The most common question donors ask
The most common question(s) from prospective donors: “How much of my money goes to program versus overhead, and what can you tell me that will show me how well you spend your money?”
I know this from my experiences at nonprofits (it’s always the #1 customer inquiry) and my friends from Sea Change, who’ve heard a lot of focus group participants ask those questions.
My question to you: Are you answering this question on the home page of your website? The first page of your direct mail? You need to.
Mercy Corps does an especially good job of this.

This is a perfect example of the difference between answering donors’ questions narrowly and answering them broadly, between giving them their data and helping them pursue their values, between “the customer is always right” and “the customer is on your side.”
“How much of my money goes to program vs. overhead” is not a meaningful way to assess a charity. Charities know this and I imagine you do too. Donors ask for this information because they’ve been told to ask for it, not because it’s the right way to get what they really want.
In the end I agree with the literal msg of this post - since it’s a common question, it’s only practical to put the answer where it’s easy to find - but charities should always accompany this info with a link to something more meaningful. A donor who asks this question is trying to intelligently evaluate efficiency/effectiveness. Charities should help them with this, not just do what they say.
