YouTube CPM Calculator

CPM (Cost Per Mille) is what advertisers pay YouTube per 1,000 ad impressions — before YouTube's share. Enter gross ad revenue and monetized impressions to compute your CPM.

Gross ad revenue

Monetized impressions

CPM

CPM is undefined when monetized impressions is zero.

Formula: CPM = gross ad revenue / monetized impressions × 1000

CPM is not RPM. CPM measures what advertisers pay per 1,000 monetized impressions (before YouTube's share). RPM measures what the creator earns per 1,000 total views (after YouTube's share). A higher CPM does not automatically mean higher take-home revenue.

FAQ

What is CPM?: CPM (Cost Per Mille) is the amount an advertiser pays per 1,000 ad impressions. It's an advertiser-side metric.
Why is my CPM higher than my RPM?: CPM is before YouTube's revenue share and only counts monetized impressions. RPM is after YouTube's share and divides by all your views (including non-monetized ones). RPM is always lower than CPM.
Is this an official YouTube tool?: No. This is an independent calculator.
