How Offset Accounts and Redraw Facilities Cut Interest on Your Home Loan in Australia

Key Takeaway

Offset accounts and redraw facilities both reduce the interest you pay on an Australian home loan, but they work differently. An offset account is a separate transaction account linked to your loan: every dollar in it reduces the balance on which interest is calculated, cutting your interest charges without you making extra repayments. A redraw facility lets you deposit extra repayments above the minimum, then withdraw those extra funds later if needed, which also lowers interest in the meantime. Offset accounts offer more flexibility and immediate access to your money, while redraw may have restrictions or fees.

How an Offset Account Works

An offset account is a transaction account (like an everyday bank account) that you link to your variable-rate home loan. The balance in the offset account is subtracted from your loan balance before your lender calculates daily interest. For example, if you owe A$400,000 and have A$20,000 in your offset account, you pay interest on only A$380,000. You earn no interest on the offset balance itself, but you save more in loan interest than you would earn in a standard savings account, because home loan rates are higher than savings rates.

According to ASIC MoneySmart, offset accounts are typically available with variable-rate loans and can save thousands of dollars in interest over the life of the loan. You can deposit your salary, savings, or any funds into the offset account, withdraw them at any time via debit card or transfer, and every dollar offsets your loan balance continuously. There is no limit on how often you can add or withdraw money, making it a flexible tool for managing cash flow while cutting interest.

Most lenders charge a higher interest rate or an annual fee for loans with a full offset account (commonly A$200 to A$400 per year as of October 2026, though fees and rates change frequently). Partial offset accounts (which offset only a percentage of the balance, such as 60 per cent) cost less but save less. Run the numbers: if the annual fee is A$300 and you keep A$20,000 in offset on a 6 per cent loan, you save around A$1,200 per year in interest, making the fee worthwhile.

How a Redraw Facility Works

A redraw facility lets you make extra repayments on top of your minimum monthly payment, then redraw (withdraw) those extra amounts later if you need the cash. The extra repayments sit in your loan account and reduce the principal, so you pay less interest. For instance, if your minimum monthly repayment is A$2,000 and you pay A$2,500, the extra A$500 goes toward principal and you can redraw it later, subject to your lender’s terms.

Redraw is common on both variable-rate and fixed-rate loans (though fixed-rate redraw often has limits or fees). According to educational texts such as Principles of Finance, extra principal repayments shorten the loan term and reduce total interest, and the redraw feature adds the flexibility to access that equity without refinancing.

However, redraw is less flexible than offset. Many lenders impose a minimum redraw amount (such as A$500 or A$1,000), limit the number of free redraws per year, or charge a fee per redraw (commonly A$20 to A$50). Some lenders restrict online redraw, requiring you to phone or visit a branch. If you fix your loan, redraw may be blocked during the fixed period, or the lender may reduce your available redraw balance if you fall behind on repayments. Always check your loan contract: redraw is not guaranteed, and lenders can vary the terms.

Offset versus Redraw: Which Saves More?

Both features cut interest by the same amount if the balances are equal and the loan rate is the same. The difference is access and control. Offset keeps your money in a separate account under your full control, with instant access and no restrictions. Redraw locks the extra funds into the loan account, and you must request a withdrawal (and possibly pay a fee or wait for approval).

Offset is better if you want maximum flexibility, regular access to your savings, or plan to use the account for everyday banking (salary deposits, bill payments). Redraw suits borrowers who want to make lump-sum extra repayments (such as a work bonus or tax refund) and do not need frequent access, or who have a fixed-rate loan where offset is not available.

Tax treatment differs too: if you later convert your home into an investment property, money in an offset account does not reduce your deductible loan balance, but extra repayments that you redraw may affect your deductions (consult a qualified tax professional for your situation, as the Australian Taxation Office rules are specific to how you use the funds).

Next Steps

Compare home loan products with offset or redraw on Finder or MoneySmart’s home loan comparison tools, checking the annual fee, redraw conditions, and whether the feature is included or costs extra. Calculate your potential interest saving: if you can keep a consistent offset balance or make regular extra repayments, the interest saving typically exceeds any account fee within the first year. Speak to a licensed mortgage broker or your lender to confirm which feature is available on your current loan or a new loan you are considering, and verify the current terms (interest rates, fees, and redraw conditions change, and eligibility varies by lender and product).
