The 60% problem
A commonly cited figure in donor research is that the average nonprofit retains only about 40% of its first-time donors year over year. Flip it around: three out of every five people who give once, never give again.
Most organizations know this in the abstract. Almost none of them can tell you, for their own donor file, which specific people are in that 60% before it's too late to do anything about it.
Why it stays invisible
Retention math is easy to state and hard to operationalize. You need clean giving history, a working definition of "lapsed" that fits your organization's actual giving cycle, and some way to separate a donor who's genuinely drifting away from one who just gives annually in December. Most development teams have the first piece, part of the second, and none of the third. Building that third piece is a data science problem, not a fundraising problem, and it's rarely anyone's full-time job.
So the number gets treated as a fact of life instead of a solvable one. Everyone budgets around 60% attrition instead of asking who, specifically, is about to become part of it.
Why this is a foundation problem, not just a grantee problem
Here's the part that doesn't get said enough: if a foundation funds twenty nonprofits, all twenty of them are independently losing 60% of their first-time donors, and all twenty of them are independently under-equipped to do anything about it. Twenty organizations, one shared problem, twenty separate failures to solve it.
That's not a fundraising gap. It's a capacity gap, and it's the kind of gap a foundation is better positioned to close than any single grantee is. One retention model (or one methodology, applied across a portfolio) reaches all twenty at a fraction of what it would cost each of them to solve it alone. And it protects the foundation's own investment in every one of those organizations, since a donor base that keeps leaking is a program that keeps needing to be re-funded from scratch.
What actually moves the number
Not a better ask, not a nicer thank-you letter: those help, but they're downstream. What moves the number is knowing, donor by donor, who is trending toward lapsing while there's still enough runway to do something about it: a call, a personal note, a different kind of outreach than the one that's failing to land.
That's a prediction problem before it's a stewardship problem. You can't intervene on someone you haven't identified.
