saves in the order of $170,000 in interest. Both figures assume the balance genuinely stays there.
Against that sits the package fee most offset products carry — commonly $395 a year, occasionally up to $499 — and, at some lenders, a rate premium of five to fifteen basis points for the offset version of the same product. At $395 a year the fee is worth paying once your average offset balance is above roughly $6,500. Below that, a basic loan with free redraw is usually the cheaper structure.
Why redraw is the legally weaker of the two
Money in redraw has already been paid to the lender; you are asking for it back. That is not a technicality. Loan contracts routinely permit the lender to reduce or suspend redraw availability, impose minimum redraw amounts, or apply available redraw to arrears, and Australian lenders have exercised those clauses during stress periods. Offset money sits in your own deposit account and is covered by the Financial Claims Scheme up to $250,000 per account holder per authorised deposit-taking institution.
Redraw also thins out on a fixed rate. Most fixed loans cap extra repayments — $10,000 to $30,000 a year is the usual range — and many block redraw entirely until the fixed term ends. Offset against a fixed rate is either unavailable or partial, sometimes a full offset limited to a portion of the balance. If you are fixing, check both features on the specific product rather than assuming the variable terms carried across.
The tax difference that costs investors most
This is why the two are not interchangeable for anyone whose home might one day be rented out. Interest is deductible according to the purpose the borrowed money was put to. Paying a loan down and later redrawing creates a new borrowing, and deductibility follows what the redrawn money is spent on — take $80,000 from redraw for a car and that portion is not deductible even after the property becomes an investment.
Money in an offset never touches the loan balance, so withdrawing it creates no new borrowing and does not contaminate the deduction. The rule most accountants give is simple: if there is any chance the home becomes a rental, save into the offset rather than into the loan. Mixed-purpose loans are difficult and expensive to unpick afterwards, and this is a question for your accountant rather than your broker.
Partial offsets, sub-accounts and timing
Not every product labelled offset is a full offset. Partial offset accounts credit only part of the balance, or credit it at a rate below the loan rate, and they turn up most often on fixed and some investor products. Multiple offset sub-accounts are useful for separating a settlement buffer from savings goals, but a handful of lenders charge per additional account or cap how many you can open.
The mechanical detail that matters most is when the balance is measured. Offset is calculated on the daily closing balance, so a salary that lands on the 15th and is spent by the 20th still earns five days of benefit. Redraw only reduces interest from the day the extra repayment is processed, and some lenders take a business day or two to post it. Neither is free money; both live inside the credit contract.
Choosing without over-engineering it
For most owner-occupiers with a stable balance the decision reduces to two questions: does your average offset balance justify the package fee, and could this property ever become an investment. A yes to the second usually settles it in favour of offset regardless of the first. If the home will never be rented and your buffer averages a few thousand dollars, redraw on a low-rate basic product is cheaper and simpler.
It gets genuinely complex on splits — part fixed, part variable with the offset attached to the variable portion — and that is worth modelling rather than guessing.

FAQ
Is an offset account better than redraw?
Usually, but not always. Offset wins on legal certainty, tax treatment and access, because the money stays in your own deposit account and is covered by the Financial Claims Scheme. Redraw wins on cost, since it comes free with basic loans while offset products typically carry a package fee of about $395 a year.
Does an offset account save more interest than redraw?
No, not on identical balances. Both reduce the amount interest is charged on, so $30,000 in either place saves the same at the same rate. The practical differences are that redraw only counts from the day the extra repayment posts, some lenders take a day or two to process it, and redraw can be restricted under the loan contract.
Can a bank take away my redraw?
Yes, where the loan contract allows it, and most do. Lenders can reduce a redraw limit, suspend availability, set minimum withdrawal amounts, or apply available redraw against arrears. If you are relying on redraw as an emergency fund, read the clause first, or hold the buffer in an offset or separate savings account instead.
Why is redraw a problem for investors at tax time?
Because redrawing creates a new borrowing, and deductibility follows what the money is spent on rather than what secures it. Pay a loan down, redraw $50,000 for a holiday, and that interest is not deductible even once the property becomes a rental. Offset withdrawals create no borrowing at all.
Can I have an offset account on a fixed rate loan?
Sometimes, but usually with restrictions. Many lenders offer no offset against a fixed rate; others offer a partial offset, or a full offset limited to part of the balance. Fixed loans also cap extra repayments, commonly between $10,000 and $30,000 a year, and often block redraw until the fixed term ends.
Is an offset account worth it on a small loan?
It depends on the balance you hold in it, not the loan size. A $395 annual package fee needs roughly $6,500 of average offset balance to break even at around 6%. Below that the fee costs more than the interest saved, and some lenders price the offset version five to fifteen basis points higher again.
How much does $50,000 in an offset save on a $600,000 loan?
About $3,000 in the first year at 6.09%, and more over time as the saved interest compounds into faster principal reduction. If the balance stays put and repayments are not reduced, it takes several years off the term. The annual saving falls as the loan balance falls, because interest is charged on the net amount.
Do offset accounts affect my borrowing power?
Not directly. Serviceability is assessed on income and commitments at your rate plus the 3 percentage point buffer, not on your savings. What an offset balance does change is the strength of your deposit and buffer evidence, and some lenders reduce the interest assessed on an existing investment loan held against one.
