Publisher-side only Gross vs net eCPM Reverse-solve revenue or impressions

eCPM Calculator

Model publisher-side ad yield from gross revenue, monetized impressions, revenue-share drag, and fixed serving cost. Reverse-solve the gross revenue or impressions needed to hit a target net eCPM without drifting into advertiser CPM math.

CPM is what advertisers pay per 1,000 impressions. eCPM is what publishers earn per 1,000 monetized impressions. This page keeps both the headline and the math anchored on publisher monetization yield.

Inputs

Revenue before network share, mediation fee, or fixed serving cost.
Keep this to monetized impressions, not total pageviews or ad requests.
Reverse-solve the revenue or impressions needed to reach this publisher-side yield.
Examples: USD, KRW, $, credits.
  • Gross eCPM = gross revenue ÷ impressions × 1,000.
  • Net revenue = gross revenue × (1 - share rate) - fixed cost.
  • Net eCPM = net revenue ÷ impressions × 1,000.
Current view shows both gross and net eCPM, then compares current net yield against the target.
Current net eCPM is below target. Increase revenue, reduce fee drag, or cut fixed serving cost.

CPM vs eCPM

CPM is advertiser cost per 1,000 impressions. It answers what a buyer pays for inventory.

eCPM is publisher revenue per 1,000 monetized impressions. It answers what your inventory actually earns after blending sources. Net eCPM goes one step further and subtracts revenue share, mediation fees, and fixed serving costs.

  • Use CPM to compare media-buying prices.
  • Use gross eCPM to normalize top-line monetization yield.
  • Use net eCPM to plan take-home yield and partner economics.
