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

Frequently Asked Questions (FAQ)

What is the significance of calculating the Discrepancy Rate?

Calculating the Discrepancy Rate is important for understanding the proportion of errors or discrepancies within a set of data, such as ad impressions. This can help in assessing the quality of data and identifying areas for improvement in data collection or processing methods.

Can the Discrepancy Rate formula be used for any type of data?

Yes, the Discrepancy Rate formula (DR = D / I * 100) is versatile and can be applied to any dataset where you need to calculate the percentage of discrepancies or errors among total observations. However, the context and definitions of discrepancies might vary depending on the specific field of application.

How can discrepancies in impressions affect a digital marketing campaign?

Discrepancies in impressions can significantly affect a digital marketing campaign by providing inaccurate data on how many times an ad was actually viewed. This can lead to misinformed decisions, wasted budget, and ineffective targeting strategies, ultimately impacting the campaign’s return on investment (ROI).

Are there any tools available to help reduce discrepancies in impressions?

Yes, there are several tools and platforms available that can help minimize discrepancies in impressions. These include ad verification services, more sophisticated analytics platforms, and ad servers with advanced filtering capabilities to ensure accurate tracking and reporting of impressions.
