About CPM Calculator HQ

CPM Calculator HQ is a small set of free calculators for marketers, media buyers, small business owners and creators: a CPM calculator plus calculators for CTR, CPC, CPA and ROAS.

How the numbers are made

Every calculator uses the standard industry formula, shown on its page and repeated with your numbers next to each result, so you can check the working. Everything is calculated in your browser; nothing you type is sent to us.

How the site is funded

The site is free to use. It may show advertising and may contain affiliate links: if you buy something through such a link, we may earn a commission at no extra cost to you. Advertisers do not influence the calculators or the content.

Important

Results are calculations from the numbers you enter. Ad platforms count impressions, clicks and conversions in their own ways, so always compare against your platform's reporting before making budget decisions.

Who runs the site

CPM Calculator HQ is run by HRose Mariola Świderek, ul. Olchy 37/2, 05-506 Magdalenka, Poland.
