Fixed vs variable home loan: what to consider in 2026

After the RBA reversed its 2025 rate cuts, the fixed vs variable question is back for Australian borrowers. Here's what to think through before you decide.

The Reserve Bank cut rates three times in 2025. Then it raised them again.

For borrowers who had settled into the expectation of falling repayments, that reversal in 2026 hit hard. And for anyone currently shopping for a home loan, or sitting on an existing one wondering whether to refinance, it has brought the fixed vs variable question back with some urgency.

There’s no universally right answer. A fixed rate home loan suits certain situations, a variable rate suits others, and a split loan sits somewhere in between. The decision comes down to your financial position, your plans for the property, and what you value in a loan structure.

How a fixed rate home loan works

A fixed rate home loan locks in your interest rate for a set period. In Australia, fixed terms typically run between one and five years, though some lenders offer terms outside that range. During the fixed period, your repayments don’t change regardless of what the RBA does with the cash rate.

That stability has real appeal for borrowers who want to budget with precision. If you’re servicing other debt, planning a renovation, or working on a tight monthly surplus, knowing your home loan repayments won’t shift for the next two years takes one variable out of the picture.

The catch: fixed rates aren’t a straight reflection of today’s cash rate. Lenders price fixed rates based on where they expect rates to be over the entire fixed term. When markets expect the cash rate to rise, fixed home loan rates typically move ahead of it. You might fix at a rate that feels reassuringly stable, but it may already include a premium for the uncertainty you’re removing.

There’s also the revert rate to consider. When the fixed term expires, most loans roll onto the lender’s standard variable rate unless you renegotiate or refinance. That standard variable rate is often higher than the competitive rates available elsewhere. Borrowers who set and forget often end up paying more than those who actively manage their loan at the end of a fixed term.

The real cost of fixing your rate

The interest rate is only part of the story with a fixed home loan. The structural restrictions attached to fixed rate products affect what you can do with your money and your loan.

Extra repayments are capped. Most fixed rate home loans limit how much extra you can pay above the minimum repayment during the fixed term. Depending on the lender and product, that cap typically sits somewhere between $10,000 and $30,000 per year. If you receive a windfall and want to put it against your mortgage, you may only be able to apply part of it. Paying above the limit can attract fees.

Offset accounts generally aren’t available. A standard offset account reduces the interest calculated on your loan balance. On a $550,000 loan with $60,000 sitting in an offset account, you pay interest on $490,000. This feature is typically only available on variable rate loans. Fix your rate and you lose that benefit for the duration of the term.

Break costs can be significant. If you exit a fixed rate loan before the term ends — whether to sell, refinance, or switch products — the lender will charge a break cost. These costs are calculated against wholesale market rates and the remaining term of the loan. When rates have fallen since you fixed, break costs can run into thousands of dollars. When rates have risen, they may be minimal. The problem is you can’t accurately predict the amount upfront.

The break cost risk is one reason fixed rate loans and short-term property plans often don’t mix well. If there’s a meaningful chance you’ll sell within the fixed period, the cost of exiting early could exceed any benefit from rate certainty.

How a variable rate home loan works

A variable rate home loan has a rate that changes over time. The primary driver is the RBA cash rate, though lenders also adjust rates based on their funding costs and competitive positioning. Your home loan repayments go up when rates rise and down when rates fall.

After the RBA cut rates during 2025, variable rate borrowers saw their minimum repayments decrease. After the subsequent rise in 2026, repayments increased. This is the core trade-off: you accept uncertainty in exchange for flexibility.

One thing many borrowers don’t fully account for: lenders exercise discretion when passing on rate changes. An RBA cut of 0.25% doesn’t automatically translate to a 0.25% reduction in your variable rate. Some lenders pass on cuts in full, others trim a few basis points. When rates rise, pass-through tends to be faster and more complete than when rates fall. Watching whether your lender reflects RBA movements in your rate is worth doing, particularly mid-cycle.

What you get with a variable home loan

Variable rate home loans typically include features that fixed loans don’t offer, and for many borrowers these features matter as much as the rate itself.

Offset accounts. An offset account linked to your variable home loan reduces the balance on which interest is calculated. Keeping $50,000 in an offset account against a $600,000 loan means you pay interest on $550,000. Over a 30-year term, the difference compounds. Borrowers who maintain consistent savings in an offset account can shave years off their loan term and reduce total interest paid, without making extra repayments.

Unlimited extra repayments. On most variable loans, you can pay as much as you like above the minimum, whenever you like. Commission payments, tax refunds, bonuses, inheritance — you can direct any surplus at the loan without penalty.

Redraw. Many variable loans include a redraw facility that lets you access any extra repayments you’ve made. If you’ve been paying extra and then need funds for something unexpected, you can pull that money back out. The loan balance resets accordingly.

Flexibility to refinance. Without a fixed term to break out of, switching to a different lender or product on a variable loan is generally straightforward. If a better deal comes onto the market, you can act on it. This flexibility also matters for borrowers whose financial situation changes, whether that means needing to restructure, consolidate, or access equity.

