How to calculate?

Formula: CPM = (Cost / Impressions) * 1000


  • CPM: This represents the cost you incur to reach 1,000 viewers with your ad. It's a standard metric used for comparing advertising costs across different platforms.
  • Cost: This refers to the total budget you spend on your advertising campaign.
  • Impressions: This signifies the total number of times your ad is displayed, regardless of clicks or interactions.
  • 1000: Since CPM represents cost per thousand impressions, we multiply by 1000 to ensure the result is in that unit.

For example:

  • Let's say your campaign cost was $100 and you received 25,000 impressions.
  • Using the formula: CPM = ($100 / 25,000) * 1000 = $4

Interpretation: In this example, your CPM is $4, meaning it cost you $4 to reach 1,000 viewers with your ad campaign.
