Fixed vs Variable Rate Car Loans: Which One Is Right for You?

When you're taking out a car loan, one of the decisions you'll need to make is whether to go with a fixed or variable interest rate. For most personal car loans in Australia, fixed rates are by far the most common — but it's worth understanding why, and what the difference actually means for you.

Fixed Rate Car Loans

With a fixed rate loan, your interest rate is locked in for the entire term of the loan. That means your repayment amount stays exactly the same from month one to the final month — regardless of what happens to interest rates in the broader economy.

Advantages of Fixed Rates

Predictability is the big one. You know exactly what you'll pay each month, which makes budgeting easy. You're also protected if rates rise — your rate doesn't change. This peace of mind is why most car loan borrowers in Australia choose fixed rates.

Disadvantages of Fixed Rates

If interest rates fall significantly, you won't benefit — you're locked into your original rate. Also, fixed rate loans often have break costs or early repayment fees if you want to pay the loan off ahead of schedule.

Variable Rate Car Loans

A variable rate loan has an interest rate that can change over the term of the loan, usually in line with movements in the broader interest rate environment. Variable rate car loans are less common in Australia than variable rate home loans.

Advantages of Variable Rates

If rates drop, your repayments could decrease. Variable rate loans are also often more flexible, allowing additional repayments or early payoff without significant penalties.

Disadvantages of Variable Rates

Your repayments can increase if rates rise, which makes budgeting less predictable. For a car loan — which is typically a five to seven year commitment — a lot can change in the interest rate environment.

What Do Most People Choose?

In my experience, the vast majority of personal car loan borrowers in Australia choose a fixed rate, primarily for the certainty and simplicity. For business finance (chattel mortgage, finance lease), fixed rates are almost universal.

What's the Right Choice for You?

For most people, a fixed rate car loan is the right choice because of the predictability and simplicity. If you're someone who values flexibility and might want to make extra repayments or pay off the loan early, a variable rate might be worth exploring. When you work with me, I'll help you compare both options and make the choice that suits your situation. Reach out and let's talk it through.
