Ah, thanks, good to know where it came from. That doc is actually outdated (it uses data up to the end of 2013 only), the more recent figure is 104:1, which gives you something more like £460 per member. You can always find our most up to date impact evaluation of ourselves at givingwhatwecan.org/impact. Our cost per member seems to have been dropping over time. This is one of the key numbers we track in our yearly reviews, all of which you can find on this page.
FYI: I have updated the estimated returns and relevant data above. Happy to chat further if you think it would be helpful for improving the figures here.
