On YouTube, RPM bundles ad revenue, Premium revenue, Super Chats, and memberships, divided across total views — including views that served no ads. That is why RPM always runs well below CPM: a $20 CPM might translate to a $7 RPM after the 45% platform share and non-monetized views are factored in.
RPM thinking applies beyond YouTube: shortform programs like the TikTok Creator Rewards Program and YouTube Shorts pay dramatically lower effective RPMs than longform video, which is why view counts alone say little about income. Creators use RPM to compare formats, decide where a niche's money actually is, and model income from projected views.
