What Are Break Costs on a Fixed-Rate Home Loan, and How Are They Calculated?
A break cost is compensation for the lender’s loss, not a penalty, and exit fees on home loans have been banned since 2011 with break costs as the named exception. The lender is not obliged to show you its cost of funds. AFCA publishes exactly how it checks the number anyway, which means a break cost is not unauditable, it is just not audited by you.
The short answer
A break cost is the lender’s compensation for the loss it incurs when you exit a fixed rate early. It is calculated from the movement in wholesale interest rates between the term you originally fixed for and the remaining term at the time you repay, applied to the amount repaid and adjusted for the time value of money. If wholesale rates have risen since you fixed, the break cost is usually small or nil. If they have fallen, it can be material. Exit fees on residential loans have been prohibited since 1 July 2011, and break costs are the specific exception.
Why a break cost is not an exit fee
Most people meet the term break cost while suspecting they are being fined for changing their mind. They are not, and the distinction is a legal one rather than a matter of framing.
Since 1 July 2011, regulation 79A has prohibited early termination fees on residential loans where any of the credit is secured over residential property. The old deferred establishment fees, the ones that made switching expensive for the sake of making switching expensive, are gone. ASIC’s Regulatory Guide 220 sets out that prohibition and also sets out what it does not reach: at RG 220.26, the prohibition does not apply to a break fee, a discharge fee, or a credit fee or charge incurred before termination.
So a break cost is not a survival of the old exit fee regime. It is a specifically carved out category, and the reason it survives is that it compensates for a real loss rather than deterring you from leaving.
The loss is genuine. When a lender writes a fixed rate loan, it funds that commitment in wholesale markets and locks in its own cost for the term. That match is the entire product: you get repayment certainty, the lender gets margin certainty. Repay early and the lender’s funding commitment does not evaporate with your loan. If wholesale rates have moved against it in the meantime, it is left holding funds that cost more than it can now re-lend them for. That gap is the loss a break cost recovers.
Exit fees were banned because they punished leaving. Break costs survived that ban because they price a loss that actually happens.
Where your loan is regulated by the National Credit Code, that compensation is capped in substance as well as principle. AFCA states that the Code provides a break cost should not exceed a reasonable estimate of the loss suffered by the lender. Code regulated loans include consumer fixed rate loans secured by residential property. Loans outside the Code, which AFCA gives as including commercial loans, commercial bill finance and market linked fixed rate small business loans, do not get that protection, and there the only test is what the contract permits.
How the calculation actually works
Lenders calculate break costs from the movement in their own cost of funds, and AFCA accepts that how a lender determines that cost is commercially sensitive and that it is under no obligation to disclose it to you. That is the honest position and it is why no calculator on the internet can give you your number.
What AFCA does publish is the method it uses to independently verify whether the lender’s figure is reasonable, and that method is the closest thing to an official formula that exists. It compares two wholesale market interest rates:
- The fixed term wholesale market rate for the term you originally fixed for.
- The fixed term wholesale market rate for the term remaining at the time you repay. AFCA’s own worked example: a 5 year fixed loan repaid after 2 years, so 3 years early, is checked against the 3 year wholesale rate.
That second point is the technical detail almost every explanation gets wrong. The comparison is not today’s 5 year rate against the 5 year rate you fixed at. It is the rate for the time you have left. Because the swap curve is not flat, different maturities price differently, and a loan with 3 years remaining is checked against a different point on the curve than one with 1 year remaining.
The movement between those two rates is then applied, and AFCA states its assessment also takes into account the amount repaid, the remaining term of the original fixed contract, the contracted repayments, and the time value of money. In plain terms:
| Input | Effect on the break cost |
|---|---|
| Direction of wholesale rates since you fixed | The dominant factor. Rates lower now than when you fixed means a real loss and a material cost. Rates higher means little or no loss, and often nil |
| Amount repaid | Proportional. The same rate movement on a larger balance produces a larger dollar figure |
| Remaining fixed term | Longer remaining term means more exposure. Costs are typically highest early in the fixed period and fall as it runs down |
| Time value of money | A present value adjustment, because the lender receives the compensation now rather than spread across the remaining years |
The shape of it, then, is the amount you repay multiplied by the adverse rate movement multiplied by the years remaining, discounted to today. Everything else is detail.

Direction of rates decides everything
The counter-intuitive part of break costs is that the level of rates is close to irrelevant. What matters is which way they have moved since you signed.
If wholesale rates for your remaining term are higher now than when you fixed, the lender can re-lend the money more profitably than your loan was providing. There is no loss to recover, and the break cost is commonly minimal or nil. If they are lower, the lender is left funding at a cost it can no longer earn, and the break cost is real.
