How to calculate?

To calculate impressions based on CPM (Cost per Mille) and cost, you can use the following formula: Impressions = (Cost * 1000) / CPM

Here's a breakdown of the variables:

  • Impressions: This represents the total number of times your ad is displayed.
  • Cost: This is the total budget you're willing to spend on your advertising campaign.
  • CPM: This stands for Cost per Mille, which indicates the cost you pay to reach 1,000 viewers with your ad.


  1. Multiply Cost by 1000: This converts your cost from its unit (dollars, euros, etc.) to a value representing 1,000 impressions. Since CPM represents the cost per 1,000 impressions, we need both values in the same unit for comparison.
  2. Divide by CPM: This calculates the total number of impressions achievable with your budget considering the cost per 1,000 impressions.
