It’s never about the subscriber. It’s all about the number of views and activity on their videos.

I have seen people with a million subscribers not earning anything and have seen people with 50k subscribers making good money.

Money on youtube is generally generated from the ads on the video. The more views your video will have, the more ads will show up and the more money you’ll make out of it.

Suppose you’re having 100k views on your one video.

Then you can expect something about 100–200$ from that video.

Again, It is also about type and quality of ads. So you can face different cpc and rpm on your videos
