How to Read an Auto Loan Offer: APR, Term, Amount Financed and Total Cost

A loan offer can look like one number: the monthly payment. But the payment depends on the price, the APR, the term and everything rolled into the loan. This guide explains each line using Consumer Financial Protection Bureau (CFPB) guidance. It is general education, not financial advice, and Car Bills Explained is not a lender or loan broker.

What is the difference between the interest rate and the APR?

The CFPB explains that a loan’s interest rate is the cost you pay the lender for borrowing money, while the Annual Percentage Rate (APR) is a measure of the interest rate plus additional fees charged with the loan, such as origination charges. Both are shown as a percentage. Because the APR includes those fees, it is a broader measure of what the loan costs you.

The federal Truth in Lending Act (TILA) requires lenders to give you written disclosures about the important terms, including the APR, before you are legally bound to pay the loan. Since every lender has to show it, the APR is the number to line up when you compare offers. The CFPB adds one condition: compare APRs for loans with the same term.

What are the main numbers on the Truth in Lending disclosure?

• Annual percentage rate (APR): the yearly cost of the credit, including certain fees.
• Finance charge: the cost of the credit in dollars over the whole loan.
• Amount financed: the amount of credit provided to you. Anything rolled into the loan, such as taxes, fees, a service contract or GAP, increases it.
• Total of payments: what you will have paid after making every scheduled payment.
• Payment schedule: the number of payments, the amount of each and when they are due.

The CFPB also describes a total cost figure: what you pay to buy the vehicle, including principal, interest and any down payment or trade-in, over the life of the loan. If the total looks higher than you expected, find out which line is driving it before you sign.

How does the loan term change what you pay?

The term is the length of the loan in months. The CFPB says a shorter term reduces your total loan cost, while a longer loan can reduce your monthly payment but means you pay more interest over the life of the loan. A longer loan also keeps you at risk of negative equity for longer, meaning you owe more than the car is worth. The CFPB’s example: if you owe $10,000 and the car is worth $8,000, you have $2,000 of negative equity, and it has to be paid off if you trade the car in for another one.

When two offers have different terms, compare the total of payments as well as the APR. A low monthly payment on a long term can cost more in total than a higher payment on a shorter term.

Is the rate fixed or variable?

With fixed-rate financing, the rate doesn’t change over the life of the loan, so you can see each payment and the total in advance. With variable-rate financing, the CFPB explains, the rate can change with an index such as the prime rate, so the payment can go up or down, and the longer the term, the more time there is for rates to rise. Check which one your offer is.

How does dealer-arranged financing work?

When you finance through a dealership, the dealer usually sends your application to one or more lenders. The CFPB defines the buy rate as the interest rate a lender quotes to your dealer when you apply for dealer-arranged financing. The rate the dealer offers you can differ from that buy rate. The CFPB also notes that dealers and lenders are not required to offer you the lowest rate available to you.

Your loan can also be sold. The CFPB explains that an assignee is a company that buys your auto loan, for example a bank that buys it from the dealer, and you then owe the money to that company. Keep every page you sign so you know the terms that came with the loan.

How can you compare offers before you go to the dealer?

• Get preapproved. The CFPB suggests getting preapproved by a bank or credit union, so you can show the rate you were offered and ask other lenders or the dealer to compete.
• Check your credit reports. Your credit history affects the rate you are offered. Reports are free every week at AnnualCreditReport.com; see our guide to checking your credit before a car loan.
• Compare like with like. Same loan amount, same term, then compare APR and total of payments.
• Negotiate. The CFPB says the interest rate, the term and add-ons can be negotiated, along with the price of the car.

How do add-ons change the offer?

Service contracts, GAP, credit insurance and items such as window tinting or tire and wheel protection are often added in the finance office. The CFPB says these add-ons are optional and their prices are negotiable, and that including them in the loan increases both the amount you borrow and your monthly payment. Before you sign, the CFPB suggests asking whether the loan includes charges for optional products. If you are told a product is required, ask where the contract says so; if it truly is required, its cost must be counted in the finance charge and APR. Details are in our guide to dealer add-ons and GAP.

Can you pay the loan off early?

Ask whether the loan has a prepayment penalty, a fee for paying it off early. The CFPB suggests asking the lender or dealer, and negotiating to remove it if there is one. If you pay off early, refinance or sell the car, the CFPB notes you may be entitled to a refund on optional products such as GAP or a service contract.

What should you check right before you sign?

• The price, down payment and trade-in value match what you agreed to.
• The APR, term and monthly payment match the offer you accepted.
• Every add-on is one you chose, at the price you agreed to.
• All blanks are filled in, and you get a full copy of everything you sign.

If something is wrong after the sale, start with the dealer and lender in writing. If that doesn’t resolve it, you can submit a complaint to the CFPB; see complaints and where to get help.
