Money made simple
Ask these three easy questions
- Who did you help? Ask for a recent story or report that shows real results.
- What will my money do? Ask exactly what your gift will pay for.
- Is this really the charity? Give only through its official website or confirmed phone number.
Worth asking: Expenses exceeded revenue this year. Ask whether that was planned or caused by a one-time event. The complete report shows the exact difference and financial history.
Bottom line: Do not decide from a name, mission statement, or tax status alone. Look at where the money went, then ask what changed, who was helped, and what your gift will do. YouCanGiveBack does not endorse or grade organizations.
