What Is CPM?
CPM stands for Cost Per Mille, where “mille” means one thousand. In digital advertising, CPM represents the amount an advertiser pays for every 1,000 times an advertisement is displayed.
CPM is commonly used for display ads, social media advertising, video advertising, programmatic campaigns, website banners and brand-awareness campaigns. It helps marketers compare advertising costs across different platforms and audiences.
CPM Formula
To calculate CPM, divide the total campaign cost by the total number of impressions and multiply the result by 1,000.
CPM Calculation Example
Suppose an advertising campaign costs $500 and generates 100,000 impressions.
CPM = ($500 ÷ 100,000) × 1,000
CPM = $5.00
CPM = $5.00
This means the advertiser paid $5 for every 1,000 ad impressions.

Why Is CPM Important in Advertising?
CPM makes it easier to compare the cost of reaching audiences across different advertising channels. For example, you can compare the CPM of a Facebook campaign with a Google Display, YouTube, LinkedIn or website banner campaign.
A lower CPM generally means that you are receiving more impressions for your budget. However, the cheapest CPM is not always the best campaign. Audience relevance, ad quality, clicks, conversions and return on ad spend should also be considered.
CPM vs CPC
CPM charges advertisers based on impressions, while CPC charges advertisers when someone clicks the advertisement. CPM is usually suitable for awareness campaigns, while CPC can be useful when the main objective is generating website traffic.
CPM vs CPA
CPA stands for cost per acquisition or action. It measures how much you spend to generate a conversion, sale, registration or another desired action. CPM measures ad exposure, whereas CPA measures the cost of results.
What Is a Good CPM?
A good CPM depends on the advertising platform, industry, audience, location, campaign objective, competition and ad format. Instead of judging CPM alone, compare it with campaign reach, engagement, click-through rate, conversion rate and revenue.
Frequently Asked Questions

CPM means Cost Per Mille or cost per thousand impressions. It
shows how much an advertiser pays for every 1,000 times an
advertisement is displayed.
Divide the total advertising cost by the total impressions,
then multiply the result by 1,000. For example, a $500 campaign
with 100,000 impressions has a CPM of $5.
Divide the total impressions by 1,000 and multiply the result
by the CPM rate. For example, 200,000 impressions at a $4 CPM
would cost $800.
Divide the total campaign cost by the CPM rate and multiply
the result by 1,000. A $1,000 budget at a $5 CPM could generate
approximately 200,000 impressions.
Not always. A lower CPM provides cheaper exposure, but the
audience may be less relevant. Campaign quality should also be
evaluated through clicks, conversions, engagement and revenue.
