Monetisation & Revenue
Estimated Revenue
Also called: estimated earnings
Studio shows it for the channel and per video in the Content tab, across whatever date range you pick. The number pulls together the revenue types YouTube pays out: ad revenue, the share of Premium watch time, channel memberships and the fan funding features.
Estimated is the operative word. The figure in Analytics is YouTube's own calculation, it can move, and the amount that eventually lands is settled in AdSense. Creators also read it as a wage when it is a gross figure, before tax and before the cost of making anything, which is how a healthy looking month turns thin by the time it reaches a bank account.
