CPM Calculator — Cost Per Thousand Impressions
CPM (cost per mille) is the standard way to price and compare display advertising. This calculator works in all three directions: find CPM from cost and impressions, find cost from CPM and impressions, or find impressions from a budget and CPM.
The Formula
CPM = (Total Cost ÷ Impressions) × 1,000. So $500 spent for 250,000 impressions is a $2 CPM. To plan a campaign, Impressions = (Budget ÷ CPM) × 1,000, and Cost = (CPM × Impressions) ÷ 1,000.
Why Publishers and Buyers Use It
CPM lets you compare ad placements of very different sizes on equal footing, and lets publishers estimate revenue from expected traffic. It is the core metric behind most programmatic and direct ad deals.

Free CPM Calculator Online — Calculate Formula Instantly — Frequently Asked Questions
Got questions about Free CPM Calculator Online — Calculate Formula Instantly? Here are clear, honest answers to the most common questions about pricing, privacy, compatibility, and features.
What does CPM mean?
CPM stands for cost per mille, or cost per thousand impressions. It is the price an advertiser pays for one thousand views of an ad.
How do I calculate CPM?
Divide the total campaign cost by the number of impressions, then multiply by 1,000. $300 for 150,000 impressions is a $2 CPM.
How many impressions can my budget buy?
Divide your budget by the CPM and multiply by 1,000. At a $4 CPM, a $1,000 budget buys 250,000 impressions.
Is CPM the same as CPC?
No. CPM charges per thousand impressions regardless of clicks, while CPC (cost per click) charges only when someone clicks the ad.
