The Easiest Way to Use Fixed Rates and Offsets

Fixed Rates Don't Always Lock You Out of an Offset

Most lenders don't attach offset accounts to fixed rate home loans. The offset facility typically sits with the variable portion of a split loan or a fully variable loan structure. Some lenders will allow a linked offset even when part of your loan is fixed, but the offset balance only reduces interest on the variable component.

Consider a buyer purchasing in Hobart under the Australian Government 5% Deposit Scheme with a 5% deposit. They fix 60% of the loan to lock in certainty on repayments, and leave 40% variable with a 100% offset account attached. Any savings sitting in the offset reduce the interest charged on the variable portion. The fixed portion continues to accrue interest at the agreed fixed rate regardless of what sits in the offset. That structure gives you rate protection on the majority of the loan and flexibility on the rest.

Why Splitting Matters More Than Most Buyers Realise

A split loan structure means you divide your total borrowing into two or more portions. You fix one portion at an agreed rate for an agreed term, and leave the remainder on a variable rate. The variable portion can have an offset account linked to it, depending on the lender's product features.

In a scenario where you borrow with a 10% deposit and split the loan 50/50, half your borrowing sits on a fixed rate and half on a variable rate with offset. You deposit your salary into the offset account. That balance reduces the interest charged on the variable half daily. Your fixed half remains unaffected. If you're building savings toward renovations or holding funds for upcoming costs, those savings reduce your interest bill while you wait.

This structure also reduces the impact of fixed rate expiry. When the fixed portion expires, only half the loan rolls to a variable rate at once. You're not exposed to a sudden jump in repayments across the entire loan amount.

How Offset Accounts Reduce Interest Without Reducing Your Loan Balance

An offset account is a transaction account linked to your home loan. The balance in the offset is subtracted from your loan balance before interest is calculated each day. You're not making extra repayments into the loan itself. Your savings remain accessible.

If your variable loan balance is $200,000 and you hold $30,000 in the linked offset, you're charged interest on $170,000. Your minimum monthly repayment stays the same, but more of that repayment goes toward reducing the principal rather than covering interest. The $30,000 stays in your offset account. You can withdraw it at any time without needing lender approval or paying a redraw fee.

For first home buyers using a low deposit option such as the 5% Deposit Scheme, holding savings in an offset rather than paying down the loan directly keeps those funds liquid. You avoid the risk of needing to redraw or reapply for access to your own money if an unexpected cost comes up.

Redraw Facilities Are Not the Same as Offset Accounts

A redraw facility lets you withdraw extra repayments you've made above the minimum required amount. If your minimum monthly repayment is $2,000 and you pay $2,500, the extra $500 reduces your loan balance. You can apply to redraw that $500 later if needed. Some lenders charge a redraw fee. Some set a minimum redraw amount. Others restrict how many redraws you can make in a year. Some lenders have removed redraw access entirely without notice during economic disruptions.

An offset account doesn't carry those restrictions. The balance never becomes part of the loan. It remains your money in a linked transaction account. You access it the same way you access any transaction account. No redraw application. No fees. No risk the lender changes the terms.

If you're comparing home loan options and a lender offers redraw but not offset on the variable portion, that's a weaker product for buyers who want reliable access to surplus funds.

Fixed Rate Break Costs Apply If You Exit Early

If you discharge a fixed rate loan before the fixed term ends, most lenders charge a break cost. The break cost compensates the lender for the difference between the rate you're paying and the rate they can now lend that money at. If rates have fallen since you fixed, the break cost can be substantial. If rates have risen, the break cost may be zero or minimal.

Break costs also apply if you refinance, sell the property, or make a lump sum repayment above the allowed threshold during the fixed period. Most lenders allow up to $10,000 or $20,000 in additional repayments per year on a fixed loan without penalty, but this varies by lender and product.

That's another reason to split rather than fix the entire loan. If your circumstances change and you need to refinance or sell, only the fixed portion attracts a break cost. The variable portion can be discharged without penalty. You reduce your financial exposure while still holding some rate certainty.

Tasmanian First Home Buyers Can Stack Schemes With Split Loans

Tasmania offers a $20,000 First Home Owner Grant for new homes for eligible transactions from 1 July 2026. That grant can be used alongside the Australian Government 5% Deposit Scheme. Buyers purchasing a new apartment in Hobart under the $700,000 price cap for capital city and regional centres can access both the federal scheme and the state grant.

You're not locked into a fully variable loan to access either scheme. A split loan structure with a fixed portion and a variable portion with offset is permitted under both programs, provided the participating lender offers that product. Not all lenders on the 5% Deposit Scheme panel offer the same loan features. Some allow splits and offsets. Others don't.

When you're comparing participating lenders, confirm whether the loan product supports a split structure and whether the variable portion includes a linked offset account at no additional cost. Some lenders charge an annual fee for offset access. Others don't. That annual fee can be $200 to $400 per year, which adds up over a 30-year loan term.

Splitting Your Loan Needs to Happen at Settlement

Most lenders require you to nominate the split structure before settlement. You can't settle on a fully fixed loan and then ask to convert part of it to variable with offset a few months later without refinancing or restructuring the loan, which may attract discharge or establishment fees.

Decide your preferred split ratio during the home loan application stage. Your broker can model different scenarios based on your savings pattern, income stability, and tolerance for rate movement. A 50/50 split is common, but 60/40 or 70/30 splits are equally valid depending on your priorities. If you want maximum rate protection, you might fix 70% or 80% and leave the remainder variable. If you want maximum flexibility and expect to build offset savings quickly, you might fix 40% or 50% and leave the rest variable with offset.

You're not stuck with the split forever. When the fixed term ends, you can refix the same portion, refix a different portion, or let the entire loan roll to variable. That decision happens at the end of the fixed term, not during it.

Most First Home Buyers Underestimate How Much Offset Saves Over Time

An offset account doesn't reduce your minimum repayment. It reduces the interest component of each repayment, which means more of your repayment goes toward reducing the principal balance. Over time, you pay the loan down faster without increasing your repayment amount.

You can use a mortgage repayment calculator to model the difference. The calculator won't show offset savings directly, but you can approximate the effect by reducing the loan balance by your expected average offset balance and comparing the results.

The benefit compounds if you're disciplined about keeping funds in the offset rather than spending them. Buyers who deposit their salary into the offset and pay all expenses from that account still benefit from the daily interest reduction, even if the balance fluctuates throughout the month. The offset calculation is done daily, so even holding an extra $5,000 in the account for two weeks out of every month reduces your interest compared to holding it in a separate savings account.
