Costs of Refinancing a Home Loan in Australia and How to Estimate the Break-Even Point

The information on this website is general in nature and does not take into account your objectives, financial situation, or needs. Consider seeking personal advice from a licensed adviser before acting on any information.

Refinancing a home loan can look attractive when another lender offers a lower rate, better loan features or a structure that suits your current goals. But the headline interest rate is only one part of the decision. To work out whether refinancing may be worthwhile, Australian homeowners need to compare the likely benefits with the costs of switching.

This guide explains common refinance costs in Australia, how comparison rates may help, and a potential way to estimate the home loan break-even point: the time it may take for repayment savings to offset upfront refinancing fees. It is general information only and does not consider your objectives, financial situation or needs.

Why refinancing costs matter

A lower interest rate does not automatically mean a better overall outcome. Refinancing may involve exit, application, valuation, settlement and government-related costs. A new loan may also have different ongoing fees, loan features, repayment terms or conditions.

For example, a lower rate may reduce your monthly repayment, but if the upfront costs are high and you plan to sell the property soon, you may not hold the new loan long enough to recover those costs. On the other hand, if the ongoing savings are meaningful and the new loan suits your needs, the costs may be easier to justify over time.

Common costs of refinancing a home loan in Australia

Refinance costs vary between lenders, loan products, property types and borrower circumstances. Some lenders may waive certain fees or offer incentives from time to time, while others may charge fees that are not obvious from the advertised rate. Always check the loan contract, credit guide, fee schedule and discharge information before deciding.

Discharge fee from your current lender

A discharge fee, sometimes called a mortgage discharge or settlement fee, may be charged by your existing lender when your current loan is paid out and the mortgage is released. This is separate from any costs charged by the new lender.

Ask your current lender for a written payout figure and a list of discharge costs. The payout amount may include accrued interest up to settlement, fees and any other amounts required to close the loan.

Break costs on a fixed rate loan

If you refinance during a fixed rate period, your current lender may charge break costs. These can be significant and are calculated using the lender’s methodology, which may take into account factors such as the fixed rate, remaining fixed term, wholesale funding conditions and the rate the lender can relend at.

Break costs can change over time and may be different on the day you settle compared with an earlier estimate. If you have a fixed rate loan, request a current break cost estimate before applying and ask how long that estimate is valid.

Application, establishment or approval fee

The new lender may charge an application, establishment or approval fee for setting up the new loan. Some lenders include these fees as part of a package, while others charge them separately.

Do not make assumptions about things, such as 'a no-application-fee loan is automatically cheaper overall'. Compare the interest rate, ongoing fees, features and total cost over the period you expect to keep the loan.

Valuation fee

The new lender may need to value the property before approving the refinance. Depending on the lender and the property, this could be an automated valuation, desktop valuation or physical valuation. A valuation fee may apply, although some lenders absorb or waive this cost.

The valuation can also affect the loan-to-value ratio, commonly known as LVR. If the lender values the property lower than expected, your borrowing position, available equity or loan approval options may change.

Settlement, legal and conveyancing-related fees

Refinancing involves paying out the old loan and registering the new lender’s mortgage. Settlement or legal-related fees may be charged by the new lender, the outgoing lender or a settlement provider. These costs can vary depending on the transaction and lender process.

If you are refinancing and also changing property ownership, consolidating debts or altering the loan structure in a more complex way, you may need additional professional advice.

Government registration fees

State or territory land title offices generally charge fees to register and discharge mortgages. The amount and process can vary by jurisdiction and transaction type. These are not usually controlled by the lender, although the lender or settlement agent may collect them as part of settlement.

Lenders mortgage insurance

Lenders mortgage insurance, or LMI, may apply if your new loan is considered higher risk by the lender, often because the LVR is above the lender’s threshold. LMI protects the lender, not the borrower.

If you paid LMI on your original loan, it usually does not automatically transfer to a new lender when you refinance. This means refinancing at a high LVR may trigger a new LMI cost. The size of this cost depends on lender criteria, loan amount, LVR and other factors.

Package, annual and ongoing loan fees

Some home loans have annual package fees, monthly account fees or fees linked to offset accounts, redraw, split loans or other features. These costs can reduce or outweigh savings from a lower rate.

When comparing mortgage refinancing fees, separate one-off switching costs from ongoing costs. A loan with a small upfront saving but higher annual package fees may not suit every borrower.

Rate lock fees

If you are applying for a fixed rate loan, some lenders may offer a rate lock option for a fee. This may protect the approved fixed rate for a set period, subject to the lender’s terms. Whether it is worthwhile depends on the fee, the likelihood of rate movement, settlement timing and your preferences.

Cashback clawbacks or special offer conditions

If your existing loan included a cashback or special offer, check whether there are clawback conditions if you refinance within a certain period. Similarly, if the new loan includes an incentive, read the terms carefully so you understand eligibility requirements, timing and any conditions that could affect the benefit.

Costs that are easy to overlook

Beyond lender fees, refinancing can have practical and financial effects that are easy to miss. Consider whether any of the following apply:

• Loss of offset or redraw benefits: If the new loan has different features, the day-to-day impact on interest, cash flow and flexibility may change.
• Interest adjustments at settlement: Your payout figure may include interest calculated to the settlement date.
• Longer loan term: Extending the term can reduce repayments but may increase total interest over the life of the loan if you do not make extra repayments.
• Debt consolidation risks: Rolling shorter-term debts into a home loan may reduce monthly repayments but can cost more over a longer term and puts the debt against your home.
• Investment property tax treatment: If the loan relates to an investment property, refinancing costs and interest treatment may have tax implications. Consider speaking with a registered tax adviser.

