What is an eCPM calculator?
An eCPM calculator turns ad revenue and impressions into effective cost per mille β the revenue you earn for every 1,000 ad impressions served. Because it normalizes earnings to a per-thousand rate, eCPM is the standard yardstick for comparing ad monetization across networks, ad formats, placements and geographies, no matter how many impressions each one delivers. The formula is simple: divide total ad revenue by impressions, then multiply by 1,000.
eCPM is more useful than raw revenue because it strips out volume: a placement earning $500 from 200,000 impressions has a $2.50 eCPM, and you can line that up directly against any other source running at a different scale. This tool also shows revenue per million impressions so you can plan monetization at volume β and once you are optimizing what your ad revenue depends on, higher install conversion from better App Store creative compounds every impression you buy.
