Enter the number of discrepancies in impressions, and your impression count into the Calculator. The calculator will evaluate the Discrepancy Rate. 

Discrepancy Rate Formula

DR = D / I * 100


  • DR is the Discrepancy Rate (%)
  • D is the number of discrepancies in impressions
  • I is your impression count

To calculate the Discrepancy Rate, divide the number of discrepancies by the impression count, then multiply 100.

How to Calculate Discrepancy Rate?

The following steps outline how to calculate the Discrepancy Rate.

  1. First, determine the number of discrepancies in impressions. 
  2. Next, determine your impression count. 
  3. Next, gather the formula from above = DR = D / I * 100.
  4. Finally, calculate the Discrepancy Rate.
  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.

number discrepancies in impressions = 500

your impression count = 8000
