Fixed vs Variable Home Loan Rates 2026 Australia
Fixed vs Variable Rates in 2026: What Should You Choose?
Nobody wants to get this decision wrong, and in March 2026, it feels harder than ever to get it right. The RBA has hiked the cash rate twice this year, in February to 3.85% and again in March to 4.10%. All four major banks are now forecasting another hike in May 2026, potentially taking the cash rate to 4.35%. In this environment, the question every borrower is asking is the same: Should I lock in a fixed rate now or stay variable and ride out what comes next? The answer depends on your situation, but there is a clear way to think through the decision. And at ASK Financials, we work through it with clients every week.
Where Rates Actually Sit Right Now
As of late March 2026, competitive variable home loan rates start from around 5.08% p.a. for owner-occupiers, with the average variable rate sitting around 6.45% across the market. Standard variable rates at the big four banks are higher. CBA's standard variable sits at 8.10%, though discounted rates for new customers vary depending on LVR and borrower profile. Fixed rates for 1–2 year terms are broadly in a similar or slightly higher range than discounted variables right now, because lenders have already priced in the expected upcoming hikes.
Australia's big four banks are predicting at least one more rate increase in 2026. That matters because it changes the calculus on fixing if rates are likely to keep rising; locking in today looks more attractive. If they plateau or fall, the variable wins.
The Case for Staying Variable
A variable rate isn't the risky choice it might seem when rates are rising. Here's what it actually gives you:
Offset account access — the most powerful feature of most variable loans. Every dollar sitting in your offset account reduces the interest you pay daily. On a $700,000 loan with $50,000 in offset, you're only paying interest on $650,000
Unlimited extra repayments — pay down your loan faster without restriction. Fixed loans typically cap additional repayments at $10,000–$30,000 per year
No break fees — if circumstances change, you sell, refinance, or rates drop, you're not locked in and facing a costly break fee
The rate may be competitive enough — with discounted variable rates starting around 5.08%, some borrowers are already on rates that compare well with available fixed options
The mortgage holders who plan to stay variable in 2026 are largely betting that the rate cycle is near its peak and that flexibility will be worth more than certainty over the next 12–24 months.

The Case for Fixing And When It Makes Sense
Fixing makes the most sense when two conditions align: rates are expected to keep rising, and you value certainty over flexibility. In March 2026, the first condition looks increasingly likely, but the second is personal.
What fixing a home loan rate actually gets you:
• Repayment certainty — you know exactly what you're paying each month, regardless of what the RBA does
• Protection against further hikes — if ANZ, CBA, NAB, and Westpac are all right about a May 2026 hike, fixing now could look smart by Q3
• Budget stability — particularly valuable for households where cash flow is tight and a further rate rise would create genuine stress
The trade-off: fixed loans lose the offset account in most cases, cap your extra repayments, and charge break fees if you exit early. And if rates drop, which no one is predicting right now but history shows can happen quickly, you're locked in above the market rate.

The Middle Ground: A Split Loan
For borrowers who want both certainty and flexibility, a split home loan is worth considering. Fix a portion, say 60–70%, for repayment certainty on the bulk of your debt, while keeping the remainder variable with an offset account and unlimited repayment flexibility. It's one of the most commonly recommended structures by mortgage brokers in the current environment, and it's exactly the kind of tailored approach ASK Financials builds for clients depending on their income, cash flow, and property plans.
How These Rate Changes Affect Your Borrowing Power
It's not just your repayments that change; every rate hike also compresses what you can borrow. The APRA 3% serviceability buffer means applications are assessed at your contract rate plus 3%. With variable rates around 6.45%, you're being stress-tested at 9.45%. On a $120,000 household income, that buffer alone reduces borrowing capacity by $80,000–$120,000 in comparison. This is the environment every new borrower and refinancer is navigating right now, and why lender selection and loan structure matter more than at any point in recent years.
FAQ: Should I fix my home loan rate now before the next RBA hike?
Answer: It depends on your cash flow, flexibility needs, and how long you plan to hold the loan. Fixed rates have already priced in some expected hikes, so you're not necessarily saving money. ASK Financials can model the fixed vs variable comparison for your specific loan amount and circumstances before you decide.
Final Thoughts
The fixed vs variable decision isn't just about picking the cheaper number. It's about matching your loan structure to your actual financial situation, your risk tolerance, and where you think rates are heading. In 2026, with two hikes already delivered and more potentially coming, getting that structure right from the start is genuinely important.
