Here's the tension: total giving is growing, but donor counts keep slipping. FEP's full-year 2025 data shows dollars raised grew an estimated 5.0%, while the number of donors declined roughly 3.6% — continuing a trend that started in 2021. Fewer people are giving more money. That gap is exactly why metric tracking can't be optional anymore.
This guide breaks down the fundraising, financial health, and program-outcome metrics nonprofits need on their dashboard this year.
Key Takeaways
- Track fundraising, financial health, and program-outcome metrics together. Funders now expect all three.
- Donor retention and cost-to-raise-a-dollar predict sustainability better than any single revenue figure.
- Centralized case management turns scattered data into funder-ready reports without extra staff hours.
Why Metrics Matter More Than Ever in 2026
Watchdogs like Charity Navigator and GuideStar have trained donors to expect transparency. Funders increasingly ask not just "how much did you spend on programs" but "what changed for the people you served." Metrics answer both.
Candid's impact-measurement research found that 76% of nonprofit decision-makers call measuring impact a top priority, yet only 29% feel their organization is effective at demonstrating outcomes. That 47-point confidence gap is why, heading into 2026, more organizations are replacing spreadsheet tracking with dedicated reporting tools funders actually trust.
Lagging vs. Leading KPIs
- Lagging KPIs measure what already happened: total dollars raised, program expense ratio, donor count
- Leading KPIs predict what's coming: donor retention rate, gift frequency trends, case closure rate
A healthy dashboard needs both. Lagging metrics tell your board how last year went. Leading metrics show what to expect next year and give staff time to course-correct.
Fundraising & Donor Metrics to Track
Donor Retention Rate
Formula: Donors who gave again this year ÷ total donors who gave last year × 100
This is the single most predictive metric for sustainable fundraising. FEP's 2024 report put overall retention at 42.9%, with new-donor retention at just 19.4% versus 69.2% for repeat donors.
Candid has separately noted sector retention hovering closer to 45%. If your rate sits below 40%, your acquisition pipeline is likely leaking faster than you can fill it.
Average Gift Size and Donor Growth Rate
- Average gift size = total donations ÷ number of donations
- Donor growth rate = (current year-end donors − prior year-end donors) ÷ prior year-end donors × 100
A rising average gift with flat donor growth often signals successful mid-level or major-gift cultivation. Falling donor growth paired with rising dollars, which is exactly what FEP's data shows sector-wide, means you're becoming more dependent on fewer people.
Cost-to-Raise-a-Dollar and Fundraising ROI
- Cost-to-raise-a-dollar = total fundraising expenses ÷ total fundraising revenue
- Fundraising ROI = (donation revenue − fundraising cost) ÷ fundraising cost × 100
The BBB Wise Giving Alliance sets a ceiling of 35 cents spent per dollar raised under its accountability standards. Use ROI to compare channels (direct mail, events, digital) so budget goes where it performs.
Donor Lifetime Value
Formula: Average donation amount × average donation frequency × average donor lifespan
This number should drive your acquisition spending. If a donor's lifetime value is $2,000, spending $150 to acquire them through a paid campaign is a reasonable bet.
The 80/20 Question
Many fundraisers ask whether the "80/20 rule" holds true: roughly 80% of revenue from 20% of donors. There's no single universal statistic confirming that exact split, but FEP's 2024 segmentation comes close.
Major and supersize donors made up just 3.1% of donors but generated 77.7% of dollars. Whatever the precise ratio at your organization, track donor concentration and build a major-gift strategy around it.
Financial Health & Efficiency Ratios
Fundraising success means nothing if the money isn't managed well. Funders check these ratios before they check anything else.
| Ratio | Formula | Benchmark |
|---|---|---|
| Program expense ratio | Program expenses ÷ total expenses | 65%+ per BBB Standard 8 |
| Fundraising expense ratio | Fundraising expenses ÷ related contributions | Under 35% per BBB Standard 9 |
| Current ratio | Current assets ÷ current liabilities | No universal figure; track the trend |
| Operating reserve | Liquid unrestricted assets ÷ monthly expenses | 3-6 months, per National Council of Nonprofits |
| Liabilities-to-assets | Total liabilities ÷ total assets | Approaching 50% signals debt-management risk |
A quick note on that 65/35 split: it's often quoted as one benchmark, but BBB actually measures program expenses against total expenses and fundraising expenses against related contributions — two different denominators. Don't force them into one neat ratio when reporting to your board.
