Enter the total discrepancy value and the expected value into the Calculator. The calculator will evaluate the Percent Discrepancy. 

Percent Discrepancy Formula

PD = D / EV * 100


  • PD is the Percent Discrepancy (%)
  • D is the total discrepancy value
  • EV is the expected value

To calculate Percent Discrepancy, divide the total discrepancy value by the expected value, then multiply by 100.

How to Calculate Percent Discrepancy?

The following steps outline how to calculate the Percent Discrepancy.

  1. First, determine the total discrepancy value. 
  2. Next, determine the expected value. 
  3. Next, gather the formula from above = PD = D / EV * 100.
  4. Finally, calculate the Percent Discrepancy.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total discrepancy value = 93

expected value = 1200
