Key Highlights
- Variable rates move with the RBA cash rate and offer flexibility features like offset accounts and unlimited extra repayments, whilst fixed rates lock your rate for a set term and offer repayment certainty but limited flexibility
- The RBA has raised the cash rate twice in 2026 to 4.10% and all four major banks are forecasting a further rise in May, which changes how you should think about fixing right now
- Breaking a fixed rate loan early can cost tens of thousands of dollars which means that you need to understand the break cost risk before you fix, especially in a rising rate environment
- A split loan fixes part and keeps part variable meaning it captures certainty on a portion of the debt while preserving offset and flexibility on the rest
- The right choice depends on your specific situation such as income stability, plans to sell or refinance, need for an offset account, and your personal tolerance for payment uncertainty all matter more than trying to predict what the RBA will do next
The Honest Answer: It Depends
Fixed versus variable is the question we get asked more often than almost any other at Stanford Financial. Clients want a clear answer: which one is better? The honest answer, the one a broker gives rather than a bank, is that it depends entirely on your situation.
Banks produce comparison guides on this topic too, but they have an inherent conflict of interest. They make more money on fixed rate loans in certain rate environments and have an incentive to steer borrowers toward the product that suits the lender rather than the borrower. As an independent broker with access to over 50 lenders, Stanford Financial has no such incentive. Our job is to recommend what is right for you and not what is easiest for us to write or most profitable at this point in the rate cycle.
This guide covers how each loan type works, what the current rate environment means for the fixed versus variable decision in 2026, the split loan option most borrowers overlook, and the questions to ask before deciding. It does not tell you which to choose without knowing your situation, because that would be irresponsible. But it gives you the framework to make an informed decision and to have a more productive conversation with your broker.
How Variable Rate Home Loans Work
A variable rate home loan has an interest rate that moves over time. It is set by your lender with reference to, but not always in direct lockstep with, the Reserve Bank of Australia’s official cash rate. When the RBA raises the cash rate, variable rate borrowers typically see their lender pass through most or all of the increase within weeks. When the RBA cuts, variable rate borrowers benefit, again typically within weeks.
The rate movement mechanics
The RBA sets the cash rate at its scheduled meetings, which now occur eight times per year. The cash rate is the rate charged on overnight loans between financial institutions, and it serves as the benchmark from which lenders price their home loan products. Most lenders pass through RBA rate changes in full, though they are not legally required to do so and the timing can vary.
As at April 2026, the RBA cash rate is 4.10%, following rate increases of 25 basis points each in February and March 2026. Variable rate home loans are currently priced in a range of approximately 5.60% to 5.90% for standard owner-occupied principal and interest loans, depending on the lender, the LVR, and the loan amount.
What variable rate loans offer
- Offset accounts: a 100% offset account linked to your variable rate home loan reduces the daily interest calculation on your loan by the amount sitting in the offset. Every dollar in offset earns the equivalent of your loan rate in tax-free savings. On a $700,000 loan at 5.8%, maintaining a $50,000 average offset balance reduces your annual interest bill by $2,900. This feature is available on most variable rate products but is generally not available on fixed rate loans
- Unlimited extra repayments: variable rate loans typically allow you to make additional repayments of any amount at any time without penalty. Each extra repayment reduces the principal balance and therefore the interest charged over the remaining loan term
- Redraw facility: most variable rate loans with extra repayments include a redraw facility, allowing you to access the additional amounts you have paid in case you need them for renovation, investment, or unexpected expenses
- No break costs: variable rate loans have no penalty for early exit, early repayment, or refinancing. You can switch lenders, sell the property, or pay the loan off entirely at any point without a financial penalty
The offset account is the single most powerful feature of a variable rate loan. For borrowers who can maintain a meaningful balance in offset, the interest saving over a 30 year loan term can be tens of thousands of dollars. This is a key reason why variable rate loans remain attractive even in a rising rate environment.
How Fixed Rate Home Loans Work
A fixed rate home loan locks your interest rate for a set period, typically one, two, three, or five years. For the duration of the fixed term, your rate does not change regardless of what the RBA does. Your repayments are constant and predictable. At the end of the fixed term, the loan rolls to a variable rate — usually the lender’s standard variable rate unless you refinance or fix again.
