Kelley Blue Book gives you a market value for your car based on its make, model, year, mileage, and condition

Kelley Blue Book (KBB) is a pricing guide owned by Cox Automotive that publishes estimated values for used and new vehicles. When you enter your car's details on their website or mobile app, the tool returns a range — typically labeled as "Fair Purchase Price," "Good Purchase Price," and sometimes "Excellent Purchase Price" — that reflects what similar cars are selling for in your area right now. The values change based on local market demand, so a 2019 Honda Civic in Denver may be worth more or less than the same car in rural Montana.

KBB does not determine what your car is actually worth. It shows you what dealers and private sellers have recently asked for similar vehicles. Your car's real value depends on its condition, service history, accident history, and whether a buyer wants it. But KBB gives you a starting point for negotiation, whether you are selling to a dealer, trading it in, or listing it privately.

Key Takeaways

  • Kelley Blue Book estimates your car's value by comparing it to recent sales of the same make, model, year, and mileage in your region.
  • You need your vehicle identification number (VIN), current mileage, and a description of the car's condition to get an accurate estimate.
  • KBB shows a range of values, not a single price, because condition and local demand affect what buyers will pay.
  • Dealer trade-in values are typically lower than private sale values on KBB, because dealers resell the car and need margin.
  • Your estimate can shift week to week as market conditions change, so check it again before you sell or trade.

How to look up your car on Kelley Blue Book

Go to kbb.com or open the Kelley Blue Book mobile app. On the home page, select "Find My Car's Value" or a similar button. You will be asked to enter your vehicle's year, make, and model. After you select those, KBB will ask for your car's mileage, body style (sedan, SUV, truck, etc.), and transmission type if there are options for that model.

Next, you describe your car's condition. KBB typically offers categories like "Excellent," "Good," "Fair," and "Poor." Be honest here — the estimate changes significantly based on which box you check. Excellent means the car looks and runs like new with no accidents or major repairs. Good means normal wear and tear, no accidents, and all systems working. Fair means visible wear, possibly a minor accident on record, or a repair or two. Poor means significant damage, multiple accidents, or major mechanical issues.

After you submit, KBB shows you a value range for your region. You can also enter your zip code to narrow the estimate to your local market. Some versions of the tool let you add details like recent repairs, new tires, or a clean title versus a salvage title, which can adjust the estimate up or down.

What the different value categories mean

Kelley Blue Book typically shows three or four price points. "Fair Purchase Price" is the lowest — it is what a dealer might offer you in a trade-in or what a private buyer might offer if they are negotiating hard. "Good Purchase Price" is the middle estimate and represents a typical sale between a private seller and buyer. "Excellent Purchase Price" or "Retail Price" is the highest and reflects what a dealer might ask when the car is on their lot, cleaned up and ready to sell.

The range between Fair and Excellent can be several thousand dollars. If you are selling to a dealer, expect an offer closer to Fair. If you are selling privately, you might list at Good or slightly above it and negotiate down. If you are buying from a dealer, the price tag will be closer to Excellent or Retail.

Trade-in value is usually lower than all of these because the dealer is buying your car to resell it. They need to account for reconditioning, lot time, and profit. KBB sometimes shows a separate trade-in estimate, which is worth checking if you are planning to trade your car toward a new purchase.

Why your KBB estimate might not match what you can actually sell for

Kelley Blue Book uses recent sales data and national trends, but it cannot know everything about your specific car. A car with a clean title and full service records may sell for more than KBB estimates. A car with a salvage title, frame damage, or a long list of accidents may sell for less. Mechanical problems that do not show up in a title search — a transmission that slips, a transmission that slips, or rust underneath — will lower the price a buyer will pay.

Local market conditions also matter. In a market where used cars are scarce, your car may be worth more than KBB shows. In a market flooded with similar vehicles, it may be worth less. Seasonal demand affects value too — pickup trucks are worth more in winter in snowy regions, and convertibles are worth more in spring and summer.

The condition rating you choose is also subjective. What you think is "Good" a buyer might see as "Fair." If you are selling privately, get a pre-purchase inspection from a mechanic so you can describe the car accurately and back up your asking price.

Using KBB to set a selling price

If you are selling your car privately, start by looking at the "Good Purchase Price" on KBB for your region. That is a reasonable asking price. You can list slightly above it knowing that buyers will negotiate, or you can list at that price if you want to move the car quickly. Check the listings on Craigslist, Facebook Marketplace, or Autotrader in your area to see what similar cars are actually listed for — that real-world data often matters more than KBB alone.

If you are trading your car to a dealer, get the KBB trade-in estimate before you walk onto the lot. Dealers will often offer less than KBB shows, so knowing the number gives you a baseline for negotiation. Bring a printout or screenshot of the KBB estimate with you.

When to check KBB again

Car values shift as market conditions change. During periods when used cars are in high demand, values rise. When supply is high, values fall. Check KBB again a week or two before you plan to sell, especially if several months have passed since your last check. If you are in the middle of negotiating with a buyer or dealer, a current estimate strengthens your position.

If your car has had an accident, major repair, or significant mileage added since your last check, the estimate will change. KBB updates its data regularly, so an estimate from six months ago may not reflect current market conditions in your area.

Other tools to cross-check your KBB value

Kelley Blue Book is one of several pricing guides. NADA Guides and Edmunds also publish used car values and sometimes show different numbers because they use different data sources and methodologies. If you are selling or trading, check at least two of these tools to see a range. If all three show similar numbers, you have more confidence in the estimate.

Real listings on Autotrader, Cars.com, and local classifieds are also valuable. Filter by your car's year, make, model, mileage, and condition, and look at what dealers and private sellers are actually asking. That real-world data often tells you more than any guide can.

Frequently Asked Questions

Do I need my VIN to get a KBB estimate?

No. You can get an estimate with just your car's year, make, model, mileage, and condition. A VIN is helpful if you want to check for accident history or verify details, but KBB's value tool does not require it. Some dealers or buyers may ask for your VIN to verify the car's history before making an offer.

Why is the KBB value so much higher than what dealers offered me?

Dealers offer trade-in value, which is lower than private sale value because they buy your car, recondition it, and resell it for profit. KBB's "Good Purchase Price" is closer to what a private buyer would pay. If you want more money, selling privately usually gets you closer to KBB's estimate than trading to a dealer.

Can I use KBB to dispute a dealer's trade-in offer?

You can use it as a reference point in negotiation, but dealers are not required to match KBB. Bring a screenshot of the estimate to the dealership and ask them to explain the difference. They may cite condition issues, mileage, or market factors you did not account for. If the gap is large, get a second opinion from another dealer or a mechanic.

How often does KBB update its values?

KBB updates its pricing data regularly, sometimes weekly or more often depending on market movement. Values can shift based on new sales data, seasonal demand, and broader economic conditions. Check again before you finalize a sale if more than a few weeks have passed since your last estimate.

What if my car has a salvage title or accident history?

KBB lets you note these details when you build your estimate, and the value will drop accordingly. A salvage title typically reduces value significantly because buyers worry about hidden damage and resale difficulty. An accident on record also lowers the estimate, though the impact depends on the severity and whether the car was repaired properly.
