About CPM Calculator
A free, focused tool for anyone who needs to work out CPM, ad cost, or impressions without digging out a spreadsheet.
What This Site Does
CPM Calculator lets you calculate CPM from ad spend and impressions, or solve for total cost or impressions when you already know the CPM. It also documents the underlying formulas — for CPM, eCPM, and converting CPC to CPM — so the numbers it gives you aren't a black box. The blog goes further into specific platforms and pricing models.
Who It's For
Advertisers budgeting a campaign, publishers pricing inventory, and marketers who just need a quick, reliable answer without manual math or spreadsheet formulas.
Privacy by Design
The calculator runs entirely in your browser. The numbers you enter are processed locally with client-side JavaScript and are never sent to or stored on any server. See the Privacy Policy for details.