What fixed rate loans offer
- Repayment certainty: your monthly repayment amount is fixed for the entire term. If the RBA raises rates three more times over the next 18 months, your repayment does not change. This certainty is valuable for borrowers on tight budgets, single income households, or those who are at the upper limit of their servicing capacity
- Protection from rising rates: in a rising rate environment, a fixed rate provides a defined cost ceiling. You know exactly what the loan will cost for the fixed period regardless of what happens to monetary policy
- Budgeting simplicity: predictable repayments make household budgeting easier and remove the psychological stress of watching rate announcements and calculating what each move means for your finances
What fixed rate loans do not offer
- Offset accounts: the vast majority of fixed rate products do not offer 100% offset accounts. Some lenders offer partial offset arrangements or allow a linked savings account to reduce interest but under different terms. The loss of the offset account is the most significant financial cost of fixing for borrowers who maintain a meaningful savings buffer
- Unlimited extra repayments: most fixed rate loans cap extra repayments at $10,000 to $20,000 per year during the fixed term. Repayments above this cap may trigger break costs. This limits the ability to aggressively pay down the principal during a period of income growth
- Flexibility to exit: if you need to sell the property, refinance, or pay out the loan during the fixed term, you will face a break cost calculated on the difference between your fixed rate and current market rates for the remaining term. In some market conditions, this cost can be substantial
Understanding Fixed Rate Break Costs
Break costs are the most misunderstood aspect of fixed rate home loans and the source of the most expensive surprises for borrowers who did not fully understand what they were signing up for.
A break cost is charged when you exit a fixed rate loan before the end of the fixed term. It compensates the lender for the loss they incur by having to reinvest the funds at current market rates, which may be lower than your fixed rate.
How break costs are calculated
Break costs are typically calculated based on the wholesale interest rate differential between your fixed rate and the current market rate for the remaining term of your loan. The formula is broadly: break cost = loan balance × rate differential × remaining term in years.
In an environment where rates have risen since you fixed, which is the current situation in Australia, your fixed rate is lower than current market rates, meaning the rate differential works in your favour and the break cost may be zero or very small. However, if you fixed at a higher rate than current market rates, or if rates fall substantially from here, the break cost can be very large.
Current break cost implications
In the current environment, where the RBA has raised rates twice in 2026 and all major banks are forecasting further increases, borrowers who fixed their loans in 2024 or early 2025 at lower rates may face significant break costs if they try to exit their fixed loan. If your current fixed rate is below the new rates available in the market, the bank will charge you the difference to exit. Check your loan terms carefully before assuming you can refinance away from a fixed rate without cost.
Before fixing, always ask your broker or lender to explain exactly how break costs would be calculated on the specific product you are considering, and ask them to model the break cost in a scenario where rates fall by 1% to 2% during your fixed term. This scenario feels unlikely when rates are rising but rate cycles turn, and the cost of being wrong about timing can be significant.
Split Loans: The Hybrid Option
A split loan divides your home loan into two portions with one fixed and one variable. You choose the split, commonly 50/50 or 70/30, and each portion operates under its respective product terms. The variable portion retains the offset account and flexibility features. The fixed portion provides rate certainty on that portion of the debt.
Split loans are often the most sensible choice for borrowers who are uncertain about the rate outlook or who want to hedge against being entirely wrong in either direction. They are also useful for investment loan structuring, where keeping the investment portion variable maximises offset account usage and tax efficiency, while the owner-occupied portion can be partially fixed for budget certainty.
How to decide the split ratio
The fixed portion should broadly represent the amount you want certainty on, typically the minimum monthly payment that fits comfortably in your budget. The variable portion represents the debt you want to pay down aggressively or maintain an offset against.
Example: a $700,000 loan split 60/40 with $420,000 fixed at a two year rate and $280,000 variable with offset. The fixed portion provides certainty on the majority of the debt. The variable portion allows the borrower to maintain their savings in offset and make extra repayments above the fixed cap. If rates rise, the fixed portion is protected. If rates fall, the variable portion benefits.
Split loans are arranged through the same lender across both portions. Not every lender offers split structures on competitive terms, the best deal overall may involve a lender whose split product is less flexible than a pure variable or pure fixed from another lender. A broker compares the split option against the best pure variable and best pure fixed available on the market before recommending the structure.

| Best rate environment | When rates are falling | When rates are rising |
| Flexibility | High | Low during fixed term |
The Current Rate Environment: What It Means for Your Decision
Understanding the current rate environment is important context for the fixed versus variable decision and not because you should try to time the market, but because it helps you understand the trade-offs you are making at this specific point in time.
