6 in 10 Car Buyers Are Now Rolling Old Debt Into Their New Loan. That’s a Record.

New data from Kelley Blue Book puts a number on something that’s been building for a while: 6 in 10 car buyers now roll negative equity from their old loan into their new one when they trade in — the highest share on record.

Negative equity, sometimes called being “upside down” on a loan, means you owe more on your current car than it’s actually worth. When you trade that car in for a new one, the gap doesn’t disappear. It gets added on top of your new loan balance, meaning you start the new loan already behind before you’ve driven it off the lot.

Why this keeps getting worse

Three things are stacking on top of each other right now.

Tariffs pushed new car prices to record highs. A 25% tariff on imported vehicles took effect in April 2026, followed by a 25% tariff on imported auto parts in May. Because roughly half the U.S. new car market is affected in some way, the average new car price has climbed to $49,758 — up more than $1,300 in the first quarter alone, with some estimates projecting another $4,000 to $6,000 in increases before the year is out.

Loan terms keep stretching to make payments look affordable. A record number of new auto loans are now stretched to 72 months or longer. That lowers the monthly payment, which is what most buyers focus on — but it also means you spend years owing more than the car is worth, since cars depreciate faster than a 6-year loan pays down principal in the early years.

People need to replace cars whether or not the timing is good. A breakdown, an accident, a growing family — life doesn’t wait for auto loan rates or tariff policy to cooperate. When the old car has to go and the new one costs $4,000 more because of a tariff, the math often only works by extending the loan further, which deepens the negative equity problem for the next trade-in too.

The trap, in plain numbers

Say a $4,000 tariff-driven price increase gets added to a 72-month loan at 6.5% APR. That’s roughly $74 more per month, and about $1,328 in extra interest over the life of the loan — before you even account for any negative equity rolled in from a trade-in. Stack a few years of this pattern and the gap between what you owe and what the car is worth only widens.

How to check where you actually stand

Before you trade in or shop for a new car, get two numbers side by side: what you still owe on your current loan, and what your car is actually worth. Kelley Blue Book and Edmunds both offer free trade-in value estimates. If the payoff amount is higher than the trade-in value, that gap is your negative equity — and it’s worth knowing the exact figure before you walk into a dealership, not after a salesperson tells you what it is.

What actually helps if you’re upside down

Keep the car longer if you can. Every month you wait, your loan balance drops and (usually) the car’s value stabilizes. Even six extra months can meaningfully close the gap.

Make extra principal payments if your loan allows it. Paying down principal faster is the most direct way to shrink negative equity, since it attacks the actual problem instead of the monthly payment.

Avoid stretching the next loan to cover the gap. It’s tempting to roll negative equity into a 72- or 84-month loan to keep the payment low, but that’s exactly the pattern that created the record 60% figure in the first place. If a dealer’s financing only “works” by extending the term, that’s a signal to slow down, not a green light.

Consider whether you need to trade in at all. If your current car is running fine, repairing it or simply keeping it another year or two is often far cheaper than trading into a $49,000+ new car with tariff costs baked in.

The bigger picture

None of this means car buyers did anything wrong. Prices went up because of policy decisions outside anyone’s control, and people still need working transportation. But the record-high negative equity number is a warning sign worth taking seriously if you’re anywhere close to trading in — the gap you’re rolling forward today tends to be smaller than the one you’ll be rolling forward next time, unless something changes in between.
