There has never been a more consequential time to get this decision right.
The Reserve Bank of Australia has raised the official cash rate three times already in 2026 — in February, March, and again in May — and the debate in every Australian household with a mortgage has sharpened from background noise into something urgent. Google searches for “fixed rate home loan” surged more than 250% in March compared to a year earlier. That tells you everything about the anxiety borrowers are feeling right now.
But here’s the thing: most of that anxiety is being channelled into the wrong question. Australians are asking “should I fix my rate?” when the better question is “what loan structure actually fits my life, my income, my plans, and my financial goals?”
The answer is almost never as simple as the headline rate suggests — and it’s rarely the same for any two borrowers.
This guide cuts through the noise. We’ll explain exactly how fixed and variable loans work in 2026, what the current rate environment means for each option, and give you a practical framework for deciding what’s right for your situation.
The Rate Environment in May 2026: What You’re Actually Deciding Into
Before we compare the two loan types, you need to understand the environment you’re making this decision in.
As of May 2026:
- The RBA cash rate now sits at 4.35% following the May rate decision — the third increase of the year
- Competitive variable rates for owner-occupiers start from approximately 5.08% p.a., with the market average around 6.3–6.45%
- Big four bank standard variable rates are considerably higher — CBA’s standard variable sits at 8.10%, though discounted rates for new customers vary based on LVR and borrower profile
- Fixed rates for 1–2 year terms are sitting at roughly similar levels to discounted variable rates — or slightly above — because lenders have already priced in the anticipated hikes
- Three of the four major banks currently have their fixed rates above their variable rates, which in mortgage market language is a signal that lenders expect rates to keep rising
This matters enormously for the fixed vs variable calculation. When a lender prices their fixed rate higher than their variable rate, they’re effectively telling you: “We think rates are going up. If you want certainty, you’ll pay for it.”
That’s the environment you’re in. Let’s now understand both options properly.
What Is a Fixed Rate Home Loan?
A fixed rate home loan locks your interest rate — and therefore your repayments — at a set level for an agreed period. In Australia, fixed terms typically run from 1 to 5 years. At the end of the fixed period, the loan automatically reverts to the lender’s standard variable rate unless you refinance or fix again.
What you gain is certainty. Your repayment on day one is identical to your repayment on the last day of the fixed term, regardless of what the RBA does.
What you give up is flexibility.
The Advantages of Fixing Your Rate
Repayment certainty Your monthly repayment is exactly the same for the entire fixed term. This makes budgeting straightforward and eliminates the anxiety of watching RBA announcements. For households with tight cash flow, a mortgage on a single income, or significant other financial commitments, this certainty has genuine psychological and practical value.
Protection against rate rises If the RBA continues hiking through 2026 — which CBA economists are forecasting — a borrower who fixes today locks themselves out of those increases for the duration of their fixed term. If variable rates move from 6.3% to 7.0% over 18 months and you’re fixed at 5.9%, that’s a meaningful saving on a $700,000+ loan.
Predictable planning horizon For first home buyers adjusting to the demands of mortgage repayments, knowing your obligations precisely for 2–3 years allows you to plan everything else — childcare, renovation budgets, investment contributions — without a moving financial variable at the centre.
The Disadvantages of Fixing Your Rate
Break costs — the one that stings If you exit a fixed loan before the term ends — because you sell, refinance, or wish to restructure — you may face a break cost (also called break fee or economic cost). This is calculated based on the difference between your locked rate and the lender’s current rate for the equivalent remaining term. In a rising rate environment, break costs are typically low or zero. But if rates drop significantly after you’ve fixed, break costs can be substantial — sometimes tens of thousands of dollars. This is the single biggest risk of fixing.
Limited or no offset account Most fixed rate loans do not offer an offset account. Those that do typically offer a partial offset. This is more significant than it sounds — see our dedicated section on offset accounts below.
Capped extra repayments Fixed loans typically cap additional repayments at $10,000–$30,000 per year. If your income improves and you want to aggressively pay down your loan, a fixed rate restricts that.
You miss out if rates fall Rate movements are never certain. If global conditions shift — inflation cools faster than expected, a recession materialises, geopolitical tensions ease — rates could fall. A borrower locked into a fixed rate above the market would be paying more than they need to, with break costs making it painful to exit.
What Is a Variable Rate Home Loan?
A variable rate home loan has an interest rate that moves over time — typically in line with the RBA cash rate, though lenders retain the right to adjust independently of RBA decisions for their own funding reasons.
When rates go down, your repayments go down. When rates go up, your repayments go up. It’s that direct.
The vast majority of Australian home loans are variable. According to the RBA, 98% of new owner-occupier loans originated in Australia are variable rate. That’s not just inertia — there are genuine structural reasons why variable is often the better long-term choice for most borrowers.
