Refinancing a home loan may look attractive when a new lender offers a lower interest rate, different features or a repayment structure that better suits your plans. But the interest rate is only one part of the decision. Refinancing costs in Australia may include discharge fees, settlement charges, application fees, valuation costs and, in some cases, break costs or lender's mortgage insurance.

Before you apply, it may be worth estimating whether the likely savings or benefits outweigh the cost to refinance a home loan. A simple break-even calculation can help you compare the upfront cost of switching with the ongoing difference in repayments. This article explains the main mortgage refinance fees to consider, how they vary, and how to work out a sensible break-even point. This article is general information only and does not take into account your personal situation, financial objectives or needs. 

Why refinancing costs matter

A refinance replaces your current home loan with a new loan, either with your existing lender or a different lender. The potential benefit may be a lower repayment, a different interest rate type, improved loan features, debt consolidation, access to equity or a more suitable loan structure.

However, a refinance is not automatically worthwhile just because the advertised interest rate is lower. Fees, charges and changes to the loan term may reduce or even outweigh the benefit. A loan that lowers your monthly repayment by extending the term, for example, may improve short-term cash flow but could increase total interest paid over the life of the loan.

If you are at the early research stage, the Mortgage Refinance Solutions homepage may help you frame the broader refinance assessment. This article focuses specifically on the cost side of that decision.

Common mortgage refinance fees in Australia

Fees vary between lenders, loan types and borrower circumstances. Some fees may be charged by your existing lender, some by the new lender, and some by third parties involved in settlement. Always ask for a written breakdown before you proceed.

Cost type What it generally relates to When to pay close attention
Discharge fee A fee your current lender may charge to close out and discharge your existing mortgage. When leaving your current lender, even if you are refinancing to a lower rate elsewhere.
Government registration or title fees Charges associated with registering or changing mortgage interests on the property title. When comparing total settlement costs, as these are separate from the advertised interest rate.
Settlement or electronic lodgement fees Costs associated with completing the refinance settlement and transferring security arrangements. When reviewing the final settlement statement and loan documentation.
Application or establishment fee A fee the new lender may charge to assess, approve or set up the new loan. When comparing lenders that advertise similar interest rates but different fee structures.
Valuation fee A charge for assessing the value of the property used as security. When the lender requires a full valuation or when your loan-to-value ratio may be close to a lender’s limit.
Legal, documentation or settlement administration fees Costs related to preparing, reviewing or processing loan and settlement documents. When a refinance involves more complex ownership, security or loan arrangements.
Fixed-rate break costs Costs that may apply if you exit a fixed-rate loan before the fixed term ends. When refinancing during a fixed-rate period, as break costs can be significant and vary over time.
Lenders mortgage insurance Insurance that protects the lender if the borrower defaults, usually linked to higher loan-to-value lending. When increasing borrowings, property value has changed, or your equity position is below a lender’s preferred threshold.
Package or annual fees Ongoing fees attached to some loan packages or bundled banking products. When a lower rate comes with annual costs that reduce the net benefit.
Broker or advice-related fees Some brokers may charge fees depending on their model, services and lender arrangements. When comparing assistance options. Ask how the broker is paid and whether any borrower-paid fee applies.

Costs from your current lender

Your current lender may charge a home loan discharge fee when you close your existing loan. If you have a fixed-rate home loan, you should also ask whether break costs apply. These costs can change depending on market rates, remaining fixed term, loan balance and lender methodology.

Do not assume a fixed-rate break cost will be small or that it can be known without asking your lender. If you are considering refinancing before the fixed term ends, request a current payout figure and ask how long that quote remains valid.

Costs from the new lender

The new lender may charge application, establishment, valuation, documentation, settlement or package fees. Some lenders waive or reduce certain fees as part of an offer, but the overall value depends on the full loan structure, not just one waived cost.

When comparing offers, ask whether the quoted repayment includes ongoing fees, whether the rate is introductory or variable, and what features are included. Offset accounts, redraw, split loans and package benefits can be useful for some borrowers, but they may also come with conditions or fees.

Third-party and settlement costs

Some refinance costs are not controlled entirely by the outgoing or incoming lender. These may include government title registration costs, settlement processing fees and other administrative charges. The exact treatment can depend on your state or territory, the property title, lender requirements and the settlement process.

These costs may appear small compared with the loan balance, but they still affect the break-even point. Include them in your calculation where they are known or reasonably estimated.

Lenders mortgage insurance and refinancing

Lenders mortgage insurance, often called LMI, can be a major cost consideration. It may apply if the lender considers the loan-to-value ratio too high under its credit policy. This can become relevant if property values have fallen, if you are borrowing more than your current balance, or if you have limited equity.

If you paid LMI on your original loan, that does not necessarily mean it transfers to a new lender. The new lender will assess the new application under its own criteria. Before refinancing, check whether LMI may apply and whether the potential benefit of refinancing still makes sense after that cost is included.