Which makes the recent cash rate path worth understanding, because it has gone out and come back. These are the Reserve Bank’s published cash rate targets, which are a policy rate rather than any lender’s product rate, but they set the tone the wholesale curve prices against.
| Date | Move | Cash rate target |
|---|---|---|
| Nov 2020 to Apr 2022 | Held at the pandemic floor | 0.10% |
| 4 May 2022 | First increase of the cycle | 0.35% |
| 8 Nov 2023 | Peak, after 13 increases | 4.35% |
| 19 Feb, 21 May, 13 Aug 2025 | Three reductions | 4.10%, then 3.85%, then 3.60% |
| 4 Feb, 18 Mar, 6 May 2026 | Three increases | 3.85%, then 4.10%, then 4.35% |
| 17 Jun and 12 Aug 2026 | Held | 4.35% |
The shape that matters is the round trip. The cash rate peaked at 4.35 per cent in November 2023, was reduced across 2025 to 3.60 per cent, and was returned to 4.35 per cent by three increases in the first half of 2026, where it has since been held. It is now back at its cycle peak.
Two practical consequences follow, and they are close to the opposite of the advice that circulated during the fixed rate boom:
- If you fixed while rates were low, the direction has been against the lender’s loss, not yours. Anyone who fixed during the 2025 easing, or earlier at the pandemic floor, is looking at wholesale rates for their remaining term that are higher than the ones they locked in. On the standard method, that produces little or no recoverable loss.
- The exposure now sits with anyone fixing at the top. A borrower fixing while the cash rate sits at its cycle peak is the borrower who would face a material break cost if rates were subsequently reduced. That is not a prediction about rates, which we do not make. It is simply where the risk lies, and it is worth knowing before you fix rather than after.
The general lesson is that a break cost is a function of the rate cycle rather than of your lender’s attitude, and the same lender will quote you nil in one environment and a large number in another for an identical loan.
How to check a break cost you have been quoted
Only your lender can produce the exact figure, because only your lender knows its funding curve. That is usually where articles on this topic stop, which leaves borrowers thinking the number is simply unauditable. It is not.
AFCA has published both the method above and the reference rates it uses: for fixed terms of 1 to 5 years it references the fixed term wholesale market rates published daily in the Australian Financial Review under swap rates quarterly in arrears, and for terms longer than 5 years it uses the relevant swap rate published daily by the Australian Financial Markets Association. Those are public reference points. A borrower who knows the original term, the remaining term and the amount repaid can therefore form a view about whether the shape of the number is plausible, even without the lender’s internal curve.
The practical sequence:
- Ask for the quote in writing. It should state the dollar figure, the date and time of calculation, and how long it is valid. Verbal figures are not reliable, and AFCA notes that a lender’s cost of funds can vary significantly day to day, so quotes are short lived by nature.
- Ask what is included. Some lenders add a separate break administration fee on top of the economic cost. You want the all-in number.
- Check the terms used. Confirm the calculation compares your original fixed term against your remaining term, which is the basis AFCA applies.
- Repay first and dispute later if you need to. AFCA states that repaying the loan does not prevent a customer lodging a complaint about whether the break cost was properly incurred, and that where it concludes an amount was charged incorrectly it will require that amount to be refunded. You do not have to choose between settling on time and preserving your position.
- Know what AFCA will and will not look at. It generally will not review the level of a fee as such. It will consider whether the fee was properly disclosed, charged in accordance with your contract, and correctly applied, and for a Code regulated loan whether it exceeds a reasonable estimate of the lender’s loss.
What sits outside the break cost
The break cost is one line on a larger bill, and the other lines apply whether you are in a fixed term or not.
| Cost | Inside the break cost? |
|---|---|
| Economic loss on the fixed funding | Yes. This is the break cost |
| Break administration fee | No, where a lender charges one it is separate. Ask for it in the quote |
| Discharge fee | No. Charged to remove the mortgage from title, and applies to fixed and variable loans alike |
| Mortgage registration and land registry fees | No. Set by the state, and payable on discharging and registering a mortgage |
| New lender establishment costs | No. Application, valuation and settlement charges, plus any mortgage insurance if the new loan crosses 80 per cent of value |
Two other situations trigger a break cost that people do not expect. Repaying more than your loan’s annual extra repayment allowance can trigger one on the excess, which matters before you direct a bonus or an inheritance at the mortgage. And selling the property inside the fixed term is an early exit like any other, settled as an adjustment out of the proceeds.
Whether paying a break cost is worth it is a payback calculation rather than a break cost question, and we have set that out separately in how much you can realistically save by refinancing. The short version is that you divide the total switching cost, break cost included, by the monthly saving, and compare the resulting number of months against how long you actually expect to hold the loan.
