Calculate the cost per thousand impressions (CPM) for advertising campaigns, marketing efforts, or media buys.
Learn how to use the Cost Per Thousand Calculator calculator and its working principles
Cost Per Thousand (CPM) is a standard metric used in advertising to measure the cost of 1,000 impressions of an ad. It is calculated by dividing the total cost by the number of impressions and then multiplying by 1,000.
CPM is particularly useful for comparing the cost-effectiveness of different advertising platforms and campaigns. It helps you understand how much you're spending to reach 1,000 people, which is essential for budgeting and evaluating the efficiency of your marketing spend.
For example, if you spent $500 on an ad campaign that received 25,000 impressions, your CPM would be:
$500 / 25,000 impressions = $0.02 per impression
$0.02 per impression × 1,000 = $20 CPM
