Most first home buyers overthink this one. The fixed vs variable home loan decision feels huge, but both will get you into the house, and the cost difference over three to five years is usually smaller than people fear. The honest truth is that whether you pick a fixed or variable home loan, the best option for you is the one that lets you sleep at night.
So before we get into rates and break costs and offset accounts, remember that. This is a decision you can get "wrong" and still be completely fine. There's no universally right answer. It comes down to your budget, your savings, how you feel about uncertainty, and a bit of a guess about where rates go next.
Updated 15 June 2026 — the day before the RBA's June decision. Here's the current backdrop, because it shapes the choice. The RBA cash rate sits at 4.35% after the 5 May 2026 hike (the third 25 basis point increase of the 2026 cycle, taking the rate back to its November 2023 peak). The market is now split on what happens next. Most economists expect a pause on 16 June, and several big lenders have walked back their rate-rise calls — NAB recently dropped its hike forecast and says the next move is more likely down, while CBA is tipping a hold. Nobody can promise where rates land, so treat any forecast (including the RBA's own May assumption that the cash rate could reach 4.7% by year-end) as exactly that: an assumption, not a guarantee. For the deeper rate picture, see our interest rate forecast for Australia and our guide to home loan interest rates.
The short answer
If you want the verdict before the detail, here it is. Choosing between a fixed or variable home loan really comes down to three quick reads on your own situation:
- Choose fixed if your budget is tight and certainty matters more than anything. You want to know your repayment to the dollar, and you're not expecting big lump sums or a move any time soon.
- Choose variable if you've got savings that could sit in an offset account, you want the freedom to make extra repayments or refinance without penalty, and you can stomach your repayment moving around.
- Choose a split loan if you're a first home buyer who genuinely can't decide — and most can't. A split gives you certainty on one part and offset flexibility on the other, so you're hedged whichever way rates go.
For a lot of first home buyers, that last option is the quiet winner. The rest of this guide explains why, with real dollar examples you won't find on a bank's page.
Fixed vs variable at a glance
In one line: a fixed rate locks your repayment for a set term, a variable rate moves with the market and unlocks an offset account, and a split loan gives you some of each. Here's how the three structures stack up side by side.
| Feature | Fixed | Variable | Split |
|---|---|---|---|
| Rate certainty | Locked for 1–5 years | Moves with the market | Half certain, half flexible |
| Extra repayments | Usually capped (often $10k–$20k/yr) | Unlimited | Unlimited on the variable part |
| Offset access | Rarely (sometimes partial) | Yes | Yes, on the variable part |
| Break costs if you exit early | Possible, and unpredictable | None | Only on the fixed part |
| Benefits if rates fall | No — you're locked in | Yes | Partly |
| Best for | Tight budgets, certainty seekers | Savers, flexibility seekers | First home buyers hedging both ways |
Fixed or variable home loan — what's the difference?
Strip out the jargon and the fixed or variable home loan decision is pretty simple.
A fixed rate is locked in for a set period — usually 1, 2, 3 or 5 years. Whatever the RBA or the wider economy does in that window, your repayment doesn't budge. When the fixed period ends, the loan automatically reverts to the lender's variable rate (which is usually higher), and you can refix, stay variable, or refinance somewhere else.
A variable rate moves up and down with the market. When the RBA changes the cash rate, most lenders adjust, though not always by the full amount and not always straight away. Your repayment can rise or fall at any time.
In Australia, the vast majority of mortgages are variable rather than fixed, and fixed lending as a share of new loans has fallen to record lows in recent years on the RBA's figures. It wasn't always this way. During the ultra-low-rate stretch of 2020–2021, a lot of borrowers locked in cheap fixed rates. When those terms rolled off in 2023–2024 (the so-called "fixed rate cliff"), millions snapped back to far higher variable rates almost overnight. That shock is still shaping how a whole generation of buyers feels about fixing.
