Refinancing your home loan means switching from your current mortgage to a new one, either with your existing lender or a different one. For many Australian homeowners, refinancing can unlock thousands of dollars in savings each year through lower interest rates, better loan features, or more suitable repayment structures. However, refinancing is not always the right move, and the decision requires careful consideration of your current loan terms, the costs involved, and your financial goals.

This guide walks you through the key scenarios when refinancing makes financial sense, how to calculate whether the savings outweigh the costs, and the practical steps to take when switching lenders or restructuring your home loan.

Step 1: Identify Your Primary Reason for Refinancing

The first step is to clarify why you are considering a refinance. According to ASIC MoneySmart, the most common reasons Australian borrowers refinance include securing a lower interest rate, accessing better loan features, consolidating debt, or accessing equity in their property (MoneySmart, 2026).

Lower interest rate: If your current variable or fixed rate is significantly higher than what is available on the market, refinancing to a lower rate can reduce your monthly repayments and the total interest paid over the life of the loan. Even a difference of 0.25 per cent can translate to meaningful savings on a large loan balance.

Better loan features: You may want an offset account to reduce interest charges, a redraw facility for flexible access to extra repayments, or the ability to make additional repayments without penalty. Some lenders also offer cashback incentives or fee waivers that make switching attractive.

Debt consolidation: Refinancing can allow you to roll higher-interest debts, such as credit cards or personal loans, into your home loan at a lower interest rate. This can simplify repayments and reduce your overall interest burden, though it does mean securing unsecured debt against your property.

Accessing equity: If your property has increased in value since you took out your original loan, refinancing can let you access that equity for renovations, investment, or other purposes, provided your loan-to-value ratio (LVR) remains within acceptable limits and you meet serviceability requirements.

Clarifying your primary goal helps you compare loan products more effectively and ensures you do not refinance solely for a minor benefit that does not justify the costs.

Step 2: Calculate the Total Cost of Refinancing

Refinancing is not free. Before you commit, you need to calculate the upfront and ongoing costs to determine if the potential savings justify the expense. Key costs include:

Break costs (fixed-rate loans): If you are on a fixed-rate home loan and you refinance before the fixed period ends, your lender may charge break costs to compensate for the lost interest revenue. These costs can range from a few hundred dollars to tens of thousands, depending on the remaining fixed term, the size of your loan, and how much interest rates have moved since you fixed your rate. Break costs are often the single largest barrier to refinancing a fixed loan, so request a break cost estimate from your lender before proceeding.

Application and settlement fees: New lenders typically charge application fees (often A$300 to A$600) and settlement or establishment fees. Some lenders waive these fees as part of promotional offers, so it pays to ask.

Valuation fees: The new lender will require a property valuation to confirm the current market value of your home, which can cost A$200 to A$400. Some lenders cover this cost, particularly if you are borrowing a large amount or have a strong credit profile.

Discharge fees: Your existing lender will charge a discharge fee (typically A$150 to A$350) to release the mortgage over your property.

Conveyancing or legal fees: You may need a solicitor or conveyancer to handle the transfer of mortgage documents, which can cost A$500 to A$1,000 or more.

Lenders mortgage insurance (LMI): If your new loan has an LVR above 80 per cent, you may need to pay LMI again, even if you paid it on your original loan. This can add thousands of dollars to the cost of refinancing.

Add these costs together to arrive at your total refinancing expense. Then compare this figure to your projected savings over a reasonable timeframe, such as two to three years, to determine if refinancing makes financial sense.

Step 3: Compare Interest Rates Using the Comparison Rate

Interest rates are the most visible factor in refinancing decisions, but the advertised rate alone does not tell the full story. In Australia, lenders are required to publish a comparison rate alongside the advertised interest rate. The comparison rate includes most fees and charges over the life of a A$150,000 loan with a 25-year term, giving you a clearer picture of the true cost of the loan.

When evaluating refinancing offers, always compare the comparison rates, not just the headline rates. A loan with a low advertised rate but high ongoing fees may cost more over time than a loan with a slightly higher rate and lower fees. Rates quoted here are illustrative only; as of June 2026, rates change frequently, so verify current terms with a licensed lender or broker before making a decision.

If you are moving from a variable rate to a fixed rate, or vice versa, consider your risk tolerance and expectations for future rate movements. Fixed rates provide certainty but lack the flexibility of variable loans, which allow unlimited extra repayments and often come with offset accounts.

Step 4: Assess the Breakeven Timeline

The breakeven point is the time it takes for your interest savings to exceed the upfront cost of refinancing. Calculating this figure helps you decide whether refinancing is worthwhile, particularly if you plan to sell your property or pay off your loan in the near future.

For example, if refinancing costs you A$3,000 in total and saves you A$150 per month in interest, your breakeven point is 20 months (A$3,000 divided by A$150). If you plan to stay in your home and keep the loan for longer than 20 months, refinancing makes sense. If you intend to sell or pay off the loan sooner, the savings may not justify the expense.

Be realistic about your timeline. Life circumstances change, and a refinance that looks attractive over five years may not deliver value if you move or restructure your finances within two years.

Step 5: Evaluate Loan Features and Flexibility

Interest rates are important, but loan features can have a significant impact on your financial flexibility and long-term savings. When comparing refinancing options, consider:

Offset accounts: An offset account is a transaction account linked to your home loan. The balance in the offset account reduces the principal on which interest is calculated, lowering your interest charges without requiring you to make extra repayments into the loan itself. Offset accounts are particularly valuable for borrowers with variable incomes or those who want to retain access to their savings while minimising interest.

