RPM

YouTube introduced RPM as a creator facing reporting metric precisely because CPM confused people. RPM is calculated by dividing total earnings by total views and multiplying by a thousand, and it includes every revenue source in Studio, so channel memberships, Premium watch time, and Super Chat all raise it alongside ads.

That makes it the practical number for planning. If a channel runs at four dollars RPM, a hundred thousand views is roughly four hundred dollars, and that estimate already accounts for the revenue share and unmonetised views. Forecasts built on RPM tend to land close, while forecasts built on CPM tend to be several times too high.

The nuance is that RPM is a reporting term, primarily YouTube's, and it moves with the mix of your audience rather than with quality. A channel that shifts from long form to Shorts usually sees RPM fall, because the Shorts revenue pool is shared differently, and a channel that grows in lower advertising markets will see it fall even as views rise.

For planning, take a rolling three month RPM rather than one strong month, since seasonal advertiser demand distorts any single reading. Run that figure against realistic view counts in a CPM and RPM calculator before committing to a content schedule, and revisit it whenever the mix of long form and Shorts changes.