Where rates sit as of June 2026
Rates move week to week, so treat the figures below as a snapshot, not gospel, and always check the live numbers before you commit. As of June 2026, here's roughly where owner-occupier loans with principal and interest repayments sit, from the sharpest advertised rates up to typical bank pricing:
| Loan type | Indicative range (June 2026) |
|---|---|
| Variable (with offset) | around 5.69%–6.64% |
| 1-year fixed | around 6.09%–6.59% |
| 2-year fixed | around 6.09%–6.49% |
| 3-year fixed | around 6.09%–6.49% |
| 5-year fixed | around 6.19%–6.69% |
Figures are indicative ranges triangulated from comparison sites such as Canstar in June 2026, not lender-by-lender quotes. The sharpest advertised rates sit well below big-four standard variable rates, which are still closer to the high 6s. The gap between lenders is large, which is exactly why a mortgage broker who compares 30-plus lenders can be worth so much. Even 0.3% off your rate on a $500,000 loan is worth around $30,000–$45,000 over 30 years.

Fixed rate home loans — pros and cons
The case for fixing
- Certainty. You know your repayment to the dollar for the next 1–5 years.
- Protection if rates rise. If the RBA pushes rates up during your term, you're shielded.
- Simple budgeting. Fixed repayments mean you don't need to keep a buffer for surprise increases.
Certainty is the number one reason people fix, and it's a good reason, especially if you're stretching to get in. No stress when the RBA makes an announcement, no recalculating the budget. And the protection is real money: if rates climbed 0.5% over two years, a borrower who'd fixed would dodge roughly $1,900 a year in extra repayments on a $500,000 loan.
The downsides of fixing
- Break costs. Exit early and the bill can be ugly.
- Capped extra repayments. Often limited to $10,000–$20,000 a year (it varies by lender).
- Usually no offset. Your savings sit idle instead of working against your loan.
- You miss rate cuts. If rates fall, you're locked in while variable borrowers pay less.
Break costs are the big one. If you sell, refinance, or repay early during the fixed term, the lender can charge a fee based on the gap between your fixed rate and current wholesale rates, multiplied by your balance and the time left. It's unpredictable, anywhere from a few hundred dollars to $20,000-plus in extreme cases, and it can make selling or refinancing your home loan painfully expensive. The capped repayments and no-offset limits matter most if you're someone who likes to throw spare cash at the loan; if that's you, fixing the whole thing can cost you the offset savings we cover below.
Variable rate home loans — pros and cons
The case for variable
- Flexibility. Unlimited extra repayments, offset access, redraw, and you can switch lenders without break costs.
- Offset account access. Arguably the single biggest advantage. It can save tens of thousands over the life of the loan.
- No break costs. Sell, refinance or repay any time, no penalty.
- You benefit from rate cuts. When the RBA drops the cash rate, your repayment usually follows.
Flexibility is why most Australians end up variable. Life changes. A new job in another city, a relationship shift, or simply a sharper rate down the road, and a variable loan doesn't punish you for adapting. The offset account is often what tips the decision; we'll show you the dollars shortly. One caveat on rate cuts: not every lender passes them on in full, which is another reason a broker who keeps an eye on your rate is worth having.
The downsides of variable
- Repayment uncertainty. Your repayment can rise at any time.
- Harder to budget. You need a buffer for potential increases.
- Lender discretion. Variable rates aren't tied directly to the RBA — lenders can move them on their own.
A 0.25% rise on a $500,000 loan adds around $75–$80 a month. A run of consecutive rises, like 2022–2023, can add $500-plus a month, which is genuinely stressful on a tight first-home-buyer budget. The reassuring part: lenders are required to assess whether you can repay at 3% above your actual rate (APRA's serviceability buffer, kept in place through 2026), so in theory you've already been stress-tested for higher repayments. You can see roughly where you'd land using our borrowing power calculator. Still, theory and a real higher repayment landing in your account are two different feelings.
Split home loans — the first-home-buyer middle ground
A split loan divides your mortgage into two portions: one fixed, one variable. You get a foot in both camps — certainty on part of your repayments, flexibility on the rest. It's the option we most often see make sense for first home buyers, precisely because it takes the pressure off getting the call exactly right.
