After three interest rate cuts in 2025, many borrowers were hoping the pressure had eased. But the Reserve Bank of Australia has since reversed course, lifting the cash rate again in 2026. For borrowers with an existing home loan, or those looking to buy, this has brought the fixed versus variable rate question back into focus. Fixing your rate can offer certainty, but it also involves trade-offs that are worth understanding before making a decision.

Here are three things to think about before deciding which option might suit your situation.

Fixed rates offer certainty, but at a cost

A fixed rate loan locks in your interest rate for a set period, typically between one and five years. During that time, your repayments stay the same regardless of what the RBA does with the cash rate. For borrowers who value predictability and want to budget with confidence, this can be beneficial.

However, fixed rates are generally priced with future rate movements already factored in. When lenders expect rates to rise, fixed rates often move ahead of the cash rate, meaning you may be paying a premium for that certainty from day one. It’s also worth noting that fixed-rate loans typically come with restrictions. Most limit how much extra you can repay during the fixed period, and breaking the loan early can trigger significant break costs.

Variable rates move with the market - in both directions

Variable rate loans move up or down in line with changes to the cash rate and lender funding costs. When the RBA cuts rates, variable borrowers typically benefit quickly. But when rates rise, repayments increase too. The trade-off for accepting that uncertainty is flexibility.

Variable rate loans generally allow unlimited extra repayments, access to offset accounts, and the ability to refinance without penalty if a better deal becomes available. For borrowers who want to pay down their loan faster or keep their options open, variable rate loans often provide more room to do so.

Splitting your loan is an option worth considering

Many borrowers feel pressure to choose between fixed and variable, but a split loan allows you to do both. With a split loan, a portion of the balance is fixed, and the remainder sits on a variable rate. This approach can offer a degree of repayment certainty on the fixed portion while retaining some of the flexibility of a variable loan, including the ability to make additional repayments and use an offset account on the variable portion.

 The split that suits you will depend on your financial situation, your outlook on rates, and how much flexibility you need. There’s no single right answer, and the best mix will differ from borrower to borrower.
