The Cost of Refinancing a Home Loan in Australia (2026): Every Fee, and the Break-Even Maths
Refinancing a home loan in Australia typically costs somewhere in the hundreds to low thousands of dollars in fees: a discharge fee from your old lender, government registration fees that vary by state, and any setup and valuation costs the new lender charges, many of which are routinely waived to win the loan. The two costs that can change the picture are break costs, if you are leaving a fixed rate early, and lenders mortgage insurance, if you refinance above 80 per cent of your property’s value. The maths that matters is break-even: how many months of savings repay the cost of the move.
- Routine fees are small against the balance of a mortgage, and lenders often waive their own to win you.
- Break costs are the wildcard: leaving a fixed rate early can cost real money, and the quote is free.
- The 80 per cent line matters: refinancing above it can trigger lenders mortgage insurance again, which usually kills the case.
- Break-even is the decision: cost of the move divided by monthly saving equals months to repay the switch; after that every month is profit.
- Waiting has a cost too: a loan drifting a quarter of a percentage point above the market on $600,000 quietly costs about $1,500 a year, more than the routine fee stack.
- Timing beats breaking: a fixed rate expiry can be tested a month ahead and the switch settled the week the fixed rate ends, break cost avoided entirely.

What does refinancing a home loan cost? The full stack, itemised
The cost of refinancing a home loan in Australia is a stack of small items: a discharge fee from the current lender, state government mortgage registration and discharge fees (a few hundred dollars in total for most), and the new lender’s application, settlement and valuation fees, which are frequently waived. Moneysmart lists the same switching costs.
| Cost | Who charges it | What to know |
|---|---|---|
| Discharge fee | Your current lender | A fixed administrative fee for closing the loan |
| Mortgage registration and discharge | State government | Set by each state’s land registry; a few hundred dollars in total for most |
| Application or settlement fee | The new lender | Frequently waived on refinances; always ask |
| Valuation | The new lender | Often free on standard properties |
| Package or annual fee | The new lender | Recurring; belongs in the comparison, not the fine print |
| Break costs | Your current lender | Only if leaving a fixed rate early; see below |
| Lenders mortgage insurance | The new lender’s insurer | Only above 80 per cent LVR; usually decisive |
Two structural notes. Fees paid once compete against savings that recur monthly, which is why small fee stacks rarely decide the question. And a lender’s own fees are negotiable in a way government charges are not; a broker asks as a matter of routine.
What are break costs, and when do they apply?
Break costs apply only when you leave a fixed rate home loan early. The lender funded the fixed rate at fixed cost, so leaving can leave it out of pocket, and the size depends on your balance, the time remaining and how rates have moved since you fixed, from nothing to decisive money. Your lender must quote it, free, on request.
Fixed rate loans are funded at fixed cost, so leaving one early can leave the lender out of pocket, and they pass that on as a break cost. The size depends on your balance, the time remaining, and how rates have moved since you fixed; it ranges from nothing to genuinely decisive money. The number is knowable before you commit: your lender must quote it on request, the quote is free, and our break costs guide and calculator explains how the figure is built and estimates yours.
What is the 80 per cent trap?
The 80 per cent trap is lenders mortgage insurance paid twice. LMI paid on the original loan does not transfer, so refinancing above 80 per cent of the property’s current value means the new lender’s insurer charges its own premium, which usually erases years of rate savings. Refinance once the loan sits at or under 80 per cent of current value.
Lenders mortgage insurance paid on your original loan does not transfer. Refinance above 80 per cent of your property’s current value and the new lender’s insurer wants its own premium, which usually erases years of rate savings in one line item. The clean answer is to refinance once your loan sits at or under 80 per cent of current value, a line that rising values and steady repayments may already have carried you past without you noticing. It is the first thing we check.
How do you work out the break-even on a refinance?
The break-even on a refinance is one division: the true cost of the move, fees plus any break cost, divided by the monthly saving, equals the months until the switch has paid for itself. A move costing $1,200 that saves $250 a month breaks even inside five months; $9,000 in break fees for the same saving needs three years.
The whole decision compresses into one division. Add up the true cost of the move: fees plus any break cost. Divide by the monthly saving the new loan delivers. The result is the number of months until the switch has paid for itself; everything after is profit. A move that costs $1,200 and saves $250 a month breaks even inside five months on a loan you will hold for years. A move that costs $9,000 in break fees to save the same $250 needs three years just to catch up, and deserves harder questions.
The refinance savings calculator runs the savings side on your actual balance, and our five minute loan self-audit is the fastest way to find out whether the question is even live for you. If the answer leans toward staying, our guide to repricing with your own bank versus switching covers the move that costs nothing at all.

