That's just what I was about to post. There's always that part about "expenses" and taxes and there's no way around it since Youtube/Google has to send everyone a 1099. I get one every year from Adsense
If you were going to post that, then that shows that neither the Vegan Gains or the Hodge Twins can be making anywhere near the numbers you posted.
Vegan Gains channel has 23mil views. If he gets paid $2000 for every million views (CPMs have actually dropped significantly even since this article was published) then that's $460000. The Hodge Twins have two channels with cumulative views of about 400mil. One channel is about 8 years old and the other is 5 years old. When you factor in youtube's cut, they are making about $40,000 a piece based on that article.
But that's only a rough outline. It could be less or more based on how youtube distributes the ads. But it's definitely not half a million for the Hodge twins. $40,000 is nothing to sneeze at, though.
