If you are trading in a car you still owe money on, there is roughly a one-in-three chance you owe more than it is worth. Roll that gap into a new loan and you start the next car already behind, paying interest on metal you no longer own.
New Edmunds data for the first quarter of 2026 puts it plainly: 30.9% of trade-ins toward a new car carried negative equity, the highest share for any quarter since early 2021. Negative equity is the gap when your loan balance is bigger than the car is worth. The average gap hit $7,183, the highest ever recorded for a first quarter. These were not reckless buyers. Most bought at pandemic-era prices that have since come back to earth.
Here’s the catch. About 90% of these underwater buyers rolled the gap into a loan of at least 72 months, and 43% stretched to 84 months. The average term ran 77.4 months at a 7.9% rate, against 70.3 months and 6.9% for everyone else. Longer loan, higher rate, and you are quietly paying off the old car inside the new one.
30.9%: the share of trade-ins that were underwater in early 2026, by an average of $7,183 (Edmunds).
The numbers downstream are worse than they look. A buyer who rolled negative equity into the new loan financed $55,970, about $12,071 more than the typical buyer. The monthly payment averaged $932, $159 above the market. Over the life of the loan they will pay $15,663 in interest, against $9,592 for everyone else. That is roughly $6,000 in extra interest to avoid dealing with the gap today. Questionable on a good day. Usually just dumb.
If you are underwater, the cleanest move is to not trade yet. Keep the car, keep paying, and let the balance fall below the value. Check your number first: ask your lender for the payoff amount and get a fair market value before you walk onto a lot.
If you have to buy, cover the gap with cash instead of rolling it. Rolling it forward only moves the problem into a bigger, longer loan. And shop the loan itself, not just the car, because a single point of rate on a $40,000 loan is real money. Compare lenders on our best loan rates page and run the terms through our loan calculator before you sign anything.
One more sign of the trap: the average age of an underwater trade-in reached 4.3 years, the highest on record, so holding the car longer is no longer enough to close the gap on its own. More than one in four of these deals now rolls over $10,000 in old debt. The longer loan keeps the monthly payment looking affordable while the total cost climbs. Don’t take the bait.
