Can You Have an Offset Account With a Fixed Loan?

Yes, you can have an offset account with a fixed loan when that lender’s fixed product permits it. The benefit can be full, partial or unavailable, depending on the product and fixed term. A split loan can provide offset access through an eligible variable portion while the fixed portion keeps its own rules.

The deciding question is which loan portion receives the interest benefit. Having an accessible transaction account beside a fixed mortgage doesn’t establish that its balance reduces the fixed loan’s interest.

Confirm Fixed-Loan Offset Eligibility

Fixed-loan offset eligibility belongs to the named product and fixed term, so two loans from the same lender can have different answers. Record the exact product before comparing its offset feature.

For example, ANZ’s eligible-loan list, as at October 2026, includes one-year ANZ Fixed Rate Home Loans for ANZ One offset. Its listed fixed terms for this feature are one year. Extending that eligibility to a two-year fixed loan would give the wrong answer.

Bendigo Bank’s offset page, as at October 2026, lists full offset on fixed Flex and Complete Home Loans. It lists partial offset for fixed Express Home Loans. The lender name alone therefore doesn’t tell you how much interest the account saves.

For your selected fixed rate home loan, retain these details together.

• The lender, product name and fixed term.
• The eligible loan portion and its account identifier.
• The offset account type and the required ownership match.
• The offset percentage or reduced-rate calculation, including any balance cap.
• The loan, package and offset-account fees.
• The terms’ effective date and when the offset benefit starts.

A rate quote and a generic offset brochure don’t establish the whole arrangement. Match the selected fixed product to its feature terms and the proposed loan structure.

Distinguish Full, Partial and No Offset

A full offset reduces the linked loan’s interest-bearing balance dollar for dollar within the product’s limits. Partial offset gives a smaller benefit, while an ineligible fixed loan receives none from money held in a transaction account.

This fictional comparison uses a $300,000 fixed loan and $20,000 held in a separate account. The 50% offset is an illustrative percentage, not a current lender offer.

Treatment	How the $20,000 counts	Balance charged at the full loan rate	Consequence
Full, 100% offset	All $20,000 counts	$280,000	Interest is calculated on the reduced balance
Illustrative 50% offset	$10,000 counts	$290,000	The saving is half that of full offset at the same loan rate
No offset eligibility	None counts	$300,000	Accessible cash supplies no fixed-loan interest benefit

Some partial-offset products use a reduced rate on a matching loan amount instead of a percentage deduction. Bendigo Bank’s fixed Express treatment, as at October 2026, charges 1.89% a year on the loan amount matching the linked Everyday Account balance. The rest attracts the regular loan rate.

Under that treatment, the account-matched amount still attracts interest. Calling it a 100% offset would overstate the saving. The published reduced rate is subject to change.

An offset also doesn’t automatically reduce the required repayment. With principal-and-interest repayments, a lower interest charge can leave more of the same repayment reducing principal. The loan’s repayment terms still apply.

Moneysmart’s offset guidance distinguishes separate offset money from extra repayments held within a loan and accessed through redraw. Redraw depends on the loan’s access rules. An ordinary transaction account can remain available for spending while providing no offset benefit on an ineligible fixed portion.

A fully offset mortgage needs eligible full-offset funds matching the linked outstanding balance, within any cap. Full offset describes how eligible cash counts, not a promise that every dollar of the mortgage attracts zero interest. The general offset account guide explains the daily calculation in more detail.

Compare a Fixed Portion With a Split Loan

A fixed-variable split can link an offset to an eligible variable portion without reducing interest on the fixed portion. Each portion keeps its own rate and repayment terms. Extra repayments into the fixed portion remain subject to that fixed product’s limits.

ANZ’s split-loan example, as at October 2026, links optional ANZ One offset access to an ANZ Standard Variable portion. It keeps the fixed portion separate. Choosing a variable portion that lacks offset eligibility wouldn’t produce that benefit.

