An offset account can save you thousands in interest on your first home loan, but only if it fits the way you actually manage your money.
Most first home buyers are choosing between a package that includes an offset account and a lower-rate option without one. The decision comes down to whether you're likely to keep enough cash sitting in the account to justify the additional fees or slightly higher rate that often comes with it.
What an offset account actually does
An offset account is a transaction account linked to your home loan. The balance in the offset account reduces the amount of interest you pay on your loan without reducing the loan balance itself. If you have a $500,000 home loan at a variable rate and you keep $20,000 in your offset account, you only pay interest on $480,000. You can access the money in the offset account whenever you need it, and the offset calculation updates daily.
Consider a buyer who purchases their first home in Redcliffe with a 10% deposit. They save $25,000 for their deposit and another $8,000 to cover stamp duty concessions and settlement costs. After settlement, they have $5,000 left over, which they deposit into their offset account. That $5,000 immediately starts reducing the interest charged on their loan. Over the course of a year, depending on their rate, that could save them several hundred dollars in interest compared to leaving the money in a standard savings account or spending it.
When an offset account makes sense for a first home buyer
You'll benefit from an offset account if you regularly have surplus income that you're not ready to lock away. If your income fluctuates, if you're building up funds for a renovation or parental leave, or if you simply prefer to keep a buffer without tying it up in your loan, an offset account gives you both flexibility and interest savings.
The alternative is a redraw facility, which lets you withdraw extra repayments you've made on your loan. Redraw can be more restrictive. Some lenders limit how often you can redraw, charge fees, or require minimum withdrawal amounts. An offset account gives you full access to your own money at any time, just like a regular transaction account.
In our experience, first home buyers who are also managing irregular income or planning for upcoming expenses within the first few years of ownership find the flexibility of an offset account worth the cost. If you're planning to use the Australian Government 5% Deposit Scheme and you're entering the market with a smaller deposit, you may have less surplus cash initially, which can make the offset less valuable in the short term.
Comparing the cost of an offset account to the benefit
Most lenders either charge a package fee for a home loan with an offset account or offer a slightly higher interest rate on loans that include one. Package fees typically range from $300 to $400 per year. Some lenders offer offset accounts with no package fee but apply a rate that's 0.10% to 0.20% higher than their lowest advertised variable rate.
If you're paying a $395 annual package fee, you need to keep enough in your offset account to save more than $395 in interest each year for the account to be worthwhile. At current variable rates, that usually means keeping at least $10,000 to $15,000 in the account consistently. If your balance sits closer to $2,000 or $3,000 most of the time, you're paying for a feature that's not delivering value.
As an example, a buyer with a $450,000 loan who keeps an average balance of $15,000 in their offset account over the year might save around $900 in interest. After paying the $395 package fee, they're still ahead by around $500. If the same buyer only keeps $5,000 in the account on average, the interest saved might only be $300, which means they're paying more in fees than they're saving.

Using an offset account with a fixed rate loan
Most lenders do not offer offset accounts on fixed rate loans. If you fix part or all of your home loan, the offset account will usually only work on the variable portion. If you're considering a split loan strategy, where part of your loan is fixed and part is variable, you can still use an offset account against the variable portion.
This setup works well if you want the certainty of a fixed rate on the majority of your loan but want to keep some flexibility with an offset account on the remainder. If you fix $350,000 of a $450,000 loan and leave $100,000 on a variable rate with an offset account, any balance you hold in the offset will only reduce the interest charged on that $100,000 variable portion.
Some lenders do offer offset accounts on fixed rate loans, but the choice is limited and the rates are often less competitive. If having an offset on your entire loan balance is a priority, you may need to stay fully variable or accept a higher fixed rate to access that feature.
What to watch for when choosing a home loan with an offset account
Not all offset accounts are structured the same way. A full offset account reduces your loan interest by 100% of the balance you hold in the account. A partial offset account only offsets a portion of the balance, such as 60% or 80%. Partial offset accounts are rare now, but they still exist with some lenders. Always confirm that the offset account being offered is a full offset.
Some lenders allow multiple offset accounts linked to the one home loan. This can be useful if you want to separate your everyday spending money from funds you're setting aside for a specific purpose, such as a future renovation or a new car. Each linked account contributes to the total offset balance, so having two accounts with $10,000 in each has the same impact as one account with $20,000.
Package fees sometimes include other benefits, such as fee waivers on credit cards, discounted rates on personal loans, or no annual fee on transaction accounts. If you're likely to use those features, the package fee may deliver value beyond just the offset account. If you're not going to use the extras, don't pay for them.
Offset accounts and deposit options for Queensland first home buyers
If you're purchasing in Queensland and using the $30,000 First Home Owner Grant or the stamp duty concessions available on new or established homes, the funds you receive from those concessions don't change how your offset account works. The grant is paid after settlement, so it won't reduce your deposit requirement, but once received it can be deposited into your offset account to start reducing your interest immediately.
Queensland first home buyers purchasing an established home under $700,000 pay no transfer duty, and those purchasing between $700,000 and $800,000 receive a partial concession. On a new build, the full transfer duty concession applies with no price cap. The money you save on stamp duty can be used to increase your deposit, cover settlement costs, or build up your offset account balance after settlement. Many buyers in Brisbane or the Gold Coast use those savings to establish a decent starting balance in their offset account rather than spending down to zero at settlement.
If you're using a low deposit option such as the Australian Government 5% Deposit Scheme, you may have less cash left over after covering your deposit and settlement costs. In that scenario, it can make sense to start with a loan that doesn't include an offset account, then refinance to add one once you've built up more savings. Refinancing to access features like an offset account is common, and it's something we regularly help first home buyers with once their financial position has improved. You can read more about refinancing options on our refinancing page.
