Abstract
The increasing use of donor-advised funds (DAFs) creates challenges for nonprofit managers and fundamentally changes the way that many donors give to charity. We conducted 48 in-depth interviews with DAF donors to understand their strategies of how they give through a DAF. From the interviews, we found three distinct models of DAF giving strategies: tubs, tanks, and towers. Tub donors give quickly through a DAF, moving money in and out annually. Tank donors contribute large lump sums and grant the money away in the relatively near future. Tower donors take a calculated approach with the DAF to sustain their philanthropic activity over time. Several factors relate to these strategies, including the sources and timing of contributions, different purposes of grantmaking, tax implications, investment strategies, and family involvement. Our findings may help nonprofit managers, fundraisers, and other stakeholders to better understand the various ways donors give through DAFs.