Fixed vs variable: the key differences

What is a split home loan?

A split loan divides your home loan into two portions. One portion sits on a fixed rate, the other on a variable rate. The split can be anything from 50/50 to 70/30 to 80/20, depending on what works for your situation.

The fixed portion gives you stable repayments on that share of the loan. The variable portion keeps the benefits: offset account access, unlimited extra repayments, and the freedom to refinance that portion if a better rate emerges.

Split home loans suit borrowers who don’t want to make an all-or-nothing bet. If rates rise substantially, the fixed portion acts as a buffer for part of your loan. If rates fall, you benefit on the variable portion. You won’t capture the full upside of either outcome, but you also won’t carry the full risk of being entirely on the wrong side of a rate move.

A simple example: if your loan is $700,000 and you split 50/50, $350,000 is fixed and $350,000 is variable. You can park savings in an offset account against the variable portion, make extra repayments on that portion, and have certainty on the fixed portion’s repayments throughout the term.

The proportion that makes sense depends on your loan size, how much flexibility you need, and how you use your surplus funds. A mortgage broker can run the numbers on different split scenarios to show what each means for your monthly repayments and total loan cost.

Factors worth thinking through before you decide

The fixed vs variable question involves more than a view on where rates are going. A few practical considerations tend to matter more.

Your repayment buffer. If you’re stretched at your current repayment level, a rate rise would put you in a difficult position. In that case, fixing a portion or all of your loan removes that risk for the fixed term. If you have comfortable headroom, the flexibility of a variable loan may serve you better than the certainty of a fixed rate.

How long you’re staying. If there’s a reasonable chance you’ll sell in the next two to three years, fixing your rate introduces break cost exposure that could wipe out any benefit from rate certainty. A variable loan or a short fixed term typically fits better with a shorter time horizon.

Whether you receive irregular income. Commission-based earners, business owners, and seasonal workers often have income that spikes at certain times of year. If you want to put income surpluses against your loan when they arrive, you need a product that allows it. That means variable, or the variable portion of a split.

How you use your savings. If you hold a meaningful balance in a transaction or savings account, an offset account can reduce your effective interest rate without you doing anything differently. That feature is generally only available on variable loans. Borrowers who don’t maintain a consistent savings buffer get less value from an offset account, and the flexibility argument for variable becomes less compelling.

Where fixed rates are positioned relative to variable rates. When fixed home loan rates sit well above current variable rates, the market is pricing in anticipated rate rises. When fixed and variable rates are close, or fixed rates are lower, lenders are pricing in more stability or potential cuts. Neither signal is definitive — markets get these things wrong — but it gives you a read on what’s already baked into the price of certainty.

Your tolerance for uncertainty. Financial analysis aside, some borrowers find rate movements stressful. If watching the RBA announcement and doing mental arithmetic about next month’s repayments isn’t how you want to spend your time, the psychological value of a fixed rate is real and worth something.

What’s changed in the current environment

The RBA’s rate-cutting cycle in 2025 moved quickly. Three cuts across the year brought the cash rate down from its 2024 peak, and variable rate borrowers benefited. Some borrowers who had been on fixed rates through 2024 and 2025 found themselves rolling off their fixed terms and onto variable rates that were lower than they expected — a reasonably positive outcome.

The 2026 rate rise changed the calculation. Borrowers on variable loans saw repayments increase. And for those shopping for a new loan or coming off a fixed term, the fixed vs variable decision suddenly has more riding on it than it did six months ago.

Fixed home loan rates for popular terms reflect the current uncertainty. They’re priced with anticipated rate movements already factored in. Whether that pricing turns out to be accurate depends on economic outcomes that no lender — and no forecaster — can reliably predict.

In this environment, comparing across lenders matters more than usual. The spread between the most competitive and least competitive rates on both fixed and variable products has widened, and the features attached to those rates differ considerably.

How a mortgage broker approaches this decision

A mortgage broker has access to a panel of lenders and can pull together a real comparison across fixed, variable, and split structures for your specific numbers. That means more than looking at a rate table — it means running your actual loan size, your income situation, and your plans through the products available to see what each option costs you over different time horizons.

For the fixed vs variable question, a broker can model what a rate rise of, say, 0.50% would mean for your variable repayments, whether fixing one portion of your loan would meaningfully change that exposure, and what break costs look like under different scenarios if you’re considering selling or refinancing before a fixed term ends.

A broker can also flag details that don’t show up in a comparison rate: how individual lenders handle rate changes, what the standard revert rate looks like at the end of a fixed term, which lenders’ offset accounts have strong features and low fees, and whether any lenders on the panel have fixed products that allow more generous extra repayments than others. Four reasons your home loan might be declined.

The decision doesn’t have to be the same for everyone, and the right structure for your neighbour with a similar loan size may not be right for you. Getting a comparison done for your specific situation is a more reliable basis for the decision than a general rule of thumb.
