Enter the assessed/appraised value ($) and the market value ($) into the Assessment Ratio Calculator. The calculator will evaluate and display the Assessment Ratio. 

Assessment Ratio Formula

The following formula is used to calculate the Assessment Ratio. 

ASR = AV / MV 

  • Where ASR is the Assessment Ratio ( )
  • AV is the assessed/appraised value ($) 
  • MV is the market value ($) 

How to Calculate Assessment Ratio?

The following example problems outline how to calculate Assessment Ratio.

Example Problem #1:

  1. First, determine the assessed/appraised value ($). 
    • The assessed/appraised value ($) is given as: 150,000.
  2. Next, determine the market value ($). 
    • The market value ($) is provided as: 160,000.
  3. Finally, calculate the Assessment Ratio using the equation above: 

ASR = AV / MV 

The values given above are inserted into the equation below and the solution is calculated:

ASR = 150,000 / 160,000  = .9375

Example Problem #2: 

For this problem, the variables required are provided below:

assessed/appraised value ($) = 140,000

market value ($) = 130,000

Test your knowledge using the equation and check your answer with the calculator above.
