The Right Fundraising Metrics to Protect Donor Retention

by Derric Bakker

Few nonprofit leaders would ever intentionally design a fundraising system that exhausts staff, frustrates donors and rewards short-term revenue at the expense of long-term generosity. Yet many organizations find themselves in exactly that situation. That would be less of a problem in a forgiving environment. This is not one.  

The Center for Effective Philanthropy’s “State of Nonprofits 2026: What Funders Need to Know” describes a sector absorbing rising demand and contracting funding at the same time: Roughly three-quarters of organizations report greater demand for their services since early 2025, even as foundation and government support have declined.  

At the same time, the fundraising engine is sputtering. The rate at which Americans are giving to charity is in decline. The cost to acquire new donors is at an all-time high, and donor retention rates are near all-time lows.  

The Fundraising System Is Under Strain 

This is not a passing storm. Something fundamental is shifting in how people give. Donor counts have been falling since 2021, while retention — particularly first-time donor retention — has declined for nearly a decade. Trends that persist this long are not a cyclical dip. They are symptoms of a system under strain, caused by structural shifts in the philanthropic landscape.  

Two shifts in particular stand out: 

1. Giving is consolidating. A shrinking number of larger donors now account for most dollars raised. The Fundraising Effectiveness Project’s data shows that revenue growth in recent years has come almost entirely from major and supersize gifts, even as the total number of donors has declined. 
2. Younger donors give in fundamentally different ways than previous generations. When they do give, they behave remarkably like major donors — selective, impact-focused and partnership-oriented.  

Traditional mass-market fundraising tactics are largely ineffective with both these groups. Most nonprofit leaders recognize that today’s fundraising models need to move away from transactional fundraising toward more relationship-based approaches. Not because it’s trendy, but because it’s the only approach aligned with how today’s donors behave.  

Old Metrics Reward the Wrong Behaviors 

These shifts are outpacing the fundraising metrics we use to evaluate fundraising success. All too often, the metrics we rely on today are quietly rewarding the very behaviors undermining long-term fundraising health.  

In a relationship-first fundraising environment, giving is multichannel and interconnected. Donors encounter organizations through direct mail, email, events, websites, social media, referrals, board relationships, donor-advised funds and personal conversations. They do not experience isolated campaigns. They experience an organization.  

But many development dashboards are still built for a different era — one defined by single-channel campaigns, mass response and straight-line attribution.  

Donor behavior is changing fast, yet traditional metrics remain largely intact: gross dollars raised, donor file size, response rate and campaign-level performance. These metrics are not passive scorecards. They are behavioral incentives. What leaders measure, teams optimize.  

Gross Revenue Can Hide Costs 

Gross revenue tells leaders how much money came in, but not what it cost to produce. These metrics also reward volume and urgency, not relationship. As a result, they tend to incentivize the very behaviors that burn donors out: frequent, mass-produced appeals, manufactured scarcity and one-size-fits-all treatment.  

Donor File Size Can Prioritize Acquisition 

Donor file size rewards acquisition, often at the expense of retention. For years, nonprofit orthodoxy prioritized investing in acquisition above all else. But when acquisition costs per donor exceed triple digits and first-year retention rates drop below 20%, that logic begins to collapse. You cannot acquire your way to sustainability when you’re losing donors faster than you can replace them.  

Campaign Performance Favors Short-Term Urgency 

Short-term metrics like response rate and campaign performance reward urgency. Organizations optimizing for response rate train themselves to be better at near-term extraction, not long-term partnership.  

Attribution Can Fragment the Donor Experience 

Then there is attribution — one of the most distorting forces in fundraising. Attribution asks: Which channel caused this gift? Which team gets credit for it? On the surface, these are reasonable questions. But attribution rests on the false assumption that generosity can be reduced to a single trigger. That is rarely how giving works today.  

A donor may receive direct mail, read emails, attend an event, speak with a board member and give through a donor-advised fund. Which channel caused the gift?  

When attribution becomes the primary way organizations evaluate performance, it leads to channel silos, internal competition and fragmented donor experiences.  

Build a Better Fundraising Dashboard 

The answer is not less accountability. It is better accountability. Nonprofit leaders and boards need a scorecard that measures fundraising system health, not merely activity.  

That starts with asking better questions:  

• Is net revenue — not just gross revenue — growing?  

• Are we balancing investments in acquisition, cultivation and retention?  

• Are donors not just staying, but deepening their commitment?  

• Are donors becoming more engaged across channels and over time—not through isolated clicks, but through evidence of growing connection?  

• Is lifetime giving accelerating or decelerating? The goal is not simply the next gift, but durable generosity over time.  

These are not soft metrics. They are leading indicators. They reveal whether the fundraising system is becoming healthier, more integrated and more durable. They help boards see beyond the noise and ask whether the organization is building the kind of donor relationships that can sustain mission impact for years to come.  

Measure Relationship Health 

This shift requires discipline because old metrics are easier. They are familiar. They fit neatly into board packets. They create the appearance of clarity. But simple numbers can create false confidence when they obscure the deeper condition of the donor base.  

A better fundraising dashboard does not ignore revenue. It simply refuses to measure revenue apart from retention, cost, engagement and long-term value. Fundraising will not be renewed simply by adding more channels, adopting more technology or asking exhausted teams to work harder.  

The sector needs a better way to define success. The scorecard determines the game being played. If we measure volume, we will get volume. If we measure urgency, we will get urgency. If we measure attribution, we will get competition for credit.  

But if we measure relationship health, donor loyalty, net value and long-term generosity, we will build systems designed to produce them.
