Fixed vs variable: which home loan is right for you?
If you've ever sat across the table from a banker or broker and been asked "so, do you want fixed or variable?" and felt a wave of anxiety wash over you, you're not alone.
It sounds like a simple question. But the honest answer is that it depends on your situation, your personality, and what's happening in the economy at the time. There's no universally "right" answer, which is probably why the question trips so many people up.
This article breaks down exactly what each option means, the genuine trade-offs involved, and how to think about the decision in the current rate environment.
First, what's the actual difference?
Let's make sure we're on the same page.
Variable rate: Your interest rate moves up and down over the life of your loan, generally in line with decisions made by the Reserve Bank of Australia (RBA). When the RBA cuts the cash rate, your lender will typically (though not always) reduce your rate too. When the RBA hikes, your rate usually goes up. Your repayments change accordingly.
Fixed rate: You lock in an interest rate for a set period, usually one to five years. During that time, your repayments stay exactly the same regardless of what the RBA does. When the fixed term ends, your loan rolls onto your lender's variable rate.
That's the core distinction. Everything else flows from there.
The case for variable
Variable rate loans are by far the most popular choice in Australia. According to the Reserve Bank of Australia, around 98% of new owner-occupier loans are variable. There are good reasons for that.
You keep your flexibility
Variable loans typically come with features that fixed loans don't, or heavily restrict. Things like:
- Offset accounts: A transaction account linked to your loan where any money sitting in the account reduces the interest you're charged. If you have $30,000 in an offset account against a $600,000 loan, you're only paying interest on $570,000.
- Unlimited extra repayments: You can throw any extra money at your loan, bonuses, tax returns, inheritance, without penalty.
- Redraw facilities: If you've made extra repayments, you can pull that money back out if you need it.
- No break costs: If you want to refinance or pay off your loan early, there's no penalty. You can move whenever a better deal comes along.
You benefit when rates fall
When the RBA cuts the cash rate and lenders pass it on, your repayments drop. During 2025, the cash rate was cut three times. Borrowers on variable loans felt the benefit each time, while those locked into fixed rates did not.
The trade-off
The obvious downside is uncertainty. When rates rise, so do your repayments, sometimes significantly. A 0.25% rate increase adds around $90 to $100 per month to repayments on a typical $600,000 loan. That might not sound like much in isolation, but after several consecutive hikes, the cumulative impact on a household budget can be substantial.
The case for fixed
Fixing your rate is essentially buying certainty. You know exactly what you'll pay each month for the next one, two, three or five years, regardless of what the RBA decides.
Budget predictability
This is the big one. If you're stretching your finances to buy your first home, recently had a baby, are running a business with lumpy income, or simply sleep better knowing your mortgage repayment won't change, a fixed rate can be genuinely valuable.
There's also a psychological benefit that doesn't get talked about enough. Watching interest rates rise when you're on a variable loan is stressful. If fixing your rate means you stop refreshing the RBA website every month, that peace of mind has real value.
Protection against further hikes
Economists at three of Australia's big four banks are currently predicting the cash rate will rise at least once more in 2026. If those forecasts prove correct, locking in now could protect you from those additional increases for the duration of your fixed period.
The trade-offs
Fixed loans come with real limitations:
- Break costs can be significant. If you decide to refinance, sell, or pay off your loan during the fixed period, lenders can charge substantial "break fees", sometimes running into tens of thousands of dollars depending on how much rates have moved.
- Limited extra repayments. Most lenders cap the extra repayments you can make each year on a fixed loan (often around $10,000 annually). Above that, you may be charged a fee.
- No offset account (usually). Most fixed rate loans don't offer a fully functional offset account. This means you lose one of the most effective tools for reducing interest over the life of your loan.
- The "revert rate" sting. When your fixed term ends, your loan rolls onto your lender's standard variable rate, which is often one of their least competitive offerings. Many borrowers fix their rate, forget about it, and find themselves on an expensive rate when it expires. The lesson: always review before your fixed period ends.
What about a split loan?
A split loan lets you have both. A portion of your loan on a fixed rate and the remainder on variable. For example, you might fix 60% of your loan for two years while keeping 40% variable.
Around 9% of Australian borrowers are currently considering a split loan as a way to hedge their bets.
It's a sensible middle-ground option for people who want some budget certainty but don't want to give up their offset account or the ability to make extra repayments on the variable portion. The split doesn't have to be 50/50. You can adjust the ratio to suit your priorities.
So which is right for you?
Here's a straightforward way to think about it:
| Your situation | Consider |
|---|---|
| You want certainty and can live with the restrictions | Fixed |
| You want maximum flexibility and features | Variable |
| You want both, some certainty, some flexibility | Split |
| You're planning to sell or refinance in the next year or two | Variable (avoid break costs) |
| Rates are rising and you're worried about affordability | Fixed (to lock in before further hikes) |
| Rates are falling and you want to benefit | Variable |
| You regularly make large extra repayments | Variable |
The honest truth is this: no-one, not economists, not the banks, not the RBA itself, can predict with certainty where rates will go. A few months ago, most people believed interest rates would keep falling into 2026, but the opposite has happened. The best choice is less about trying to "win" on rates and more about choosing the structure that matches your financial situation and lets you sleep at night.
What does the current rate environment look like?
As of April 2026, the RBA cash rate sits at 4.10% after a hike in February, a reversal of the three cuts that happened throughout 2025. Competitive variable rates now start from around 5.08% for owner-occupiers, while fixed rates are generally sitting slightly higher for most lenders.
The general pattern right now is that variable rates are slightly more competitive than fixed at the headline level, which is unusual. Normally, the market "prices in" expected future hikes into fixed rates, making them higher than variable. When fixed rates are close to or below variable rates, it can be a signal that markets expect rates to eventually come down over the fixed period.
What does this mean for you? It's worth having the conversation with a broker rather than making the call alone.
Before you decide, check where you stand
Whether you're taking out a new loan or considering switching your current one from variable to fixed (or vice versa), the starting point is always the same: know your current rate and know what's available in the market.
If your existing variable rate is already uncompetitive, fixing it with your current lender might simply lock you into a bad deal for longer. Before making any changes to your loan structure, it's worth checking whether your overall rate, fixed or variable, is actually competitive.
If you're not getting a good deal, a mortgage broker can help you find a better structure and a better rate at the same time.
