 CPM (Cost Per Mille): The cost for every thousand impressions.
 Total Impressions: The total number of times the ad will be displayed or has been displayed.
 Total Cost: The total cost of the advertising campaign.
Based on the inputs, the calculator uses the formula:
$CPM=Total ImpressionsTotal Cost ×1000$
