Auto Loan APR: What the Number Includes and How to Compare It

APR and interest rate are not the same

The interest rate is the price of borrowing the money itself. The APR adds the cost of fees the lender charges as a condition of the loan and spreads everything over the term as one yearly percentage. If a loan has no such fees, the two numbers match. If it does, the APR is higher.

That is why APR, not the interest rate, is the figure to compare. Two loans can carry the same 7% rate, but if one charges a loan fee and the other does not, the first costs more and its APR shows it.

Under Regulation Z, the finance charge covers interest and charges imposed as a condition of the credit, such as loan fees, credit report fees and premiums for insurance that protects the lender against default. Charges you would also pay in a cash purchase, such as sales tax, are not finance charges. GAP waivers, a kind of debt cancellation coverage, can be left out of the finance charge only if the lender does not require them, discloses that and the price in writing, and you sign or initial a request for the coverage. When an optional product is financed this way, it raises the amount financed rather than the APR, but you still pay interest on it.

Where to find the APR on your contract

The Truth in Lending Act and its rule, Regulation Z, require the creditor to give you these figures in writing before the deal is final, grouped together and set apart from everything else. On a car contract they usually sit in a box near the top.

• Annual percentage rate: the cost of credit as a yearly rate.
• Finance charge: the cost of credit in dollars, interest plus fees counted as finance charges.
• Amount financed: the credit actually provided to you or on your behalf.
• Total of payments: what you will have paid after every scheduled payment.
• Payment schedule: the number, amount and timing of payments.

For a typical loan, the APR shown must be within one-eighth of one percentage point of the true figure. If the rate you agreed to talk about does not match the APR in that box, stop and ask why before you sign. The final chapter, on the retail installment contract, walks through the rest of the document.

Worked example: a fee raises the APR

Suppose you need $25,000 for 60 months at a 7% interest rate. With no fees, the payment is $495.03 and the APR is 7%. Now suppose the lender charges a $600 loan fee and you finance it, so the 7% rate applies to $25,600.

The rate on the note is 7% in both cases, but the fee is a cost of credit, so it is counted in the finance charge and the APR rises to about 8%. The payment goes up by $11.88 a month.

How dealer markup shows up in the APR

When you finance at the dealership, the dealer sends your application to lenders and sells the signed contract to one of them. The lender tells the dealer the lowest rate it will accept for your credit, often called the buy rate. The dealer may write the contract at a higher rate and keep part of the difference as compensation. You see only the final APR on the contract.

In this illustration the markup costs $21.31 a month and about $1,278.60 over five years. You cannot see the buy rate, but the CFPB suggests asking whether there were other offers with lower rates, and the FTC advises negotiating the APR the way you negotiate the price. You can also protect yourself by arriving with a preapproval and asking the dealer to beat it. Our page on dealer financing covers how the arrangement works.

What APR to expect for your credit

The Federal Reserve's data for the same quarter show commercial banks averaging 7.14% on 60-month new-car loans and finance companies 6.3%. Those figures were collected before the Fed raised its target range in September 2026, so quotes this fall may run higher. Low-rate programs sponsored by carmakers can be lower, but the FTC notes they can come with strict requirements, and a rebate is not always built into the price you are offered. Ask whether taking the low rate means giving up a rebate, and compare both ways with the car payment calculator.

Steps to compare APR offers

1. 1 Compare at the same term. A 72-month APR and a 60-month APR are not like for like.
2. 2 Ask for the APR, not just the rate. If a lender quotes only a rate, ask which fees are added.
3. 3 Check the amount financed. Add-ons and negative equity raise it without changing the APR.
4. 4 Compare total of payments as well as APR, since a longer term can cost more even at a lower rate.
5. 5 Match the contract to the quote before you sign, line by line.
