When Should You Refinance Your Home Loan? The Triggers, the Cadence and the Break-Even Rule (2026)
Most borrowers ask when to refinance as if the calendar holds the answer. It does not. The loan tells you: a fixed term ending, a gap that has widened, a valuation that has grown. This guide covers the triggers, the review cadence and the break-even rule that decides.
Review your home loan once a year, but refinance on triggers, not the calendar: a fixed term ending, a rate gap that has widened, a valuation that has grown, or changed plans. The break-even rule decides: divide total switching costs by the monthly saving; under a year is a green light.
Ask five borrowers when to refinance and you will hear five calendar answers: every two years, every rate cut, every new financial year. The calendar is the wrong instrument. Loans do not go stale on a schedule; they go stale when something changes, and the change is what you should be watching for. This guide covers the five triggers that justify a move, the review cadence that catches them early, how often you can realistically switch, the situations where staying put wins, and the one piece of arithmetic that settles every case. If you want the mechanics of the process itself, start with our guide to refinancing in plain English. This is general information, not credit assistance, and lender criteria apply.
- Review yearly, act on triggers. A once a year review is the habit; the refinance itself waits for a real trigger, such as a fixed term ending or a rate gap that has quietly widened.
- The gap is real. Moneysmart notes there can be a difference of more than 2% between variable home loan rates on the market, which is why an unchecked loan tends to drift expensive.
- There is no legal limit on how often you can refinance. The 6 to 12 month gap you hear about is a market convention, shaped by lender preferences and credit file hygiene, not by any law.
- The break-even rule decides. Divide total switching costs by the monthly saving to get the months until the move pays for itself. Under 12 months is usually a strong case.
- Sometimes the answer is stay. Selling soon, a small remaining balance, a deep fixed term or equity under 20% can each turn a tempting switch into an expensive one.
- The broker line is zero. Everstone charges you nothing: the lender pays us when the loan settles, so finding out where you stand costs nothing to start.
What Are the Signs It Is Time to Refinance?
Five triggers justify refinancing: your fixed term ends within about three months, your rate has drifted away from what new customers are offered, your property valuation has grown enough to change your equity position, your circumstances have changed, or your loan is missing features you now need.
None of these show up on a calendar. They show up on your loan statement, in your suburb, and in your life. The discipline is not refinancing often; it is noticing quickly.
| Trigger | What it looks like | Your first move |
|---|---|---|
| Fixed term expiring | The expiry date is inside the next three months | Start comparing now, before the loan rolls to a revert rate by default. Our fixed rate expiry guide covers the four real options |
| Repayment creep | Your rate has drifted from what your own lender offers new customers | Ask your lender to reprice first. Our negotiation playbook scripts the call |
| Valuation growth | Similar homes nearby now sell for clearly more than when you settled | A stronger equity position can mean sharper pricing, and above 20% equity it generally removes lenders mortgage insurance from the equation |
| Changed circumstances | New income, new family member, an investment plan, a renovation | Restructure around the life you have now, not the one you had at settlement |
| Missing features | No offset account, no split option, clumsy redraw | Price what the gap costs you each month; features are part of the rate conversation |
The second trigger deserves the most attention, because it is the quiet one. Nothing announces it. Your loan simply ages while new customers are offered sharper pricing, and the gap compounds every month you do not look. Across Everstone’s own refinance files, the most common starting point is the simplest one: a loan nobody has reviewed in years. Moneysmart notes there can be a difference of more than 2% between variable home loan rates on the market, and its first piece of switching advice is to ask your current lender for a better deal before you move. Whether that repricing request or a full switch is the right play is a decision of its own; we break it down in same bank or switch: repricing versus refinancing.
How Often Should You Review Your Home Loan?
Once a year as a habit, plus three natural checkpoints: the end of the financial year, each RBA cash rate decision, and the three months before any fixed term expires. A review is not a refinance; most reviews end with a repricing request or a clean bill of health.
The yearly review is a convention, not a law of nature, but it earns its place. The Reserve Bank of Australia announces a cash rate decision at 2.30 pm after each Monetary Policy Board meeting, with any change taking effect the following day, and eight of those decisions arrive every year. Each one flows through to home loan pricing at different speeds for different lenders, which is exactly how gaps open between what you pay and what new customers are offered. You do not need to react to every decision. You need a standing habit that catches the drift before it compounds.
A review does not mean paperwork. It means twenty minutes with your statement: what rate you are paying, what your balance is, what your property is plausibly worth now, and what your own lender is advertising to people who are not yet customers. Our five step home loan self-audit walks through exactly what to check and in what order. If the audit says the loan is expensive, this page tells you what to do about the timing.
How Often Can You Refinance Your Home Loan?
As often as a lender will approve you: no Australian law sets a minimum time between refinances. In practice a 6 to 12 month gap between moves is the market convention, because every application adds an enquiry to your credit file and frequent switching can make lenders cautious.
The legal answer and the practical answer are different, and it pays to know both. Legally, nothing stops you refinancing twice in a year. Practically, three things impose a rhythm. First, every application is recorded as an enquiry on your credit report, and a cluster of enquiries in a short window reads poorly to the next lender who assesses you. Second, some lender policies quietly favour borrowers with a little tenure on their current loan. Third, switching has fixed costs, and the break-even arithmetic below rarely rewards moves spaced closer than the savings can recover.
