Thinking About Leaving Your Current Home Loan? Understand the Costs First
Key Takeaways
Switching a standard variable loan usually costs $500 to $1,500 in exit and setup fees; the bigger swings come from LMI if your equity is under 20% and break costs if you leave a fixed rate early.
Work out your break-even by dividing total switching costs by your annual saving, then multiplying by 12; under a year is usually worth it, several years rarely is.
Ask the new lender to match your remaining loan term, since resetting to a fresh 30 years can add interest that cancels out the rate saving.
Try repricing with your current lender first: it costs nothing, carries no credit enquiry, and avoids every switching cost
Lower advertised rates and tempting cashback offers make switching home loans look like an easy win, and for plenty of borrowers it is. After several years of higher repayments, lenders are competing hard for refinancers, and the gap between what new customers are offered and what existing ones quietly pay can be worth real money. The catch is that leaving a loan is not free, and the headline saving you see in an ad is not the saving that lands in your pocket.
The honest question is not whether another lender has a lower rate. It almost always does. The question is whether the saving from switching will survive the discharge fees, government charges, possible lenders mortgage insurance, fixed-rate break costs, and the long-term effect of resetting your loan term. Sometimes it clears all of those with room to spare. Sometimes it does not, and you would be better off staying put or asking your current lender to sharpen your rate.
This article breaks down exactly what it costs to leave a home loan, how to work out your break-even point, and the lending factors that decide whether a switch is genuinely worth it. The goal is to help you make the call with your own numbers rather than a headline rate.
The quick answer: what it costs to leave a home loan
For a standard variable loan, the cost of switching is usually modest, often somewhere between $500 and $1,500 once exit and setup fees are added together. The bigger costs are the conditional ones: lenders mortgage insurance if your equity is under 20%, and break costs if you are leaving a fixed rate early. These can turn a clear saving into a marginal one.
So the sensible approach is to add up every cost that applies to your situation, compare it against your annual saving, and see how long it takes to get your money back. If you recover the costs quickly and stay ahead after that, switching makes sense. If the recovery period stretches out for years, it may not.
Why the lowest rate is not always the cheapest option
It is natural to compare loans by their interest rate, but the rate alone can be misleading. Two loans with the same rate can cost very different amounts once fees, features, and structure are taken into account, which is why the cheapest-looking loan is not always the cheapest loan to hold.
A few things can quietly erode the benefit of a lower rate:
An annual package fee of around $395 that offsets part of the rate saving.
A cashback that comes attached to a higher ongoing rate.
A loan term reset that lowers repayments but increases total interest over time.
Missing features, such as a full offset account, that were saving you interest on your old loan.
The comparison rate, which folds most fees into a single figure, is a better starting point than the advertised rate, but even that does not capture your personal costs to switch. That is where a proper break-even calculation comes in.
The costs to check before you switch
Before comparing any new loan, it helps to map out what leaving your current one will cost. These fees are not large individually, but together they set the bar your saving has to clear. The main ones fall into a few clear groups.
Exit costs from your current loan
When you leave, your current lender closes out the loan and releases its security over your property. This usually involves a discharge fee, often in the range of $300 to $400, plus a state government fee to remove the existing mortgage from your title. Neither is large, but both apply to almost every refinance.
Setup costs with the new lender
The new lender then establishes your loan and registers its mortgage over your property. Depending on the lender, this can include an application or settlement fee and a government registration fee, though many lenders waive their own fees to win refinancers. It is worth confirming which fees are charged and which are waived, because this varies a lot between lenders.
Valuation and equity checks
The new lender will value your property to confirm your equity and set your Loan-to-Value Ratio (LVR). This is often free, but it carries a hidden risk: if the valuation comes in lower than you expect, your LVR rises, which can affect your rate or push you into lenders mortgage insurance territory. Your current lender already knows your security, so a refinance is the point where valuation surprises tend to appear.
Ongoing package fees
Some loans sit inside a package that bundles features and offset accounts for an annual fee of around $395. A package can be worth it if you use the features, but if you are switching to chase a lower rate, factor the yearly fee into your comparison, because it eats into the saving every year, not just once.
Fixed-rate break costs explained
If any part of your loan is on a fixed rate, leaving before the term ends is the single biggest cost to check, because it can dwarf everything else. A break cost is not a fixed penalty; it is the lender recovering the loss it makes when you exit a fixed-rate agreement early.
The size of a break cost depends mostly on how interest rates have moved since you fixed and how much of your fixed term remains. If rates have fallen since you locked in, the break cost can be substantial. If they have risen or barely moved, it may be small. Because it is calculated on the day, the only way to know is to ask your lender for a written break cost figure before you decide anything.
For many fixed-rate borrowers, the smarter move is to time a switch for when the fixed term ends, avoiding the break cost entirely. If the saving from switching now is large enough to absorb the break cost and still come out ahead, it can still be worth it, but that is a calculation to run carefully rather than assume.
