In advertising, CPM stands for cost per mille, which refers to the amount an advertiser pays a website per one thousand visitors who see its advertisements. This calculator can be used to find CPM, cost, or impressions using the following formulas:
CPM = (cost/impressions) * 1000
Cost = (impressions/1000) * CPM
Impressions = (cost/CPM) * 1000
To find CPM, cost, or impressions, simply fill in two of the three values below and then click the appropriate calculation button to find the missing value you’re interested in.