The Advantages of a Variable Rate
Unlimited extra repayments Most variable loans allow you to make extra repayments at any time, in any amount, without penalty. If you receive a bonus, inherit money, or simply get ahead on your salary, you can pour it directly into your mortgage. Given that reducing your principal early is one of the most powerful ways to reduce total interest paid over 25–30 years, this flexibility has enormous financial value.
Full offset account access This is the killer feature of variable loans. An offset account is a transaction account linked to your mortgage where every dollar sitting in the account reduces the loan balance on which you pay interest — dollar for dollar. We’ll go deeper on this shortly, because it’s genuinely one of the most powerful financial tools available to Australian mortgage holders.
No break costs If you sell your property, refinance to a better deal, or simply want to restructure your loan, you can exit a variable loan without financial penalty. In a market where refinancing to a competitive product can save $5,000–$10,000+ per year, this flexibility has real dollar value.
Benefit from rate cuts If the rate cycle peaks and the RBA eventually cuts, variable borrowers benefit immediately. Fixed borrowers wait until their term ends — potentially years later.
Access to a wider lender market Variable products outnumber fixed products significantly across Australia’s 40+ major lenders. This means more competition, more features, and more options to find a product that truly fits your situation.
The Disadvantages of Variable Rate
Repayment uncertainty The most obvious downside. If the RBA hikes three more times this year, your repayments go up each time. For households with little financial buffer, this creates genuine stress and potential mortgage difficulty.
Requires active management Variable borrowers who aren’t monitoring the market can end up sitting on their original lender’s standard variable rate — which is almost always significantly higher than the best available rate. Rate complacency is one of the most expensive financial mistakes Australian homeowners make. (This is exactly where a mortgage broker relationship pays for itself.)
Psychological pressure For many borrowers, particularly first home buyers, the uncertainty of not knowing what their repayments will be in 12 months is genuinely distressing. The value of certainty isn’t irrational — it’s a real human need that fixed rates address.
The Split Loan: Both, Strategically
A split loan divides your mortgage into two portions — one fixed, one variable — and is increasingly the solution recommended by mortgage brokers in the current environment.
You might, for example, fix 60% of your loan for 2 years (locking in certainty on the majority of your debt) while keeping 40% variable (preserving your offset account, extra repayment flexibility, and some benefit from any future rate cuts).
The ratio is flexible and entirely personal:
- A borrower with tight cash flow might fix 70–80% for maximum repayment certainty
- A borrower with strong savings and income might keep 70% variable to maximise the offset benefit
- An investor might keep 100% variable for tax and flexibility reasons (more on this below)
The trade-off: You’re managing two loan components, and some lenders charge fees for split products. There’s also no “perfect” split — it’s an educated hedge, not an exact science.
That said, in a market where rates have moved significantly and may continue to do so, the split structure is one of the most commonly recommended approaches by mortgage brokers right now. It acknowledges that nobody knows exactly what rates will do — and builds a loan structure that performs reasonably well under multiple scenarios.
Real Numbers: What the Fixed vs Variable Decision Actually Costs
Let’s put real dollar figures to this. Assume a $750,000 loan over 30 years:
| Scenario | Rate | Monthly Repayment | Annual Repayment |
|---|---|---|---|
| Competitive variable | 5.80% | $4,403 | $52,836 |
| Average market variable | 6.45% | $4,718 | $56,616 |
| Fixed 2-year (indicative) | 6.20% | $4,584 | $55,008 |
| Big 4 standard variable | 8.10% | $5,556 | $66,672 |
Rates are illustrative based on current market range. Actual rates depend on LVR, loan purpose, lender, and borrower profile.
The critical takeaway from this table: The difference between a competitive variable rate and a big four bank’s standard variable rate is over $13,800 per year on a $750,000 loan. This dwarfs the fixed vs variable debate entirely.
Before you agonise over fixing or staying variable, the most important question is: are you on a genuinely competitive rate? Many borrowers who’ve been with the same lender for 3+ years are sitting well above the market rate, silently paying thousands extra every year.
The Offset Account: Why It Changes the Variable Calculus
An offset account is one of the most misunderstood features in Australian home lending — and possibly the most powerful.
Here’s how it works: if you have a $600,000 variable mortgage and $50,000 sitting in your offset account, you only pay interest on $550,000. That $50,000 offsets your loan balance dollar for dollar, reducing your interest every single day. The $50,000 isn’t locked up — you can spend it, transfer it, and use it freely like any everyday account.
