How Much Can You Make With Chess Coaching?

There are some topics, there are some old posts... but most of them are blablabla and won't give you nice answer, because they love answering it depends, probably to not make anyone angry. alright now i ask how much Money can titled player(CM,FM,IM and GM) make with online coaching. I investigated little bit and i think even a friendly CM can charge up to 30$ for 1 hour lesson, but as i know chess.com takes 20% so he gets 24$ but how big is demand for chess lessons? i mean if a guy gives 5 lesson per day(5 days per week) he can make 2400$ per month(29000$ year) which is not bad for economically strong countries and is amazing for not so wealthy countries, but as i mentioned above. will you students easily? i mean we have circa 10K titled player. there are 125 coaches on this site and more than 20M members so demand should be quite good. What you guys think about this? if some titled chess coach would share with us would be great, but probably they won't do it.
well, when I have even just 2 days in a row with the lessons for at least 5 hours a day I feel extremely tired. So I can't unterstand why a coach need to work the whole year with such schedule without the holidays, without any chess tournaments to play himself, it doesn't make any sense, simply too much in my opinion.
And who said that chess.com takes smt from the coaches? It's not true.

Yep i am sure it's not easy, but still it's quite nice when you can do your job without going from home and also do a job which at least you do not hate. 5 hours are a lot. how many hours do you teach in week?
P.S. Slava Ukraini!

It seems to be a good source of supplementary income, but not a standalone way to make a living.
Personally, a retired chemistry and physicis teacher who wrote the Semester Exams in Physics used in all 12 of the public high schools in my county, I can charge $40/hr for tutoring and get 2-3 hrs/day of tutoring. Some retired teachers had children late in life or foolishly have large debts, etc. and do tutoring. But I don't need the extra income so I don't do it.
My guess is that most chess masters would not take on students if they didn't need the additional income, and those who do find their financial situation more comfortable than without it, so they coach chess: a win-win for all.
There are some who have managed to make an industry out of it, but they are rare!
