When considering a home loan, understanding both the interest rate and the comparison rate is crucial. These rates give you a full picture of your loan’s true cost, helping you make a well-informed decision.
What is a Comparison Rate?
A comparison rate is a percentage that lenders must display alongside the advertised interest rate on home loans. It includes most of the loan-related charges, giving you a clearer idea of its actual cost.
The interest rate represents the percentage of interest you pay on your loan. However, the comparison rate goes beyond that. It adds other fees, like establishment and account-keeping charges, to show the true cost of the loan.
Lenders must include both the comparison and interest rates in advertisements. The comparison rate accounts for mandatory fees, such as account-keeping and annual fees. But it does not include government fees (e.g., stamp duty or mortgage registration fees) or optional charges like redraw or offset fees.
How Do Comparison Rates and Interest Rates Differ?
Loans with low-interest rates might have high comparison rates if they include high fees. On the other hand, two lenders with the same interest rate may have different comparison rates due to varying fees.

How to Calculate a Comparison Rate
Calculating a comparison rate on your own can be tricky. To simplify the process, use a comparison rate calculator. You’ll need details like:
-
Loan amount
-
Loan term
-
Repayment frequency
-
Interest rate
-
Additional fees
The calculator will provide a more accurate representation of the actual cost of your home loan.
Why Use a Comparison Rate?
A comparison rate is valuable when comparing mortgage products. It can uncover hidden costs that interest rates alone may not reveal.
While comparison rates should generally be similar among major lenders, always use a comparison rate calculator for a detailed comparison of loans. Make sure to adjust the calculator to reflect your loan amount and term.
Final Thoughts
The comparison rate helps bring transparency to the overall cost of your mortgage. If you have questions about the components of your loan’s comparison rate, don’t hesitate to ask your lender for clarification.