Where rates are right now
The RBA has raised the cash rate twice in 2026 to 3.85% in February and to 4.10% in March driven by renewed inflationary pressures in the second half of 2025 and global energy price impacts from the Middle East conflict. The March decision was made by a five to four split in the monetary policy board, indicating meaningful division among board members about whether further tightening was warranted.
Variable rate home loans are currently priced in approximately the 5.60% to 5.90% range for standard owner-occupied principal and interest loans. All four major banks are currently forecasting a further 25 basis point rise in May 2026, which would take the cash rate to 4.35%. Whether that eventuates depends on upcoming inflation data, labour market conditions, and how the global energy situation evolves.
What the rate cycle means for fixing
In a rising rate environment, the instinct to fix is intuitive because you want to lock in a rate before it rises further. But the fixed rates available from lenders already reflect market expectations about where rates will go. Lenders price their fixed products based on bank bill swap rates and bond market pricing, which build in anticipated future rate movements. When the market expects rates to rise, fixed rates tend to be priced above current variable rates to reflect that expectation.
This means that if all four major banks’ forecasts are correct and rates rise to 4.35% in May, fixing today does not necessarily save you money because the fixed rate you are offered today already prices in that expected increase. You are paying to lock in certainty, not necessarily to pay less interest in total.
The genuine financial benefit of fixing comes when rates rise more than the market expected at the time you fixed. If you fix at 6.0% and rates rise to 7.0%, you have saved real money. If you fix at 6.0% and rates stop at 6.2% before falling, you may end up having paid more than a variable borrower over the same period.
This is the fundamental challenge with rate timing: you are betting against a market of professional bond traders and bank economists who are priced into the fixed rate you are being offered. Most financial research suggests borrowers are better served by choosing the rate type that suits their flexibility needs and risk tolerance rather than trying to outsmart the market’s rate expectations.
The broker’s perspective on the current market
At Stanford Financial, our position in the current environment is that the decision to fix or stay variable should be driven primarily by your personal financial circumstances rather than a bet on the rate outlook. If you genuinely cannot absorb another two or three rate rises without significant financial stress, fixing provides real value as insurance against that outcome. If you have a solid income buffer, an offset account, and medium to long term plans with the property, staying variable preserves the flexibility and offset benefits that compound significantly over time.
For clients on investment loans specifically, the current environment warrants careful modelling. Investment loans are typically interest only with no offset benefit from principal reduction. The interest cost is fully deductible, which means the after-tax rate differential between fixed and variable is less dramatic than it appears at face value. The flexibility to refinance without break costs as the market evolves is worth more on an investment loan than on an owner-occupied loan in most situations.
Who Suits Variable and Who Suits Fixed
| Variable rate suits you if… | Fixed rate suits you if… |
| You want an offset account to reduce interest | You need budget certainty and a predictable repayment |
| You plan to make extra repayments | You are at or near your maximum borrowing capacity |
| You may sell or refinance within 2 to 3 years | You are on a tight income and cannot absorb rate rises |
| You are comfortable with repayment fluctuations | You want to set and forget your home loan for a period |
| Rates are expected to fall or are near peak | You believe rates will rise further before they fall |
| You want maximum flexibility for your portfolio | You are buying an investment and want known cashflow |

Questions to Ask Before You Decide
Rather than starting with “what do you think rates will do”, start with these questions about your own situation:
How long will you hold this loan before selling or refinancing?
If you are likely to sell or refinance within two to three years, fixing is risky because of break costs. The shorter your expected loan term, the more valuable variable rate flexibility becomes. If you are buying a forever home and plan to hold for 20 plus years, the flexibility argument for variable becomes less compelling relative to the certainty benefit of fixing for a period.
Do you have a meaningful savings buffer to offset?
If you maintain savings that could be placed in offset, the financial case for variable is very strong. An offset account is one of the highest-returning financial instruments available to an Australian property owner as your savings earn your loan rate, tax-free, without risk. Giving that up by fixing needs to be weighed against whatever rate certainty the fixed product provides.
How stable is your income?
A single income household, a borrower who is self-employed with variable revenue, or someone on a probationary employment contract may genuinely benefit from the repayment certainty of a fixed rate. An unpredicted rate rise at a difficult income moment is more damaging than the long-run cost of locking in a slightly higher rate.
Are you planning renovations or significant extra repayments?
