Or you could just look at how much money goes to highly effective charities, since we’re talking about abolishing fees for all donors, not just EAs. The AMF had donations totalling 36 million in FY2020, so, using your values of 2% credit card fees, 15.4% of money donated by credit card (though I suspect the real value to be much higher, especially when considering non-EA donors) and visa holding 50% of the credit card market, that’s a total of 55′000$ for just one charity. Given that, I think it’s perfectly reasonable to say that visa eliminating their fees would increase funding for the most effective charities by hundreds of thousands if not millions of dollars a year, though I disagree with JSWinchell’s methodology
