Many people choose to trade in a car when buying or leasing another car. But how does the trade-in process work? Do I lose money by trading?

Here is how a car trade works. Car dealers buy your old car from you and give you credit toward the price of a new car. The trade-in credit is like a down payment and reduces the price of your new car, making your monthly payments smaller. The dealer then puts your old car on his used-car lot to sell, or he sends it to a dealer car auction where another dealer will buy it to put on his own used-car lot.

Dealers make a lot of profit on selling used cars they’ve taken as trade-in. They pay the trading customer a low wholesale price, and sell the car for a higher retail price. That’s how they make their money and stay in business.
