What Edmunds and Kelley Blue Book do
Edmunds and Kelley Blue Book (KBB) are websites that estimate what a used car is worth based on its make, model, year, mileage, and condition. You enter your car's details, and each site shows you a price range — typically a low estimate, an average, and a high estimate. Dealers, private sellers, and buyers use these estimates to decide whether a price is fair.
The two sites use different data sources and methods, so their estimates often differ by a few hundred dollars. Neither one sets the actual price of your car — that depends on what a buyer will pay and what a seller will accept. But both give you a starting point so you are not guessing in the dark.
Key Takeaways
- Edmunds and Kelley Blue Book both estimate used car value, but they use different data and may show different prices for the same vehicle.
- Both sites ask for the car's year, make, model, mileage, condition, and features — the more details you provide, the more accurate the estimate.
- These estimates are free to look up and do not require you to enter personal information or contact a dealer.
- The actual price you can get depends on local demand, the car's history, and whether you are selling to a dealer or a private buyer.
- Checking both sites and comparing their ranges gives you a more complete picture than relying on one alone.
How to look up a car's value on Edmunds
Go to edmunds.com and select "Find a Used Car" or "What's My Car Worth." Enter the car's year, make, and model. The site will ask whether you are looking at a car to buy or pricing one you own. If you are selling, choose "Sell Your Car."
Next, provide the mileage, condition (excellent, good, fair, or poor), and any major features or damage. Edmunds will show you a price range and break down what factors pushed the estimate up or down. You can also see what similar cars are listed for in your area, which shows you what dealers are actually asking.
How to look up a car's value on Kelley Blue Book
Go to kbb.com and select "Find a Car's Value" or "Sell Your Car." Enter the year, make, and model. KBB will ask for the mileage, condition, and interior and exterior features.
KBB shows you a "Kelley Blue Book Value" — their main estimate — plus what you might get if you trade it to a dealer versus selling it privately. The private-party value is usually higher because the buyer is not a business trying to resell it. KBB also shows listings from dealers in your area so you can see what similar cars are priced at right now.
Why the two sites give different numbers
Edmunds and Kelley Blue Book pull data from different sources. KBB uses transaction data from auctions and dealer sales. Edmunds uses pricing from dealers and private listings. They also weight recent sales differently and adjust for regional demand in different ways.
A car worth $15,000 on one site might be $15,300 on the other. This is normal. If the difference is larger — say, $1,000 or more — double-check that you entered the same details on both sites. A difference in mileage or condition can shift the estimate significantly.
What affects the price estimate
Both sites adjust the estimate based on mileage, condition, and features. A car with a clean title is worth more than one with a salvage or rebuilt title. A car with recent major repairs or accidents is worth less. Luxury features like leather seats or a sunroof add value; missing features or worn-out parts subtract it.
The estimate also depends on local demand. A truck may be worth more in a rural area than in a city. A convertible may be worth more in a warm climate. Both sites try to account for this, but the estimate is still a range, not a may provide.
How to use these estimates when buying or selling
If you are buying, use the estimate as a ceiling. A private seller asking $16,000 for a car KBB values at $15,000 is asking above market. You have room to negotiate. A dealer asking $16,000 for the same car is also above the estimate, but dealers typically price higher because they have overhead and warranty costs.
If you are selling to a dealer, expect to get less than the private-party value — dealers need to resell the car for a profit. If you are selling privately, aim for the middle of the range or slightly below to attract buyers quickly. Pricing too high means your car sits; pricing too low means you leave money on the table.
Check both sites and look at actual listings in your area. If five similar cars are listed at $15,200, $15,400, and $15,600, the estimates are probably close to reality. If listings are scattered between $14,000 and $17,000, the market is less clear, and you may need to price more carefully or wait for the right buyer.
What these estimates do not tell you
The estimate assumes the car is in the condition you reported. If you say "good" but the transmission is slipping, the actual value is lower. The estimate does not account for a car's full history — only major accidents and title issues. A car that was well-maintained but has no service records may be worth less than the estimate suggests.
The estimate also does not include taxes, registration, or dealer fees. If you are buying from a dealer, the final cost will be higher than the KBB value. If you are selling privately, you keep the full amount, but you may spend time showing the car and handling paperwork yourself.
Frequently Asked Questions
Do I have to give my contact information to see a car's value?
No. Both Edmunds and Kelley Blue Book show estimates without requiring you to enter your name, email, or phone number. You can look up as many cars as you want without being contacted by dealers or salespeople.
Which site is more accurate, Edmunds or Kelley Blue Book?
Neither is consistently more accurate — they use different data and methods, so each is accurate for different reasons. Checking both and comparing their ranges gives you a better sense of the true value than trusting one alone. The actual price depends on local buyers and sellers, not on either website's estimate.
Can I use these estimates to negotiate with a dealer?
Yes. Print or screenshot the estimate and bring it to the dealer. Dealers know these sites exist and expect customers to have looked them up. A dealer may still price above the estimate, but you have a factual reference point for negotiation.
What if the estimate seems way too high or too low?
Check that you entered the mileage and condition correctly — small changes in these fields shift the estimate. Look at actual listings for the same car in your area; if they match the estimate, the estimate is probably right. If listings are consistently higher or lower, the market in your region may differ from the national average the sites use.
Do dealers have to accept these estimates as the trade-in value?
No. Dealers set their own trade-in offers based on what they think they can resell the car for, their overhead, and their profit margin. The estimate is a reference point, not a binding offer. You can use it to decide whether a dealer's trade-in offer is fair, but the dealer is not required to match it.
