Plus the at least $15k a month (7614 patrons at the lowest $7pm pledge, minus a Patreon's 10% cut, divided by three) he's making from his other shitshow, Kill James Bond. Christ on His throne, what a grift!!
The "Members" on Patreon is misleading. It's a change they made a year ago where they started lumping in non-paying followers of a creator with their paying supporters in the count on the home page.
Best pics I have of when the change happened, it broke Graphtreon for a bit last october.



It made it look like Choob got 3,000 extra patrons out of nowhere without any correlating happening. This spike is all gone from the graph today.
(He's been back on a steady downward trend for quite a while now. Any takers on what he will do to drum up support this time? The first spike in members is his Coming out, for the second he drummed up support with the NHS video.)
So Choob has 12,688 members, but under his about page you can see that he only has 6,564 paid members


Likewise for KJB there are 7,614 members, but only 5,562 paid members

Clicking on that "Join for free" button makes you one of the Total members, but not one of the Paid members.
Estimate of KJB-earnings
We have a lot less to go on with KJB in regards to calculate earnings, there's some "Monthly Roll Of Honour" that all patrons above and including $13,50 show up in which I don't really have a clue as to what it could be. At the end of a KJB-episode there is however a readout of all the patrons who pay $20 or more. The readout goes on for ~2 minutes minus some talking in-between names but I'm having a hard time discerning what's a name or not. Assuming a rate of a little less than one name per second I'm guessing about 200 people give $20+, which I think is being generous but I don't have any reasonable estimate.
So with that as a baseline the earnings would be at minimum:
5362*7 = 37,534
200*20 = 4000
41,534
Assume they're on the Patreon Pro plan where there's an 8% cut (KJB is too recent to have the legacy plan)
41,534*0.92 = 38,211
Dividing that by three gives us:
$12,737 pre tax per person
Without knowing what the "Roll Of Honour" is there's no point to estimating an upper bound. But if somebody figures that out we can go to town.