Consider this fictional $600,000 split loan. It has a $400,000 fixed portion with no offset eligibility and a $200,000 variable portion with 100% offset. The borrower holds $50,000 in the offset linked only to the variable portion.

Loan portion	Outstanding balance	Eligible offset deduction	Balance used for interest
Fixed	$400,000	$0	$400,000 at the fixed rate
Variable	$200,000	$50,000	$150,000 at the variable rate

The correct calculation leaves the fixed portion at $400,000. An incorrect calculation subtracts the same $50,000 from both portions and shows $350,000 fixed plus $150,000 variable. That counts the cash twice.

If the offset balance later reaches $220,000, the $200,000 variable portion is fully offset in this example. The remaining $20,000 doesn’t reduce the ineligible fixed portion’s interest. This matters when sizing the variable portion against the cash you expect to retain.

A larger variable portion gives more room for offset cash but exposes more of the loan to variable-rate changes. Use the split home loan guide for the broader decision about the fixed-variable ratio and repayments.

Check Costs and Product Restrictions

A fixed home loan with an offset account is worth comparing on total cost for the cash you expect to hold. Use the same loan amount and comparison date for each option. Include the rate after any discount, package fees and separate account fees.

Moneysmart explains that a low offset balance can fail to justify higher rates or fees. A large balance on payday isn’t the same as money that stays in the account throughout the month. Model planned withdrawals as well as savings.

This fictional one-year comparison uses a constant $300,000 balance and ignores principal repayments to isolate the offset’s value. All rates, fees and balances below are illustrative, not current offers. The offset product has full offset with no balance cap.

Item	Fixed product without offset	Fixed product with offset
Annual interest rate	5.90%	6.00%
Annual additional feature fee	$0	$200
Interest and feature fee with $20,000 constant offset cash	$17,700	$17,000
Interest and feature fee with $2,000 constant offset cash	$17,700	$18,080

At $20,000, the offset product costs $700 less over the illustrative year. At $2,000, it costs $380 more. The $17,000 result is $280,000 at 6% plus $200, while $18,080 is $298,000 at 6% plus $200.

A partial offset or a balance cap reduces the saving, so substitute that product’s actual calculation before comparing. Also include establishment or switching costs when they differ between the options.

Fixed-loan repayment restrictions remain separate from offset access. ANZ’s fixed-loan terms, as at October 2026, allow a yearly tolerance without triggering an Early Repayment Cost. The tolerance is the lesser of $5,000 or 5% of the loan amount at the start of the current fixed period.

Exceeding that tolerance, fully repaying or refinancing during the fixed period can trigger that cost. Depositing cash in a separate offset account and paying extra into the loan are different actions. Apply the lender’s extra-repayment rules to the latter.

Before choosing, compare the fixed term’s offset eligibility, any cap and what happens when the fixed period ends. A product that saves money at your expected balance can suit you even if another borrower’s lower balance makes it poor value.

Verify the Structure Before Settlement

Before settlement, match the approved loan portions and offset arrangement to the loan offer and lender’s applicable terms. Keep enough detail for the borrower and broker to identify exactly where the cash will reduce interest.

1. Record each fixed and variable portion’s amount, product, rate basis and fixed-term dates.
2. Name the offset account linked to each eligible portion, including the ownership requirements and linkage start date.
3. Record the full-offset percentage or partial-offset calculation, any cap and each applicable fee.
4. Retain the lender source and its effective date with the approved structure and any written clarification specific to the application.

The expected result is an arrangement that identifies the loan portion receiving the offset benefit. If the fixed portion is ineligible, the documents must place the offset against an eligible variable portion for the proposed split to work.

An unresolved mismatch between the offer and the intended linkage needs a corrected arrangement before you rely on the projected saving. For opening, re-linking or checking the account after settlement, follow the offset account link-check guide. It also covers the evidence to collect if the interest benefit isn’t being applied.
