What the NADA Guides are and why dealers use them

The NADA Guides are pricing books that show what used cars are worth in your area. NADA stands for National Automobile Dealers Association, and their guides are one of the three main sources dealers, lenders, and insurance companies use to set prices. When a dealer prices a trade-in, when a bank decides how much to lend you for a car loan, or when an insurance company calculates what to pay after an accident, they often look at NADA values.

The guides exist because used car prices vary by region, condition, mileage, and options. A 2019 Honda Civic worth $16,000 in rural Montana might be worth $17,500 in a city where demand is higher. NADA collects pricing data from auctions, dealer sales, and private sales across the country, then publishes values broken down by location, vehicle type, and condition. You can look up your own car's value to understand what it should cost, what a dealer should offer you in trade, or whether an insurance settlement is fair.

Key Takeaways

  • NADA publishes used car values online and in print, organized by region, model year, mileage, and condition level.
  • The guides show a range — a "loan value" (what a bank might lend), a "retail value" (what a dealer might charge), and a "trade-in value" (what a dealer might offer you).
  • Your actual car's value depends on its specific condition, mileage, accident history, and local demand, so NADA values are a starting point, not a final price.
  • You can access NADA values free online at nadaguides.com, or buy the print edition if you prefer a physical book.

The three values NADA shows for every car

When you look up a car in the NADA Guides, you see three different prices. Understanding what each one means helps you know whether you are getting a fair deal.

Trade-in value is what a dealer will offer you if you trade in your car toward a new purchase. This is the lowest of the three numbers because the dealer needs room to resell the car and cover their costs. If NADA shows a trade-in value of $12,000, expect a dealer to offer somewhere in that range, though they may offer less if the car has damage or higher mileage than the guide assumes.

Loan value (sometimes called "average loan value") is what a bank will typically lend you against the car. It sits between trade-in and retail. Banks use this figure because they need to protect themselves — if you default and they repossess the car, they want to be able to sell it quickly for at least what they lent you. If you are financing a used car purchase, the lender will often check NADA to make sure the loan amount does not exceed the loan value.

Retail value is the highest number, and it is what a dealer will charge a customer buying the car on the lot. This is the price you would see on a dealer's website or window sticker. Retail value assumes the car is in good condition and ready to sell when ready.

How condition and mileage change the price

NADA values are not one-size-fits-all. The guides break down prices by condition level, and mileage adjustments explore on top of that. When you look up your car, you choose a condition category that matches what you see.

Condition levels typically run from "excellent" (very low mileage, no accidents, interior and exterior like new) down to "poor" (high mileage, visible damage, mechanical issues). Each step down lowers the value. A car in excellent condition might be worth $2,000 to $3,000 more than the same model in good condition. The guides also adjust for mileage — a car with 80,000 miles is worth less than one with 60,000 miles, and NADA calculates that difference based on typical depreciation patterns.

This is why two identical model years and makes can have very different values. If you are selling your car, be honest about its condition when you look it up. If you are buying, use NADA to check whether the seller's price matches the condition they claim.

Where to find NADA values online and in print

NADA publishes values online at nadaguides.com, where you can search for free. The website lets you enter the vehicle year, make, model, mileage, and condition, then shows you values for your region. You can also narrow the search by adding options — leather seats, sunroof, all-wheel drive — because these affect price.

If you prefer a physical book, NADA publishes print guides four times a year (spring, summer, fall, winter). You can buy them at bookstores, online retailers, or directly from NADA. The print guides are useful if you are a dealer or lender who needs to reference values regularly, but most people find the online version faster and more current.

Two other major pricing guides exist: Kelley Blue Book (kbb.com) and Black Book (used mainly by dealers and lenders). All three use similar data sources, so values are usually close, but they can differ by a few hundred dollars depending on their regional data and adjustment methods. If you are negotiating a price, it is worth checking all three.

How to use NADA values when buying or selling

If you are selling your car privately, look up the retail value and price slightly below it. Buyers expect to negotiate, and pricing a few hundred dollars below NADA retail gives you room to come down while still hitting your target. If a dealer offers you a trade-in, compare their offer to the NADA trade-in value — if they are offering significantly less, ask why, or get a second opinion from another dealer.

If you are buying a used car from a dealer, check the NADA retail value before you walk onto the lot. If the dealer's price is well above retail for that condition and mileage, you know the car is overpriced. If you are financing, ask the lender what value they are using — if they are lending more than the NADA loan value, that is a red flag that the car may be overpriced or that the loan terms are risky.

If you are buying from a private seller, NADA values still matter, but private sales often run lower than dealer retail because there is no warranty and no dealer overhead. Use NADA as a ceiling, not a floor — a private seller might reasonably ask for 80 to 90 percent of retail value, depending on condition and local demand.

Why NADA values are a starting point, not a final answer

NADA values are based on averages and regional trends, but your specific car may be worth more or less. A car with a clean title and full service history is worth more than one with a salvage title or unknown maintenance. A car that was in an accident, even if repaired, is worth less than one with no accident history. Local demand matters too — a four-wheel-drive truck is worth more in Colorado than in Florida.

Insurance companies sometimes use NADA values to calculate payouts after an accident, but they may also adjust for your car's specific condition, mileage, and history. If you think an insurance settlement is too low, you can dispute it and provide evidence — photos, service records, or a mechanic's inspection — that your car was in better condition than the NADA value assumes.

Use NADA as your starting point for any negotiation, but do not treat it as gospel. It is one tool among several, and the final price always depends on what a buyer is willing to pay and what a seller is willing to accept.

Frequently Asked Questions

Does NADA value include the cost of repairs my car needs?

No. NADA values assume the car is in the condition you select — if you say "good," it assumes normal wear and tear, not major repairs. If your car needs a new transmission or engine work, that cost comes out of the value. A mechanic's inspection report showing needed repairs will lower what a dealer or private buyer will offer.

What if NADA shows a very different value than Kelley Blue Book?

Small differences (a few hundred dollars) are normal because the guides use slightly different data sources and regional adjustments. If the difference is large, check that you entered the same mileage, condition, and options in both. If you are still seeing a big gap, use the lower value as your negotiating baseline — it is safer to assume the car is worth less than to overpay.

Can I use NADA values to dispute an insurance company's settlement?

Yes. If your insurance company's offer is lower than NADA values for your car's condition and mileage, you can request a review and provide the NADA printout as evidence. Insurance companies do not always use NADA — some use their own databases — but NADA is widely recognized and can support your case if the settlement seems unfair.

Does NADA account for recalls or safety issues?

No. NADA values do not adjust for recalls or known safety problems. If a model year has a major recall, the actual market value may be lower than NADA shows. Research your specific car's recall history on the NHTSA website before you buy, and factor in the cost of repairs if recalls have not been addressed.

How often do NADA values update?

NADA updates values quarterly (four times a year) in the print guides. The online version updates more frequently as new market data comes in. If you are looking up a car's value, the online version will be more current than a print guide that is several months old.
