Key Takeaways
- Coming off a fixed rate usually means rolling onto your lender’s revert rate, which is often set well above the sharpest deals on the market.
- With the cash rate at 4.35% in mid-2026 after three rises this year, the size of any repayment jump depends on your old rate and today’s pricing, not the ultra-low rates of a few years ago.
- Acting three to six months before your fixed term ends gives you time to compare, negotiate and switch before the rollover happens by default.
- Fixed, variable and split each suit different goals, and break costs, LMI and loan term all shape whether switching actually pays off.
Coming off a fixed rate can reshape a monthly budget. Your repayments have held steady for two or three years, then the fixed term ends and the number changes. For many households whose fixed rate is expiring in 2026, the real concern is whether the new repayment stays manageable or lands as a shock.
A repayment jump is rarely inevitable. It usually results from doing nothing and letting the loan roll onto the lender’s revert rate. With a clear plan and a little lead time, the end of your fixed term becomes a decision point rather than an ambush. That is where working with a refinancing mortgage broker can protect your cash flow and keep your options open.
The 2026 backdrop matters. The Reserve Bank of Australia (RBA) lifted the cash rate three times early in the year, to 4.35%, so the market you are rolling into looks different from the one you left. Understanding what happens at rollover, and moving early, gives you time to plan the switch rather than absorb it.
What Coming Off a Fixed Rate Means in 2026
A fixed rate ending is a mechanical event, not a penalty. The mechanics show where the risk and the opportunity sit:
The Revert Rate Trap
When your fixed term finishes, your loan does not continue at the same rate. Unless you arrange something new, it rolls onto your lender’s revert rate, which is usually the standard variable rate. That rate is often set above the sharper deals the same lender offers new customers, so the default path tends to be the most costly one. The rollover happens automatically, which is why the decision can slip past a busy household without anyone choosing it.
The 2026 Interest Rate Backdrop
Rates have moved. The RBA increased the cash rate in February, March and May 2026 before holding at 4.35% in June, and lenders passed those rises through to variable rates. Fixed rates shifted too, though not always by the same margin. Variable rates advertised across the market commonly sit around 6% or higher, and the difference between the cheapest and most costly variable rates can be more than 2%. Where your revert rate falls in that range changes your repayment. The next cash rate decision, due in August 2026, is one to watch, since a further move would usually flow through to variable rates within a few weeks.
The Real Source of the Jump
The mortgage cliff headlines of a few years ago described borrowers rolling off pandemic-era fixed rates near 2% onto rates several times higher. A rollover in 2026 is usually gentler, because a fixed rate locked in during 2023 or 2024 was already closer to today’s pricing. The jump now tends to come from the gap between a competitive old rate and an uncompetitive revert rate, rather than from a historic low. That is a more manageable problem, and often a fixable one.
The Repayment Recalculation at Rollover
Rolling off a fixed rate also resets how your repayment is worked out. The lender sets a new minimum based on your remaining balance, the years left on the loan and the new rate, so the change you feel is driven by all three, not the rate on its own. A loan with more of its term already behind it can absorb a rate rise more comfortably than a newer one. Seeing this recalculation in advance, rather than on your first statement, lets you plan around it.
Your Step-by-Step Plan to Avoid a Repayment Jump
These steps turn the end of your fixed term into a planned switch rather than a default you stumble into:
Marking Your Expiry Date Early
Find the exact date your fixed term ends. It sits on your loan documents or in your online banking. Aim to start reviewing your options three to six months out, because a refinance can take several weeks once valuations, credit checks and lender assessment are factored in. Starting early also means a delay on the lender’s side will not tip you onto the revert rate by accident.
Reviewing Your Current Rate Against the Market
Once you know your revert rate, compare it with what is currently available. A gap of even half a percentage point on a large balance can be worth thousands over time. Look past the headline number and check the comparison rate, which folds in most fees, so you compare like with like.
On a $600,000 loan over 25 years, a difference of around one percentage point in your rate can change repayments by roughly $350 to $400 a month, which is more than $4,000 a year.
These figures are illustrative only. Your actual rate, repayment and savings will depend on your balance, loan term, lender and personal circumstances, so check the specific numbers for your own loan before deciding.
Gathering Your Documents Early
Lenders reassess your position when you refinance, so recent payslips, tax returns where you are self-employed, account statements and identification all keep things moving. Pulling this together before you apply reduces back-and-forth and lowers the chance of a delay that leaves you sitting on the revert rate. A tidy application also presents your income and expenses accurately.
Comparing Options Across Lenders
Your current lender is one option, not the only one. A retention offer to keep your business can be worthwhile, but weigh it against what other lenders offer new customers. Looking across a wide panel rather than a single bank widens the pricing and policy you can reach, which counts for most when your situation is not straightforward. It also helps to separate a genuinely lower rate from a short-lived discount that reverts after a year or two.
Locking In Before the Rollover Date
Confirm the new rate and product before your fixed term expires, then check the first repayment against your budget so there are no surprises. Where a switch completes just before the rollover, you move straight from one arranged rate to the next and skip the revert rate entirely. That timing turns a potential jump into a smooth transition.
Choosing Between Fixed, Variable and Split in 2026
There is no single right structure, only the one that fits your situation. Each option answers a different question about certainty, flexibility and where you think rates are heading:
When Fixing Again Makes Sense
Fixing suits households that value a predictable repayment and want protection if rates rise further. With some economists still expecting the RBA to move again in 2026, locking a rate can steady a tight budget. The trade-offs are real, though. Fixed loans usually cap extra repayments, often limit or remove offset access, and charge break costs if you exit early, so certainty comes at the price of flexibility.
