How to use eCPM
eCPM is calculated by dividing revenue by impressions, then multiplying the result by 1,000. Enter revenue and impressions. The calculator estimates effective revenue per 1,000 impressions.
Worked example
If 250,000 impressions generate $750 in revenue, eCPM is $3. This converts actual earnings into a common rate that can be compared across placements and formats.
Interpret the result
Compare eCPM only across equivalent reporting periods and impression definitions. Revenue can rise while eCPM falls when a large increase in lower-value impressions changes the traffic mix.
