Searches for "fixed rate" are up 250% year on year, according to CBA data from March 2026. Yet fewer than 5% of Australian mortgages are actually fixed. That gap — hundreds of thousands of borrowers looking but not locking — is where you probably sit right now.
The fixed vs variable rate home loan question in 2026 isn't about predicting the RBA. It's about what a wrong guess would cost your household, and whether you can wear it.
Three cash rate hikes in four months changed the mood. The RBA lifted the cash rate in February, March and May 2026, taking it to 4.35%, then held in June. The next decision lands on Tuesday 11 August 2026, and the banks disagree about what comes after it: one big-four bank forecasts two more hikes to a 4.85% peak, while CBA, NAB and ANZ all believe the peak has been reached and expect cuts from 2027. We unpacked that split in our guide to fixing your rate in 2026.
Rising-rate cycles punish complacency and reward preparation. Auction clearance rates are sitting in the low 40s, competition has thinned, and borrowers who structure their debt well now hold more negotiating power than they've had in years. This is the window to get the structure right.
Why is everyone suddenly googling "fixed rate"?
Because the pain is specific. Three hikes added roughly $315 a month to repayments on a typical $650,000 variable loan. When your repayment moves three times in four months, certainty starts to look like a product worth paying for, and a 250% jump in fixed-rate searches is exactly what that looks like.
Follow the chain one step further, though. By the time borrowers rush toward fixed rates, lenders have repriced them. Fixed rates are set off funding markets, not the cash rate, and we've watched a two-year fixed rate get repriced the Friday before an RBA meeting while borrowers waited for an announcement that no longer mattered. The upshot: today's fixed rates already carry the forecast hikes at least partly priced in. You're not buying tomorrow's rates at today's prices. You're buying certainty, at a premium.
The fact that under 5% of Australian mortgages are fixed tells you something too. Aussies prize offset accounts, extra repayments and the freedom to refinance on a whim. Fixing restricts all three, which is why so many of us research the fix and then keep floating.
What does fixing actually buy you, and what does it cost?
It buys one thing: a repayment that cannot move for the term. For a household budgeting around childcare fees, a parental-leave year or a single income, that certainty can be worth real money. You know the number. It stays the number.
Fixing isn't a bet that rates will rise. It's insurance. And insurance has a premium.
The costs sit lower in the fine print than the benefit does:
- A higher starting rate. In a hiking cycle, fixed rates typically sit above variable, because the market has priced the expected hikes in before you arrive.
- Capped extra repayments. Many fixed loans limit extra repayments to around $10,000 a year. Some allow less. Aggressive savers hit that ceiling fast.
- Usually no full offset. Most fixed loans won't attach a 100% offset account. If you hold serious savings against your loan, that flexibility has a dollar value; our guide to offset vs redraw puts numbers on it.
- Break costs. Sell, refinance or repay too quickly during the term and the exit fee can run into five figures. We've explained how lenders calculate them in break costs on fixed loans.
None of these are reasons not to fix. They're the price tag on the certainty, and the price tag deserves the same attention as the rate.
Where does variable earn its keep?
Flexibility, mostly. Unlimited extra repayments. A full offset account working against your balance from day one. No break costs if you sell next spring or refinance to a sharper deal in a year. And if CBA, NAB and ANZ are right about cuts arriving from 2027, variable borrowers ride them down without signing a single form, while fixed borrowers watch from the sidelines until their term matures.
The risk is the other fork in the road. If the 4.85% peak arrives, that $650,000 variable loan climbs another $210 or so a month on top of the $315 the 2026 hikes already added. Variable suits households that can absorb that and keep sleeping. It punishes budgets already at their ceiling.
Fixed vs variable rate home loan 2026: same couple, two paths
Steph and Dan are settling a $650,000 loan over 30 years in Greenslopes, on Brisbane's southside. For illustration, say their variable rate is 6.24% and the two-year fixed on offer is 6.49%. (Illustrative rates only, as at July 2026, not offers from any lender. The advertised rate isn't the full story either; the comparison rate folds in fees, and it's the number to check.)
Path A — they fix for two years at 6.49%. Repayments lock at about $4,102 a month. Total over the term: roughly $98,450, whatever the RBA does on 11 August or any meeting after it.
Path B — they stay variable at 6.24%. Repayments start at about $4,002 a month, then follow the cycle wherever it goes.
| Scenario over the 2 years | Path A: Fixed | Path B: Variable | Better off |
|---|---|---|---|
| Westpac is right: two more hikes to 4.85% by late 2026 | ~$98,450 | ~$99,900 | Fixed, by ~$1,450 |
| Big-bank consensus: hold through 2026, cuts through 2027 | ~$98,450 | ~$94,150 | Variable, by ~$4,300 |
Look at the shape of the table, not just the winners. Fixing costs Steph and Dan about $100 a month upfront and shrinks their range of outcomes to zero. Staying variable spans a roughly $5,700 gap between best and worst case. Neither path is free. One pays a known premium; the other carries an unknown range. Which of those your household can live with is the real decision.
Based on typical scenarios. Individual outcomes vary.
Is a split loan the each-way bet?
Often, yes. Splitting, say, 60% fixed and 40% variable locks certainty over most of the repayment while keeping a full offset and unlimited extra repayments on the variable slice. Cuts help part of the loan. Hikes hurt only part of it.
The right ratio follows your savings pattern, not a rule of thumb. A couple holding $80,000 in an offset wants a bigger variable portion so those savings keep working; a couple holding $5,000 and prizing a predictable repayment can push the fixed share higher.
Whichever structure you choose, the decision doesn't end at settlement. Wity Pulse monitors your loan against the market from settlement onwards, so when your fixed term nears maturity or your variable rate drifts above what new borrowers are paying, you hear about it before it quietly costs you a year of overpayment.
How do you decide before 11 August?
Four questions do most of the work:
- Stress-test your budget at +0.50%. If two more hikes would break it, certainty is worth its premium. Fix some or most of the loan.
- Check your three-year horizon. Planning to sell, upgrade or refinance inside the term? Break costs turn fixing into expensive insurance.
- Count your offset savings. More than about $30,000 sitting against the loan tips the maths toward keeping a healthy variable split.
- Look at what you're paying now. If your current variable rate sits well above what lenders offer new borrowers, the cheapest move may be neither fixing nor waiting, but refinancing to a sharper rate before the next decision lands.
And if you're one of the borrowers whose fixed term ends this year, the clock matters more again: our guide to what to do when your fixed rate expires covers the revert-rate trap.