The real-world impact on a $600,000 mortgage at 6.0%:
| Offset Balance | Daily Interest | Annual Saving | Over 5 Years |
|---|---|---|---|
| $0 (no offset) | $98.63 | — | — |
| $20,000 offset | $95.34 | $1,200 | $6,000 |
| $50,000 offset | $90.41 | $3,000 | $15,000 |
| $100,000 offset | $82.19 | $6,000 | $30,000 |
This is why borrowers with savings, emergency funds, or investment capital routinely benefit more from a variable loan with an offset account than a fixed loan with a lower headline rate.
For investors, the offset account has an additional tax dimension — and this is where Centria’s dual expertise becomes directly relevant.
For an investment property, mortgage interest is generally tax-deductible. But here’s the nuance: a redraw facility and an offset account are not the same thing from a tax perspective. If you use redraw on an investment loan for personal purposes, you can contaminate the tax deductibility of that portion of the loan. An offset account, correctly structured, avoids this problem entirely. One wrong move in this area can cost you thousands in deductible interest — permanently.
This is the kind of detail that only surfaces when your mortgage broker and your accountant are in the same conversation.
Fixed Rates and Property Investors: Why the Answer Is Almost Always Variable
If you’re purchasing an investment property, the calculus tilts heavily toward variable rate loans in most cases. Here’s why:
Interest deductibility and loan structure Investment loan interest is deductible against your rental income. Maximising deductible interest — which means keeping your investment loan as large as possible while parking any surplus cash in an offset account linked to your non-deductible home loan — is a core property investment tax strategy. Fixed rates, which typically don’t offer offset accounts, make this structure impossible or much less efficient.
Portfolio flexibility Property investors often want to refinance, access equity, or restructure loans as their portfolio grows. Fixed rate break costs are a direct barrier to this flexibility. Being locked into a fixed structure at the wrong time can cost you an investment opportunity that’s time-sensitive.
Negative gearing strategy Negative gearing works best when your loan interest (a deductible cost) is maximised. This typically involves keeping variable, interest-only investment loans while aggressively offsetting your owner-occupied mortgage. The tax interaction between your home loan and your investment loan is something your mortgage broker and accountant should be designing together — not separately.
This is precisely the kind of integrated advice Centria Finance delivers. We don’t just find you a rate — we structure your loans to align with your tax position, your equity strategy, and your long-term wealth goals.
Break Costs: The Fixed Rate Risk Most Borrowers Underestimate
Break costs deserve their own section because they catch borrowers off guard more often than any other feature of fixed rate loans.
When do break costs apply?
- You sell your property before the fixed term ends
- You refinance to a different lender
- You want to switch from fixed to variable mid-term
- You pay off the loan in full before the fixed term expires
How are they calculated? Break costs are based on the difference between your locked rate and the lender’s current wholesale funding rate for an equivalent term. In simple terms: if you fixed at 6.5% and rates have since fallen to 5.5%, the lender has lost a profitable position — and you pay the difference for the remaining term.
In a rising rate environment (which is where we are now), break costs are typically low or negligible, because rates moving up means the lender’s new rate is higher than what you fixed at — there’s no loss for them to recoup.
But the moment the rate cycle turns — and it always eventually does — break costs can become very significant. Borrowers who fixed at high rates during the 2022–2023 cycle and then tried to refinance when rates fell found themselves facing break costs of $20,000–$50,000 or more. That experience is still fresh in many Australians’ memories.
The lesson: Before you fix, ask yourself honestly: Is there any scenario where I might want to exit this loan early in the next 1–3 years?
- Potential job change or relocation?
- Planning to upgrade or downsize?
- Expecting a large income increase that would support a major lump sum repayment?
If any of these apply, the flexibility of a variable loan may outweigh the certainty of a fixed rate — regardless of what the rate comparison looks like on paper.
What to Do When Your Fixed Rate Expires
One of the most costly moments in a borrower’s financial life is the end of a fixed rate period — and most borrowers handle it poorly.
When your fixed term expires, your loan automatically rolls onto the lender’s standard variable rate. This is almost always the lender’s highest variable rate — often a full percentage point or more above their best available rate for new customers.
Staying put at the revert rate is one of the most common and expensive forms of mortgage complacency in Australia. A borrower who fixes for 2 years and then passively rolls to the standard variable rate can easily end up paying 1.5–2.0% more than a similarly situated borrower who actively refinanced.
What to do instead:
- Mark your expiry date in your calendar 6 months out — negotiating a better rate or refinancing takes time
- Request a rate review from your lender — many will discount for customers who ask
- Shop the market — the competitive landscape changes significantly in 2 years; the best option at your original settlement may not be the best option today
- Talk to your mortgage broker — ideally one who maintains an ongoing relationship with you, not just a transaction-based one
At Centria Finance, we don’t disappear after settlement. We’re in your corner when your fixed term expires, when you’re ready to refinance, and when your circumstances change. That’s what an ongoing broker relationship looks like.
