Comparison Rate Explained: What It Means for Your Home Loan
Comparison rate explained: see how it combines the interest rate with most fees into one figure, how it differs from the interest rate, and how to compare.
A comparison rate is a single figure that shows the true cost of a home loan by combining the interest rate with most of the fees. The interest rate explained on its own only tells part of the story, so the comparison rate exists to give you one number you can line up side by side across lenders. If you have ever wondered what a comparison rate is and why it sits next to the advertised rate, this guide walks through what it includes, how it differs from the interest rate, and how to use it when you compare home loans.
This is general information only. What suits you will depend on your circumstances and each lender’s criteria.
If you are starting your buying journey, the deposit, scheme and lender decisions come together on our first home buyers hub.
What is a comparison rate?
According to the Australian Securities and Investments Commission’s MoneySmart service, a comparison rate is “a single figure of the cost of the loan” that includes the interest rate and most fees. In plain terms, it bundles the headline interest rate together with the recurring and upfront costs of running the loan, then expresses the whole lot as one percentage.
The point is to stop a low advertised rate from hiding a loan that is expensive once the fees are added in. Two loans can advertise the same interest rate, yet one may carry higher fees. The comparison rate is designed to surface that gap so you are comparing like with like.
Interest rate vs comparison rate: why the difference matters
This is the question most first home buyers ask, so here is the short answer. The interest rate is the rate a lender advertises. The comparison rate takes that interest rate and adds most of the fees to produce a single figure you can use to compare loans.
The comparison rate is almost always higher than the interest rate, because it is carrying those extra costs. A larger gap between the two numbers can be a signal that the loan’s fees are on the heavier side. A smaller gap can suggest a leaner fee structure. It is a quick way to read the cost beyond the headline.
Two costs commonly fold into a comparison rate:
- An application fee, which MoneySmart describes as a one-off payment when you start a loan, also called an establishment, up-front or set-up fee.
- Ongoing fees, which MoneySmart describes as fees charged every month or year for administering a loan, also called service or administration fees.
A worked sense of it: imagine two loans both advertised at the same interest rate. The first has no ongoing fee. The second charges a monthly account fee. The second loan’s comparison rate would sit higher, even though the advertised interest rates match. That gap is exactly what the comparison rate is built to reveal.
If you want to understand the headline rate first, our guide to interest rates for first home buyers covers where rates come from and how they move.
What the comparison rate does not capture
The comparison rate is a strong starting point, but it is not the whole picture, and treating it as the only number could steer you wrong. A few things to keep in mind:
- It is built on a set of standard assumptions, so it may not reflect your loan size, your term, or how you actually use the loan.
- It does not value loan features. An offset account, a redraw facility, or the ability to make extra repayments could matter a great deal to you and may not show up in a single percentage.
- One-off or situational costs, such as a break fee if you exit a fixed loan early, sit outside the everyday comparison.
MoneySmart makes the broader point that some loan features could cost you more, and it is worth asking whether it is worth paying extra for features you may never use. The comparison rate helps you read cost. It does not decide whether a feature earns its keep for your situation.
When you read comparison rates, make sure you are comparing the same loan amount and term, as MoneySmart advises. The figure is only meaningful when the loan parameters match, so a comparison rate on one loan size cannot be lined up against a comparison rate on another.
How to compare home loans properly
MoneySmart suggests weighing up three things when you compare home loans: the interest rate, including variable versus fixed, the fees such as the application fee and ongoing fees, and the loan features.
The variable versus fixed choice changes how you read all of this.
| Fixed rate | Variable rate | |
|---|---|---|
| Budgeting | Can make budgeting easier because you know what your repayments will be, and fewer loan features could cost you less. | Repayments could go up or down, which makes budgeting harder. |
| Flexibility | You may not be able to make extra payments during the fixed term. | May offer more loan features and greater flexibility. |
| Switching later | It may cost more to switch loans later if you are charged a break fee. | Usually easier to switch loans later if you find a better deal. |
| If rates fall | You will not get the benefit if interest rates go down. | Your rate can move down with the market. |
A sensible way to read a loan, in order:
If you want to put real numbers against your own situation, the MoneySmart mortgage calculator and mortgage switching calculator are useful starting points, and a rate check can show how your current or proposed rate stacks up.

You can use a rate check to see whether the rate on offer looks competitive once you read it alongside the comparison rate.

It also helps to see what those rates turn into each month, which our guide to first home loan repayments walks through.
