If you are asking yourself should I refinance my home loan, the short answer is: refinancing is worth considering when the savings from a lower interest rate outweigh the costs of switching, or when you want to unlock equity built up in your property. Whether that applies to your situation depends on your current rate, loan balance, remaining term, and financial goals. This guide walks you through every angle so you can make a confident, well-informed decision.

When Does Refinancing Actually Save You Money?

Refinancing saves real money when the gap between your current interest rate and the new rate is large enough to recover the switching costs within a reasonable timeframe. According to RBA data from early 2026, the average outstanding variable mortgage rate for owner-occupiers sits around 6.3% per annum, while competitive new-customer rates from lenders are being advertised as low as 5.6% to 5.9%. On a $600,000 loan balance with 20 years remaining, a reduction of just 0.5% per annum translates to roughly $3,000 in annual interest savings or around $60,000 over the life of the loan.

The widely used “break-even rule” suggests refinancing makes sense if you can recover all costs within 18 to 24 months. To calculate your own break-even point, divide total refinancing costs by your monthly savings. If the result is under two years and you plan to stay in the property, refinancing is almost always worth pursuing.

Key Situations Where Refinancing Delivers the Most Value

• Your current fixed rate is expiring and rolling onto a higher revert rate
• You have built up strong equity (typically 20% or more) and can now avoid Lenders Mortgage Insurance
• Your credit profile or income has improved since you first took out the loan
• You want to consolidate higher-interest debt such as personal loans or credit cards into one manageable repayment
• You are looking to switch from interest-only to principal-and-interest repayments to build equity faster

For a deeper look at how different loan structures affect your long-term costs, our home loan guide for Australia in 2026 covers the full spectrum of loan types, rate structures, and how to compare them side by side.

What Are the Real Costs of Refinancing a Home Loan?

One of the most overlooked aspects of refinancing is the full cost picture. Many borrowers focus only on the new interest rate and forget to account for the fees that come with switching lenders. According to ASIC’s MoneySmart figures, the total cost of refinancing in Australia typically ranges from $1,000 to $3,500, depending on your lender, state, and loan size.

Common Fees to Budget For

• Discharge fee: Charged by your existing lender to close out your current loan, usually between $150 and $400
• Break cost (fixed loans only): If you are leaving a fixed-rate loan early, break costs can be significant, sometimes running into thousands of dollars depending on how far rates have moved
• Application or establishment fee: Some new lenders charge $300 to $700 to set up your new loan
• Valuation fee: The new lender will usually require a property valuation, costing $200 to $600
• Title registration and legal fees: Mortgage registration fees vary by state; in Victoria, for example, CoreLogic data notes these can add $100 to $200 to the total
• Lenders Mortgage Insurance (LMI): If your equity is below 20% of the new lender’s valuation, you may need to pay LMI again, which can run into thousands

Always request a Key Facts Sheet from any lender you are considering. Under Australian law, lenders are required to provide this document, which outlines all fees and the comparison rate, making it easier to do an apples-to-apples comparison.

How Can I Use Refinancing to Release Home Equity?

Equity release is one of the most powerful and least understood reasons to refinance. According to CoreLogic’s 2025 Pain and Gain Report, the median Australian homeowner who purchased a decade ago has seen property values rise by more than 70% in most capital cities. That growth translates into significant usable equity sitting inside your home.

When you refinance to a higher loan amount than your current balance, you effectively “cash out” a portion of that equity. This strategy is commonly used for:

• Renovation and improvements: Adding a bedroom, updating a kitchen, or building a granny flat to increase rental yield or resale value
• Investment property deposit: Using equity from your principal residence as a deposit on an investment property without touching savings
• Debt consolidation: Replacing multiple high-rate debts with a single low-rate mortgage repayment
• Education and major life expenses: Funding university fees or other significant costs at mortgage rates rather than personal loan rates

It is important to understand that accessing equity increases your loan balance and your total interest bill over time. A financial adviser or mortgage broker can help you model the long-term impact before you commit. To understand all the options available, our guide to home equity loans and equity release explains how to unlock your property’s value responsibly and what each product structure means for your repayments.

What Should I Check Before I Refinance?

Before you submit a single application, there are several practical checks that will improve your chances of approval and help you get the best possible outcome.

1. Know Your Current Loan Details

Pull out your most recent mortgage statement and note the exact balance, remaining term, current interest rate, and any fixed-rate expiry dates. According to the Australian Banking Association, borrowers who prepare this information in advance reduce the time to approval by an average of five business days.

2. Check Your Credit Score

Your credit score directly influences the rate lenders will offer you. A score above 700 is generally considered good; above 800 is excellent. You can access your credit report free of charge from agencies such as Equifax, Experian, or illion. If your score has dipped due to missed payments, spending three to six months repairing it before applying can unlock meaningfully better rates.

3. Calculate Your Loan-to-Value Ratio (LVR)

Lenders use your LVR (loan balance divided by property value) to determine your risk profile. An LVR below 80% means you avoid LMI and typically access the most competitive rate tiers. CoreLogic’s February 2026 figures show that median Melbourne house values sit around $920,000, meaning many homeowners who purchased five or more years ago now have LVRs well under that threshold.

4. Compare More Than Just the Interest Rate

The comparison rate is a more useful benchmark because it rolls in most standard fees. Be sure to also assess offset account features, redraw facilities, and repayment flexibility. If your goal is to clear your mortgage sooner, these features can be just as valuable as a lower headline rate. Our resource on paying off your home loan faster outlines practical strategies that work best when combined with the right loan structure.

5. Get at Least Three Quotes

Whether you approach lenders directly or use a mortgage broker, comparing at least three offers gives you genuine negotiating power. Lenders know you are shopping around, and many will sharpen their rates to win your business. The RBA’s 2025 Household Financial Conditions report found that borrowers who switched lenders reduced their interest rate by an average of 0.4 to 0.6 percentage points compared with those who simply asked their existing lender for a discount.

Are There Situations Where Refinancing Is Not the Right Move?

Refinancing is not always the best strategy. There are circumstances where the costs or risks outweigh the benefits.

• You are close to paying off your loan: If you have fewer than five years remaining, the interest savings are modest and the switching costs may not be recoverable in time
• You face high fixed-rate break costs: If your lender’s break cost exceeds 12 months of potential savings, it is generally better to wait until the fixed term expires
• Your financial position has weakened: A recent job change, reduced income, or increased debt levels could mean you receive a less competitive offer or struggle to meet serviceability assessments
• Property values have fallen: If your property has dropped in value since purchase, your LVR may have risen above 80%, triggering LMI costs that undermine the savings

In these cases, it is worth speaking directly with your current lender first. Many lenders will offer a retention rate reduction to keep your business, which achieves a similar outcome without the paperwork or fees of a full refinance.

Deciding whether to refinance comes down to three core questions: how much will you save, what will it cost to switch, and does the outcome align with your broader financial plan. For most Australian homeowners with rates above the current market average, a structured review of their mortgage at least every two to three years is a sound financial habit. Take the time to run your numbers carefully, seek independent advice if you need it, and choose a loan structure that works not just for today but for where you want to be in five to ten years.