What is a refinance break-even point?

The refinance break-even point is the estimated time it takes for your ongoing savings to recover the upfront or switching costs. It is usually expressed in months.

A simple formula is:

Total refinance costs divided by monthly repayment savings equals the break-even period in months.

For example, if your total switching costs are estimated at a certain amount and your new loan reduces your monthly repayment, the break-even point is the number of months required for those monthly savings to equal the cost of refinancing. The shorter the period, the sooner the refinance may begin to provide a net cash-flow benefit. The longer the period, the more important it is to consider whether you expect to keep the loan long enough to benefit.

This is a simplified calculation. It does not capture every factor, such as changes in loan term, future rate movements, offset usage, tax considerations for investors or differences in loan features.

How to estimate your refinance break-even point

You can estimate the break-even point using a structured process:

  1. List exit costs from your current loan. Include discharge fees, fixed-rate break costs if relevant, and any other payout-related charges.
  2. List setup costs for the new loan. Include application, establishment, valuation, settlement, legal, package and government registration costs where applicable.
  3. Check whether LMI may apply. If it may apply, include it in your comparison before deciding whether the refinance is worthwhile.
  4. Compare like-for-like repayments. Try to compare the same loan balance and remaining term where possible, otherwise a lower repayment may simply reflect a longer repayment period.
  5. Calculate the monthly difference. Subtract the estimated new monthly repayment from your current repayment, allowing for ongoing fees where relevant.
  6. Divide total costs by the monthly saving. This gives an estimated number of months to break even.
  7. Compare the result with your plans. If you may sell, move, refinance again or change loan structure before the break-even point, the value of switching may be reduced.

A calculator can help you test repayment differences under different interest rates, loan terms and balances. You can use the site’s refinance calculator as a starting point, but remember that calculator outputs are estimates and depend on the assumptions you enter.

Look beyond the monthly repayment

Monthly repayment savings are useful, but they are not the only measure of value. A refinance may reduce the repayment by resetting the loan over a longer term. This can improve cash flow, but it may also increase the total interest paid if you take longer to repay the debt.

When comparing refinance options, you may wish to consider:

  • whether the loan term is staying the same or being extended;
  • the total estimated interest over the remaining life of the loan;
  • ongoing annual or package fees;
  • whether offset or redraw features could reduce interest if used effectively;
  • the flexibility to make extra repayments;
  • whether the interest rate is fixed, variable or split;
  • the risk that variable rates may change after settlement;
  • your expected plans for the property and loan over the next few years.

A refinance that looks attractive on monthly repayments may be less compelling once these factors are included. Conversely, a refinance with modest repayment savings may still be useful if it provides features or flexibility that are valuable to your circumstances.

How cashback offers and fee waivers affect the calculation

Some lenders may offer cashback, rebates or fee waivers to attract refinance customers. These may reduce the net cost of refinancing, but they should be assessed carefully.

Before including an incentive in your break-even calculation, check the conditions. Ask whether you need to borrow a minimum amount, hold the loan for a minimum period, settle by a particular date, or meet other lender criteria. Also compare the interest rate, fees and loan features after the incentive is taken into account.

A one-off incentive should not be the only reason to refinance. The ongoing loan structure still needs to suit your broader needs, eligibility and risk tolerance.

Some questions to consider asking before refinancing

Before signing a refinance application, consider asking your current lender, prospective lender or broker:

  • What is the total payout figure for my current loan?
  • Does a home loan discharge fee apply?
  • Are there any fixed-rate break costs, and how long is the quote valid?
  • What upfront fees will the new lender charge?
  • Will any government, settlement or registration costs apply?
  • Could lenders mortgage insurance apply to the new loan?
  • What ongoing annual, monthly or package fees apply?
  • Is the new repayment based on the same remaining loan term?
  • What happens to my offset account, redraw balance or linked banking products?
  • Are there conditions attached to any cashback, rebate or fee waiver?

When refinancing costs may outweigh the benefit

Refinancing may be less attractive if the total costs are high and the repayment difference is small. It may also be less suitable if you plan to sell the property soon, if a fixed-rate break cost is substantial, or if the new loan extends your term in a way that increases long-term interest more than expected.

There may also be non-cost reasons to pause. If your income, credit history, property value or employment situation has changed, your available options may differ from what was available when you first took out the loan. Lenders will assess applications under their current credit policies.

Final thoughts

Refinancing can be a useful way to review your home loan, but it should be assessed on more than the headline interest rate. The key is to compare total costs, ongoing repayments, loan features and the time needed to break even.

As a general rule, the decision becomes clearer when you know three things: what it costs to leave your current loan, what it costs to set up the new one, and how long the expected savings or benefits may take to recover those costs. Because lender fees, eligibility and pricing depend on individual circumstances and provider criteria, it is worth checking the details before making a commitment.
