What Is CPM? Cost Per Mille Explained + CPM Rates & Examples (Complete 2026 Guide)
CPM (Cost Per Mille) is one of the most important advertising metrics used to measure the value of ad impressions. If you run a website, blog, YouTube channel, or monetize traffic through platforms like Google AdSense or programmatic ad networks, understanding what CPM means is essential for evaluating traffic quality and maximizing revenue.
In this guide, you’ll learn exactly what CPM is, how it’s calculated, what affects CPM rates, and how publishers improve their earnings using CPM-based advertising in 2026.
What IS CPM Mean in Advertising?
CPM stands for Cost Per Mille, where mille means one thousand.
It represents the amount advertisers pay for 1,000 ad impressions.
An impression is counted every time an ad is displayed on a user’s screen, regardless of whether the user clicks on it. Because of this, CPM is considered an impression-based pricing model, making it ideal for brand awareness and reach-focused campaigns.
According to official Google Ads documentation, CPM is commonly used when advertisers want to maximize exposure rather than direct clicks or conversions.

CPM Formula (With a Simple Example)
CPM Formula
CPM = (Total Ad Cost ÷ Total Impressions) × 1,000
Example
If an advertiser spends $60 and receives 30,000 impressions:
CPM = (60 ÷ 30,000) × 1,000 = $2.00
This means the advertiser pays $2 for every 1,000 impressions.
CPM vs RPM vs CPC (Clear Comparison)
| Metric | Meaning | Who Uses It | What It Measures |
|---|---|---|---|
| CPM | Cost per 1,000 impressions | Advertisers & Publishers | Audience exposure value |
| RPM | Revenue per 1,000 page views | Publishers | Actual earnings |
| CPC | Cost per click | Advertisers | User interaction |
Important:
CPM measures cost, RPM measures earnings, and CPC measures user action.
Successful monetization strategies analyze all three together.
