Two car finance quotes sit on the desk. One shows a comparison rate; the other, from a business lender, shows none. Here is what the figure includes, what it leaves out, and how to compare the quote that does not carry one.
Quick Answer
A comparison rate rolls a loan's interest rate and most of its fees into one annual figure, calculated on a standard loan amount and term, so you can compare regulated car and home loans like for like. Most ABN car loans used mainly for business carry none, so you compare those on total cost instead. The comparison rate glossary entry has the short definition.
Also called: comparison interest rate, true rate, total cost rate. All three mean the same disclosed figure; an annual percentage rate (APR) is related, but it is not the regulated Australian comparison rate.
What is a comparison rate?
A comparison rate is a single annual percentage that puts a loan's interest and most fees in one figure, so two loans with different rate and fee mixes can be lined up against each other. A loan with a low headline rate and heavy fees can end up with a higher comparison rate than a loan with a slightly higher rate and no fees, and that is exactly the trap the figure exists to expose.
On a regulated consumer car loan, the lender has to show it. Moneysmart's guidance at the time of writing is that lenders must give you the comparison rate on car loans, and that you should only line up comparison rates calculated on the same loan amount and term. Its car loans guide is the government's own explainer.
The obligation comes from consumer credit law, which matters for business owners. A car loan in your own name for a family car is regulated, so a comparison rate appears. A chattel mortgage or ABN car loan used mainly for the business usually sits outside that law, which is why section six of this insight exists.
How is a comparison rate calculated?
A comparison rate is calculated by taking the interest and the fees that can be known up front, spreading them over a standard loan amount and term, set by regulation, and expressing the result as one annual rate. Because every lender uses the same example, the numbers are comparable even when the loans are not built the same way.
The regulation sets one standard example for car and personal loans and a larger, longer one for home loans, and the lender's disclosure states which example its figure uses. Your loan will almost never be exactly that size or length, which is why the figure is a comparison tool rather than a quote of what you will pay.
The bigger question is which costs make it into the calculation. Fees that are certain when the loan is written usually go in. Costs that depend on what you do later, or that are set by government, usually stay out.
| Cost | Usually inside the comparison rate? | Notes |
|---|---|---|
| Interest | Yes | The base of the calculation, at the rate on the loan. |
| Establishment fee | Yes | Known at the start, so it is usually counted. This is where fee-heavy loans show up. |
| Ongoing monthly fees | Yes | Counted across the standard term, which is why a small monthly fee can move the figure. |
| Balloon payment | Usually not in the advertised example | The standard example is usually worked without one, so it will not show what a balloon does to your own total cost. |
| Early payout fees | No | They depend on whether and when you pay out early, so they cannot be known up front. |
| Late payment fees | No | Default charges depend on what happens during the loan, not on the loan itself. |
| Dealer or introducer commission | Partly | A broker or introducer fee charged on the contract is usually counted. Commission paid to the dealer by the lender is built into the rate and is not shown on its own. |
| Government charges | No | Duties and registration charges set by government are usually left out, even when they are added to the loan. |

What does the comparison rate warning mean?
The comparison rate warning means the figure is true only for the example it was calculated on, and that a different amount, a different term or fees left out of the calculation will produce a different rate. Every advertised comparison rate has to carry it, which is why it appears in small print under almost every car and home loan ad.
In substance it says three things. The rate applies only to the example given. Different amounts and terms give different comparison rates. Some costs, such as early repayment fees, and some savings, such as fee waivers, are not included but can still change what the loan costs you.
The warning is the reason your own quote rarely matches the ad. Borrow more over a longer term than the standard example and the same fees are spread over a bigger balance and more months, so the effective rate moves. Borrow a small amount over a short term and a fixed establishment fee weighs more heavily, so the effective rate usually rises. Read the comparison rate warning as an instruction to compare like for like, not as boilerplate.
How does a comparison rate differ from the interest rate, a variable rate and an APR?
A comparison rate differs from the interest rate because it adds most fees to the interest, while the interest rate on its own shows only what you pay to borrow the money. The other two terms describe something else again, and mixing them up is where a lot of quote confusion starts.
- Interest rate. The annual rate charged on the balance. On an Australian credit contract this is the annual percentage rate, and it does not include fees.
- Variable or fixed rate. A variable rate can move during the loan; a fixed rate stays put for a set period. Either type of loan can also have a comparison rate.
- APR overseas. In some other countries an APR folds certain fees in, which is why people searching overseas sites assume APR and comparison rate are the same thing. In Australia they are not.
- Factor rate. Some short-term business lenders quote a flat multiple of the amount borrowed. It looks small and is not an annual rate at all; our factor rate to APR worked example converts one.
Why can a low advertised car loan rate cost more overall?
A low advertised car loan rate can cost more overall because the rate is only one part of the price: a balloon, extra fees from the parties who arranged the loan, or a car price that carries the cost of the finance offer can all sit outside the headline number.
