Trading In a Car When You Owe More Than It Is Worth: How Negative Equity Works

Car ads often make trading in sound easy.

Bring in your old car, and the dealer promises to pay off your loan, no matter how much you owe.

For drivers who owe more than the car is worth, that promise deserves a closer look.

The gap between the loan and the car's value is called negative equity.

It does not disappear when you trade in the car.

This guide explains how negative equity works, how dealers handle it and how to protect yourself.

It draws on consumer guidance from the Federal Trade Commission.

What negative equity is

With rare exceptions, a car loses value as it gets older.

Accidents, repairs and other damage can push the value down even more.

A loan, on the other hand, shrinks slowly, especially in the early years.

So it is common to owe more on a car loan than the car would sell for.

The FTC guide to trade-ins and negative equity calls this situation negative equity.

Many people also call it being upside down on a loan.

Why it builds up

A few common choices make negative equity more likely.

  • A small down payment, so the loan starts close to the full price.
  • A long loan term, so each early payment pays off very little of the balance.
  • Extras added to the loan, such as service contracts or other add-ons.
  • Debt from an earlier car rolled into the current loan.

None of these is always wrong.

Together, they can leave you owing money on a car long after it has lost much of its value.

How a trade-in with negative equity works

The FTC uses a clear example.

Say your car is worth $15,000, but you still owe $18,000 on the loan.

You have $3,000 in negative equity.

To trade the car in, that $3,000 has to be paid by someone.

Some dealers promise to pay it off themselves.

In reality, they may pass the cost back to you.

They might add the $3,000 to your new car loan, take it out of your down payment, or both.

Now you have a bigger loan and pay interest on the old debt as well as the new car.

The FTC states that this is illegal when a dealer says it will pay off the old loan but rolls the cost into the new one.

How to spot rolled-over debt in the contract

Before you sign a financing contract, the dealer must give you disclosures about the cost of the credit.

Read them closely.

Look at two numbers in particular: the down payment and the amount financed.

Compare the amount financed with the agreed price of the new car, plus taxes and fees.

If the amount financed is higher than you expect, ask what was added.

Check whether your down payment shrank or vanished.

You may need to do a little math, but it is worth the effort.

Once you sign, the numbers are much harder to change.

Watch the total, not just the monthly payment

Many buyers focus on the monthly payment.

A dealer can lower that payment by stretching the loan over more months.

The payment looks smaller, but the total you pay can grow.

When negative equity is rolled in, a longer loan can hide it for years.

Always ask for the total of all payments and compare it across offers.

Find out what your car is worth first

Before you start negotiating, learn the value of your current car.

The FTC suggests checking pricing guides from the National Automobile Dealers Association, Edmunds and Kelley Blue Book.

Compare the trade-in value with your loan payoff amount.

Your lender can tell you the exact payoff figure.

If the payoff is higher than the value, you know you have negative equity and roughly how much.

Walking into the dealership with these numbers makes it harder for anyone to blur them.

Your options when you are upside down

The FTC lists several ways to deal with negative equity.

Wait if you can

Keeping your current car until you have positive equity is often the cheapest path.

You can speed that up with extra principal-only payments, if your loan allows them.

Ask your lender how to make sure extra money goes to the principal.

Sell the car yourself

A private sale may bring more money than a dealer offers for a trade-in.

That can shrink the gap or close it entirely.

You will still need to pay off the loan before the buyer can get the title.

Ask exactly how the dealer will handle it

If you still want to trade in, ask the dealer to explain how the negative equity will be handled.

Make sure any spoken promises are written into the contract.

Do not sign until you understand every term and what your monthly payment includes.

Keep the new loan as short as you can afford

If the old debt is rolled into the new loan, the loan term matters even more.

The FTC notes that a longer term means it takes longer to reach positive equity.

It also means you pay more interest overall.

Questions to ask before you sign

  • What is my trade-in value, in writing?
  • What is the payoff amount on my current loan?
  • Is any part of my old loan being added to the new one?
  • What is the amount financed, and what does it include?
  • What is the interest rate, and how many payments will I make?
  • Are any add-ons included, and can I remove them?

A trustworthy dealer should answer these questions clearly.

If the answers keep changing, slow down or walk away.

Avoid the cycle on your next car

Rolling negative equity from one car to the next can turn into a cycle.

Each new loan starts deeper underwater than the last one.

The FTC guide to financing or leasing a car recommends understanding the full cost and every term before you commit.

A larger down payment, a shorter loan and fewer extras all help.

So does choosing a car you plan to keep long enough to pay off.

If you are shopping for a used car,

the FTC guide to buying a used car from a dealer covers the other checks to make before you sign.

Report a problem

If a dealer misled you about paying off your old loan, report it.

The FTC accepts complaints about dealer advertising, sales and finance contracts at ReportFraud.ftc.gov.

You can also contact your state attorney general.

Your report helps officials spot patterns and protect other buyers.