Treat the 6 to 12 month figure as what it is: a convention of the market, not a rule and not a promise about any particular application. If your fixed term ends four months after you last refinanced and the numbers clearly favour a move, the convention should not stop you running the maths.
When Is Refinancing Not Worth It?
Skip the refinance when you plan to sell soon, when the remaining balance is too small for the saving to clear the switching costs, when you are deep inside a fixed term and the break cost swamps the gain, or when equity under 20% means lenders mortgage insurance would eat the benefit.
You are selling soon. The break-even rule needs time to work. If the property is likely to be sold before the switch pays for itself, the costs are real and the savings are theoretical. Put the effort into the sale instead.
The balance is small. The same rate improvement that saves thousands a year on a large balance may save only a few hundred dollars on a small one, and the fixed costs of switching do not shrink to match. On small balances, a repricing request to your current lender often beats a full refinance.
You are deep inside a fixed term. Leaving a fixed rate early can trigger a break cost, and only your lender can quote the real number, because it moves with the market. Before any decision, get the written break quote and add it to the switching costs. Our guide to home loan break costs and exit fees explains how the number is calculated and how to request yours.
Your equity is under 20%. Moneysmart warns that switching with less than 20% equity can mean paying lenders mortgage insurance, and that cost can outweigh the saving from a sharper rate. If a rising valuation will carry you past the 20% line within a year, waiting can be the profitable move.
The only reason is a cashback. A cashback is a sweetener, not a trigger. It belongs inside the break-even arithmetic as a cost offset, nothing more. We run the honest cashback maths separately, including the ways a cashback loan can cost more than it pays.
The Break-Even Rule
Add up every cost of switching, then divide by the monthly saving the new loan delivers. The answer is the number of months before the move pays for itself. Under 12 months is usually a strong case. Longer than your likely time in the property is a no.
This is the arithmetic that settles the timing question, and it takes one line. Suppose a switch costs $1,100 all in, counting the discharge fee on the old loan, government registration fees and any application or valuation fees on the new one, and the new loan cuts repayments by $140 a month. Dividing 1,100 by 140 gives about 8, so the move pays for itself in roughly eight months, and every month after that is yours. The same method absorbs every complication: a break cost goes into the cost pile, a cashback comes off it, and the answer is always a number of months you can weigh against your own plans.
Moneysmart builds its switching guidance around the same test, and its mortgage switching calculator reports how long it takes to recover the cost of changing loans. Our refinance savings calculator runs the maths with your own numbers, and the plain English refinancing guide walks through a full worked example, costs table included.
According to Everstone Finance, the timing question has a boring answer: review the loan every year, act when the break-even maths says so. Divide total switching costs by the monthly saving; if the answer lands under a year, waiting for a better moment usually costs more than the move.
Frequently asked questions
Is there a minimum time between refinances in Australia?
No law sets a minimum time between refinances in Australia. The 6 to 12 month gap you often hear about is a market convention, not a rule: it reflects lender preferences and the way frequent applications read on a credit file. If a move clearly pays for itself sooner, the calendar is not the obstacle.
Does refinancing hurt your credit score?
Each application is recorded as an enquiry on your credit report, and several enquiries in a short window can make lenders more cautious. One considered refinance is routine for a healthy credit file. The pattern to avoid is scattergun applications to multiple lenders in quick succession, which is one reason the practical convention is to refinance deliberately rather than constantly.
Should you wait for the next RBA decision before refinancing?
Usually not. The Reserve Bank of Australia announces a cash rate decision after each of its scheduled Monetary Policy Board meetings, so there is always another decision to wait for. If the break-even maths already works at current pricing, waiting is just a slower way to pay more. And a variable rate keeps moving with the market after you switch, so a decision that lands later is not missed by moving first.
How often should you review your home loan?
Once a year as a habit, plus three natural checkpoints: the end of the financial year, each RBA cash rate decision, and the three months before a fixed term expires. A review is not a refinance. Most reviews end with either a repricing request to your current lender or a note to check again next year.
What does it cost to refinance a home loan?
Typical switching costs include a discharge fee from the outgoing lender, government fees to move the mortgage registration, and possible application or valuation fees on the new loan. On a fixed rate loan there may also be a break cost, which only your lender can quote. Moneysmart lists the same checklist. The total matters less than the break-even: divide it by the monthly saving to see how many months the switch needs to pay for itself.
Is it worth refinancing for a small rate difference?
Sometimes. The answer depends on the balance and how long you will keep the loan, not the size of the gap alone. A quarter of a percentage point on a large balance can be worth more in dollars than a bigger gap on a small balance. Run the break-even: if total costs divided by the monthly saving lands under 12 months and you plan to stay, the small gap is usually worth acting on.
The honest summary
Review the loan once a year and at the three natural checkpoints. Act when a trigger fires and the break-even lands under a year. Do not act because a calendar anniversary arrived, because a neighbour switched, or because a cashback advertisement found you at the right moment. And expect some reviews to end with you staying exactly where you are: a review that proves your loan is still competitive has done its job just as well as one that finds a saving. The only real mistake in all of this is the loan nobody has looked at for five years.
Timing sorted. Now run your numbers.