The balloon. Moneysmart notes at the time of writing that a balloon payment makes monthly repayments smaller, but you repay the lump sum with interest, so the total cost of the loan is generally higher. A balloon is often set against the car's expected residual value, and if the car is worth less than the balloon when it falls due, the gap is yours to fund.
The people in the middle. A loan arranged at the dealership can involve the lender, a broker and the dealer as introducer, and Moneysmart warns that the fine print may mean you pay fees to several of them. A broker fee must be disclosed on the finance contract. Ask who is involved and what each one charges before you sign.
The price of the car. A subsidised dealer rate is often paid for elsewhere, usually in less room to negotiate on the drive-away price. Ask for the price with and without the finance offer, and compare the total you pay across the term, not the rate on the brochure.
Why do business car loans and chattel mortgages often have no comparison rate?
Business car loans and chattel mortgages often have no comparison rate because the obligation to show one comes from consumer credit law, and a loan used wholly or predominantly for business usually falls outside that law. That is why most ABN holders see no comparison rate on most business car quotes, even from lenders who show one on every personal car loan.
The line is drawn by what the money is mainly used for, not by whether you hold an ABN. A sole trader buying a ute used mainly for the business is usually on a business contract. The same person buying a family car in their own name, for mostly private use, is usually on a regulated consumer contract, comparison rate and all. The responsible lending glossary entry explains which loans the consumer rules cover.
A missing comparison rate is not a red flag on its own. It does mean the quote has to be read differently, because the lender is not required to boil its fees into one number for you. The chattel mortgage rates guide answers why a business quote shows no comparison rate in more depth, and the ABN car loan guide covers how a business-use car loan differs from a personal one. If the car is mainly a work vehicle, a chattel mortgage is the usual structure.
How should an ABN holder compare car finance quotes without a comparison rate?
An ABN holder should compare car finance quotes without a comparison rate by rebuilding the comparison themselves: same amount, same term, then total repayments, fees, balloon and payout cost side by side. It takes ten minutes with the quotes in front of you and catches most of what a headline rate hides.
- Match the amount and term. Ask each lender to quote the same amount financed over the same term, with or without the same balloon.
- Add up total repayments. Monthly repayment times the number of months, plus the balloon. This is the single most useful number on a business quote.
- List every fee. Establishment, monthly, broker or introducer, and any fee for registering the security.
- Price the exit. Ask what it costs to pay the loan out after one, two and three years. Some business loans charge little; others keep most of the interest.
- Check what drives the price. The age of the car, the strength of the file and whether there is a deposit usually move the price more than the lender's brand.
Inside the comparison rate
- Interest across the standard term
- Establishment fee
- Ongoing monthly or annual fees
- A broker or introducer fee charged on the contract
Outside it
- A balloon on your actual contract
- Early payout and break costs
- Late payment and default fees
- Government duties and registration charges
Total repayments, fees, balloon and payout: line those four up and you have a fairer comparison than a comparison rate would give you on a business quote. The ABN car loan cost stack walks through each layer, and the ABN car loan calculator gives an indicative repayment to check a quote against.

A comparison rate puts interest and most fees in one figure, worked out on a standard loan amount and term, and regulated consumer car and home loans must show it. It leaves out balloons on your own contract, payout costs, default fees and government charges, and the comparison rate warning says it only holds for the example given. Most business car quotes carry no comparison rate at all, because the law that requires one does not usually reach a loan used mainly for business.
Key takeaway: on a personal car loan, compare comparison rates on the same amount and term; on a business quote, compare total repayments, fees, balloon and payout instead.Frequently Asked Questions
A good comparison rate for a car loan is one that sits below the other quotes you hold for the same amount and term, rather than one fixed number that suits everyone. What you are offered depends on whether the loan is secured, the age of the car, your credit file and whether the loan is personal or business. Compare like for like using the comparison rate, and on a business quote compare total cost, as the ABN car loan guide explains.
A 4.9 per cent comparison rate means the loan's interest and its included fees, spread over the standard example, cost about the same as a loan charging 4.9 per cent a year with no fees at all. It is worked out on a standard amount and term, so your own loan can come out higher or lower. Treat the figure as an illustration for comparing loans, not a rate you are guaranteed; the comparison rate glossary entry covers the basics.
The difference between an interest rate and a comparison rate is that the interest rate shows only the cost of borrowing the money, while the comparison rate adds most of the loan's fees to it. That is why a loan with a low interest rate and high fees can have a higher comparison rate than a plainer loan. On an Australian contract the interest rate is the annual percentage rate, which does not include fees.
A comparison rate is not better or worse than a variable rate, because the two measure different things. A variable rate is a type of interest rate that can move during the loan, while a comparison rate is a disclosure figure that adds fees to the rate. A variable rate loan can carry its own comparison rate, and that is the number to line up against other loans.
A balloon payment does change what the loan costs, but the advertised comparison rate is usually worked out on a standard example without one, so it will not show the effect. A balloon payment lowers the regular repayments, and the total cost is generally higher because you repay the lump sum with interest. Ask each lender for total repayments on your actual amount, term and balloon.
