In 2005, the average nonprofit retained 43% of its donors year-over-year. In 2025, that number sits at 44%. Despite two decades of innovation—digital campaigns, AI-powered personalization, sophisticated CRM systems—we’ve moved sideways on the metric that matters most.

This is the 67% Problem: two out of three first-time donors never give again.

The stagnation makes no sense. Nonprofits now track donor behavior across channels, segment audiences with precision, and automate personalized communications at scale. Tools that would have seemed like science fiction in 2005 are now standard. Yet donors still disappear at alarming rates, particularly first-time givers who represent any organization’s future funding base.

The question isn’t whether organizations are trying. Most development teams obsess over retention. The question is why their efforts haven’t worked.

The Hidden Identity of Donor Retention

Most nonprofits treat donor retention as a marketing problem. It’s actually an identity problem.

Consider the difference: “I donated to cancer research” versus “I’m someone who supports cancer research.” The first describes a transaction. The second describes an identity.

James Clear writes in Atomic Habits that “the ultimate form of intrinsic motivation is when a habit becomes part of your identity.” The same applies to philanthropy. When someone gives once, they’ve performed an action. When they give consistently, they’ve adopted an identity. The gap between those states is where 67% of donors disappear.

Most retention strategies focus on the wrong mechanism. They try to convince previous donors to give again through emotional appeals, impact reports, or renewal reminders. These tactics treat giving as a decision to be made rather than an identity to be reinforced. It’s the difference between asking “Will you donate?” and demonstrating “You’re already the kind of person who does this.”

Why the Standard Playbook Fails

The conventional wisdom follows a predictable pattern: thank donors quickly, report impact clearly, ask at the right time, personalize communications. These aren’t bad practices—they’re necessary but insufficient.

They operate at the surface level. A thoughtful thank-you letter makes someone feel appreciated, but doesn’t change how they see themselves. An impact report demonstrates stewardship, but treats the donor as an evaluator of organizational performance rather than someone whose identity is intertwined with the mission.

Consider the first 48 hours after someone makes their initial donation. Most organizations send a tax receipt and generic welcome email. Some trigger an automated series. The best include a personal call or video message. But very few do what actually matters: help the donor see their gift as evidence of who they are becoming.

This is the retention gap. The organization views the first gift as the end of an acquisition process. The donor experiences it as an experiment—testing if giving feels aligned with their values. When organizations fail to bridge that gap, the experiment ends and the donor moves on.

The System That Actually Works

Effective retention isn’t built on better asks or creative campaigns. It’s built on “identity scaffolding”—systematic touchpoints that help donors see giving as part of their self-concept.

The most successful retention systems share three characteristics.

First, they create immediate belonging. Within days of a first gift, new donors receive something that signals membership, not just acknowledgment. A welcome package positioning them as part of a community. An invitation to an insider briefing. Access to a donor portal with their name on it. The goal isn’t impressive materials—it’s tangible evidence that they’re now “in.”

Second, they manufacture small wins. The brain loves evidence supporting existing beliefs. When someone donates, they’ve taken a step toward seeing themselves as a supporter. Smart organizations immediately provide proof this identity is correct. They show how the specific gift is being used, introduce someone the money is helping, or demonstrate immediate impact. Each piece of evidence makes the identity more concrete.

Third, they remove friction from identity expression. The easier it is to behave according to an identity, the more likely it sticks. This is why monthly giving converts so well—it automates the behavior that reinforces the identity. Once someone sets up recurring giving, they don’t continually re-decide whether they’re “the kind of person who supports this cause.” The system decides for them.

The Compound Effect of Small Improvements

The retention math gets interesting here. Improving first-year retention from 33% to 43%—just 10 percentage points—compounds dramatically. Over five years, assuming consistent retention rates afterward, an organization would have 38% more active donors. The revenue implications are larger still because retained donors typically increase giving over time.

Most organizations never see these gains because they chase the wrong metrics. They measure response rates, average gift sizes, total dollars raised. All important, but none directly measure whether they’re helping donors adopt a giving identity.

Organizations that crack retention measure differently. They track the percentage of first-time donors engaging with identity-building content. They monitor how quickly new donors self-identify as “supporters” in surveys. They watch the timing gap between first and second gifts, knowing shorter gaps correlate with stronger identity formation.

What This Means for You

If you’re leading fundraising for an organization struggling with retention, the solution isn’t more appeals or better impact stories. It’s redesigning your first 90 days around identity formation.

Ask yourself: What are we doing in the first week after a gift to help this person see themselves as a supporter rather than a transaction? What evidence reinforces this new identity? How are we removing friction from their next opportunity to express this identity through giving?

The 67% Problem persists not because organizations lack effort or resources, but because they’re optimizing the wrong system. They’re trying to improve donor communications when they should be engineering donor identity.

Twenty years of stagnation tells us incremental improvements to existing strategies won’t solve this. What’s needed is a fundamental reframe—from treating donors as customers to be retained to treating giving as an identity to be cultivated.

The organizations that make this shift won’t just improve retention by a few percentage points. They’ll fundamentally change the relationship between their mission and the people who fund it. And unlike the last 20 years, the next 20 might actually look different.
