Question: how much money can you make with a million subscribers?
Answer: Lets assume the average CPM for a YouTuber with 1 million subscribers is around $4 dollars. YouTube takes a 45% cut and sometimes the YouTuber also has Multi Channel Network representing who also takes around 45%. So the You Tuber, who gets on average 600k+ views a week, will end up with around $1-3k a week from CPMs.
