Trade-In Value Estimator
What is your car worth today? This free estimator applies a realistic depreciation curve, plus mileage and condition adjustments, to your original purchase price to estimate its current trade-in value. See the dollar value, the total depreciation so far, and how each factor moves the number before you talk to a dealer.
Estimate your car's trade-in value
Enter what you paid, how old the car is, your typical annual mileage and its honest condition. The tool applies a first-year drop of about 20 percent and roughly 12 percent per year after that, then adjusts for mileage and condition to estimate today's trade-in value.
This is an estimate of trade-in value, which is typically lower than a private-sale price. Dealers offer wholesale-leaning numbers because they need to recondition and resell at a profit. Treat the result as a baseline to negotiate from, not a guaranteed offer.
How the estimate works
The math follows the well-documented shape of automobile depreciation. A new car loses roughly a fifth of its value the moment it leaves the lot and through the first year, then sheds around 12 percent of its remaining value each subsequent year. By year five, a typical car is worth only about 40 percent of its original price. The deep dive on why this happens, and which cars hold value best, is in our car depreciation explained guide.
On top of the age curve, the tool adjusts for two things dealers scrutinize: mileage relative to a 12,000-mile-a-year norm, and condition. Driving well above average mileage pulls the value down; below-average mileage lifts it. Condition is a multiplier, because a clean, well-kept car in excellent shape genuinely commands more than the same car rated rough.
Trade-in versus private sale
Trade-in is the convenient path, not the lucrative one. A private sale almost always returns more money because you capture the margin a dealer would otherwise keep. The trade-off is effort: listing, fielding buyers, and handling paperwork. Our complete walkthrough on how to sell a used car covers pricing, presentation and safety for the private route, so you can weigh the extra cash against the extra work.

The trade-in tax advantage
There is one financial wrinkle that often makes trade-in more competitive than it first appears. In many U.S. states, when you trade a car in toward a new purchase, you pay sales tax only on the difference between the new car's price and your trade-in value, not the full price. On a meaningful trade-in and a typical tax rate, that saving can total several hundred to over a thousand dollars, narrowing or even erasing the gap between a trade-in and a private sale. Check whether your state offers this credit before deciding.
What this estimate cannot see
A simple curve captures the big forces, but real trade-in offers also reflect details no calculator knows. Make and model matter enormously: some brands and body styles hold value far better than the average because of demand, reliability reputation and limited supply, while others fall faster. Color, options and trim swing the number too, as do regional preferences, a four-wheel-drive truck is worth more in snow country than in a warm coastal city. Accident history reported on a vehicle history record, even after a clean repair, drags value down, and a salvage or rebuilt title cuts it sharply.
Current market conditions add another layer. When new-car supply is tight, used values rise across the board; when interest rates climb and demand cools, they soften. This is why two dealers can quote different numbers on the same car in the same week. Use this estimate as your anchor, then gather at least one or two real written offers, from a dealer and from an online instant-offer service, to see where your specific car lands against the curve.
Use the number wisely
Walk into the dealership knowing your estimated value, your car's documented service history, and a private-sale comparison. Dealers expect a negotiation, and an informed seller who can cite realistic figures gets a fairer offer. If the trade-in number lands far below this estimate without a clear reason, that is your cue to get a second quote or list it privately instead.
Frequently asked questions
How is trade-in value calculated?
This estimator starts from your purchase price and applies a depreciation curve of about 20 percent in the first year and roughly 12 percent per year after, leaving a typical car at around 40 percent of value by year five. It then adjusts for mileage relative to a 12,000-mile-a-year norm and for condition. Dealers use similar logic plus their reconditioning costs and resale margin.
Is trade-in value lower than private sale value?
Yes, almost always. A dealer offers a wholesale-leaning number because they must recondition the car and resell it at a profit, so a private sale typically nets more money. The trade-off is convenience and speed. In many states, though, a trade-in reduces the sales tax on your next car, a credit that can narrow the gap between the two options.
Does mileage really affect my car's value that much?
Yes. Mileage is one of the first things a dealer or buyer checks, because it signals remaining life and upcoming wear-item costs. Driving well above the roughly 12,000-mile-a-year norm pulls value down, while below-average mileage lifts it. The estimator reflects this with a mileage adjustment, capped so it does not swing the figure unrealistically far in either direction.
What is the trade-in tax advantage?
In many U.S. states, trading a car in toward a new purchase means you pay sales tax only on the price difference, not the full price of the new car. Depending on your trade-in value and local tax rate, that can save several hundred to over a thousand dollars. It can make a trade-in competitive with a private sale, so check your state's rules first.
