Fixed vs Variable Mortgage: Which Is Better? (2026)

If you’ve been following the mortgage rate rollercoaster, you know rates have been brutal—hovering above 6.5% for too long. But here’s the good news: experts are predicting a shift, with rates expected to start falling through 2026. This shift makes choosing between a fixed and variable rate more complex than ever. Basically, you are choosing between payment certainty (Fixed) or flexibility and potential savings (Variable). We're not telling you what to do, but we are laying out the facts so you can decide based on your financial comfort zone. Understanding the difference now means avoiding costly mistakes when your loan term ends.

Remember, fixed rates lock your interest rate in for a set period (usually 1 to 5 years), providing peace of mind. Variable rates change with the market, offering immediate access to rate drops but also exposing you to sudden rises. Before diving deep, it helps to understand how much you can afford to repay each month. Use our mortgage repayment calculator to get a baseline figure.

A fixed rate is like setting your mortgage payment in stone for a set term—say, 3 years. If the bank offers you a fixed rate of 6.0% for the next three years, that rate is guaranteed, no matter how much the Reserve Bank of Australia changes the official cash rate. This is perfect if your budget requires absolute payment certainty, such as if you know you'll be using the money for renovations next year and need predictable cash flow for the next three years.

The catch? When your fixed term ends, you face the 're-fix' decision. If you need to leave early, or 'break' the loan, you might face hefty exit fees or penalties. Also, if rates fall significantly, you are locked into paying the higher, fixed rate until your term expires. While they offer security, they sacrifice the ability to benefit immediately from market rate drops.

Variable rates are the market's heartbeat. With a variable rate, your repayments adjust immediately when the bank adjusts its lending rate. If the RBA cuts rates, your repayments drop instantly—a huge win! This is why many savvy homeowners favour variable loans, especially if they have an offset account. The offset account is your secret weapon; it links to your loan and effectively reduces the amount of money you are charged interest on, making rate drops feel even bigger.

The downside is the risk. If rates rise quickly—say, jumping from 6.0% to 7.0% in a year—your repayments rise with it. However, the flexibility means you can make extra repayments anytime, helping you pay down the principal faster and saving thousands in interest over time. Variable loans are ideal if you are disciplined and confident in your ability to manage fluctuating cash flow.

There is no one-size-fits-all answer. To make the best call in 2026, ask yourself two questions: 1) How certain is my income stream? and 2) Do I have a high-interest savings/offset account? If your income is variable (e.g., you're a freelancer) and you prioritize peace of mind, a fixed rate might be best. However, if you have stable income, are disciplined enough to save extra, and maintain an offset account, a variable rate is likely to save you more money in the long run.

Another option is the split loan. You can fix a portion (say, 50% of your loan) for stability and keep the other 50% variable for flexibility. This hybrid approach mitigates the risk of being completely exposed to market swings while still allowing you to capture potential rate drops.

Q: Do I always have to stick with the same bank?

A: Not necessarily. When your fixed term ends, you are free to shop around. Mortgage comparison services can help you find better rates elsewhere, even if you've been with the same bank for years.

Q: If I take a fixed rate, can I still make extra repayments?

A: Yes, but check your specific contract. Some fixed loans have clauses that restrict extra repayments, or they may charge a fee if you exceed the agreed schedule. Always read the fine print!

Q: Is it better to pay off the loan faster or to use an offset account?

A: Both are excellent strategies. Paying faster reduces the overall interest paid, while an offset account provides a flexible, interest-free buffer, making you highly resilient to rate increases.
