What is an offset account and how does it work?
An offset account is a transaction account linked to your home loan that reduces the interest you pay. The balance in the offset account is deducted from your loan balance before interest is calculated, so you pay interest on a smaller amount.
Consider a buyer in Canning Vale who borrows for an owner-occupied property and keeps $25,000 in a linked offset account. If the loan balance is $500,000, interest is only calculated on $475,000. At current variable rates, that difference saves several thousand dollars annually while keeping the $25,000 fully accessible for school fees, rates, or other household expenses.
The account works like any standard transaction account. You can deposit your salary, withdraw for everyday spending, and use it for BPAY or transfers. The more you keep in the account, the less interest you pay. The balance fluctuates throughout the month, and the offset is calculated daily, so even short-term deposits create a saving.
Which lenders offer full offset accounts on variable rate loans?
Most major banks and many non-major lenders offer 100 per cent offset accounts on variable rate owner-occupied and investment loans. Not all lenders provide this feature on every product, and some apply restrictions based on loan type or LVR.
A full offset account reduces interest on the entire balance held in the account. A partial offset might only reduce interest on a percentage of the balance, such as 60 per cent or 80 per cent. Partial offsets are less common now but still exist in some lender product suites, particularly on fixed rate or introductory products.
When comparing home loan options, confirm whether the product includes a full offset and whether the lender charges an annual fee for the account or a higher interest rate to include the feature. Some lenders bundle offset accounts into their standard variable products at no additional cost. Others charge a monthly or annual package fee that also includes features like redraw, rate discounts, or fee waivers.

Can you use an offset account on a fixed rate home loan?
Most lenders do not offer offset accounts on fixed rate loans. A small number of lenders provide a partial offset on fixed products, typically capping the offset at 60 per cent of the account balance or limiting the offset balance to a set dollar amount.
If rate certainty is a priority but you also want to offset savings, a split loan structure may be the answer. You fix a portion of the loan and leave the remainder on a variable rate with a full offset account attached. The fixed portion provides predictable repayments, and the variable portion allows you to reduce interest with surplus cash.
In a scenario where a borrower in Canning Vale fixes 60 per cent of the loan and leaves 40 per cent variable with offset, they lock in repayments on the majority of the debt and still benefit from depositing bonuses, tax refunds, and other lump sums into the offset to reduce interest on the variable portion. That combination suits households with stable income who still want flexibility for irregular cash flow. We regularly see this structure used by families in the area who work in the surrounding industrial precincts or Murdoch health and education sectors and receive annual performance payments or shift allowances.
How much can you save with an offset account in Canning Vale?
The saving depends on your loan balance, the amount you keep in the offset, and the interest rate on your loan. The higher your offset balance and the longer you maintain it, the more you save.
For a household maintaining an average offset balance of $30,000 on a $450,000 variable rate loan, the reduction in interest paid can exceed $1,200 per year at current variable rates. That saving grows if you increase the offset balance or maintain it over multiple years. The compounding effect means you also reduce the amount of interest charged on interest, which accelerates equity build over time.
Canning Vale has a mix of established family homes near Livingston Marketplace and newer estates in the southern pocket near Nicholson Road. Buyers in these areas often use offset accounts to manage savings for extensions, solar upgrades, or private school fees while keeping those funds accessible rather than locked into the loan as additional repayments.
Unlike making extra repayments directly onto the loan, funds in an offset remain fully available without needing to apply for redraw or wait for lender approval. That makes offset accounts particularly useful for households managing irregular income, contract work, or planned expenses within the next 12 to 24 months.
Offset accounts and investment properties
Offset accounts on investment loans work the same way as on owner-occupied loans, but the tax treatment is different. Interest on an investment loan is generally tax-deductible, so reducing that interest also reduces your deduction.
If you have both an owner-occupied loan and an investment loan, keeping surplus funds in an offset account linked to the owner-occupied loan usually provides a greater after-tax benefit. The interest on the owner-occupied loan is not deductible, so every dollar saved is a genuine reduction in cost. Reducing interest on the investment loan saves money but also reduces your deductible expense.
In our experience, investors in Canning Vale who own their home and hold one or more rental properties often structure their loans to maximise offset on the non-deductible debt first. If both loans are with the same lender, it may be possible to link a single offset account to the owner-occupied loan and leave the investment loan without offset, preserving the full deduction while still benefiting from reduced interest where it delivers the highest after-tax saving.
Should you refinance to access an offset account?
If your current loan does not include an offset account and you are holding savings in a standard savings account earning minimal interest, refinancing may be worth considering. The interest saved by offsetting can far exceed the interest earned in most deposit accounts, particularly in the current rate environment.
Before refinancing, compare the interest rate and fees on the new loan with what you currently pay. Some lenders offer offset accounts only on premium variable products with higher rates or annual package fees. If the rate increase or fee outweighs the offset benefit, refinancing may not deliver a net saving.
A loan health check can identify whether your current loan structure matches your financial position and goals. If you have built up equity, reduced your LVR, or improved your credit profile since you first borrowed, you may also qualify for a lower rate or better product features when refinancing, making the move more worthwhile.
Offset accounts and loan serviceability
Lenders assess your ability to service a loan based on your income, expenses, and existing commitments. The balance in an offset account does not increase your borrowing capacity, but it does reduce your net interest cost and improve your cash flow position after settlement.
If you are applying for a new loan or looking to increase your borrowing, maintaining a consistent offset balance demonstrates savings discipline and may support your application by showing genuine savings and responsible financial management. However, lenders calculate borrowing capacity based on your income and liabilities, not the balance in your offset account.

Frequently Asked Questions
What is the difference between an offset account and a redraw facility?
An offset account is a separate transaction account that reduces the interest charged on your loan without reducing the loan balance itself. A redraw facility allows you to withdraw extra repayments you have made directly onto the loan. Offset balances remain accessible at all times, while redraw may require lender approval and can be restricted or removed.
Can I have more than one offset account on the same home loan?
Some lenders allow multiple offset accounts to be linked to a single loan, which can help with budgeting or separating funds for different purposes. Not all lenders offer this feature, and where it is available, limits may apply on the number of accounts or the total offset balance. Check with your lender or broker for specific product terms.
Do all home loan products include an offset account?
No, not all products include an offset account. Most variable rate loans from major lenders offer offset as a standard or optional feature, but fixed rate loans generally do not. Some low-rate or basic variable products exclude offset to keep the advertised rate lower. Always confirm whether offset is included and whether any additional fees apply.
Is the interest saved with an offset account taxable?
No, the interest you save by using an offset account is not considered taxable income. You are simply paying less interest on your loan rather than earning interest in a separate savings account. This makes offset accounts particularly tax-effective compared to earning interest in a standard deposit account.
Can I use an offset account if I have an investment loan?
Yes, many lenders offer offset accounts on investment loans. However, reducing the interest on an investment loan also reduces your tax deduction. If you have both an owner-occupied and an investment loan, directing surplus funds to an offset linked to the owner-occupied loan usually delivers a greater after-tax benefit.
