Understanding Loan Comparison Rates in Australia
The comparison rate tells you the true cost of a loan — not just the interest rate. Here's what it means and why it matters when you're comparing options.
When you're comparing car loans or personal loans, you'll always see two numbers side by side: the interest rate and the comparison rate. Most people focus on the interest rate and overlook the comparison rate — which is actually the more useful number.
Let me explain what it means and how to use it.
What Is the Comparison Rate?
The comparison rate is a standardised figure that combines the interest rate with most of the fees and charges associated with the loan, expressed as a single annual percentage. The idea is to give you a single number that better represents the true cost of the loan, making it easier to compare different products side by side.
Under Australian credit law, lenders are required to display the comparison rate alongside their advertised interest rate for most consumer loans.
Why the Advertised Rate Can Be Misleading
A lender can advertise a low interest rate but charge high establishment fees, monthly account-keeping fees, or other charges that significantly increase the cost of the loan. The comparison rate captures these costs, giving you a better picture of what you'll actually pay.
For example, a loan advertised at 6.99% with high fees might have a comparison rate of 8.5%. Another loan at 7.5% with minimal fees might have a comparison rate of 7.6%. The second loan is actually cheaper despite the higher headline rate.
What Isn't Included in the Comparison Rate?
There are some costs that aren't captured by the comparison rate, including: government fees (like stamp duty), fees that are conditional on future events (like early repayment fees), redraw fees, and optional features. So the comparison rate is a useful guide, but not a perfect one.
The Standard Benchmark
In Australia, comparison rates for personal and car loans are calculated on a standard $30,000 loan over five years. This standardisation means you can legitimately compare two different loans against each other, as long as your loan amount and term are similar.
How I Use Comparison Rates for Clients
When I compare loans for clients, I always look at the comparison rate as a starting point — but I also look at the full fee schedule because some costs (like early repayment fees) that aren't in the comparison rate can be very relevant if you plan to pay the loan off early.