How a split loan works
You choose the ratio. Common splits are 50/50, 60/40 (more fixed for certainty), or 40/60 (more variable for flexibility). Each portion has its own rate, and you make a separate repayment on each. Here's a rough worked example on a $500,000 loan at June 2026 rates:
| Portion | Amount | Rate | Monthly repayment |
|---|---|---|---|
| Fixed (3 years) | $300,000 | 6.09% | around $1,816 |
| Variable (with offset) | $200,000 | 6.19% | around $1,224 |
| Total | $500,000 | around $3,040 |
In this example the $300,000 fixed portion is locked at 6.09% for three years — that repayment won't move. The $200,000 variable portion comes with an offset account, where you can park savings and make extra repayments without restriction. (These are illustrative figures to show the method; your actual rates and repayments will differ.)
Split loan pros and cons for first home buyers
The appeal of a split is that it hedges your bet. If rates rise, the fixed portion shields you from the full hit. If rates fall, the variable portion benefits. You keep offset access on the variable side, so your savings still do some work. And if you need to refinance, break costs only apply to the fixed portion, not the whole loan. The trade-off is that you also only get half of each upside — you're not fully protected from rises and you don't fully cash in on cuts. For a first-timer who'd rather not bet the house on a rate forecast, that's usually a fair deal.
Most major lenders offer split loans, and the ratio can typically be reset when the fixed term ends — refix, go fully variable, or split again at a different mix. Ask your broker what split makes sense for your numbers.
What is an offset account and how does it save money?
An offset account is a savings or transaction account linked to your variable home loan. The balance in it is subtracted from your loan balance when the lender works out interest. You're not earning interest on the offset money — you're avoiding paying interest on that slice of your loan, which is actually better, because it's completely tax-free.
How it works in practice
Say your loan is $500,000 and you keep $40,000 in your offset. You only pay interest on $460,000. At 6.19%, that's roughly $2,476 a year you're not handing the bank — money that goes to your principal instead.
Over a 30-year loan, keeping an average of $40,000 in offset saves around $73,000 in total interest and clears the loan about three years early. Push that average to $80,000 and you're looking at savings closer to $120,000 and around five years off the term.
Why an offset beats a savings account
A regular savings account might pay around 4.5%–5.5%, but the headline rate often drops to a low base if you miss the monthly conditions — and you pay tax on whatever interest you do earn, at your marginal rate. For most home buyers that's the 30% bracket ($45,001–$135,000 of taxable income) or 37% above that. After tax, a 5% savings rate is really worth about 3.15%–3.5% in your pocket.
An offset, by contrast, effectively earns you your full home loan rate — say 6.19% — with zero tax, because you're reducing interest you'd otherwise pay rather than earning income. ASIC's MoneySmart explains that offset accounts can reduce the interest you pay and help you pay off your loan sooner, and it's why many people pick variable over a lower fixed rate. The maths favours the offset.
How to actually use it
Treat it as your everyday account. Have your salary paid straight in, pay bills from it, and keep your emergency fund there. Every dollar sitting in the offset — even for a single day — reduces that day's interest, because most Australian lenders calculate interest daily. The more money flowing through and resting in it, the more you save. It's the single most powerful tool a variable borrower has.
Offset vs redraw — what's the difference?
A redraw facility lets you take back extra repayments you've already made. If you've been paying more than the minimum, the surplus sits inside the loan reducing your balance, and redraw lets you withdraw it again if you need it. It sounds similar to an offset, but the two behave quite differently.
| Feature | Offset account | Redraw facility |
|---|---|---|
| How it works | Separate account linked to the loan | Extra repayments stored in the loan itself |
| Access to funds | Instant — it's a bank account with a card | Usually 1–3 business days, may have limits |
| Tax treatment | No tax implications | Can create tax complications for investors |
| Available on fixed loans? | Rarely | Sometimes, with limits |
| Fees | Some lenders charge a monthly fee | Usually free |
| Best for | Everyday banking, emergency fund | Lump sums you might want back later |
For most owner-occupier first home buyers, an offset wins — it's more flexible, has no tax complications, and works like a normal bank account. Redraw is a handy backup, especially on products that don't offer offset (including many fixed loans).
One note for anyone who might one day rent the place out: if you ever convert your home to an investment property, keeping spare cash in an offset (rather than paying it down and using redraw) preserves the full tax-deductibility of your loan interest. It's a fiddly area, so check it with your accountant and broker before you decide.
How to decide — fixed, variable, or split?
