Calculate CPM

CPM Formula

CPM = campaign cost divided by impressions, multiplied by 1,000. For example, a $500 campaign with 100,000 impressions has a $5 CPM.

Use CPM for ad buying and sponsorship pricing. Use the RPM calculator when you know revenue and pageviews and want to measure publisher yield.
