Costco Wholesale's charitable giving program is dedicated to supporting community activities and charitable programs, particularly in children's welfare, education, and health and human services. The program operates on a rolling basis, accepting applications from 501(c)(3) nonprofit organizations throughout the year. The review period typically spans 4-6 weeks, during which Costco's staff may reach out for additional information.

Organizations can submit one application per fiscal year (September to August) and must ensure they meet the eligibility criteria. Decisions are based on various factors, including the nature of the program, identification of unmet community needs, evidence of measurable outcomes, and financial diversity. Applicants are advised not to request funds exceeding 10% of their program's overall budget.
