Looking to calculate your ad campaign’s cost-effectively? The CPM (Cost Per Thousand Impressions) metric is one of the most widely used pricing models in digital advertising. Whether you’re an advertiser, publisher, or marketer, understanding how to calculate CPM is essential to managing your ad budget and campaign performance.
At CPMInsider.com, we’ve created an easy-to-use CPM Calculator to help you instantly compute the cost of your advertising campaigns based on impressions and total spend.
💡 What is CPM?
CPM stands for “Cost Per Mille,” where Mille means thousand in Latin. It refers to the cost an advertiser pays for every 1,000 impressions their ad receives.
Formula to calculate CPM manually:
CPM = (Total Cost ÷ Total Impressions) × 1000
Example: If you spend $500 to serve 100,000 ad impressions:
CPM = (500 ÷ 100,000) × 1000 = $5.00
