Efficiency GradeGrade C, Median Tier on the Efficiency Score
468 nonprofits earn an Efficiency Score grade of C on NonprofitTruth, with combined revenue of $218.1B. Nonprofits scoring 50–64. Reserves and revenue trends cluster near the site-wide median; many organizations land here for structural rather than performance reasons.
What a Grade C Looks Like
A C grade — Efficiency Score 50 to 64 — clusters around the site-wide median. The 468 organizations in this tier are not all underperforming; many land at C for structural reasons (a one-off capital-campaign year, a young organization still building reserves, or revenue that swings year to year).
Grade C groups every organization whose Efficiency Score lands in this band. The grade is descriptive — it summarizes the combination of financial reserves, revenue-growth consistency, and officer-comp ratio drawn from the 990, not the social impact of the work.
The 468 grade C nonprofits in this view together report $218.1B in combined annual revenue on their most recent IRS Form 990 filings. Median revenue is $123.2M, and the simple average is $466.0M — a gap that reflects the long-tail distribution typical of the nonprofit sector, where a handful of large organizations account for most aggregate dollars.
Across the 468 grade C nonprofits we track, 0 earn an A and 0 earn a B on the Efficiency Score (combined 0% in the top two tiers, with A-grade organizations alone at 0%). Another 468 land at C, 0 at D, and 0 at F — a combined 0% in the bottom two tiers based on financial reserves, revenue-growth consistency, and officer-comp ratio drawn from each organization's most recent Form 990.
Across the grade C nonprofits where Schedule J compensation is reported, the average top executive received $3.7M in total compensation in the most recent filing year. The 990's Part VII and Schedule J break out base pay, bonuses, deferred compensation, retirement plan contributions, and non-taxable benefits separately.

How to Read a Grade C Result
The grade is a starting point. For any organization in the list above, the three factors that compose the score — financial health / operating reserves, revenue-growth consistency, and current-officer-comp ratio — are reported separately on the profile page. Reading those three numbers tells you which dimension drove the grade, which is usually more useful than the headline letter on its own.
The NonprofitTruth Efficiency Score is a 0–100 composite that summarizes three signals the IRS Form 990 feed actually reports: financial health and months of operating reserves on the balance sheet (40% of the score), revenue-growth consistency over multiple years (35%), and current-officer compensation as a share of revenue (25%). It does not include a program-spending ratio — total program service expenses are not exposed by the ProPublica Nonprofit Explorer feed, and we do not estimate that figure. The grade A–F mapping is purely descriptive — it summarizes the financial structure that the 990 reveals, not the social impact, program quality, or outcomes of the work the organization does. Donors evaluating impact should pair these financial signals with program-level evaluations from sources like Charity Navigator, GiveWell, or the organization's own audited reports.
Mid-tier scores reward steady financials. They do not penalize organizations that are deliberately investing in capacity (which can draw down reserves temporarily) or organizations with reserve-building strategies that take a multi-year timeframe to mature.
Source Data and Verification
All financials on this page come from each organization's IRS Form 990 — the federal information return that 501(c)(3) public charities, private foundations, and most other tax-exempt organizations must file annually. The Form 990 is a public document. We ingest it primarily through the ProPublica Nonprofit Explorer feed, which mirrors the IRS Tax-Exempt Organization Search dataset. Original e-file XML and PDF copies of any return can be looked up directly at the IRS, ProPublica, or the Candid (formerly GuideStar) directory.
Each organization in this grade band has its underlying Form 990 available free of charge from the IRS Tax Exempt Organization Search, the ProPublica Nonprofit Explorer, or the Candid (GuideStar) directory.
Frequently Asked Questions
What does a grade of C mean?
Nonprofits scoring 50–64. Reserves and revenue trends cluster near the site-wide median; many organizations land here for structural rather than performance reasons.
How is the grade calculated?
The Efficiency Score is a 0–100 composite of three Form 990 signals: financial health / months of operating reserves on the balance sheet (40% weight), revenue-growth consistency over multiple years (35%), and current-officer compensation as a share of revenue (25%). It does not include a program-spending ratio, which our data source does not provide. The 0–100 score maps to a letter grade — A for 80+, B for 65–79, C for 50–64, D for 35–49, F under 35.
Does grade C mean a charity is average?
No — the grade is descriptive of financial structure on the IRS Form 990, not of program impact. A grade C organization may run highly effective programs that this score cannot measure, or may have a structural reason for its score (capital campaign, young reserves, sector classification) that does not reflect performance. Always pair the grade with program-level evidence from sources like Charity Navigator program reviews, GiveWell impact evaluations, or the organization’s own annual report.
Why might similar nonprofits have different grades?
Two same-category, same-revenue-tier organizations can land at different grades because of differences in the level of unrestricted reserves on the balance sheet, the steadiness of multi-year revenue, the timing of capital expenditures, or one-time deferred-compensation events. Reading the three-factor breakdown on each organization’s profile page — financial health / operating reserves, revenue-growth consistency, and officer-comp ratio — shows which dimension is driving the grade.
Where can I see the original Form 990?
Click any organization on this page to open its profile. The profile cites the source filing year and links to the original return on the IRS Tax Exempt Organization Search and the ProPublica Nonprofit Explorer.
