What is CPM

CPM stands for Cost Per Mille (mille is Latin for thousand). It represents the cost to reach 1,000 impressions of your advertisement.

An impression is counted each time your ad is displayed, regardless of whether someone clicks on it or not.

CPM is primarily used for:

  • Brand awareness campaigns
  • Display advertising
  • Video advertising
  • Social media advertising
  • Comparing costs across platforms

How to Calculate CPM

There are three formulas you can use depending on what you're trying to find:

Calculate CPM

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

Example: You spend $500 for 250,000 impressions

  • CPM = ($500 ÷ 250,000) × 1,000 = $2.00

Calculate Total Cost

Cost = (CPM × Impressions) ÷ 1,000

Example: CPM is $3.50 and you want 150,000 impressions

  • Cost = ($3.50 × 150,000) ÷ 1,000 = $525

Calculate Impressions

Impressions = (Cost × 1,000) ÷ CPM

Example: You have a $1,000 budget with a $4 CPM

  • Impressions = ($1,000 × 1,000) ÷ $4 = 250,000 impressions
