Enter the total amount spent on the campaign or period.
Enter the total number of impressions generated by the campaign.
How This Calculator Works
This calculator divides total ad spend by total impressions and multiplies the result by 1,000 to estimate cost per thousand impressions. CPM helps measure how expensive it is to reach people with advertising.
Formula
CPM = (Total Ad Spend / Total Impressions) * 1000
Example
If you spend $2,000 on a campaign and generate 250,000 impressions, your CPM is $8.00. That means you paid $8 for every 1,000 impressions.
