With the Reserve Bank holding the cash rate at 4.35% since its May 2026 increase, many borrowers are asking the same question: should I lock in a fixed rate now or ride the variable wave? There’s no one-size-fits-all answer, but comparing the numbers can help you see which choice aligns with your budget and peace of mind.
What the Numbers Say
Let’s ground the comparison in data. According to the RBA’s latest lenders’ rates for May 2026, the average new owner-occupier principal-and-interest home loan carried an interest rate of 6.15% per annum. That figure blends both fixed and variable loans, so actual rates will differ depending on the product you choose.
The official cash rate has been trending upward. After three consecutive 0.25 percentage point hikes in February, March and May 2026, the RBA left the rate unchanged in June at 4.35%. While no one can predict future moves, this tightening cycle matters for your decision: variable rates typically move with the cash rate, whereas fixed rates lock in today’s pricing for a set period.
Fixed Rate: Certainty with Limits
A fixed rate gives you the same repayment each month for the fixed term, often two or three years. MoneySmart notes that this makes budgeting simpler and can mean fewer loan features, which may lower costs. On the flip side, you won’t benefit if rates fall, and breaking a fixed contract early can trigger a break fee. Extra repayments may also be restricted.
Scenario – Ben fixes his $500,000 loan at 5.89% for two years. His monthly repayment is $2,993. Even if the cash rate rises further, his repayment stays put. But if rates drop, he’s locked in at the higher rate unless he’s willing to pay break costs.
Variable Rate: Flexibility with Uncertainty
For many borrowers, the 6.15% average new owner-occupier rate is a starting point for a variable product. Variable loans mirror market moves, so your repayment can rise or fall. MoneySmart highlights that you usually get more features—like offset accounts and free extra repayments—and it’s often easier to refinance later. The trade-off is a budget that can shift with each RBA announcement.
Scenario – Priya takes the same $500,000 loan on a variable rate of 6.15%. Her repayment starts at $3,049. If the cash rate climbs by another 0.25%, her rate could move to 6.40%, lifting her repayment to $3,130. If rates ease, she pockets the savings. She also parks $20,000 in her offset, effectively paying interest on only $480,000, which trims her interest cost each month.
A Split Loan: The Best of Both?
If you’re torn, a split loan lets you fix part of your balance and keep the rest variable. You might fix 50% to lock in certainty on half your debt, while the other half benefits from offset and extra repayment flexibility.
What to Compare Beyond the Rate
MoneySmart stresses that the interest rate is just one piece. Look at the comparison rate—a single figure that bundles the interest rate with most fees. Also check application fees, ongoing service fees, and the real value of loan features. An offset account sounds great, but if you can only keep a low balance, it may not justify the extra cost.
