Typical Car Loan Interest Hits $10,100 on New Vehicles and $10,900 on Used

• Cox Automotive puts the interest on a typical new-vehicle loan at $10,100 and on a typical used-vehicle loan at $10,900 over the life of the loan, up 79 percent and 96 percent from 2019.
• Used-vehicle down payments have dropped to nearly 0 percent of a typical loan, and the all-in cost of buying has climbed 37 percent for new and 43 percent for used versus 2019, against a roughly 30 percent rise in vehicle prices alone.
• A shorter term, a bigger down payment and a pre-approved quote from a bank or credit union cut the interest bill, and comparing total interest instead of the monthly payment shows what a loan really costs.

Interest Has Grown Faster Than the Price of the Car Itself

A buyer who finances a typical new vehicle now pays $10,100 in interest before the loan is cleared. A used-vehicle buyer pays $10,900. Jeremy Robb, chief economist at Cox Automotive, published both figures in the company’s Auto Market Weekly Summary on November 2, and they sit on top of the sticker price, the sales tax and the fees.

The growth is the story. Work backward from Cox’s percentages and the interest on a typical new-vehicle loan stood at about $5,640 in 2019, so the bill has risen by about $4,460. The used-vehicle figure stood at about $5,560 and has risen by about $5,340. Both derived numbers come from the Cox percentages, and they show a used-car loan carrying close to twice the interest it did seven years ago. Cox’s Auto Market Brief podcast, Ep. 20 of October 27, makes the same point for used vehicles: the interest has nearly doubled against 2019.

Prices climbed too, but by far less. Vehicle prices alone have risen roughly 30 percent over the same stretch. Add the cost of borrowing and the all-in cost of a new vehicle is up 37 percent and a used one is up 43 percent versus 2019, on Cox’s own measure of the full purchase. Cox names the cost of money as one factor behind the extra 7 points on new and 13 points on used.

That gap explains why a monthly payment can look manageable while the total keeps growing. The payment is one number on a contract. The interest is the sum of every payment above the amount borrowed, and it is the line most buyers never add up.

What Lenders Charge, and What a Longer Term Does to the Bill

The Federal Reserve’s G.19 consumer credit release gives the lender side of the market. The latest edition posted, issued October 7, covers August 2026. Commercial banks charged an average of 7.54 percent on 60-month new-car loans and 7.17 percent on 72-month loans, measured in the first week of August. The previous quarterly reading, taken in May, had those averages at 7.14 percent and 6.97 percent, so the 60-month rate rose 0.40 points and the 72-month rate 0.20 points in one quarter. The August readings sit below the same measure a year earlier, 7.64 percent for 60 months and 7.80 percent for 72 months, and below the 2024 averages of 8.16 percent and 8.29 percent. The 2021 average for both terms was 4.82 percent, so a 60-month loan now costs 2.72 percentage points more than it did in 2021.

Finance companies, which cover most captive and non-captive lenders, reported a 6.3 percent average new-car rate for the second quarter of 2026, a 67-month average maturity and an average amount financed of $41,705. The Fed’s tables also show $1,574.6 billion in motor vehicle loans outstanding at the end of June, up $14.9 billion from the end of March. The Fed generally issues the G.19 on the fifth business day of each month, and the next edition covers September, so these averages will update when it posts.

Rates tell half of it. The term decides the rest. Take a $40,000 loan at the Fed’s August 60-month bank average of 7.54 percent. This is an illustration, with the rate held constant so that only the term changes, and the Fed publishes no 84-month rate.

Over 60 months the payment is $802.28 and the interest is $8,137. Stretch it to 72 months and the payment drops to $692.38 while the interest climbs to $9,851. At 84 months the payment falls to $614.32 and the interest reaches $11,603. Choosing 84 months over 60 saves $187.96 a month and adds $3,466 in interest. The buyer who picks the lowest payment pays the most.

Cox’s $10,100 for a typical new loan is the company’s own measure and runs above what the Fed’s finance-company averages produce. A $41,705 loan at 6.3 percent over 67 months works out to a $739.96 payment and $7,872 in interest. Treat these examples as a way to test your own numbers. Your rate, amount and term will differ.

