In 2026, the RBA is widely expected to cut rates further. That changes the fixed vs variable calculus significantly — and means the choice you make in the next few months could save or cost you tens of thousands of dollars over the next five years.

What Fixed and Variable Actually Mean
Fixed rate: Your interest rate is locked for a set period — typically 1, 2, 3, or 5 years. Your repayments stay the same for that term regardless of what the RBA does. When the fixed term expires, you roll onto the lender's variable rate (usually higher than current market rates unless you proactively review).
Variable rate: Your rate moves with the market. When the RBA cuts, your repayments eventually drop. When the RBA raises, they go up. Variable loans offer more flexibility — offset accounts, unlimited extra repayments, and the ability to refinance without break costs.
The 2026 Rate Outlook
Nobody can say for certain where rates go next, and market expectations change often. That has two important implications for the fixed vs variable decision:
- Variable rates can fall or rise. Fixing now means locking in at current rates and potentially missing any cuts, while staying variable leaves you exposed to rises
- Fixed rates already reflect market expectations. Lenders price fixed terms off their view of future rates, so a fixed rate is not automatically a bargain or a bad deal. Compare it with the variable rate on the day
The practical implication: fixing for 5 years right now means betting that variable rates will average higher than today's fixed rate for the next 5 years. That is a bet on the future, and nobody can be sure how it turns out.

What Happens When Your Fixed Rate Expires
This is the most important scenario in 2026. Hundreds of thousands of Australian borrowers who fixed in 2020–2022 at historically low rates are rolling off onto variable rates that are 2–3% higher. If this is you:
- Don't wait for rollover to happen. Contact your broker 90–120 days before expiry. By then you'll have had time to research and lodge an application if switching
- Get a loyalty rate review from your current lender first. Ask them what rate they'll offer you post-rollover. Compare this against what a new lender will offer for a refinance
- Understand the rate comparison trap. Your lender's post-rollover variable rate is often much higher than their rate for new customers. This gap is your negotiating leverage
- Factor in break-even for switching. Use our refinance calculator to confirm that switch costs are recovered within a reasonable timeframe
Who Should Fix Right Now
Despite the general advice to stay variable in a cutting environment, fixing makes sense for specific profiles:
- Borrowers at maximum serviceability. If your repayments at the current rate are stretching your budget, fixing provides certainty that a potential RBA hold (or shock rise) won't push you into difficulty
- Buyers who need to budget precisely. First home buyers or upgraders who have carefully modelled their finances with a specific repayment in mind benefit from the certainty of fixing for 1–2 years while they settle in
- Borrowers unlikely to refinance or sell for 2+ years. If you're confident you'll hold the property and the loan for the fixed period, break cost risk is eliminated
Break Cost Traps You Need To Know About
Break costs are the single biggest reason borrowers regret fixing. They're also the most misunderstood part of a fixed home loan. Here's the plain-English version: when you fix, your lender hedges its own funding at the wholesale swap rate for your fixed term. If you exit early and wholesale rates have fallen, the lender is sitting on a loss — and they pass that loss to you as a break cost.
When rates are falling, this matters a lot. Break costs can be significant, especially on longer fixed terms. Common triggers:
- Selling the property before the fixed term ends — even if you plan to buy another one, portability isn't automatic across all lenders
- Refinancing to a cheaper lender because rates have dropped — the saving on paper vanishes once break costs are added
- Receiving a windfall (inheritance, bonus, equity release) and wanting to pay down more than the annual cap allows
- Splitting with a partner and needing to refinance into one name — this may be treated as a new loan by some lenders
Before fixing, model what happens if your life changes. If there's any realistic chance of selling, moving, or refinancing in the next 2–3 years, a shorter fix (1 year) or variable is usually safer than a 3–5 year fix.