The Decision Framework: Which Loan Type Is Right for You?
There’s no universal answer. Here’s a practical decision guide based on borrower type:
You Should Consider Fixing If:
- Your cash flow is tight and a further rate rise would create genuine financial stress
- You are on a single income and need absolute repayment certainty
- You plan to stay in the property for at least the full fixed term (certainty you won’t need to exit early)
- You don’t have significant savings to deploy through an offset account
- The fixed rate available to you is meaningfully lower than the average variable rate
- You are a first home buyer adjusting to mortgage repayments for the first time and value predictability while you settle in
You Should Consider Variable If:
- You have strong savings or income that you can park in an offset account
- You are an investor structuring your loans for tax efficiency
- You have reasonable financial buffer to absorb rate fluctuations
- You anticipate a property sale, refinance, or major life change in the next 2–3 years
- You want to make large extra repayments aggressively
- You believe rate increases are near their peak and cuts are likely in the medium term
- You want access to the broadest range of competitive loan products
You Should Consider a Split Loan If:
- You want partial certainty on your largest debt exposure without giving up all flexibility
- You have meaningful savings to deploy through an offset component
- You’re uncertain about the rate direction and want to hedge both ways
- You’re a property investor or upgrader who wants to fix their owner-occupied portion while keeping investment loans variable for tax efficiency
The Rate Negotiation Most Borrowers Don’t Know to Have
Here’s an insight that applies regardless of whether you go fixed or variable: the rate advertised is not necessarily the rate you’ll get.
Lenders have pricing discretion. For borrowers with strong profiles — good credit history, stable employment, significant equity or deposit — there is almost always a better rate available than the headline offer. The question is whether you know how to ask for it, and whether you have the right person in your corner to negotiate on your behalf.
A mortgage broker’s role isn’t just to find the right lender — it’s to advocate for you within that lender’s pricing structure. With access to 40+ lenders, we know which lenders are currently competitive for your profile, which are offering cashback or fee waivers, and which are specifically competing hard for first home buyer or investor business at any given moment.
In a market where the difference between the best available variable rate (5.08%) and the average market rate (6.45%) is worth over $18,500 per year on a $900,000 loan, getting your rate right is not a minor detail. It’s one of the most important financial decisions you’ll make.
The Centria Finance Perspective: Mortgage and Tax, Designed Together
Most borrowers approach this decision by asking their bank or broker: “What’s your best fixed rate?” That’s a reasonable starting point. But it misses the bigger picture.
Your loan structure has tax consequences. The choice between fixed and variable affects your ability to deploy an offset account. Whether your investment loan is interest-only or principal-and-interest affects your deductible interest position. The order in which you pay down your home loan vs. investment loan has direct implications for your overall tax bill.
At Centria Finance, your loan is never designed in isolation from your tax situation. Our team includes both mortgage brokers and accountants — which means when we sit down with you to structure a loan, we’re looking at:
- Your current tax position — your marginal rate, existing deductions, negative gearing position
- Your short and long-term income profile — where you expect to be in 3 years, not just today
- Your full liability picture — how this loan interacts with any other loans, assets, or structures you hold
- Your wealth building goals — whether this property is your forever home, a stepping stone, or the first in a portfolio
That integrated view is how we ensure that a loan that looks competitive on paper actually performs well for your real financial life.

Frequently Asked Questions
Can I switch from fixed to variable before my term ends? Yes, but you will likely face a break cost. The size of the break cost depends on the difference between your fixed rate and the lender’s current rate for the equivalent remaining term. In a rising rate environment, break costs are typically low. Ask your lender for a break cost quote before making any decisions.
What happens to my offset account if I fix? Most fixed rate loans don’t offer an offset account, or offer only a limited version. Your savings in an offset account would need to either be redeployed elsewhere or deposited as an extra repayment before fixing. This is one of the most important considerations when comparing fixed and variable options.
Is it worth paying LMI to get a lower rate? Generally no — LMI is a one-off cost while rate differences compound over decades. But every situation is different. We model this at no charge for our clients.
Can I have a fixed rate on my investment property? Yes, but it’s rarely recommended due to the tax efficiency advantages of a variable loan with an offset account for investment properties. There are specific circumstances where fixing an investment loan makes sense — we can help you assess whether yours is one of them.
What if the RBA starts cutting rates — am I better off variable? If the rate cycle turns and the RBA begins cutting, variable borrowers benefit immediately with each cut. Fixed borrowers are locked at their agreed rate until the term expires. Whether variable or fixed performs better depends entirely on the timing and magnitude of any future cuts — which nobody can predict with certainty.
