Trade-In Equity Calculator
Thinking about trading in your car? Enter what it is worth and what you still owe to see your equity — and what the loan on your next car would cost.
Your trade-in and next loan
How it works
Trade-in equity is simple math: what your car is worth minus what you still owe on it. If the value is higher, you have positive equity — that amount works like a down payment on your next car. If the payoff is higher, you have negative equity, also called being upside down: you owe more than the car is worth.
Negative equity does not stop you from trading in, but it gets rolled into your new loan. That means you borrow more than the new car's price, start upside down on the new car too, and pay interest on the old car's leftover debt. It is one of the fastest ways to end up owing far more than a car is worth.
The best fix is usually time: keep paying the current loan while the balance falls, and wait until the value catches up with the payoff. If you must trade in while upside down, extra cash down shrinks the shortfall — and a shorter loan term keeps the cycle from repeating.
Frequently asked questions
What is trade-in equity?
It is the difference between what your car is worth and what you still owe on it. Positive equity means the car is worth more than the loan balance; negative equity means you owe more than it is worth.
What does it mean to be upside down on a car loan?
It means your loan balance is higher than the car's current value. It usually happens when a car loses value fast, the loan term is long, or the down payment was small — a new car typically loses roughly 15–20% of its value in the first year.
Can I trade in a car I still owe money on?
Yes. The dealer pays off your old loan as part of the deal. If you have positive equity, the extra goes toward your new car. If you are upside down, the shortfall is usually added to your new loan.
Will negative equity raise my monthly payment?
Yes — you are borrowing extra money to cover the old loan's shortfall, so the new loan is bigger and the payment is higher, even though the new car costs the same.
Should I sell privately instead of trading in?
A private sale usually brings a higher price than a trade-in, which can wipe out negative equity or add to positive equity. The trade-off is the time and hassle of listing the car, meeting buyers, and handling the payoff yourself.
How do I find my loan payoff amount?
Your lender can give you a payoff quote — the exact amount to close the loan on a given date, including interest accrued up to that day. It is usually a little higher than the balance shown on your monthly statement.