Renovation costs often end up higher than budgeted. If you are planning a major renovation, having a redraw facility and the ability to manage cash flow flexibly on a variable rate is significantly more practical than working within fixed rate extra repayment caps. Similarly, if you are expecting a significant income increase or an inheritance and plan to make a large lump sum repayment, a variable rate loan avoids the break cost that would apply on a fixed product.
How will you react emotionally to repayment increases?
This is a question brokers rarely ask but should. If a rate rise would cause you ongoing anxiety and stress regardless of whether it is financially manageable, the psychological value of a fixed rate has real worth. Managing money is partly behavioural, and a structure that allows you to sleep well is not irrational. The costs of financial stress on health and relationships are real even when the rate choice is marginally suboptimal from a pure numbers perspective.
Why a Broker Makes the Fixed vs Variable Decision Better
The fixed versus variable question is superficially simple but is made in the context of a large number of lender-specific variables that most borrowers do not have visibility into:
- Fixed rates are not uniform: the fixed rate for a two year term at one lender may be 0.3% to 0.5% different from another lender for an otherwise identical loan. Some lenders discount fixed rates aggressively to attract business at specific points in the rate cycle. A broker with access to 50 plus lenders sees these differences daily
- Break cost formulas vary: different lenders calculate break costs differently. Some use a more transparent formula than others. A broker can explain the specific break cost risk on each product before you commit to a fixed term, not just the headline rate
- Offset on fixed varies: while most lenders do not offer a true 100% offset on fixed rate loans, some offer partial offset or linked savings arrangements that partially replicate the benefit. These are not widely advertised and a broker knows which lenders offer them
- Split loan combinations differ: some lenders offer split loans only within their own product suite. Others have competitive variable products but weaker fixed products, making a split with two different lenders on different portions an option in some cases
- Rate lock options: when you apply for a fixed rate loan, the rate is typically locked for a short period while your application is assessed. If rates rise before settlement, you could end up with a higher fixed rate than you applied for. Some lenders offer a paid rate lock that guarantees the rate at application until settlement — a broker can advise which lenders offer this and whether it is worth the cost in the current environment

Frequently Asked Questions
Should I fix my home loan in 2026?
Whether to fix depends on your personal circumstances rather than a view on where rates will go. In the current environment, all four major banks are forecasting further rate rises in 2026, which makes fixing for budget certainty a rational choice for borrowers who cannot absorb further increases. However, fixed rates already reflect market expectations of those rises, so fixing is not guaranteed to produce a lower total interest cost than staying variable. A broker can model the total cost of both options at your specific loan amount and fixed rate quote before you commit.
What is the difference between a fixed and variable home loan?
A fixed rate home loan locks your interest rate for a set period, typically one to five years, giving you predictable repayments but limited flexibility. A variable rate home loan has a rate that moves with market conditions, typically in line with RBA cash rate changes, and offers features like offset accounts, unlimited extra repayments, and no break costs for early exit. A split loan divides the loan between fixed and variable portions.
What happens when my fixed rate expires?
At the end of the fixed term, your loan automatically rolls onto the lender’s standard variable rate — which is typically not the most competitive variable rate available. This is a critical moment to either negotiate a better rate with your existing lender or refinance to a more competitive product. Many borrowers on expiring fixed terms are sitting on significantly uncompetitive rates without realising it. Set a reminder three months before your fixed term expiry to review your options.
What is a home loan break cost and how is it calculated?
A break cost is charged when you exit a fixed rate loan before the end of the fixed term. It is calculated based on the difference between your fixed rate and current wholesale market rates for the remaining term, multiplied by the outstanding loan balance and the remaining time. In a rising rate environment where your fixed rate is below current market rates, break costs may be zero or minimal. In a falling rate environment, break costs can be very significant and sometimes exceeding $30,000 or more on large loans with long remaining terms.
Can I have both fixed and variable on the same loan?
Yes. A split loan allows you to fix a portion of your home loan while keeping the remainder variable. This is arranged with a single lender and allows you to have offset account benefits and flexibility on the variable portion while locking in certainty on the fixed portion. The split ratio is your choice and a broker can model different ratios to find the right balance for your situation.
Is a variable rate home loan better than fixed?
Neither is universally better and the right choice depends on your circumstances, financial risk tolerance, plans for the property, and whether the offset account and flexibility features are important to you. Variable suits borrowers who need flexibility, have offset savings, and can absorb rate movements. Fixed suits borrowers who need budget certainty and are prepared to trade flexibility for predictability. A split loan captures elements of both. A broker can model both options at your specific loan amount before you decide.
