CharityNavigator score: 69.37 out of a possible 70 Backed by top celebrities and business titans, the Robin Hood Foundation gives more than $100 million a year to New York City antipoverty groups that produce results the charity can measure with Wall Street-style analytics. For instance, the Robin Hood Foundation boasts on its website that 92% of those who enroll in its housing programs never return to homeless shelters. CharityNavigator gives the Robin Hood Foundation a four-star rating, as the nonprofit meets all 17 of its accountability and transparency tests and spends 91.1% of all donations on good works. Less than 9% of money raised goes toward fundraising and overhead, and the group's blue-ribbon board -- whose members range from General Electric ( GE) CEO Jeffrey Immelt to actress Gwyneth Paltrow -- covers that themselves. Everyone else who donates will see 100% of their contribution go toward poverty-fighting efforts.