Run the checklist below against your own situation.
Choose fixed if:
- You're on a tight budget and need absolute certainty on repayments
- You believe rates will rise meaningfully over the next 2–3 years
- You don't have savings that would benefit from an offset
- You plan to hold the property for the full fixed term without selling or refinancing
- You're not expecting lump sums (bonuses, inheritance) you'd want to put on the loan
Choose variable if:
- You want maximum flexibility — extra repayments, offset, no break costs
- You have savings that will work harder in an offset account
- You think rates may fall or hold steady
- You might sell, refinance or move within a few years
- You're comfortable with the chance of your repayment rising
Choose a split loan if:
- You want a balance of certainty and flexibility
- You're unsure which way rates are heading and want to hedge
- You have some savings for an offset but also want some repayment certainty
- This is your first mortgage and you'd rather not bet it all on one call
For most first home buyers, a split — say 50/50 or 60/40 in favour of variable — is a sensible starting point. You get the offset benefit on the variable side while shielding part of your repayment from rises, and you can always reset the ratio when the fixed term ends. The one thing we'd steer you away from is agonising over this in a vacuum. A good mortgage broker will model the scenarios with your real numbers — income, deposit, loan size, savings — and show you what each option actually costs, for free.

Frequently asked questions
Should I fix my home loan in 2026?
For most first home buyers, no — a split or variable usually wins, because the gap between fixed and variable rates is narrow and offset access is worth real money. If you value certainty above all and genuinely believe rates will keep rising, fixing part or all of your loan can make sense. But the majority of first-timers in 2026 are landing on variable or a split. A broker can model both with your exact numbers and show you the dollar difference.
What are fixed rate break costs?
Break costs are a fee your lender charges if you exit a fixed loan before the term ends — by selling, refinancing, or repaying in full. The lender calculates them from the difference between your fixed rate and the current wholesale market rate, multiplied by your balance and the time remaining. They can range from a few hundred dollars to $20,000-plus and are genuinely unpredictable, because they depend on market conditions on the day you break. Always ask your lender for a written break-cost estimate before committing to anything.
Is an offset account worth it?
Yes — for most borrowers it's the single most valuable feature in a home loan. Keep an average of $30,000–$50,000 in your offset and you can save $50,000–$100,000-plus in interest over a 30-year loan and pay it off three to five years early. The benefit is completely tax-free, because you're avoiding interest rather than earning it. Even if your lender charges a small monthly fee for offset access, the savings almost always dwarf the cost.
Can I switch from fixed to variable?
Yes, but switching during the fixed period can trigger break costs. Once your fixed term expires, the loan automatically reverts to the lender's variable rate, and from there you can stay variable, refix at current rates, move to a split, or refinance elsewhere with no penalty. If you want to switch mid-term, ask your lender for a break-cost estimate first — many borrowers find it cheaper to wait until the fixed term ends naturally, even when variable rates look more attractive right now.
Is it better to get a fixed or variable home loan in Australia?
It depends, but for most Australian first home buyers a split loan is the safest answer — it hedges you both ways. Fixed wins if certainty is your priority and you think rates will rise; variable wins if you have savings for an offset and value flexibility. Because nobody can reliably predict the RBA, splitting your loan means you don't have to be right about the rate forecast to come out fine.
What happens when my fixed rate ends?
When your fixed term expires, your loan automatically rolls onto the lender's standard variable rate — known as the "revert rate" — which is often higher than the sharp rates available elsewhere. This is the moment the "fixed rate cliff" caught so many borrowers in 2023–2024. It's also a free decision point: with no break costs at expiry, you can refix, stay variable, switch to a split, or refinance to a better deal. Set a reminder a couple of months before your term ends so you can shop around rather than drifting onto the revert rate by default.
Can I have an offset account on a fixed home loan?
Usually no — an offset is generally a variable-loan feature. Some lenders offer a partial offset on a fixed loan, but it's less common and can come at a higher rate or fee. If keeping your savings in an offset matters to you (and for most savers it should), that's a strong argument for going variable or, more commonly for first home buyers, splitting your loan so the variable portion carries the offset. ASIC's MoneySmart confirms offsets are typically tied to variable loans.