Why the 80% LVR mark matters for LMI
Lenders Mortgage Insurance (LMI) is a one-off cost that protects the lender, not you, when your loan is more than 80% of the property's value. It is one of the most common reasons a refinance that looks worthwhile on rate ends up not stacking up.
The key point for refinancers is that LMI generally cannot be transferred between lenders. If your equity is still below 20%, switching to a new lender can mean paying LMI a second time, and on a sizeable loan that can run into thousands of dollars, often wiping out years of rate savings in one hit. If you are in this position, asking your current lender to lower your rate instead avoids the issue, because staying put does not re-trigger LMI.
If your equity sits comfortably above 20%, this is not a concern, and you have access to the sharpest pricing. Knowing roughly where your LVR sits before you apply tells you quickly whether LMI is part of your calculation.
The hidden cost of resetting your loan term
This is the cost almost no one notices, because it does not appear as a fee. When you refinance, many loans default to a fresh 30-year term, which lowers your monthly repayment and makes the new loan feel cheaper. The trade-off is that stretching the remaining balance back out over 30 years can add a significant amount of interest over the life of the loan.
Imagine you are 8 years into a 30-year loan, so you have 22 years left. Refinancing into a new 30-year term drops your repayments, which feels like a win, but you have just added 8 years of interest back onto the loan. The lower repayment is real, yet the long-term cost can outweigh the rate saving entirely.
The fix is simple: ask the new lender to match your remaining term rather than restart at 30 years. You keep the rate saving without quietly extending the debt. If you do want lower repayments for cash-flow reasons, that is a valid choice, but it should be a deliberate one rather than an accident of the paperwork.
How to calculate your break-even point
The break-even point is the moment your accumulated savings overtake your switching costs. It is the clearest single test of whether a refinance is worth it, and the maths is not complicated.
Start with your annual saving, which is roughly your loan balance multiplied by the rate reduction. The table below shows the first-year interest saving for a couple of common loan sizes at different rate gaps.
Rate reduction
Annual saving on $500,000
Annual saving on $700,000
0.25%
$1,250
$1,750
0.50%
$2,500
$3,500
0.75%
$3,750
$5,250
To find your break-even, divide your total switching costs by your annual saving, then multiply by 12 to get the number of months. For example, a $500,000 loan switching to a rate 0.50% lower saves about $2,500 a year. If switching costs come to $1,000, you recover them in roughly five months ($1,000 divided by $2,500, times 12). Everything after that is genuine benefit.
Now flip it. The same $1,000 of costs against a 0.25% saving on $500,000, which is $1,250 a year, takes closer to ten months to recover, and that is before any package fee or break cost. The smaller the rate gap, the longer the recovery, and the more carefully you should look. A refinance with a break-even under a year is usually worth it; one that takes several years rarely is.
When switching is likely worth it
Switching tends to make sense when the saving is meaningful, the costs are low, and you can pass the new lender's assessment without trouble. It is most likely to stack up when several of these are true.
The rate gap is large enough that you recover the switching costs within a year.
Your equity is above 20%, so lenders mortgage insurance does not apply.
You are on a variable rate, or your fixed term is ending, so there is no break cost.
Your income is stable and your serviceability is comfortable.
You can keep your remaining loan term rather than resetting to 30 years.
When staying or repricing may be better
Sometimes the better financial move is to stay where you are and simply ask for a better deal. Repricing, which means requesting a lower rate from your current lender, costs nothing, carries no credit enquiry, and avoids every switching cost above. It is often the smarter first step when switching would be marginal or difficult.
The rate gap is small and would take years to recover after costs.
Your equity is under 20%, so refinancing could trigger LMI again.
You are mid-way through a fixed term with a meaningful break cost.
Your income has changed and you may not pass a new lender's serviceability test.
You are happy with your current loan's features and only want a sharper rate.
What lenders check when you refinance
It is easy to assume a refinance is approved on rate and equity alone, but the new lender assesses you as a fresh application. Understanding what they look at helps you judge whether approval is likely before you lodge anything.
The Australian Prudential Regulation Authority (APRA) expects lenders to test your repayments not at the actual rate, but at that rate plus a buffer, currently 3 percentage points. So even a comfortable repayment is assessed as though rates were higher. Lenders also shade some income: bonuses and overtime are often counted at around 80%, casual and variable income is treated cautiously, and the self-employed usually need one to two years of financials. Each application is a credit enquiry too, and several in a short period can affect your credit score. Some lenders apply a reduced buffer for straightforward, like-for-like refinances where you are not increasing the loan, which is one of the reasons matching the right lender to your situation matters.
Real borrower scenarios
The right decision depends on your rate, equity, loan type, and income. These four situations show how the same switch can land very differently.
Owner-occupier with strong equity
A borrower owes $450,000 on a home worth $750,000, sitting at a 60% LVR on a variable rate. A new lender offers 0.50% lower, saving about $2,250 a year against roughly $900 in switching costs. With no LMI, no break cost, and a break-even under five months, switching is clearly worth it, provided they keep their remaining loan term.
