When Should You Refinance Your Home Loan in 2026?

🔄 What Refinancing Actually Means🔗

Refinancing means replacing your existing home loan with a new one, either with your current lender or a different one. The new loan pays out the old one, and you start fresh with new terms, a new rate, and potentially new features.

There are two flavours worth knowing. An internal refinance, or "loan variation," keeps you with the same lender but moves you to a different product. An external refinance means switching to a new lender entirely, usually more paperwork, but it tends to deliver bigger savings since you're forcing lenders to actually compete for your business.

📈 Why Australians Are Refinancing Right Now🔗

Over 640,000 Australian mortgages were refinanced in 2025, up roughly 20% on 2024, according to the Australian Banking Association. Forecasts project that figure climbing to 762,000+ in 2026, a further 19% increase.

The context matters here. The RBA cut the cash rate three times through 2025, taking it from 4.35% down to 3.60% by August 2025, then through early 2026 it reversed course, three consecutive hikes in February, March and May 2026 pushed the cash rate back up to 4.35%, where it has been held since. That rollercoaster has left many borrowers on rates that no longer reflect the best available deals.

🎯 The essential: Average variable rates currently sit between 6.24% and 6.92% p.a., depending on the lender and loan type. The lowest advertised rates are around 5.69% p.a. for owner-occupiers. The gap between what most people are paying and what's available is real, and that gap is what's driving the refinancing wave.

The average refinanced loan for owner-occupiers is $603,000. At that size, even a modest rate improvement translates to meaningful dollar savings every month. Add cost-of-living pressure and fierce competition between lenders, and you have a market where staying put is increasingly expensive.

💡 The Main Reasons to Refinance🔗

Chasing a lower interest rate. The most common reason, and the maths is straightforward. On a $600,000 loan, a 0.5% rate reduction saves roughly $3,000 a year in interest, or $250 a month. Even a 0.3% difference on that loan size adds up to around $1,800 annually. The key is comparing the comparison rate, not just the headline rate.

Accessing home equity. If your property has grown in value, you may have built up equity you can access by refinancing to a larger loan. Common uses include funding renovations, buying an investment property, or covering other major expenses, just be clear-eyed that borrowing against your home shifts risk onto your biggest asset.

Switching loan type. Some borrowers refinance to move from variable to fixed, or the other way around, depending on where they think rates are heading. Our guide to fixed vs variable vs split home loans walks through that trade-off in full. Others drop features they're not using, like an offset account with a higher rate attached, to get a leaner, cheaper loan.

Debt consolidation. Bundling personal loans or credit card debt into your home loan can cut the interest rate on that debt significantly, credit cards often charge 18 to 22% p.a., rolling that into a home loan at around 6% looks attractive on paper. The risk is extending short-term debt over a 25 to 30 year term, which can cost more in total interest even at a lower rate. Run the numbers carefully before doing this.

Escaping a high-fee package. Many lenders sell "professional packages," bundling a discounted rate with an annual fee, often $300 to $400 a year. If you're not using the bundled features (credit card, offset account, transaction account), that fee may outweigh the rate discount. Refinancing to a no-frills loan can save money even if the rate is similar.

💰 The Real Costs of Refinancing (Don't Underestimate These)🔗

Refinancing isn't free, and the fees are easy to underestimate until they show up as line items at settlement.

Government registration fees vary by state: roughly $175.70 in NSW, $238.14 in QLD, $125.70 in VIC, $216.60 in WA, $198 in SA, $178 in ACT, $163.30 in TAS and $176 in the NT. Confirm the current figure with your state's land titles office before budgeting.

⚖️ The Break-Even Calculation🔗

This is the most important number in any refinancing decision. The formula: total refinancing costs divided by monthly interest savings equals the number of months to break even.

Worked example: a $600,000 loan at 6.50% p.a., refinanced to a new loan at 5.90% p.a., a 0.60% difference. Monthly saving is $600,000 × 0.006 ÷ 12 = $300 a month. Total refinancing costs, at a mid-range estimate, come to $1,500. Break-even point is $1,500 ÷ $300 = 5 months.

Five months is a very short break-even, refinancing makes clear sense here if you're planning to hold the loan for at least a year. Flip the scenario: if costs are $2,000 and the monthly saving is only $80 (a 0.15% rate difference on the same loan), the break-even is 25 months. If you're planning to sell or refinance again before then, you're likely to lose money on the switch.

📝 How to Actually Refinance (Step by Step)🔗

1. Check your current loan's exit costs. Call your lender for a payout figure and written discharge fee, do this before applying anywhere else.
2. Compare rates properly using the comparison rate. The headline rate is a marketing number, the comparison rate is required by law to be displayed alongside it and includes most fees, a much better basis for comparison.
3. Check your LVR. Get a rough property valuation before applying. If your loan-to-value ratio has crept above 80%, you may face Lenders Mortgage Insurance with the new lender, which can wipe out your savings entirely.
4. Get your paperwork ready. Recent payslips, the last two years of tax returns, three to six months of bank statements, and your current loan statements. Having these ready speeds up the process significantly.
5. Decide: mortgage broker or go direct. A broker can access dozens of lenders and compare products, usually at no cost to you, since they're paid by the lender. Going direct can be faster if you already know who you want and have a straightforward application.
6. Apply and settle. Most lenders take two to six weeks to process. Your new lender handles the settlement with your old lender, so you don't need to manage the payout yourself.

⚠️ Common Mistakes to Avoid🔗

Refinancing too often. Every refinance resets the break-even clock. Switching every 12 to 18 months chasing cashback offers or marginally lower rates means fees eat your savings faster than the rate difference builds them. Run the break-even calculation every single time.

Ignoring LMI risk. Property values don't always go up. If your home has fallen in value, or you've borrowed more against it since buying, your LVR may have risen above 80%. Triggering LMI on a refinance can cost thousands and make the whole exercise pointless.

Chasing rate without checking features. A lower rate with no offset account isn't always better than a slightly higher rate with a functioning one. If you hold $50,000 in savings, an offset account on a $600,000 loan at 6.50% saves roughly $3,250 a year in interest. Dropping the offset to save 0.20% on the rate, worth $1,200 a year, would leave you $2,050 worse off.

Not reading the comparison rate. The headline rate is what lenders advertise, the comparison rate is what the loan actually costs once fees are included. A loan with a 5.69% headline rate and a 6.10% comparison rate has significant fees baked in, always compare comparison rates when shopping around.
