YouTube RPM vs CPM: What's the Difference?
Why is your RPM always lower than your CPM in YouTube Studio? Here is how YouTube's 45% revenue cut and non-monetized views work.
The Core Difference
CPM (Cost Per Mille) is the price an advertiser pays for 1,000 ad impressions before YouTube takes any fees.
RPM (Revenue Per Mille) is the actual money you earn per 1,000 total video views after YouTube takes its 45% platform fee.
The Revenue Split Math
Creator Revenue = Gross Ad Spend × 55%
