Comparison Rate vs Interest Rate: What's the Difference?  banner

Before comparing car loans, it's easy to focus on the advertised interest rate. After all, a lower percentage sounds like a better deal.

However, the interest rate doesn't always tell the whole story.

Some loans with a low advertised rate may include fees that increase the overall cost of borrowing. That's why lenders also provide a comparison rate, which gives borrowers a clearer picture of what a loan may actually cost over time.

Understanding the difference between these two figures can help you compare loans more confidently and avoid unexpected costs.

What Is an Interest Rate?

An interest rate is the percentage a lender charges you for borrowing money.

It's one of the main factors that determines your repayments, but it's not the only cost associated with a loan.

Depending on the lender, you may be offered:

  • Fixed interest rates
  • Variable interest rates

Each has its own advantages depending on your financial goals. If you're still deciding between them, read our guide on Fixed vs Variable Interest Rates: Which Loan Option Is Right?

What Is a Comparison Rate?

A comparison rate is designed to help borrowers compare loans more fairly.

It combines:

  • The interest rate
  • Many standard loan fees and charges

This gives a better indication of the overall cost of the loan than the advertised interest rate alone. However, it's important to remember that comparison rates are calculated using a standard loan amount and loan term, so your actual costs may differ depending on your individual loan.

Why Is the Comparison Rate Important?

Imagine two loans:

Loan A

  • Interest rate: 6.19%
  • Comparison rate: 7.45%

Loan B

  • Interest rate: 6.49%
  • Comparison rate: 6.70%

Although Loan A advertises the lower interest rate, Loan B may actually cost less overall because it includes fewer fees.

That's why comparing both figures is important before making a decision.

"The lowest interest rate doesn't always mean the lowest-cost loan."

What Fees Can Affect the Comparison Rate?

Depending on the lender, fees may include:

  • Establishment fees
  • Monthly account fees
  • Ongoing administration fees
  • Some mandatory loan charges

Certain costs, such as government charges or optional products, may not always be included.

Always read the loan documentation carefully so you understand exactly what you're paying for.

Should You Only Compare Comparison Rates?

No. A comparison rate is helpful, but it shouldn't be your only consideration.

You should also compare:

  • Loan features
  • Repayment flexibility
  • Early repayment options
  • Balloon payment availability
  • Customer service
  • Loan suitability

For example, if you're considering paying off your loan ahead of schedule, our article Can You Pay Off a Car Loan Early? explains what to consider before choosing a lender.

What Else Affects the Cost of Your Loan?

Besides the comparison rate, the total amount you repay can also be influenced by:

  • Your loan amount
  • Loan term
  • Deposit
  • Credit profile
  • Vehicle type

Our guide on Car Loan Interest Rates Explained explores the factors that influence the interest rate you're offered.

Conclusion

Both interest rates and comparison rates are important when comparing car loans. While the interest rate tells you the cost of borrowing money, the comparison rate provides a broader view by including many of the fees associated with the loan.

Looking at both figures, along with the loan features and repayment flexibility, can help you make a more informed borrowing decision.

FAQs

Is the comparison rate more important than the interest rate?

Neither is more important. The interest rate shows the borrowing cost, while the comparison rate helps estimate the overall cost of the loan by including many standard fees.

Why is the comparison rate usually higher?

Because it includes the interest rate plus many standard fees and charges associated with the loan.

Does every lender display a comparison rate?

Australian lenders are generally required to display a comparison rate when advertising consumer loans, subject to regulatory requirements.

Can two loans have the same interest rate but different comparison rates?

Yes. Different fee structures can result in different comparison rates even when the advertised interest rate is the same.

Should I always choose the lowest comparison rate?

Not necessarily. You should also consider loan features, flexibility, repayment options and whether the loan suits your financial needs.
