Where to find your car's value
Your car's value depends on its age, mileage, condition, and local market demand — so the number changes based on where you look and when you check. The most widely used sources are Kelley Blue Book (kbb.com), NADA Guides (nadaguides.com), and Edmunds (edmunds.com). Each pulls from different data sets, so you may see different numbers from each site.
To get a value from any of these sites, you enter your vehicle's year, make, model, mileage, and condition (usually rated as poor, fair, good, or excellent). The site then shows you a range — typically a trade-in value (what a dealer would pay you) and a retail value (what you might sell it for privately). Trade-in values are almost always lower than retail values because dealers need room to resell the car.
If you are selling to a private buyer or trading in to a dealer, the retail value is more relevant. If you are buying and want to know whether the asking price is fair, compare it against the retail value for that condition level. If you are insuring the car or dealing with a total loss claim, your insurance company may use a different valuation tool — ask them which one they use.
Key Takeaways
- Kelley Blue Book, NADA Guides, and Edmunds are the three main free sources for car values, and they often show different numbers because they use different data.
- Trade-in value is what a dealer pays you; retail value is what a private buyer typically pays — retail is always higher.
- Your car's condition rating (poor, fair, good, excellent) has a large effect on the value, so be honest when you enter it.
- Local market conditions matter — the same car may be worth more in one region than another, so check the value for your specific area.
How condition affects the price you see
The condition you select on a valuation site can shift the value by hundreds or thousands of dollars. "Excellent" means the car looks and runs like it is nearly new, with no dents, stains, or mechanical issues. "Good" means normal wear — some minor scratches or scuffs, but nothing that affects how it drives. "Fair" means visible wear, maybe a dent or two, worn interior, or minor mechanical problems. "Poor" means significant damage, high mileage wear, or mechanical issues that need repair.
Be realistic about your car's condition. If you overstate it, the value you see will be too high, and you will be disappointed when you try to sell. If you understate it, you may miss out on a higher offer. Take photos of the interior and exterior in good light, and compare them to photos of cars listed at each condition level on the valuation site.
Why different sites show different values
Kelley Blue Book, NADA, and Edmunds each collect data from different sources — auctions, dealer sales, private sales, and market reports. They also weight recent sales differently and may adjust for regional demand. A car that is popular in one part of the country might be less desirable in another, so the same vehicle can have legitimately different values depending on where you are.
Rather than treating one number as "the" value, think of the range across all three sites as a realistic band. If Kelley says $8,500, NADA says $8,200, and Edmunds says $8,700, your car is probably worth somewhere in that $8,200 to $8,700 range. The wider the gap between sites, the more local factors or recent market shifts are affecting the price.
Checking your car's history before you value it
Before you check value, run a vehicle history report using Carfax (carfax.com) or AutoCheck (autocheck.com). These reports show accidents, title problems, service records, and mileage history. A car with a clean history is worth more than an identical car with accident damage or a salvage title, even if the damage was repaired.
If your report shows an accident, the valuation sites may not automatically account for it — you may need to lower the condition rating yourself or note it separately. If your title is branded (salvage, rebuilt, flood, lemon law), the value drops significantly, and some buyers will not consider the car at all. Knowing this before you value the car helps you set realistic expectations.
Using value estimates when you are buying
If you are looking at a used car for purchase, check its value on all three sites before you make an offer. Compare the asking price to the retail value for that condition level in your area. If the asking price is close to or below the retail value, it is likely a fair deal. If it is well above retail, the seller may be overpricing, or the car may be in better condition than you think — inspect it carefully or have a mechanic look at it.
Keep in mind that valuation sites show averages. A car with recent major repairs (new transmission, new engine) might be worth more than the average. A car with deferred maintenance (worn brakes, failing suspension) might be worth less. The sites cannot account for every individual car's history, so use the value as a starting point, not a final answer.
What happens when your car is worth less than you owe
If you financed your car and the loan balance is higher than the car's current value, you are "upside down" or "underwater" on the loan. This matters most if you want to sell or trade in the car before the loan is paid off. When you sell, you will owe the lender the difference out of pocket. When you trade in, some dealers will roll the negative equity into a new loan, but this costs you more in interest.
If you are in this situation, you have a few paths: keep the car and pay off the loan, pay down the loan balance faster to reduce the gap, or wait until the car's value rises or the loan balance falls enough that you break even. Checking your car's value regularly helps you track when you reach that point.
Frequently Asked Questions
Why do the three valuation sites show different numbers?
Each site pulls from different data sources — auctions, dealer sales, private sales — and weights recent sales differently. They also adjust for regional demand, which varies by location. The differences are usually within a few hundred dollars, but they can be wider if your car is unusual or if the market has shifted recently.
Should I use trade-in value or retail value when I am selling privately?
Use retail value. Trade-in value is what a dealer pays you, which is always lower because the dealer needs to resell the car and make a profit. When you sell to a private buyer, you can ask for the retail value or somewhere between retail and trade-in, depending on the car's condition and how quickly you need to sell.
Does mileage affect the value a lot?
Yes. The valuation sites ask for your exact mileage because it is one of the biggest factors in value. A car with 50,000 miles is worth significantly more than the same car with 150,000 miles. Make sure you enter your actual mileage, not an estimate.
What if my car has been in an accident?
Run a vehicle history report first to see if the accident is documented. If it is, lower your condition rating or note the accident when you enter your car's details. The valuation sites may not automatically adjust for accident history, so you may need to estimate the value reduction yourself — typically 10 to 30 percent depending on the severity.
Can I use these values to negotiate with a dealer?
Yes. Bring a printout or screenshot of the value from at least one of the three sites when you trade in or sell. Dealers know these sites exist and expect customers to have checked them. If the dealer's offer is significantly lower than the valuation, ask why — they may point out condition issues you missed, or they may be lowballing you.
