Charity Navigator

Charity Navigator is the largest and most-utilized charity evaluator in America. The organization helps guide intelligent giving by evaluating the Financial Health, Accountability and Transparency of over 9,000 charities and provides basic data on the rest of the 1.8 million U.S. nonprofits. Charity Navigator accepts no advertising or donations from the organizations it evaluates, ensuring unbiased evaluations, nor does it charge the public for this trusted data. As a result, Charity Navigator, a non-profit 501 (c) (3) public charity itself, depends on support from individuals, corporations and foundations that believe it provides a much-needed service to America's charitable givers.
