Fixed vs Variable Rate: Which One Suits You Right Now?

It's one of the most common questions first home buyers and refinancers face: should I fix my rate, go variable, or do a bit of both? There's no universal right answer — but understanding how each option works makes the decision a lot clearer.

What Is a Fixed Rate Home Loan?

A fixed rate loan locks in your interest rate for a set period — typically one to five years. During that time, your repayments stay exactly the same regardless of what happens to interest rates in the broader market.

This predictability is the main appeal. You know precisely what's coming out of your account each month, which makes budgeting straightforward. If rates rise during your fixed period, you're protected. If they fall, however, you won't benefit — you're locked in at your agreed rate regardless.

Fixed rate loans also tend to come with some restrictions worth knowing about:

• Extra repayments are often capped — many fixed loans limit how much extra you can pay off each year (commonly $10,000–$20,000 annually)

• Redraw may not be available — accessing extra repayments you've made isn't always an option on a fixed loan

• Break costs can be significant — if you want to exit a fixed loan early (to sell, refinance, or restructure), lenders can charge a break cost that varies depending on how much rates have moved since you fixed

  
  

What Is a Variable Rate Home Loan?

A variable rate loan moves with the market. When the Reserve Bank of Australia (RBA) adjusts the official cash rate — or when lenders change their own rates independently — your repayments go up or down accordingly.

The trade-off for that uncertainty is flexibility. Variable loans typically allow unlimited extra repayments, full access to redraw, and often come with an offset account — a transaction account linked to your loan where any balance reduces the interest you're charged. These features can be genuinely powerful tools for paying down your mortgage faster.

Variable loans are also easier to exit. There are usually no break costs, which gives you the freedom to refinance or restructure if your circumstances change.

How a Split Loan Works

A split loan lets you have the best of both worlds — partially. You divide your loan into two portions: one fixed, one variable. For example, you might fix 60% of your loan for certainty on the bulk of your repayments, while keeping 40% variable to retain access to an offset account and the ability to make extra repayments.

It's a popular option for borrowers who want some rate protection without giving up all flexibility. The proportions are entirely up to you and can be tailored to your situation.

So Which One Is Right for You?

There's no single answer, but here are some questions worth thinking through:

Consider fixing if you:

• Want certainty over your repayments and are on a tight budget

• Are concerned about rates rising in the near term

• Don't plan to sell or refinance during the fixed period

• Don't need to make large extra repayments

  
  

Consider variable if you:

• Want the flexibility to make extra repayments or use an offset account

• May need to sell or restructure your loan in the next few years

• Are comfortable with some movement in your repayments

• Want to benefit if rates fall

  
  

Consider splitting if you:

• Want a middle ground between stability and flexibility

• Have an offset account you plan to use actively

• Are uncertain about where rates are heading

  
  

A Note on Timing

It can be tempting to try to "time" the market — fixing when you think rates are about to rise, going variable when you expect them to fall. The reality is that even professional economists regularly get rate forecasts wrong. Rather than trying to predict the future, it's usually more useful to focus on what suits your financial situation and goals right now.

What matters most is that your loan structure works for your life — not that you've made the perfect call on rate movements.

The Bottom Line

Fixed, variable, and split loans each have genuine merit depending on your circumstances. The right choice comes down to how much certainty you need, how much flexibility you want, and what you're planning to do with the property over the next few years.
