Female CEOs in the nonprofit world are still being paid less than their male counterparts. In fact, the bigger the organization, the bigger that pay gap. While women leaders make roughly 8% less than male leaders at groups with a budget of $250,000 or less, the disparity widens to 25% for groups at the $25 million or higher level, according to a recent GuideStar report. Nationally, women within the private sector generally make an average of 20% less than their male counterparts, according to the Institute for Women’s Policy Research.

GuideStar CEO Jacob Harold has a term for that. “It could be called hypocrisy,” he says, noting that many of these groups already tout gender equity as a facet of their broader social missions. Nonprofits, which account for about 10% of country’s entire workforce, also tend to have a higher number of female employees.
