Calculate how much you're spending per 1,000 impressions to reach your audience. This is a key metric for understanding ad campaign efficiency.
Learn how to use the Cost Per Thousand Impressions Calculator and its working principles
Cost Per Thousand Impressions (CPM) is a standard advertising measurement that represents the cost to reach 1,000 people with your ad. It's calculated by multiplying your total ad spend by 1,000 and then dividing by the total number of impressions.
A lower CPM indicates a more cost-effective campaign, while a higher CPM suggests your ads are more expensive per impression. Compare your CPM to industry benchmarks to assess campaign performance.
If you spent $500 on advertising and received 25,000 impressions, your CPM would be ($500 × 1000) / 25,000 = $20. This means it cost you $20 to reach 1,000 people with your ad.
