Cost Per Impression (CPM)

Cost Per Impression (CPM), or Cost Per Mille, is an advertising pricing model where advertisers pay for every 1,000 times their ad is displayed to users, regardless of whether the ad is clicked. CPM is commonly used for brand awareness campaigns and display advertising.

How to Calculate CPM

CPM = (Total Cost ÷ Total Impressions) × 1,000

Example Calculation

If you spent $500 for 100,000 impressions:

CPM = ($500 ÷ 100,000) × 1,000 = $5.00

This means you paid $5 for every 1,000 ad impressions.