Two files, side by side
Two illustrative files show the arithmetic deciding differently. A variable-rate file costing $1,100 in routine fees with a $260 monthly saving breaks even in just over four months, so it moves. A mid-fixed-term file with the same fees plus an $8,000 break cost needs about 35 months, so it usually waits out the fixed term and diarises the expiry.
| Variable-rate file | Mid-fixed-term file | |
|---|---|---|
| Cost to move | $1,100 in routine fees | $1,100 in fees plus an $8,000 break cost |
| Monthly saving on offer | $260 | $260 |
| Break-even | Just over 4 months | About 35 months |
| The call | Move; every month after month five is profit | Usually wait out the fixed term, and diarise the expiry |
Neither answer is about courage or loyalty; both fall straight out of the division. The second file’s owner is not stuck, either: the expiry date is known, the market can be tested a month ahead, and the switch can settle the week the fixed rate dies, break cost avoided entirely.
What do you need to refinance? The ten minute checklist
To refinance a home loan you need five things: identity documents, income evidence (recent payslips and a tax summary for employees, more history when self employed), recent statements for the mortgage and any other debts, a rates notice for the property, and the fixed rate expiry date if you have one. Gathering these is the largest share of your effort.
- Identity: the usual documents, once.
- Income: recent payslips and a tax summary for employees; more history when self employed.
- The loan: recent statements for the mortgage and any debts riding along.
- The property: a rates notice; the lender orders its own valuation.
- The expiry date, if fixed: it drives the whole timetable.
Gathering this is genuinely the largest share of the borrower’s effort in a refinance. Everything after it is signatures and waiting.
What does waiting to refinance cost?
Waiting to refinance has a cost that no fee table itemises. A loan drifting a quarter of a percentage point above the market on a $600,000 balance quietly costs about $1,500 a year, more than the routine fee stack for a refinance, every year the drift persists. The most expensive line item is usually the years before the switch.
Every table above prices the move. Nothing prices the not-moving, so do it here: a loan drifting a quarter of a percentage point above the market on $600,000 quietly costs about $1,500 a year, more than the routine fee stack for a refinance, every single year the drift persists. The most expensive line item in refinancing is usually the years before it, which is why the five minute self-audit exists and why the loyalty mechanics get a full airing in our complete refinance guide.
Is zero cost refinancing real?
Zero cost refinancing is real: it usually means the new lender’s incentives, waived fees or a cashback offer, cover the visible cost stack. The discipline is that the incentive is the sweetener, not the meal; a cashback attached to an uncompetitive rate is a payment for accepting drift, and the break-even maths exposes it in seconds.
Zero cost refinancing usually means the new lender’s incentives, waived fees or a cashback offer, cover the visible cost stack. Real, and worth having, with one discipline: the incentive is the sweetener, not the meal. A cashback attached to an uncompetitive rate is a payment for accepting drift, and the break-even maths above exposes it in seconds. Judge the loan first, the incentive second.
How long does refinancing take?
A clean home loan refinance typically takes a few weeks end to end: days for approval when the file is tidy, then the discharge and settlement process between the two lenders, which is the slow half. Plan a fixed rate expiry about a month ahead so the new loan starts the day the old rate ends.
A clean refinance typically runs a few weeks end to end: days for approval when the file is tidy, then the discharge and settlement dance between lenders, which is the slow half. Your effort is front-loaded into gathering documents and one conversation; after approval it is mostly waiting while the banks talk to each other. Fixed-rate expiries are worth planning a month or so ahead, so the new loan starts the day the old rate ends, a timing move our fixed rate expiry guide covers.
Questions people actually ask
Is it worth refinancing for a small rate difference?
Run the division. Even modest monthly savings repay a small fee stack quickly on a large balance, and the years after break-even are pure gain. The answer is arithmetic, not opinion.
What does refinancing cost if I am not on a fixed rate?
Usually just the routine stack: discharge, government fees, and whatever the new lender does not waive. For most variable-rate borrowers the total is modest against the saving.
Can refinancing cost me nothing?
Effectively yes, when waived fees and incentives cover the stack, and genuinely yes if you reprice with your current lender instead of moving. The second option is underrated and takes one phone call, or one from us.
Do I pay lenders mortgage insurance again when I refinance?
Only if the new loan sits above 80 per cent of the property’s current value. LMI paid on your original loan does not transfer, so a refinance above that line means a fresh premium from the new lender’s insurer, which usually erases years of rate savings. At or under 80 per cent, no.
How long does refinancing take in Australia?
Commonly a few weeks from application to settlement, faster with a complete file, slower when discharges queue at the outgoing lender.
What are the government fees to refinance a home loan?
State government mortgage registration and discharge fees, set by each state’s land registry, which come to a few hundred dollars in total for most refinances. They are not negotiable, unlike a lender’s own application, settlement and valuation fees, which are frequently waived to win the loan.
How do I work out the break-even on a refinance?
Add up the true cost of the move, fees plus any break cost, and divide by the monthly saving the new loan delivers. The result is the number of months until the switch has paid for itself. A move costing $1,200 that saves $250 a month breaks even inside five months.

Map my break-even, freeWhat are the costs associated with refinancing a mortgage?
A stack of small items rather than one big fee: a discharge fee from your current lender, state government mortgage registration and discharge fees that come to a few hundred dollars in total for most borrowers, and the new lender application, settlement and valuation fees, which are frequently waived on a refinance. Add a package or annual fee if the new loan carries one, a break cost only if you leave a fixed rate early, and lenders mortgage insurance only if the new loan is above 80 per cent of the valuation.
