Fixed vs Variable Car Loan: Which Is Better in Australia?

A fixed car loan has an interest rate that stays the same for the entire loan term, making repayments predictable. A variable car loan has an interest rate that can rise or fall with market conditions, so your repayments may change over time. The best option depends on whether you value repayment certainty or the potential to benefit from lower interest rates.

What Is a Fixed Car Loan?

A fixed car loan locks in your interest rate when the loan begins. Your scheduled repayments usually remain the same until the loan is fully repaid.

Advantages

• Predictable repayments
• Easier household budgeting
• Protection if interest rates increase
• Greater repayment certainty

Things to Consider

• You won’t benefit if market interest rates fall.
• Some lenders may charge fees for paying off the loan early.
• Additional repayment options may be limited.

What Is a Variable Car Loan?

A variable car loan has an interest rate that can change during the loan term.

If rates decrease, your repayments may become lower. If rates increase, your repayments can rise.

Advantages

• Potential savings if interest rates fall
• Often more flexible repayment options
• Extra repayments may be allowed without penalty (depending on the lender)

Things to Consider

• Monthly repayments can change.
• Budgeting may be more difficult.
• Total interest paid is less predictable.

Which Loan Could Cost Less?

Neither loan type is always cheaper.

A fixed loan may save money if interest rates increase after you borrow.

A variable loan may cost less if interest rates decrease during your loan term.

The actual cost depends on:

• Interest rate
• Comparison rate
• Loan amount
• Loan term
• Fees and charges
• Extra repayments
• Balloon payment (if applicable)

Questions to Ask Before Choosing

• Can I comfortably afford higher repayments if interest rates increase?
• Do I value certainty more than flexibility?
• Will I make extra repayments?
• Is there an early repayment fee?
• What is the comparison rate?
• Does the loan include ongoing fees?

Common Mistakes

• Comparing only the advertised interest rate instead of the comparison rate.
• Choosing the lowest repayment without considering the total loan cost.
• Ignoring establishment or ongoing fees.
• Not checking whether extra repayments are allowed.
• Overlooking early payout conditions.
