What is CPM?
Cost Per Mille (CPM) is a marketing metric that measures the cost per thousand impressions of an advertisement. The term "mille" means thousand in Latin. CPM is widely used in digital advertising to measure and compare the cost efficiency of ad campaigns across different platforms and formats. Use this alongside our CPA Calculator and ROAS Calculator for comprehensive campaign analysis.
How to Calculate CPM
To calculate CPM, divide your total ad spend by the number of impressions, then multiply by 1,000. Use our Daily Budget Calculator to plan your campaign spending:
CPM = (Total Ad Spend / Total Impressions) × 1,000
CPM Formula
The basic CPM formula is:
CPM = (Cost ÷ Impressions) × 1,000
For example, if you spent $500 on an ad campaign that received 100,000 impressions:
CPM = ($500 ÷ 100,000) × 1,000 = $5.00
What is a Good CPM?
A good CPM varies by platform and industry, but generally:
- $1-$2 - Excellent (typically social media)
- $2-$5 - Good
- $5-$10 - Average
- $10+ - High (may be justified for targeted campaigns)
