The term “fund-raising” can be used for any activity whose primary purpose is to raise money to support the activity of a nonprofit organization. The meaning of the term “fund-raising” can change based on approaches used by a particular nonprofit organization. This chapter discusses why people donate to nonprofit organizations. The literature suggests that people donate to nonprofit organizations based on compassion, altruism, values, tax deductibility, corporate social responsibility, stewardship, and solicitation. The chapter identifies some common effective fund-raising strategies used by nonprofit organizations in the United States and describes the items in a fund-raising proposal. An effective fund-raising proposal requires effective planning. The planning of fund-raising activities should start with a fund-raising proposal that sets clear justification, goals, objectives, and overall approaches and strategies. Finally, the chapter provides conceptual frameworks and approaches to organize fund-raising activities that can generate alternative funding for financial sustainability.
