Offset account vs the rate premium it carries

Is an offset account worth the higher rate?

It depends on how much you keep in it. An offset account reduces the balance you're charged interest on, so money sitting in the offset works like extra repayments while staying available. But offset accounts often live inside a package that carries a slightly higher rate or an annual fee. The offset is worth it when the interest you save on your typical offset balance is greater than that rate premium or fee. With little in the offset, a no-frills loan at a sharper rate can win.

What is the actual offset rate premium right now?

Live figures from the same verified panel at 80% LVR, owner-occupier variable, as at 9 November 2026: the 22 products that include a full offset account average 6.69% p.a., the 18 products without one average 6.46% p.a., a 0.23 point gap above the no-offset average right now. Whether that premium is worth paying still comes down to the average balance kept in the offset, as the break-even check above sets out, not the premium alone.

When does an offset pay for itself?

An offset's interest saving depends on the balance you keep in it and the interest rate on the linked loan. Compare that saving with any additional interest and fees charged for the offset product. A larger loan does not automatically make an offset better value: a rate premium applies to more debt, while the benefit still depends on the money held in the offset. Access terms, eligible balances and whether the account provides a full or partial offset also matter.

An offset is only as valuable as the money you keep in it. If your balance is usually low, compare any additional fees or interest with the limited saving.

How can I compare an offset loan with a loan without offset?

Compare two actual offers for the same loan amount, repayment type and term. An average across different lenders cannot tell you the extra cost of adding an offset to your loan.

Estimate the interest saved using the money you expect to keep in the offset, then compare it with the extra interest and fees for that offer. Balances and rates can change, so a break-even estimate is a guide rather than a guaranteed saving.

• Check the interest rate and comparison rate for each offer, together with their stated assumptions.
• Include annual package fees, account fees and any other additional costs of the offset option.
• Confirm whether the account provides a full or partial offset, which balances qualify and how access works.
• Use a realistic average daily offset balance, rather than the largest balance reached on payday.

How do I work out my average daily offset balance?

Interest on most home loans is calculated daily, so a payday balance can overstate the saving. Add each day's eligible offset balance for the period, then divide by the number of days. Use several months if spending or savings are irregular.

For example, $20,000 held for five days and $5,000 held for the other 25 days gives a 30-day average of $7,500: ($20,000 x 5 + $5,000 x 25) / 30. This is a balance example, not an interest saving or a product quote. If the account provides a partial offset, confirm how much of that balance qualifies.

Use the balance actually held through the month. Money set aside for a bill stops reducing interest once it leaves the offset account.

Which costs belong in an offset break-even check?

Use two actual offers with the same loan balance, purpose, repayment type and remaining term. The extra cost is any additional interest on the offset loan plus its additional fees. Compare that with the interest avoided on the eligible average daily offset balance. A difference between monthly repayments is not the same as a difference in interest costs, because principal-and-interest repayments also reduce the debt.

A simple estimate assumes balances and rates stay constant. For a full offset with a balance below the linked loan balance, annual interest avoided is the eligible average offset balance multiplied by the offset loan's annual interest rate. Confirm any cap or excluded balance with the lender. Additional annual interest is the loan balance multiplied by the difference between the two interest rates. Express the rates as decimals, then add any additional annual fees. Changing balances, rates, upfront charges and how cash would be used on the alternative loan can change the result.

How can I check that my offset is working?

An offset balance reduces interest only when the account is linked to an eligible loan. Confirm that link in the lender's app, online banking or statements. If the interest saving is unclear, ask the lender to explain which account and loan balances it used.

Check the link again after refinancing or switching loan products. MoneySmart warns that a loan change can require an offset account to be linked again. Unchanged scheduled repayments do not prove the offset is working: the benefit may instead appear as less interest and more principal repaid.

Offset account vs redraw: what's the difference?

Both let you use extra money to cut interest, but they work differently. An offset is a transaction account linked to your loan, so the balance remains in that separate account. Redraw lets you pull back extra repayments you've already made, but the lender can change redraw terms and the money is technically paid into the loan. Access, transaction limits and fees depend on the account and loan terms. Compare those terms alongside the interest cost before choosing between them.

• An offset saves interest only on the balance you keep in it.
• Weigh that saving against the package fee or rate premium.
• A steady offset balance can help, but additional interest and fees still need to be compared.
• If your balance runs low, a sharper no-frills rate can win.