How the comparison rate helps when refinancing

The comparison rate is designed to show the cost of a loan by combining the interest rate with certain fees and charges, based on a standardised loan amount and term. It can be useful because it highlights that two loans with the same advertised rate may have different overall costs.

However, the comparison rate has limitations. It may not include all costs that matter to you, such as government charges, break costs, redraw fees, offset account value, cashback conditions or the way you actually use the loan. It is also based on assumptions that may not match your loan size, remaining term or repayment behaviour.

Use the comparison rate as a screening tool, not as the only basis for choosing a refinance option.

How to estimate your home loan break-even point

The home loan break-even point is the estimated time it takes for savings from refinancing to recover the upfront costs of switching. It is not a guarantee, but it can help you decide whether a refinance option deserves closer review.

A simple formula is:

Break-even period = total upfront refinancing costs ÷ estimated monthly saving

For example, if refinancing costs were $2,000 and the estimated repayment saving was $100 per month, the simple break-even period would be 20 months. This means you would need to keep the new loan for around 20 months before the monthly savings offset the upfront costs, assuming the savings stay the same and no other costs or changes apply.

This calculation is intentionally simple. It does not capture every factor you may need to consider, but it gives you a starting point for comparing options.

Step 1: Add up the likely upfront costs

Ask both the outgoing and incoming lender for a detailed list of fees. Include costs such as:

• discharge or payout fees from your current lender;
• fixed rate break costs, if applicable;
• application, establishment or approval fees;
• valuation fees;
• settlement or legal-related fees;
• government mortgage registration and discharge fees;
• new LMI, if applicable; and
• any other switching costs or clawbacks.

Where a cost is only an estimate, use a conservative figure so you are not relying on an overly optimistic result.

Step 2: Estimate the repayment difference

Compare your current repayments with the likely repayments under the new loan. Make sure the comparison is fair. Differences in loan amount, remaining term, fixed or variable rate, repayment type and offset use can all change the result.

A calculator can help you test different repayment assumptions. You can use a home loan calculator to model how changes in rate, loan term or repayment amount may affect the result. Treat the output as an estimate only, because actual repayments depend on lender approval, product terms and future rate movements.

Step 3: Compare the break-even period with your plans

Once you have an estimated break-even period, compare it with how long you expect to keep the loan. If you may sell, move, refinance again or make major changes soon, a long break-even period may reduce the benefit of switching.

If you expect to keep the loan for longer, the break-even period may be more useful, but it should still be considered alongside loan features, flexibility, risk and total interest over time.

Step 4: Check the total cost, not just monthly cash flow

Lower monthly repayments can be helpful, but they can also occur because the loan term has been extended. A longer term may mean paying interest for more years. If your goal is to save interest, compare the estimated total interest under each option, not only the immediate repayment.

Some borrowers refinance to shorten the loan term while keeping repayments similar. Others refinance to improve cash flow. The right focus depends on your circumstances and goals.

A practical refinance cost checklist

Before applying, consider asking these questions:

• What is the full payout figure for my current loan?
• Will my current lender charge a discharge fee or break costs?
• What fees will the new lender charge upfront?
• Will a valuation be required, and could it affect my LVR?
• Will I need to pay LMI again?
• Are there annual, package or monthly fees on the new loan?
• Does the new loan include offset, redraw or repayment flexibility that I will actually use?
• Does the comparison rate tell a different story from the advertised rate?
• How long is the estimated break-even period?
• Could extending the term increase my total interest cost?
• Are any cashback offers or incentives subject to conditions?

When refinance costs may outweigh the benefits

Refinancing may be less attractive if the costs are high, the repayment saving is small, or you are unlikely to keep the loan long enough to break even. It may also be unsuitable if the new loan removes features you value or encourages you to stretch debt over a longer term without a clear reason.

Be especially cautious if the main benefit is a short-term incentive rather than a sustainable loan structure. Cashback or introductory offers can be useful in some situations, but they should not distract from the ongoing rate, fees, loan term and conditions.

When paying refinance costs may still make sense

Paying fees to refinance may still be reasonable if the new loan offers enough ongoing value. This could include a lower interest rate, a structure that better suits your cash flow, useful offset or redraw features, a more appropriate fixed or variable split, or the ability to simplify your finances.

For some borrowers, the benefit is not only the repayment saving. Refinancing may support a broader goal, such as restructuring after a change in income, accessing equity, or moving away from a loan that no longer fits. These outcomes depend on lender criteria and your individual financial position.

Final thoughts

The costs of refinancing a home loan in Australia can include discharge fees, fixed rate break costs, application fees, valuation fees, settlement costs, government registration fees, LMI and ongoing package fees. Some may be small, while others can materially affect whether switching is worthwhile.

A break-even calculation is a practical starting point: add up the upfront costs, estimate the monthly saving, then consider how long you expect to keep the new loan. From there, compare the total cost, loan features and risks before deciding whether to proceed.

Because refinancing outcomes depend on your circumstances, the property, lender criteria and the loan product, you may wish to consider seeking personalised guidance from a licensed mortgage broker, lender or financial professional before making a decision.
