How do I decide between a fixed or variable interest loan?

Published by MFAA

Unsure about whether to lock down your interest rate for a period with a fixed rate home loan, or take your chances with a variable rate home loan? 

It’s a decision everyone faces – from first-home buyers right through to investors - at various points in a loan’s life. 

The choice can cause anxiety and confusion for some people because there’s no one-size-fits-all answer as to which option is better, and it can be hard to predict interest rate movements. Whether to go fixed or variable will depend on your unique circumstances. 

That’s one of the many reasons why many buyers turn to a mortgage broker. Brokers have tried-and-true methods designed to help you understand how different loan types and interest rate changes can impact your plans and priorities.

So how would a broker help you pick between fixed or variable?

The answer to this question may depend on your requirements and objectives which you should establish up front.

One of the first questions your broker may ask you, "What’s more important to you: the stability of knowing your repayments are going to stay the same? Or the flexibility to make unlimited repayments with no penalty?”. 

Your decision needs to work for you

Fixed rate loans provide confidence that rate changes won’t affect you – but that works both ways. You won’t pay more if rates rise but you won’t benefit if rates drop. Certainty may be your highest priority if you have a fixed budget.

If you want to have a loan that is fully flexible where you can make unlimited extra repayments with no penalty, a fixed rate may not be the most suitable option because you are usually limited with the extra repayments you can make. For example, there’s just a handful of lenders that have a 100% offset account linked to a fixed rate home loan.

Variable rate home loans come with less certainty – if interest rates go up or down your repayments can change – but generally more freedom to pay off your loan faster. Being open to the changes in interest rates often allows you to access loans with more flexible and attractive features like offset and redraw accounts.

Variable rate loans may make it easier if you’re thinking about selling your home soon, or want to switch loans if you find a better deal, because fixed-rate home loans often have penalty fees for those wanting to get out early. 

Best of both worlds?

Splitting your home loan usually gives you some of the benefits of both a fixed and a variable loan, which may make it an attractive third option to consider. There’s usually no limit on how you split your loan, provided that the relevant lender offers this option.

A split loan can give you peace of mind that a certain portion of your loan is not going to have any variation, as well as the variable component where you can make unlimited extra repayments.


As you can see, there are a lot of things to consider. It is always recommended you read any loan product’s fine-print carefully if making financial product decisions yourself, or find a reputable, accredited and trustworthy MFAA Accredited Finance Broker to help you navigate the experience.
