Whenbuying or selling a used car, many people rely on theKelley Blue Book (KBB), which has been around since 1926. One sign of its popularity: In 2017, over20 million unique visitors per month visited the Kelley Blue Book website, today the number is likely even higher.
Although automotive experts acknowledge that the Kelley Blue Book is one of the most popular and trusted guides in automotive pricing, the question remains: Is it accurate and reliable? Here’s a look at how Kelley determines car pricing, an assessment of some issues consumers might encounter with KBB pricing, and a brief review of some of the top competitors in the industry.
Key Takeaways
- The Kelley Blue Book—and its equally popular website—is one of the most trusted guides for automobile pricing, used by those who are buying or selling cars.
- Kelley assesses a wide array of different values to both used and new vehicles. For used vehicles some of them include: Trade-in value, typical listing price, fair purchasing price (CPO), and private party.
- Kelley determines Blue Book values by analyzing pricing information from real-world used car prices, as well as industry developments, economic conditions, and location.
- Potential problems with Blue Book values include a delay as price information is assessed, the consumer tendency to overrate the value of the car they are selling or trading in, and a mismatch between wholesale values listed by Kelley and the prices used by dealers, who access special industry-only pricing info.
How Kelley Blue Book Determines Car Values
Kelley Blue Book receives real-world used car prices from wholesale auctions, independent and franchised dealers, rental fleets, auto manufacturers, lessors, and private party transactions. Using this data, they make weekly updates to prices.
Kelley’s proprietary algorithm analyzes pricing data along with historical trends, current economic conditions, industry developments, time of year, and location to determine Kelley Blue Book values.
That process results in 12 different used car values, in addition to several new car values. Some of the most crucial used car values are:
- Private-party value: The starting point for a negotiation between a private buyer and seller for "as is" sales.
- Trade-in value: The amount you are likely to get from a dealer for a trade-in.
- Typical listing price: Represents what dealers are typically asking for the used car.
- Fair purchase price (CPO): The price consumers may reasonably expect to pay for a certified pre owned car of this year, make, and model.
Some Issues With KBB Pricing
Some factors that could affect the accuracy of KBB values are lag time, consumer bias, and mismatched data.
LagTime
It takes time for data and analysis to make its way through KBB. Prices listed may not always reflect the very latest trends and economic conditions.
Consumer Bias
Most people think the car they are selling or trading in is in better condition than it really is. If you misjudge the condition of a car for trade-in or purchase, your expectations may not match the reality of KBB’s valuation structure.
Mismatched Data
Most dealers do not use KBB for trade-in (wholesale) values. Instead, many rely on National Auto Research’s Black Bookor the Manheim Market Report, neither of which is available to the public. More important, both tend to skew lower than KBB in wholesale pricing.

Solutions for Consumers
If you use KBB as a general guide and follow the suggestions below,Kelley Blue Book data can be very useful.
Print out Definitions
If negotiating to buy a used car from a private seller, show KBB’s car condition definitions to the seller, especially if you believe the car is priced too high.
Negotiate
KBB’s pricing structure tends to favor dealers, meaning listed retail prices can be higher than other guides. Start with the listed retail price and bargain down.
Ask for Sources
Be aware that insider guides like Manheim or Black Book tend to show lower wholesale prices than KBB. Ask about the source of the trade-in offer or wholesale price.
Consult Other Guides
Consult one or more other websites or pricing guides to get an “average” for the vehicle you are trading in, selling, or planning to buy.
Since the three main consumer guides—KBB, Edmunds.com, and NADA with J.D. Power—use different algorithms, your best bet is to check all three and calculate an average price.
Additional Resources
The following are several sources you can check for pricing and rating information before buying, trading in, or selling a used car.
Edmunds: This websiteoffers an appraisal engine that includes five car condition categories compared with KBB’s four. This can be helpful—or generate confusion—depending on how realistic you are about your car’s condition. Many experts believe Edmunds' values are more accurate than KBB's. That’s not always the case, of course, which is why getting several estimates and averaging still makes the most sense.
NADA with J.D. Power: One of the oldest guides, NADA guides were designed for dealer members of the National Automobile Dealers Association (NADA) trade group. For consumers, NADA partners with J.D. Power. Their website will lead you to J.D. Power's site where you can research new and used vehicle values by make and body style.
Consumer Reports:The well-respected, noncommercial (no advertising accepted) publicationoffers lots of information if you buy an online subscription, less if you don’t. The website features general pricing on used cars, information on reliability, cars to avoid, and much more.
The Bottom Line
Kelley Blue Book is a very good resource, but it should not be the only one you consult. Although none of the top used car buying guides is perfect, when taken together—along with additional information gained from other websites and tools, such as auto loan calculators—they can provide reasonably reliable and accurate information for your used car transaction.