Redraw facilities: A redraw facility allows you to access extra repayments you have made on your loan. This provides flexibility if you need funds for emergencies or opportunities, though some lenders charge fees for redraw transactions or limit the number of redraws you can make.

Repayment flexibility: Check whether the new loan allows unlimited additional repayments without penalty. Some loans, particularly fixed-rate loans, cap the amount you can repay above the minimum each year, which can limit your ability to pay off your loan faster.

Portability: If you plan to move house in the future, a portable loan allows you to transfer your existing mortgage to a new property without refinancing again, saving you application and settlement costs.

Weigh these features against the interest rate to determine which loan offers the best overall value for your circumstances.

Step 6: Check Your Serviceability and Credit File

Before you apply for a refinance, confirm that you meet the new lender’s serviceability requirements. Lenders assess your ability to repay the loan based on your income, expenses, existing debts, and financial commitments. If your financial situation has changed since you took out your original loan, for example, if your income has decreased, you have taken on new debts, or interest rates have risen significantly, you may not qualify for the refinance.

Check your credit file with one of the major credit reporting agencies to ensure there are no errors or adverse listings that could affect your application. A strong credit history improves your chances of approval and may help you negotiate better terms.

Step 7: Consider the Impact of Your Current Loan Type

The type of loan you currently hold affects the refinancing decision. If you are on a variable-rate loan, you generally face fewer barriers to refinancing, as variable loans do not typically carry break costs. However, if you are on a fixed-rate loan, break costs can be substantial, particularly if interest rates have fallen since you fixed your rate.

If you are in the final year of a fixed-rate term and break costs are relatively low, or if you are already on a variable rate, refinancing may be straightforward. If you are several years into a fixed term and break costs are high, refinancing may only make sense if the interest rate difference is large enough to offset those costs within your breakeven timeline.

Split loans, which combine a fixed and variable portion, offer a middle ground. You can refinance the variable portion without incurring break costs, while keeping the fixed portion in place if the break costs are prohibitive.

Common Mistakes to Avoid

Refinancing too frequently: Refinancing every time rates drop by a small margin can result in cumulative costs that erode your savings. Only refinance when the savings clearly justify the expense over a realistic timeframe.

Ignoring break costs: Borrowers on fixed-rate loans sometimes underestimate break costs and proceed with a refinance that ends up costing more than it saves. Always request a break cost estimate before committing.

Focusing only on the interest rate: A low advertised rate may come with high fees, limited features, or restrictive terms. Evaluate the comparison rate, loan features, and overall value, not just the headline rate.

Extending the loan term unnecessarily: Refinancing to a new 30-year term when you have already paid down 10 years of your original loan may lower your monthly repayments, but it increases the total interest paid over the life of the loan. If your goal is to pay off your loan faster, keep the term as short as you can comfortably manage.

Not shopping around: Do not accept the first refinancing offer you receive. Compare offers from multiple lenders, consider working with a mortgage broker who can access a wide range of products, and negotiate for better terms or fee waivers.

Frequently Asked Questions

How much can I save by refinancing my home loan?

Savings depend on the interest rate difference, your loan balance, and the remaining loan term. A reduction of 0.50 per cent on a A$400,000 loan could save around A$2,000 per year in interest, but you need to subtract refinancing costs to determine your net savings. Use an online refinancing calculator or speak with a licensed mortgage broker to estimate your specific savings.

Can I refinance if my property value has decreased?

Yes, but it may be more difficult. If your property value has fallen and your LVR is now above 80 per cent, you may need to pay lenders mortgage insurance again, and some lenders may decline your application. If your LVR exceeds 90 per cent, refinancing options are limited.

How long does the refinancing process take?

Refinancing typically takes between four and eight weeks from application to settlement, depending on the lender’s processing times, the complexity of your application, and how quickly you provide required documentation.

Do I need a mortgage broker to refinance?

No, but a broker can save you time by comparing multiple lenders, negotiating on your behalf, and guiding you through the application process. Brokers are typically paid by the lender, so their service is often free to you, though you should confirm this upfront.

What happens if I am rejected for a refinance?

If your application is declined, the lender will provide a reason, such as insufficient income, high existing debts, or adverse credit history. You can address the issue, for example, by paying down debts, correcting errors on your credit file, or improving your savings buffer, and reapply later. Alternatively, consider applying with a different lender that has less stringent serviceability criteria.

Conclusion

Refinancing your mortgage can be a powerful way to reduce interest costs, access better loan features, or restructure your debt, but it is not the right move in every situation. The decision hinges on the size of your potential savings, the costs involved, your current loan terms, and your financial goals.

Start by calculating the total cost of refinancing, including break costs if you are on a fixed rate, and compare this to your projected savings over a realistic timeframe. Evaluate loan offers using the comparison rate, not just the advertised rate, and weigh features such as offset accounts, redraw facilities, and repayment flexibility against the interest rate alone.

If the numbers stack up and the new loan aligns with your financial goals, refinancing can save you thousands of dollars over the life of your loan. If the breakeven timeline is too long, the costs are too high, or your circumstances do not support a change, staying with your current loan may be the smarter choice.

Before proceeding, confirm current rates and terms with a licensed lender or mortgage broker, and consider seeking personal advice to ensure the decision suits your individual circumstances.
