WICHITA FALLS, TX — A Texas dealer’s trade-in problem shows how easily a car loan can become a trap. A customer arrived hoping to lower a $1,472 monthly payment on a 2025 Ram 3500 with only 14,000 miles, but he still owed about $79,000 on a truck worth about $58,000.
That left him roughly $21,000 underwater, meaning the loan balance was far above the vehicle’s value. With no cash down, the buyer had little room to reset the deal, and the dealer advised him to keep the truck and keep paying. The case is extreme, but dealers and finance experts say the pattern behind it is becoming more common as shoppers focus on monthly payments instead of total cost.
How a trade-in can turn into a debt carryover
Negative equity is not new, but the size of the shortfall has grown. Edmunds says the average amount of negative equity on underwater trade-ins rose from $4,576 in 2015 to $6,884 in the second quarter of 2026. About one in four underwater trade-ins now carries more than $10,000 in negative equity.
Josh Letsis, who owns Always Auto in Wichita Falls, says that kind of debt used to be much less common outside luxury vehicles. He said balances around $20,000 once tended to show up in high-end Mercedes models, not in pickup trucks.
When a borrower trades in a vehicle before the loan is paid down, any unpaid balance usually gets rolled into the next loan. That raises the new balance, adds more interest, and makes it harder to get back to even the next time around.
Rising prices and longer loan terms are making the gap wider
Vehicle prices have climbed sharply since 2019, which has helped push more borrowers into deeper negative equity. Edmunds says the average new-vehicle transaction price has increased about 31%, from $37,310 to $48,963.
At the same time, loan terms have stretched out. Federal Reserve data showed the average new-car loan at finance companies was about 60 months in 2010 and roughly 65 months five years later. Today, Edmunds says the average new-car loan lasts about 70 months, and about one in four buyers financing a new vehicle now takes out an 84-month loan or longer.
Letsis said 72-month financing has become standard in many deals, even on used cars, and he regularly sees 78-month and 84-month terms. Longer terms lower the monthly bill, but they also slow the pace at which borrowers build equity.
Why trading every few years can snowball into permanent car debt
The risk grows when borrowers replace cars before they have paid down much of the balance. Edmunds says the average trade-in age for vehicles with negative equity is four years, while Kelley Blue Book says a typical new car has lost nearly half its original value by that point because of depreciation.
That mismatch matters because early payments go heavily toward interest. With a longer loan, the borrower may owe more than the car is worth for a longer stretch, especially if the vehicle is traded in after only a few years.
Charles Chaffin, a professor at Iowa State University who studies financial psychology, says repeated trade-ins can create what he calls “permanent car debt.” The borrower keeps rolling old debt into new loans and never fully escapes the cycle of financing a vehicle.
Monthly payment shopping can hide the real cost of ownership
Experts say many buyers start with the payment they think they can handle and work backward from there. Chaffin calls that anchoring, where a shopper fixates on a monthly number instead of the total amount being financed.
Ivan Drury, director of insights at Edmunds, said this mindset makes it easier to justify moving from a $30,000 car to a $35,000 one if the payment only rises by a few dollars a month. The problem is that a manageable payment can still hide a much larger long-term expense.
On a $50,000 loan at a 7% fixed annual percentage rate, stretching repayment from 60 months to 84 months can save more than $200 a month, but it adds about $4,000 in interest over the life of the loan. Drury said the average borrower now pays about $10,000 in interest over the life of an auto loan.
What car owners can do before they roll debt into the next loan
Not every long auto loan ends in trouble, and not every trade-in creates negative equity. The problem is greatest when the loan lasts longer than the buyer keeps the car. Drury said some shoppers sign for seven years but are back in the market in five years or even sooner.
Andrea Anderson, a sales consultant at Andrews Cadillac Brentwood in Tennessee, said buyers sometimes want a newer car for technology, warranty coverage, changing family needs or simple preference. But if they trade too soon and keep focusing on the same payment, they may miss how much extra debt is being carried forward.
Anderson said a lease may make more sense for people who know they want a new vehicle every few years. Letsis also said keeping a vehicle longer can help borrowers close the gap between what they owe and what it is worth, and Jeff Judge, a certified financial planner with Chesapeake Financial Planners, said ownership eventually frees up money for other goals once the loan is gone.
