About This CPM Calculator
This free CPM Calculator helps advertisers, publishers, marketers and website owners calculate the cost of 1,000 advertising impressions.
What Does CPM Mean?
CPM stands for Cost Per Mille, where "mille" means one thousand. CPM represents the cost associated with 1,000 ad impressions.
CPM Formula
CPM is calculated by dividing the total advertising cost by the number of impressions and multiplying the result by 1,000.
CPM = (Total Cost ÷ Impressions) × 1,000
Example
If an advertising campaign costs $100 and receives 50,000 impressions, the CPM is $2.00.
Why Is CPM Important?
CPM helps advertisers compare advertising costs across campaigns, websites, platforms and advertising placements.
CPM Does Not Guarantee Performance
A lower CPM does not necessarily mean a campaign will perform better. Click-through rate, conversions, audience quality, targeting and other campaign metrics should also be considered.
