When it comes to financing a vehicle, one of the most important decisions you’ll make is choosing between a fixed or variable interest rate for your car loan. Each option comes with its own advantages and potential drawbacks, and understanding how they work can help you make an informed choice that aligns with your financial goals. 

We’ll break down the differences between fixed and variable car loan rates and help you decide which is better suited to your needs.

What is a Fixed Interest Rate?

A fixed interest rate is set at the beginning of your loan term and remains unchanged throughout the life of the loan. This means that your repayments will stay the same for the entire duration of the loan, providing a sense of stability and predictability. Many borrowers prefer fixed-rate loans because they offer peace of mind—you’ll know exactly how much you need to repay each month, which can make budgeting easier.

Advantages of Fixed Interest Rates:

  • Predictable Repayments: With a fixed interest rate, you’ll never have to worry about your loan repayments increasing due to fluctuations in the market. This can make it easier to plan your budget, as your monthly repayment amount remains consistent.

  • Protection Against Rate Increases: If the market interest rates rise during your loan term, your rate won’t be affected. This can save you money in the long run, especially during periods of rising interest rates.

  • Financial Stability: For borrowers who prioritise financial stability and don’t want to be affected by market conditions, fixed-rate loans offer a reliable, stable option.

Disadvantages of Fixed Interest Rates:

  • Higher Initial Rates: Fixed rates tend to be slightly higher than variable rates at the start of the loan. This is because you’re paying for the stability of knowing your rate won’t increase.

  • Less Flexibility: If market rates decrease, you won’t benefit from the lower rates. You’re locked into the rate you agreed to at the beginning of the loan, even if more favourable rates become available.

  • Early Repayment Penalties: Fixed-rate loans often come with penalties for paying off the loan early, which may limit your flexibility if your financial situation changes.

What is a Variable Interest Rate?

A variable interest rate, on the other hand, fluctuates over time based on market conditions. Your monthly repayments may increase or decrease depending on changes to the RBA’s cash rate or other economic factors. While variable rates may initially be lower than fixed rates, they carry the risk of rising over time.

Advantages of Variable Interest Rates:

  • Potential for Lower Rates: At the start of the loan, variable rates are often lower than fixed rates, meaning your initial repayments could be cheaper. If market rates fall during your loan term, you’ll benefit from lower repayments.

  • More Flexibility: Many variable-rate loans offer more flexible terms, including the option to make additional repayments without penalty. This can help you pay off your loan faster and save on interest over time.

  • Opportunity to Take Advantage of Market Drops: If the market interest rates decrease, your rate may go down as well, leading to reduced monthly repayments and savings over the life of the loan.

Disadvantages of Variable Interest Rates:

  • Unpredictable Repayments: The biggest downside to a variable rate loan is that your repayments can fluctuate. If interest rates rise, your repayments will increase, which can put strain on your budget.

  • Exposure to Rate Hikes: In times of rising interest rates, a variable-rate loan can become significantly more expensive, making it difficult to predict your financial commitments.

  • Uncertainty: Variable rates can be unpredictable, which can cause stress for borrowers who prefer consistency and stability in their loan repayments.

Fixed vs Variable Car Loan Rates: Which is Better for You?

The answer to this question depends largely on your financial situation, risk tolerance, and long-term plans. Here are some factors to consider when deciding between a fixed or variable car loan rate:

1. Risk Tolerance

If you’re risk-averse and prefer the certainty of knowing your repayments will remain the same throughout the loan term, a fixed interest rate may be the better choice for you. On the other hand, if you’re comfortable with the possibility of fluctuating repayments and are confident that you can handle potential rate increases, a variable rate might be more appealing.

2. Current Market Conditions

In a low-interest-rate environment, variable-rate loans may offer an advantage, as you can benefit from potential rate decreases. However, if rates are expected to rise, locking in a fixed rate could protect you from future increases.

3. Financial Flexibility

If your budget allows for flexibility and you have the ability to make extra repayments, a variable-rate loan could be a smart choice. The opportunity to pay off the loan faster and save on interest can make variable loans more appealing. However, if you need a predictable payment schedule to ensure your repayments align with your budget, a fixed rate will provide more stability.

4. Long-Term Plans

Consider your long-term financial goals. If you’re planning to pay off the loan early or have the flexibility to adjust your payments, a variable rate could give you the freedom to make additional repayments without penalties. But if your main concern is maintaining consistent repayments for the long haul, a fixed rate might be the way to go.

Combining Fixed and Variable Rates

Some lenders offer a split loan option, where part of your loan is subject to a fixed interest rate, while the other part has a variable rate. This can provide a balance between stability and flexibility, allowing you to benefit from the advantages of both types of loans.

Choosing Between Fixed and Variable Rates

If you value certainty and stability, a fixed rate might be the right choice for you. However, if you’re willing to take on some risk in exchange for potential savings, a variable rate could be more appealing.
