CPM Calculator is a free browser tool for checking advertising cost and impression calculations. Enter any two of CPM, advertising spend and impressions to calculate the missing value. Related calculators cover CPC, CTR and eCPM conversions so users can compare the metrics used in media planning.
It is useful for checking an advertising budget, converting an impression target into estimated spend, or reviewing the arithmetic behind a campaign report. Results follow the numbers entered by the user; they are planning calculations rather than predictions of campaign performance or guaranteed advertising returns. No account is needed.