How Intellect Finance can help
Where we are useful on this is narrow and worth being honest about. We cannot calculate your break cost and neither can anyone other than your lender. What we do is request the quote on your behalf, check that it has been calculated on the right terms, work out what a switch would need to save for the number to be worth paying, and tell you when the answer is to wait until the fixed period ends rather than move now. We compare over 100 lenders and find the one that fits your situation. Often the recommendation is to do nothing for a few months, which is not a transaction for us, and it is still the right advice. Our refinance home loan page covers the switching process itself.
A home loan for a property you will live in is regulated consumer credit under the National Consumer Credit Protection Act 2009, and Best Interests Duty applies. We charge you nothing on any loan type, with no arrangement fee and no clawback recovery fee. Penrith based since 2005, holding Australian Credit Licence 390611.

Frequently Asked
Break Cost FAQs
What borrowers ask most about exiting a fixed rate early.
What are break costs on a fixed-rate home loan?
They are the lender’s compensation for the loss it suffers when a fixed rate loan is repaid or partly prepaid early. The lender funded your fixed rate in wholesale markets for the full term, and if rates have moved against it, it cannot re-lend the money on the same terms. The break cost recovers that gap.
Is a break cost the same as an exit fee?
No. Early termination fees on residential loans have been prohibited since 1 July 2011 under regulation 79A. ASIC’s Regulatory Guide 220 confirms at RG 220.26 that the prohibition does not apply to a break fee, a discharge fee, or a charge incurred before termination. A break cost is the carve-out, because it prices a real loss.
How is a break cost calculated?
From the movement in wholesale interest rates between the term you originally fixed for and the term remaining when you repay, applied to the amount repaid and adjusted for the time value of money. AFCA’s example: a 5 year fixed loan repaid 3 years early is checked against the 3 year wholesale rate, not the 5 year rate.
Why is my break cost zero?
Because wholesale rates for your remaining term are higher now than when you fixed, so the lender suffers no loss by having the money back early. It can re-lend at better terms than your loan provided. When rates have risen since you fixed, a nil or minimal break cost is the normal outcome rather than a lucky one.
Can I dispute a break cost?
Yes, and repaying the loan first does not prevent it. AFCA states that a customer who repays can still lodge a complaint about whether the break cost was properly incurred, and that where it finds an amount was charged incorrectly it will require a refund. It considers disclosure, contract compliance, correct application, and for Code regulated loans the reasonable estimate test.
Does my lender have to show me how it calculated the figure?
No. AFCA accepts that how a lender determines its cost of funds is commercially sensitive and that it is under no obligation to disclose it. What is public is AFCA’s own verification method and the reference rates it uses, published daily in the Australian Financial Review for terms of 1 to 5 years and by AFMA for longer terms.
Do break costs apply if I sell the house?
Yes, if the loan is discharged inside the fixed period. A sale is an early exit like any other and the break cost is settled as an adjustment out of the sale proceeds. Get the quote before you commit to a settlement date, because the figure moves and the quote is usually valid only briefly.
Can extra repayments trigger a break cost?
They can. Fixed loans commonly cap how much extra you may repay each year, and repayments above that allowance can trigger a break cost on the excess because a partial prepayment creates the same funding mismatch as a full one. Check your contract before directing a bonus, inheritance or sale proceeds at a fixed loan.
Are break costs capped by law?
For loans regulated by the National Credit Code, AFCA states the Code provides that a break cost should not exceed a reasonable estimate of the lender’s loss. Consumer fixed rate loans secured by residential property are within the Code. Loans outside it, such as commercial lending, do not get that protection, and the contract governs instead.
Is it worth breaking a fixed loan to refinance?
It depends on the payback period. Divide the total switching cost, including the break cost, discharge and new lender fees, by the monthly saving, then compare that number of months against how long you expect to hold the loan. Within a few months of your fixed term ending, waiting is usually the better answer.
The bottom line
A break cost is not a penalty and it is not arbitrary. It is a loss calculation driven almost entirely by which way wholesale rates have moved since you fixed, and it is one of the few charges in Australian home lending that survived the 2011 ban on exit fees, precisely because it prices something real.
The part worth holding onto is the asymmetry. Fixing protects you from rate rises, and if rates rise you can also leave cheaply, because the lender loses nothing by having the money back. Fixing exposes you to break costs only when rates fall, which is the same scenario in which you most want to leave. The product does not fail you at random. It fails you in exactly one direction, and the cash rate sitting back at its cycle peak is a reasonable moment to notice that before signing a new fixed term rather than after.
If you have a quote in hand, the number is checkable in shape even though the lender’s own curve is not published, and repaying does not forfeit your right to question it later.
