When I was in the military, I learned about the Combined Federal Campaign, which aggregates charities and allows federal employees to contribute through payroll deductions. https://cfcgiving.opm.gov/offerings https://cfcgiving.opm.gov/offerings One tool they offer is a calculation of AFR, which is the Administrative and Fundraising Expense Rate. It basically measures the overhead you're talking about. You can look it up for any charity that's part of the CFC at the link above. The EFF's AFR is over 30%. The Red Cross's AFR is a touch over 9%.
