In the American Institute of Philanthropy’s view, 60% or greater is reasonable for most charities and the most highly efficient charities are able to spend 75% or more on programs.
From the AIP website: "AIP is a nationally prominent charity watchdog service whose purpose is to help donors make informed giving decisions."
We spend the remaining percentage on fundraising efforts and general administration.*
* AIP has not officially rated The Leakey Foundation.
