CPM — cost per thousand impressions — is how display, social, and sponsorship inventory is priced and compared. This calculator derives CPM from any cost/impression pair, plus the inverse views: cost per single impression and impressions per $100.
Use it to compare placements on equal footing: a $500 newsletter sponsorship reaching 40,000 readers is a $12.50 CPM — instantly comparable with your paid social CPMs.
