eCPM formula

eCPM=Total Earnings/Total Impressions×1000

Understanding the eCPM result

The ideal eCPM will vary according to your targets, ad type, and industry

• A high eCPM indicates that your ad placements are generating significant revenue per thousand impressions. This suggests effective targeting, ad formats, or high-quality content that engages viewers.
• A low eCPM indicates that you are generating less revenue per ad and need to optimize your ad placement, targeting, or content strategies.

When to calculate eCPM

eCPM should be calculated in the following situations:

• While comparing ad performance with various placements or on different platforms
• While reviewing your ad monetization strategies
• While evaluating the effectiveness of various ad formats
• Before setting benchmarks for future ad performance goals
• To assess the impact of seasonal trends on ad revenue

How to calculate eCPM with example

Imagine that your website earned $5,000 in ad revenue from 1,000,000 impressions. You can calculate eCPM as follows:

eCPM=Total Earnings​/Total Impressions×1000

eCPM = ($5,000/1,000,000)×1000 = $5

In this example, your eCPM is $5. This indicates that you earned $5 for every 1,000 ad impressions