Down payment moves the total as well. On the same $40,000 loan over 72 months, putting $4,000 down leaves $36,000 to finance, a $623.14 payment and $8,866 in interest, which is $985 less. Put $8,000 down and the payment is $553.90, the interest is $7,881 and the saving is $1,970. The average used-vehicle down payment has fallen to nearly 0 percent of a typical loan, which leaves that saving unclaimed.

Defaults, Slower Sales and the Strain Behind the Numbers

The pressure shows up in who is keeping up with the bills. Auto loan rates moved higher in October, Cox says in Ep. 20, and defaults are climbing in every credit tier, subprime through prime-plus. Our report on subprime borrowers falling behind covers the weakest end of that range. The Cox finding is that the strain now reaches borrowers with strong credit as well.

Household budgets explain part of it. Personal income ran 4.1 percent above a year earlier in September while personal expenses ran 6.3 percent above. The personal saving rate fell to 3.8 percent in September, against 5.1 percent a year ago. The PCE price index, the Fed’s preferred inflation gauge, rose 3.6 percent. The Fed held interest rates steady at its October meeting, with two voting members dissenting in favor of a hike, and Robb writes that the inflation data argue for higher rates. Plans to buy an auto softened to 11.1 percent in the Conference Board’s October survey.

New-vehicle sales felt it. Cox’s October forecast, issued October 27, expected a seasonally adjusted annual rate near 16.1 million. Jonathan Gregory, a senior director at Cox Automotive, said then: “October sales should remain on a path the market has consistently followed since March, which is basically a low-mid 16 million pace. Healthy fleet sales, wealthier new-vehicle buyers and more access to credit are all keeping this market relatively strong in the face of many headwinds. Stubbornly high gas prices and historically low consumer confidence have not impacted the new-vehicle market as much as one might expect. New-vehicle buyers today are more affluent, so they may not be as impacted by inflationary pressures as other consumers.”

The November 5 update came in lower. Initial estimates put October at 15.5 million, below the 15.7 million of a year ago and the 16 million of September, the slowest of any month after January. Volume of about 1.324 million units was up 2.9 percent from last October, though well under the forecast. Fleet sales rose nearly 6 percent, which places the shortfall in retail demand, and Cox ties it in part to what it calls an upward trend in loan rates last month. Cox describes October as a bump in the road and not a change of direction, and its full-year forecast stays at 16.1 million units with more downside risk than before.

Owning the car costs money beyond the loan. Cox’s Ep. 20 puts the year-over-year rise in maintenance and repair costs at 5.8 percent, and parts and service now produce 54 percent of the gross profit at the publicly traded dealer groups. The same squeeze runs through why cars cost so much in 2026, where tariffs, prices and financing stack up.

Steps That Cut the Interest Before You Sign

Start with the lender before the dealership. The Consumer Financial Protection Bureau (CFPB) advises getting pre-approved by a bank or credit union, which produces a quote with an interest rate, loan length and maximum amount. That quote lets you compare any offer the dealer brings. A dealer-arranged loan carries the lender’s “buy rate” plus extra interest that pays the dealer for handling the financing, and the CFPB notes that dealers generally contact roughly five lenders and then present one loan, so you can ask whether the other offers were cheaper. Banks and credit unions tend to be the cheaper route, so the dealer markup drops out. You do not have to bank with the lender you ask.

Shopping for rates costs little. The CFPB says credit inquiries made within a 14 to 45 day window count as a single inquiry, so comparing several lenders has a limited effect on your credit.

Ask for the total interest in writing, along with the monthly figure. The Truth-in-Lending disclosures a lender must give you before you agree to a loan list the finance charge, the amount financed, the total of payments and the total sale price. The finance charge is the cost of the credit, and the total of payments minus the amount financed gives you the same number as a check. Run the same comparison at 60, 72 and 84 months and the cost of the longer term is on the page.

Choose the shortest term whose payment fits your budget, and put down as much as you can. If you are trading in a car you owe more on than it is worth, the CFPB warns that rolling that negative equity into the new loan makes the new loan more expensive. Find the payoff amount on the old loan and the trade-in value before you walk in, and get trade-in offers from more than one dealer. Buyers heading to a used lot can pair this with checks before buying a used car.

The simple test is the one Cox’s numbers set up. If the interest on your loan runs near $10,100 for a new vehicle or $10,900 for a used one, the car costs that much more than the sticker says. Every point of rate and every extra year on the term shows up in that total.
