A. How to calculate a NADA value using the NADA Official Used Car Guide

  • Look at the cover of your Guide to make sure you have the right region and the most current month. A break down of each region is listed on the inside back cover.
  • Identify the correct model year, make and body style of the vehicle to be valued, as well as current mileage and any options.
  • Look up the page number of the make in the table of contents, turn to that page.
  • Locate the vehicle to be valued based on all available information: year, body style, engine size, manufacture's model number, VIN, etc.
  • The NADA base value is published next to the body type description, the choices are Trade-in (Rough, Average, Clean), Clean Loan and Clean Retail.
  • Select the appropriate NADA base value as your starting point.
  • The NADA base value may need to be adjusted for mileage. The adjustment applies to the NADA base value, so make mileage adjustments before adding options.
  • Now, select the option(s) that apply and add/deduct the corresponding figures to appropriate values (trade-in, loan, retail +/- mileage adjustment). For additional truck options, to refer to the Truck Options page for additional options not included under each vehicle.
  • Note that not all options listed under each vehicle group are applicable to all the body styles. The body styles for which an option is standard will be shown in parentheses denoted by "Std.", or with an asterisk footnote. Do not add these option values. However, certain options are only available on certain body styles. Where applicable, the body style will be listed in parentheses after the option, without the Std. Designation. You need to add these values.
  • Again, remember that any reconditioning adjustment is your call based on experience. The value you just calculated is for a clean vehicle.

The NADA Official Used Car Guide® is an appraisal reference tool and not a price list.


Q. How can I identify the model year of a vehicle?
(Back to top)

A. Vehicle Identification Numbers (VINs)

In 1981 the National Highway Traffic Safety Administration and the Department of Transportation required all manufacturers selling motor vehicles in the United States to use a standardized 17-character Vehicle Identification Number (VIN). This standard establishes a format that makes exact vehicle identification easy. Prior to 1981, numerous VIN formats were used which made vehicle identification difficult.

VIN's are printed on a small metal plate usually located on the left side of the dashboard visible through the windshield. Some models and makes place the VIN plate on the inside of the left windshield pillar.

The 10th digit of the VIN indicates the model year. This will be true on all vehicles since 1981. Please refer to the following chart for model year indicator codes.

Q. What values are included in the NADA Official Used Car Guide®? (Back to top)

A. We have three Trade-in values (Rough, Average, Clean), Clean Loan and Clean Retail,

Trade-In - NADA’s estimated Trade-In value for a vehicle in rough, average or clean condition (see vehicle condition definitions) and mileage falling within NADA’s assumed mileage range.

Clean Loan - NADA’s suggested amount of credit that may be obtained on a vehicle based on the Clean Trade-In value. Providers of vehicle financing determine the amount of credit they are willing to extend on a vehicle.

Clean Retail - NADA’s estimated Clean Retail value for a vehicle in clean condition and mileage falling within NADA’s assumed mileage range.


Q. What values aren't included in the NADA Official Used Car Guide and why? (Back to top)

A. . Auction values are not included in the printed guidebook due to the frequency of their updates. Updated weekly, auction values are available electronically in NADA Online, NADA e-Valuator, NADA e-Valualtor for Dealers and Web Service.


Q. Should I add for a certain option or is it standard?
(Back to top)

A. Car option explanations

  • Options are considered standard on a vehicle if that vehicle is listed in parentheses following "Std.":
    e.g.- "Add Power Seat (Std. Accord V6)"

    In this case, the option value would not be added to those vehicles following "Std."

  • Option values may be added to the base NADA value if that vehicle is listed in parentheses:
    e.g.- "Add 7/8 Passenger Seating (Base Caravan)"
  • Truck option explanation
  • In order to determine the NADA value for truck option packages, users should add for the trim level and then add for any additional options listed with that vehicle.
    e.g.- The NADA value of a 1997 GMC Yukon 4D SLT would be determined by adding the trim and option values to the base value of the vehicle:
    "Add SLT Trim 4D" "Add Compact Disc Player" "Add Leather Seats"
    In this case, the option value may be added ONLY to vehicles listed in parentheses.
  • Option values should NOT be deducted from base NADA value if that vehicle is listed in parentheses following "Ex.":
    e.g.- "Deduct W/out Automatic Transmission (Ex. M3 Coupe, 540i)"

    In this case, the option value may be deducted from any vehicle EXCEPT those vehicles following "Ex."


Q. How do I calculate NADA values for Light-Duty Trucks?
(Back to top)

A. To determine the NADA value for four particular types of Light-Duty Trucks (please see table below), users will no longer have to add for trim level and/or drive type, as these adjustments will be addressed at the vehicle level. This significant enhancement is effective as of the January 2008 edition of the NADA Official Used Car Guide.

Make/Model Model Year Trim Package
Chevrolet Silverado 2001 - 2008 LS, LT, LTZ, Z71
Dodge Ram 2001 - 2008 SLT, Sport, Laramie, TRX4, SLT Plus
Ford F-Series 2001 - 2008 XLT, Lariat, King Ranch, Harley Davidson, Amarillo
GMC Sierra 2001 - 2008 SLE, SLT
