Fixed vs Variable Home Loans in 2026: How Brisbane Borrowers Should Decide

Fixed or variable is one of the first decisions every borrower faces, and one of the most second-guessed. There is no universally right answer, only the right answer for your circumstances. Here is how to think it through without trying to predict the Reserve Bank.

What each option actually gives you

A variable rate moves with the market. When your lender changes its rates, usually in response to the Reserve Bank of Australia's cash rate decisions but not only then, your repayments change too. Variable loans generally come with the full toolkit: offset accounts, unlimited extra repayments, redraw and the freedom to refinance or sell without penalty.

A fixed rate locks your interest rate for a set term, typically one to five years. Your repayments stay the same for that term regardless of what the market does. In exchange, fixed loans usually restrict extra repayments to a small annual cap, rarely offer a full offset account, and charge break costs if you exit, refinance or sell before the term ends.

A split loan divides your balance into a fixed portion and a variable portion, in whatever proportion you choose. It is not a compromise so much as a hedge: part certainty, part flexibility.

The mistake most people make

Most borrowers approach this decision as a bet on where rates are heading. That is understandable, but it is the wrong frame for two reasons.

First, lenders price fixed rates using the same forecasts you are reading about. If the market expects rate cuts, fixed rates will already be set below variable rates to reflect that; if it expects rises, fixed rates will sit higher. You are not getting an edge by fixing when everyone expects cuts – you are paying for certainty at a price that already includes those expectations.

Second, forecasts are frequently wrong. Borrowers who fixed at the peak of the last cycle, and those who stayed variable through the fastest rate rises in decades, both had good reasons at the time. What separates a good decision from a bad one is not the outcome; it is whether the loan structure suited your life.

So instead of asking "where are rates going?", ask "what would hurt me more: repayments rising, or being locked in?"

Questions that actually decide it

How tight is your budget?

If a rise in repayments of a few hundred dollars a month would put real pressure on your household, certainty has genuine value, and fixing part or all of your loan makes sense even if it costs a little more. If you have plenty of buffer, you can afford to ride the variable rate and keep the flexibility.

Do you have (or expect) surplus cash?

An offset account is one of the most powerful features in Australian home lending: every dollar sitting in it reduces the interest you pay. If you hold significant savings, receive bonuses, or run a business through your accounts, a variable loan with an offset will often beat a fixed rate over the long run. Fixing all of your loan usually means giving that up.

Could your circumstances change during the term?

Selling, upgrading, separating, refinancing to release equity, or simply switching lenders because a better deal comes along, can all trigger break costs on a fixed loan. Break costs are calculated on the difference between your fixed rate and current market rates for the remaining term, and can run to thousands of dollars when rates have fallen. If there is a realistic chance you will need to move in the next few years, keep the fixed term short or the fixed portion small.

Are you buying, refinancing or building?

Construction loans are usually variable during the build. Refinancers often have the clearest picture of their spending and can choose a split with confidence. First home buyers frequently value the certainty of a fixed portion for the first couple of years while they adjust to ownership.

Why a split loan is so often the answer

A split of, say, half fixed and half variable gives you a predictable floor on your repayments while keeping an offset and unlimited extra repayments on the variable half. If rates rise, only part of your loan is exposed. If they fall, you still benefit on part of it. And if you need to sell, the break cost applies only to the fixed portion.

The proportions are up to you. Borrowers with strong savings habits often keep the larger share variable; households with tighter budgets often fix the larger share.

Practical details to check before you fix

• Rate lock. Fixed rates can change between your application and settlement. Many lenders offer a rate lock for a fee that holds the rate for a set period; decide whether it is worth it for your timeline.
• Extra repayment caps. Check the annual limit on your fixed portion, and whether unused allowance rolls over.
• What happens at expiry. Fixed loans roll to the lender's standard variable rate at the end of the term, which is often higher than what new customers are offered. Diarise the expiry date and review your loan a few months before.
• Offset on fixed. A small number of lenders offer a partial or full offset on fixed loans; if that feature matters to you, ask us which ones.

How we help you decide

We do not have a house view on rates and we will not pretend to. What we do is model your actual repayments under a few scenarios, compare the fixed, variable and split options across our lender panel, and show you the break-even points so you can see what you are paying for certainty. For existing borrowers, we also flag when a fixed term is about to expire so you are never left on a rollover rate by default.

If you are weighing up fixing, refinancing or restructuring, book a strategy call and we will walk through the numbers together.
