Definition – What is a CPM?

CPM, or Cost per Thousand, is a measurement of the cost of advertising on a marketing campaign.

Formula – How to calculate CPM

Per Impression Cost = Campaign Cost ÷ Impressions

CPM = Per Impression Cost x 1000

Example

A marketing campaign costs $500 and generates 3,000,000 impressions.

CPM = ($500 ÷ 3,000,000) x 1000 = 0.0001667 x 1000 = 0.17

Therefore, this marketing campaign has a CPM of $0.17.
