FAQs

CPM stands for “cost per mille,” and “mille” is the latin word for “thousand” so CPM is commonly referred to as “cost per thousand.” CPM is a marketing term that measures the cost per thousand impressions, and it is the rate that you’ll be charged for a set of one thousand views of your advertisement.

For example, if you spent $100 on a Facebook ad and it got 15,000 impressions, the CPM would be $10.00, which is the price you paid for 1,000 Facebook impressions.


It’s very simple to calculate CPM. Shopify’s free CPM calculator does it for you, but you can also use the following formula:

X (campaign cost) / Y (ad impressions) = Z (result) x 1000 = $ CPM


When you are doing an ad campaign or making an ad budget, estimating and measuring the CPM of a campaign is important to understand its effectiveness across different media channels. The media channel with the lowest CPM is often more effective because it requires less cost to reach 1,000 audience members.