Borrower coming off a fixed rate
A borrower's three-year fixed term ends in two months. By timing the refinance for when the fixed period expires, they avoid any break cost entirely. Waiting those two months turns a questionable switch into a clean one, which is almost always better than breaking the fixed rate early and paying for the privilege.
Investor weighing a switch
An investor wants a lower rate but is also considering moving to interest-only repayments. Investor pricing and policy differ from owner-occupier loans, and the serviceability assessment is stricter. The rate saving is real, but the decision needs to weigh the structure and the lender's investor policy, not just the headline rate, so this is a case where modelling the full picture pays off.
Borrower with tighter serviceability
A borrower's hours were recently reduced, though their repayments remain comfortable. Tested at the buffered rate on lower income, a new lender may decline them, leaving an unnecessary credit enquiry behind. Repricing with their current lender is the safer way to secure a lower rate until their income recovers.
Common mistakes to avoid
Most refinancing regrets come from focusing on the rate and missing the details around it. These are the slip-ups worth guarding against.
Resetting the loan to a fresh 30-year term without realising the added interest.
Chasing a cashback that is attached to a higher ongoing rate or extra fees.
Forgetting to include the annual package fee in the comparison.
Refinancing on weak serviceability and collecting a decline plus a credit enquiry.
Rolling short-term debts, like a car loan, into a 30-year mortgage and paying far more over time.
Assuming the advertised rate applies, when your LVR may place you in a different pricing band.
How a mortgage broker can help
A broker's value here is mostly about doing the full comparison properly and reducing the risk of a wasted application. Because they work across many lenders, they can see the wider market and find the lender whose pricing and policy genuinely suit you.
In practice, a broker can benchmark your current loan against a range of lenders, approach your existing lender to reprice on your behalf, and check your borrowing capacity before lodging anything, so you avoid unnecessary credit enquiries. They can also model your break-even point including every cost, factor in LMI or break costs where they apply, and structure the new loan to keep your remaining term rather than resetting it. For borrowers unsure whether a switch is even worth the effort, that early modelling answers the question before any paperwork is signed.
If you want to understand whether switching will genuinely leave you better off, speaking with a mortgage broker in Albury & Wodonga can help you compare the full cost of refinancing before you apply. This is especially useful if you need to factor in break costs, lenders mortgage insurance, loan term changes, or whether your current lender could simply offer a sharper rate.
Frequently Asked Questions (FAQs)
Should I ask my current lender for a better rate first?
Usually yes. Asking your current lender to lower your rate, known as repricing, costs nothing and does not involve a credit enquiry. If they match or get close to the market, you save without paying any switching costs. If they will not budge, you can then weigh up refinancing knowing you have already tried the easy option.
What is a discharge fee?
A discharge fee is what your current lender charges to close your loan and release its mortgage over your property when you leave. It is typically a few hundred dollars and applies to almost every refinance, alongside a small state government fee to remove the old mortgage from your title.
Will I pay lenders mortgage insurance again if I refinance?
You might, if your loan is still more than 80% of your property's value. Lenders mortgage insurance generally cannot be transferred between lenders, so switching while your equity is under 20% can mean paying it a second time. If that applies to you, repricing with your current lender avoids the cost entirely.
Does refinancing affect my credit score?
Each refinance application is recorded as a credit enquiry, and several enquiries in a short space of time can have an effect. This is why it helps to compare options and check your likely approval before lodging, rather than applying to multiple lenders at once. Repricing, by contrast, does not usually involve an enquiry.
Can refinancing increase my total interest?
It can, even with a lower rate, if you reset the loan back to a fresh 30-year term. Lower repayments feel like a saving, but stretching the balance over a longer period adds interest over time. Asking the new lender to match your remaining term keeps the rate saving without extending the debt.
What happens to my offset account when I switch?
Your offset account does not move with you. Before settlement, you withdraw any offset or redraw funds and direct them where you want them, often into the new loan or a new offset account. If your offset balance was saving you meaningful interest, check that the new loan offers a comparable offset, since losing that feature can reduce the benefit of a lower rate.
How long does refinancing usually take?
A straightforward refinance commonly takes a few weeks from application to settlement, depending on the lender, the valuation, and how quickly documents are provided. Repricing is far faster, often resolved within a few days, which is another reason it can be worth trying first.
The Bottom Line
Leaving your home loan can save you a lot, but only once the saving has cleared the discharge fees, setup costs, any lenders mortgage insurance, fixed-rate break costs, and the long-term effect of your loan term. The number that matters is not the advertised rate; it is how quickly you recover your switching costs and how far ahead you stay after that.
Work out your break-even with your own figures, keep your remaining loan term rather than resetting it, and ask your current lender for a better rate before you commit to moving. If the saving survives all of that with room to spare, switching is a sound move. If it does not, staying put or repricing may leave you better off.