Operating reserves need closer watching than the other ratios. Nonprofit Finance Fund notes that fewer than three months of reserves can leave an organization dangerously exposed, depending on funding volatility and facility costs.
If your reserve ratio has been shrinking for two straight quarters, raise it with your board before a shortfall forces the conversation.
Program & Client Outcome Metrics (The Overlooked Fundraising Advantage)
Funders no longer stop at financial ratios. They want to know what happened to the people you served, and this is where most nonprofits are weakest.
Core outcome metrics to track:
- Number of unique clients served (not duplicated across programs)
- Service duplication rate across partner agencies
- Case closure or goal-achievement rate
- Change in client status over time (housing stability, employment, well-being)
That last one matters most for grant renewals. Tracking a client's status at intake versus exit (stable housing, employment gains) gives funders concrete evidence instead of a narrative summary.
This is where case management software earns its keep. CharityTracker's Changes Over Time Report lets organizations build customizable assessments and measurement checkpoints, tracking each client's progress from intake through program completion or independence.
Fields commonly tracked include housing stability, employment support, and social or academic progress for youth programs, all without staff building a separate spreadsheet for every grant cycle.
Duplication is another metric funders watch closely. CharityTracker's shared case management database lets authorized staff at partner agencies see a client's prior assistance history in real time, which helps prevent overlapping payouts.
One ministerial alliance customer reported an average 91% reduction in duplicated services after adopting shared case tracking. That figure comes from a single customer rather than a sector-wide benchmark, but it shows what inter-agency visibility can deliver.
Trident United Way, a CharityTracker customer for 12 years, described the platform's role in helping "break cycles of generational poverty" by giving caseworkers visibility into what assistance clients had already received across the network.
Choosing, Tracking, and Reporting Your KPIs
Having more metrics isn't better. Most consultants recommend 5-7 KPIs tied directly to your strategic goals, not a 40-tab spreadsheet nobody opens. A practical starting set:
- Donor retention rate
- Cost-to-raise-a-dollar
- Program expense ratio
- Operating reserve ratio
- Case closure / goal-achievement rate
- Unique clients served
- Average gift size Manual tracking is where most of this breaks down. One CharityTracker customer, an office clerk handling first-call intake, put it simply: "The software is so user-friendly that I have cut my paperwork time in half, at least!" That reduction came from replacing duplicate spreadsheets and manual board reports with centralized, automated reporting. Review cadence matters too:
- Monthly for program and development staff: catch problems early
- Quarterly for board members: spot trends without drowning in noise
- Annually for the full team: revisit your KPI list and swap out metrics that no longer match your strategy

Commonly cited core KPIs are donor retention rate, program expense ratio, fundraising ROI, average gift size, and operating reserve ratio. Together they cover fundraising health, financial efficiency, and sustainability.
What is the 80/20 rule in fundraising?
It's the idea that roughly 80% of donations come from about 20% of donors. FEP's data shows an even sharper concentration — just 3.1% of donors generated 77.7% of dollars in 2024 — reinforcing the case for major-gift cultivation.
What are the key financial ratios for nonprofits?
The core ratios are program expense ratio, current ratio, operating reserve ratio, and liabilities-to-assets ratio. These show funders how efficiently you spend money and how well you can weather a revenue dip.
How often should nonprofits review their metrics?
Staff should review KPIs monthly to catch issues early, while boards typically review quarterly for trend analysis. Annual reviews help you retire outdated metrics and add new ones as strategy shifts.
What software can help track nonprofit fundraising metrics?
Donor CRMs track gift-level KPIs such as retention and average gift size. Case management platforms like CharityTracker complement them by centralizing program outcomes and funder-ready reports—including Changes Over Time—that prove impact to donors and grantmakers.
