How to sell a car with negative equity

If you owe more on your auto loan than your car is worth, you have negative equity. When you sell, the buyer’s payment won’t fully cover your payoff amount, so you’ll need to contribute the difference. Dealers may let you roll the shortfall into a new loan, but it’s usually expensive and adds more debt.

This guide helps you calculate how much you’ll owe and outlines your options for selling a car with negative equity.

Step 1: Find your loan balance

Log in to your lender’s online portal or check your latest statement. Look for the “current balance” or “payoff amount.” This is what you must pay for the lender to release the lien on your title. No buyer can take ownership until the lien is cleared.

Write down this number. You’ll use it to calculate your equity.

Step 2: Estimate your vehicle’s value

Check pricing guides like Kelley Blue Book or NADA. Make note of both the private-party value and the trade-in value. You can ignore “retail price,” which reflects what dealers charge.

Online guides aren’t perfect, especially for unusual vehicles or volatile markets. As a cross-check, browse listings on Facebook Marketplace, Craigslist, and enthusiast sites to understand current asking prices. These won’t tell you final sale prices, but large gaps between listings and book values can signal a price adjustment is needed.

Step 3: Calculate your equity

Use this simple formula:

If the result is negative, you’re underwater on your loan. You’ll need to pay that amount to complete the sale.

Private party sales usually bring higher prices than trade-ins, which means you contribute less money when you sell. You can see the difference immediately by running the formula with both the private-party and trade-in values. In most cases, selling privately saves at least 20 percent over a trade-in.

Selling a financed car privately takes extra steps

Buyers expect a clear, lien-free title. Dealers can handle the payoff process internally, but that convenience comes at the cost of a lower trade-in value.

Your lender might allow you to sell privately and coordinate the payoff directly with your buyer, though the process varies. You can also pay off the full balance first, wait for a clear title, and then list the car. That approach gives you clean paperwork but requires upfront cash and waiting several weeks.

Should you roll negative equity into a new loan?

Dealers sometimes offer to fold your negative equity into the loan for your next car. While it avoids writing a check today, it usually puts you deeper underwater on your new loan. You may also face a higher interest rate.

If possible, try to minimize the amount you roll over. Selling privately or choosing a lower-priced replacement vehicle can keep your debt manageable.

The main reasons vehicle owners end up underwater

• Small or no down payment
• Long-term loans (72–96 months)
• High interest rates
• Rapid early depreciation
• Rolling old debt into a new loan
• Overpaying for the car
• Buying a car with issues you are unaware of
• High mileage or condition drops
• Shifts in the used-car market

How to avoid negative equity

• Buy used or nearly new to let someone else absorb the initial depreciation
• Aim for a down payment (even modest is helpful)
• Choose a shorter loan term so you build equity faster
• Compare lenders aggressively—rates matter
• Avoid markups and unnecessary add-ons
• Get a pre-purchase inspection (PPI) from a trusted mechanic
• Pick vehicles with strong resale value
• Don’t roll old negative equity into a new loan
• Keep mileage and condition in check
