You can find figures and such here.
As both a creator and a patron to other creators, I don’t mind paying fees either way. They’re part of the deal, inescapable. However, I don’t think this is fair to patrons - this isn’t your problem. You didn’t choose to put me or the other creators you support on Patreon, we did. We chose this, fees and all.
If you, as a patron, cannot afford to support your favourite creators anymore, please do not feel pressured into staying. As artists, it is up to us to adapt, as we did before Patreon was an option.
As many others have already expressed, we are routinely overwhelmed and surprised by the generosity of patrons! You already do so much! We do not expect you to do more.
If you would like to stick it out, excellent, you’re very welcome! But we understand that for many, this hits too hard.