When Variable Suits You Better
A variable rate keeps your options open. You can generally make unlimited extra repayments, use an offset account to reduce the interest you pay, and refinance later without break costs. Some competitive variable rates currently sit close to available fixed rates, so borrowers who expect the next move to be down, or who value flexibility, may lean variable. The catch is that your repayment can rise again if the cash rate does.
When a Split Loan Bridges Both
A split loan fixes one portion and keeps the rest variable, which hedges the decision rather than betting the whole loan on a single view. A common approach is to fix the larger share for repayment certainty while keeping a variable slice with an offset and free extra repayments. For a household that wants some protection without giving up all flexibility, a split can be a sensible middle path.
Costs and Traps to Check Before You Switch
Switching can save money, but only once you have accounted for the costs on both sides. Run through these before you commit so the savings are real rather than assumed:
- Break costs on your current fixed loan, which can be significant if you exit before the term ends and may outweigh the saving.
- Discharge and application fees, including any settlement or valuation charges the new lender applies.
- Lenders Mortgage Insurance (LMI) where your equity is below 20%, since a fresh premium can erode the benefit of a lower rate.
- Loan term creep, where a new 30-year loan quietly stretches the years left on your mortgage and adds interest over time.
- Cashback offers, which can be genuinely useful but should be weighed against the ongoing rate rather than taken at face value.
- Comparison rates rather than headline rates, so fees are counted and not just the advertised number.
This is a general guide, not a complete list. Which costs apply, and how they weigh up, will depend on your lender, loan size and circumstances, so confirm the figures for your own situation before deciding.
Even when a full switch does not stack up, smaller wins are often available, from negotiating your current lender down to keeping your repayment at its old level so you pay off your mortgage faster. A knock-back still leaves room for Plan B refinancing strategies that trim your costs.
When Your Situation Is More Complex
Straightforward loans roll over cleanly. Where your income or ownership structure is less standard, timing and lender choice matter more, and starting early counts most:
Self-Employed and Variable Income
Self-employed borrowers and contractors are assessed on documents such as tax returns and business financials, which take longer to prepare and vary more between lenders. A rate that looks fine at a bank you already use may not be the one that reads your income most favourably. Working with a broker who knows which lenders assess your figures fairly can be the difference between a clean approval and a knock-back at the wrong time.
Trust and Self-Managed Super Fund (SMSF) Borrowers
Loans held in a family trust or an SMSF sit with a smaller pool of lenders and carry stricter policy. A rollover here is not a quick comparison exercise, because entity requirements, guarantor obligations and SMSF lending rules all shape what is possible. Extra lead time lets these applications be structured properly rather than rushed against a deadline.
Multiple Properties and Portfolio Timing
Investors often face more than one fixed rate expiring across a portfolio. Refinancing one security can affect the others, especially where loans are cross-collateralised, so the order and timing of each move matters. A coordinated plan across the portfolio usually protects both cash flow and future borrowing capacity better than treating each loan in isolation. Spacing the rollovers, where the terms allow it, can also stop valuations and applications from colliding in the same short window.
Approaching Your Rollover With Confidence
The end of a fixed term stops being stressful the moment it becomes a decision you control. With your expiry date marked, your revert rate checked and your options mapped, you are no longer waiting to see what turns up in your account. You are choosing the rate and structure that suit your circumstances, on your timing rather than the lender’s.
That shift, from reacting to planning, is where good guidance earns its place. The team at Unconditional Finance can compare your position across a wide lender panel, structure the switch around your goals, and keep reviewing your rate long after settlement, so coming off your fixed rate becomes a step forward rather than a setback.
Frequently Asked Questions (FAQs)
1. How early should I act before my fixed rate ends?
Aim to start three to six months before the expiry date, since the process can take several weeks. Even where you decide to stay put, an early review costs nothing and confirms you are on a fair rate.
2. What is a revert rate and why does it matter?
A revert rate is the rate your loan moves to automatically when the fixed term ends, usually the lender’s standard variable rate. It tends to be higher than the deals available to new customers, so leaving your loan on it is often the most costly option. Knowing your revert rate is the first step in judging whether to negotiate, switch or refix.
3. Should I fix again or move to a variable rate in 2026?
That depends on your cash flow, your plans and your view on where rates go next. Fixing gives repayment certainty and protection if rates rise, while variable offers flexibility, offset access and no break costs. Some borrowers use a split loan to capture a measure of both. There is no universal answer, so model your repayments under each option before deciding.
4. Will I definitely face a big repayment jump in 2026?
Not necessarily. A fixed rate set in 2023 or 2024 was already close to current pricing, so the rise now is usually smaller than the earlier mortgage cliff and often comes from an uncompetitive revert rate. Acting before the rollover can reduce or remove it.
5. What costs should I weigh before refinancing?
Check break costs on your current loan, discharge and application fees, any new LMI where your equity is under 20%, and whether a new loan term stretches your remaining years. A switch is worthwhile only when the savings clearly outweigh these costs.
6. How is a rollover different from breaking my loan early?
Rolling off happens naturally at the end of your agreed term and carries no break cost. Breaking a fixed loan means exiting before that term ends, which can trigger a break cost based on the interest the lender expected to receive. Timing a switch to land at or just after your expiry date is how most borrowers sidestep that charge.
7. Can I still refinance if my property value has fallen?
Possibly, though it depends on your remaining equity. Where the value has dropped, your loan-to-value ratio may be higher, which can narrow your options or bring LMI into play on a new loan. A review will show whether a switch still stacks up or whether negotiating with your current lender is the stronger move for now.
8. Can a broker help if my income or structure is complex?
Yes. Self-employed income, trust and SMSF loans, and multi-property portfolios each sit with a narrower set of lenders and stricter policy. A broker who compares across the market can match you with a lender that reads your situation fairly, which matters most when a deadline is approaching.
