The Overhead Ratio and the Overhead Myth: What Nonprofit Leaders Should Measure

For a generation, the nonprofit sector was governed by a single misleading number. Donors asked it, watchdogs ranked by it, and boards optimized for it: the overhead ratio, the percentage of a charity's budget spent on anything other than direct programs. The logic felt intuitive, a charity that spends more on programs and less on administration must be more efficient and more worthy. The problem is that the logic is wrong, and its wrongness has done real damage. In 2013, in an act almost without precedent, the leaders of the three major US charity-rating bodies, GuideStar, Charity Navigator, and the BBB Wise Giving Alliance, jointly published an open letter to the donors of America asking them to stop using overhead ratio as the primary measure of a nonprofit. They named the belief for what it was: a myth, and a destructive one. Understanding why is one of the most important things a nonprofit leader can carry into a board meeting.

What the Overhead Ratio Actually Measures, and Doesn't

The overhead ratio is the inverse of the program-expense ratio: it divides administrative and fundraising costs by total expenses. What it measures is real enough, where the money is categorized. What it does not measure is anything about whether the organization works. Two food banks can report identical overhead ratios while one feeds twice as many families per dollar, because the ratio is silent on outcomes entirely. Worse, the ratio is gameable: an organization can lower its reported overhead by misclassifying expenses, underpaying staff, or simply not spending on the evaluation and systems that would tell it whether its programs succeed. The number rewards the appearance of frugality, which is not the same thing as effectiveness, and frequently its opposite.

The Starvation Cycle

The most serious consequence of overhead obsession is a self-reinforcing trap the Bridgespan Group and the Stanford Social Innovation Review documented as the nonprofit starvation cycle. It runs like this: funders, conditioned to equate low overhead with efficiency, pressure organizations to minimize administrative spending. Organizations respond by underinvesting in, and underreporting, the staff, technology, training, and evaluation their missions actually require. Capacity erodes, programs quietly underperform for lack of infrastructure, and the organization, now genuinely weaker, faces even more pressure to keep overhead low. The cycle starves the very functions that would let a nonprofit prove and improve its impact, all in service of a number that was never a good measure of impact to begin with. An organization that cannot afford a development professional cannot build the fundraising that funds its mission, a connection we draw out in cost to raise a dollar by channel, where underfunded fundraising capacity directly raises the cost of every dollar raised.

Why a Very Low Ratio Can Be a Warning

Once you see the starvation cycle, a strikingly low overhead ratio stops looking like a badge and starts looking like a symptom. An organization spending almost nothing on management and fundraising is often an organization that cannot recruit experienced leaders, cannot afford the data systems that demonstrate outcomes, and cannot sustain the fundraising operation that brings in next year's revenue. There is no universal correct overhead percentage, and the long-cited benchmark around 25% to 35% was always more folklore than science. A young organization building capacity may legitimately run higher; a mature one may run lower; and neither number, by itself, tells a donor or a board anything reliable about whether the mission is being accomplished. The honest answer is that overhead ratio is simply the wrong instrument for the question everyone was using it to answer.

What to Measure Instead

If not overhead, then what? Sector leaders are consistent on the replacement: outcomes and capacity. What does the organization actually accomplish, and how does it know? Does it measure results rather than just activities? Is the leadership experienced and the board engaged in real oversight? Are the financials audited and transparent, and is the funding base diversified enough to survive a shock? These questions say vastly more about a nonprofit's health than the percentage it happened to spend on administration last year. Governance in particular is a far better signal than overhead, because a capable, engaged board is the structure that ensures resources are stewarded toward impact, the dimension a structured Board Governance Health Score is built to surface across composition, engagement, oversight, and succession. The strength of the board, not the thinness of the overhead line, is what predicts whether an organization will use its money well.

Changing the Donor Conversation

The practical work for a nonprofit leader is to stop defending overhead and start explaining capacity. When a donor asks about overhead, the unproductive response is an apology and a low percentage; the productive one reframes the line entirely, describing what that spending buys, the experienced program staff who make the work effective, the data systems that prove it worked, and the fundraising that brings in the next dollar to do it again. Donors increasingly respond to impact and transparency, and organizations that proactively educate their supporters on why infrastructure matters tend to win more unrestricted support, the most valuable and durable revenue there is, which we cover in the context of the overall nonprofit funding mix. The reframe also protects the organization's own decision-making: a board that internalizes the overhead myth stops cutting the capacity that drives results in order to flatter a ratio.

For the fundraising consultants, capacity-building firms, and nonprofit CRM vendors that help organizations build exactly this infrastructure, the overhead myth is the heart of the value proposition, because their work is the overhead a starved organization most needs and most fears to fund. Meeting an executive director who has internalized that capacity is an investment rather than a cost is a far warmer conversation than a cold proposal, the pattern documented on the lead generation tools for nonprofits page. For the nonprofit itself, the lesson the sector's own watchdogs delivered a decade ago still holds: judge an organization by what it achieves and how well it is run, never by how little it dares to spend on running itself.

Where the Overhead Number Comes From, and Why It Distorts

Part of the reason the overhead ratio carries such undeserved authority is that it is drawn from an official document, the IRS Form 990, which every larger tax-exempt organization files publicly. The 990 requires expenses to be allocated across three functional buckets: program services, management and general, and fundraising. The overhead ratio is simply the latter two divided by the total. The trouble is that the boundaries between these buckets are far blurrier than the clean percentage suggests, and the allocation involves real judgment. The salary of an executive director who spends half her time running programs and half managing the organization can be split many defensible ways, and two honest nonprofits doing identical work can report meaningfully different overhead ratios purely because of how they classify shared costs. Candid, which hosts the largest public repository of 990 data, has long cautioned that the functional-expense split is an accounting artifact, not a clean measure of efficiency, and that comparing the resulting ratios across organizations invites exactly the false precision the overhead myth thrives on.

This classification softness is also what makes the ratio gameable in the wrong direction. An organization under pressure to show low overhead can shift borderline costs into the program bucket, defer investment in the management and fundraising functions that would have landed in the other two, and emerge with a flattering number that reflects accounting choices and underinvestment rather than genuine efficiency. The reported ratio rewards the organization that classifies aggressively and starves quietly over the one that reports its true cost of operating honestly, which inverts the signal donors think they are reading. A board that wants a real efficiency picture has to go behind the 990 line to the actual capacity questions the number cannot see.

How the Conversation Shifted in 2025 and 2026

The decade since the 2013 open letter has not erased the overhead myth, but it has steadily eroded its grip, and the last two years accelerated that shift. Charity Navigator, once the loudest popularizer of overhead-based scoring, has restructured its ratings around impact and results alongside finance and accountability, an explicit move away from treating a low overhead ratio as the headline grade. The broader movement that grew out of the original letter, which pushed donors and funders toward outcomes over ratios, has moved from the conference stage into how a growing share of institutional funders actually write grants, with more of them funding full project costs and including genuine indirect-cost recovery rather than demanding artificially low overhead. The direction of travel across the sector is unmistakable: the question funders increasingly ask is what the organization accomplishes and how it knows, not how thin it can make its administrative line, and the nonprofits positioned best for the next funding cycle are the ones that have already stopped apologizing for the capacity their mission requires.