When Fixing Actually Makes Sense In 2026
We're not anti-fixed. There are specific situations in 2026 where a short fix is the smart play — just not for the reasons most people assume:
- You're on a tight serviceability buffer. If a 0.5% jump in your rate would stretch your budget, locking in for 1–2 years removes that risk while the RBA cycle plays out
- You're a self-employed borrower with lumpy income. Fixed repayments make BAS planning easier — you know exactly what the mortgage costs each quarter
- You've just settled and don't want surprises. New home ownership comes with enough shocks (rates, strata, repairs). A 1–2 year fix gives you a stable base to find your footing
- You're an investor with multiple properties. Fixing one loan while the rest stay variable spreads cash-flow risk across the portfolio
- Short fixed rates are below variable. Fixed and variable pricing varies by lender and over time. If a short fixed rate is priced below variable, it may be worth considering. Ask for a written quote
Why Split Loans Are The Most Popular Choice In 2026
Split loans — part fixed, part variable — are a common choice for borrowers who want some certainty and some flexibility. The reason is simple: they hedge the decision instead of forcing it.
A typical structure looks like this: 50% of the loan sits in a 1 or 2 year fixed portion for repayment certainty. The other 50% stays variable, usually with an offset account so you can park savings against it. Advantages:
- Half your repayment is locked — budgeting is easier, and a rate shock only hits the variable half
- You keep offset benefits on the variable side — every dollar in offset still reduces interest
- Break costs are halved if you need to refinance, because only the fixed portion attracts them
- You participate in rate cuts on the variable half instead of missing them entirely
Splits don't have to be 50/50. If you have a specific "safe" repayment number in mind, we can reverse-engineer the fixed portion to match it. Run the numbers in our home loan repayment calculators or ask a broker to model a few splits for your loan size.
What If You Have Credit Issues Or A Specialist Lender?
Fixed-vs-variable thinking changes when you're not on prime pricing. If you're with a non-bank or specialist lender because of credit history, income type, or deposit size, your rates may already be higher than mainstream advertised rates — and the gap between fixed and variable options can be smaller.
Our usual advice for specialist borrowers:
- Stay variable for the first 12–24 months. The real win is cleaning up your file (paid defaults ageing, 12 months of clean conduct) and then refinancing to a mainstream lender at a far better rate — fixing locks you in and makes that move expensive
- Keep the exit strategy intact. Variable + no break costs means you can refinance the day your file qualifies for prime pricing
- If you're worried about budget, use a short 1-year fix rather than 3+ years, so you still have an exit window before your file qualifies for a cheaper loan
If you're not sure where you sit, our bad credit home loan guide walks through how specialist lenders price risk and a possible path back to mainstream pricing.
Frequently Asked Questions
Nobody can be sure where rates go in 2026. Staying variable (or using a split loan) is generally the more flexible option, while a fixed rate gives repayment certainty if that is your priority. Which suits you depends on your budget and plans, so a broker can compare your options.
You roll onto the lender's standard variable rate — which is typically much higher than what you'd get as a new customer. Review your loan 90–120 days before expiry: either get your current lender to match the market, or refinance to a more competitive option.
Most lenders allow up to $10,000–$20,000 in extra repayments per year on fixed loans. Exceeding this cap can trigger fees. Variable loans have no cap. If you plan to make significant extra repayments from bonuses or income windfalls, variable gives you more flexibility.
Break costs apply when you exit fixed early — by refinancing, selling, or exceeding the extra repayment cap. They're based on the difference between your fixed rate and current wholesale rates × balance × remaining term. In a falling rate environment, break costs can be substantial. Always get a written estimate before exiting.
A split divides your loan — part fixed for certainty, part variable for flexibility. No standard split ratio — your broker can structure it to match your cash flow needs and risk appetite. Popular in uncertain rate environments where you want some protection but don't want to miss potential rate cuts entirely.
Sometimes, but not often. A longer fixed term can lock in a rate above where variable ends up and carries break-cost risk if your circumstances change. It may suit you if you have a tight budget, are confident you won't move or refinance for the full term, and the fixed rate on offer is meaningfully below variable. Even then, a shorter fix or a split may be worth comparing.
Some lenders offer a rate lock service, usually for a fee. Fees, lock periods and conditions vary by lender, so ask for a written quote. A lock can protect you if rates move against you before settlement, which may be worth considering on larger loans.
It doesn't stop you refinancing, but it adds a cost. Any time you exit a fixed loan mid-term — whether to refinance, sell, or restructure — break costs apply. If a refinance opportunity comes up during your fixed term, ask your current lender for a written break-cost quote and run the maths before switching. In a falling rate environment, break costs can reduce or wipe out the saving.
