Do you know if they actually work out the ratio this way? (protected legacies from people who sign up)
I’d have guessed it was calculated by comparing one year’s legacies received with outgoings. This has some other issues, like being an average rather than marginal effectiveness.
I meant whoever produced figures for the ratios. I guess I was envisioning the Institute of Fundraising, but only because I recently saw some figures from them.
Edit: It seems Charity Science have an overview of this linked in another comment. They have a summary of other studies, but I don’t know the methodology for these other studies. They have a Fermi estimate themselves (and they don’t discount), but the error bars are large and I think this is more of a sanity check on the other figures—it’s not clear discounting should change the overall conclusion too much, except perhaps pushing against a focus on young people.

By ‘they’ do you mean Charity Science? Is that who Ben Todd’s talking about?
