Free cost per impression calculator: CPI (cost per single impression) and CPM from ad spend and impressions, optional CPC and CTR, animated CPM sensitivity charts when impressions or spend shift, click vs non-click mix bar, scenario table—align CPI CPM math with Meta, Google Display, TikTok, and programmatic exports.
Definitions matter: This cost per impression calculator divides reported spend by reported impressions from your export. Platforms disagree on gross vs viewable, deduplication, and fee placement—always reconcile to the same column headers your finance team signs off on.
Summary: Enter total cost and impressions to get CPI (cost per single impression) and CPM (cost per thousand impressions). Add optional clicks for CPC, CTR, and a click vs non-click impression strip. Charts stress-test CPM when impressions or spend move—ideal before you defend a digital ad cost per impression slide in a weekly review.
