What this tool does

A CPM (cost per thousand impressions) calculator divides your ad spend by the number of impressions, then scales it to a cost per 1,000 views — the standard way display and video campaigns are priced.

How it works

  1. Enter your total ad spend for the campaign.
  2. Enter the total number of impressions it received.
  3. The CPM updates instantly as you type.
Example: $150 in spend across 50,000 impressions works out to a CPM of $3.00 per 1,000 impressions.
