The Nonprofit Overhead Myth: A Practical Guide for Funders and Boards

Definition

The nonprofit overhead ratio is the share of total annual expenses that a nonprofit reports as administrative (management and general) costs plus fundraising costs, expressed as a percentage. The remainder — program expenses — is the portion the watchdog narrative used to call “the work.” Historically, donors and rating agencies used overhead ratios above 25% as a signal of inefficiency. That framework has been formally rejected by the same watchdogs that helped create it, but it persists in board conversations, donor letters, and well-intentioned but uninformed coverage of nonprofit performance.

This guide covers why the overhead ratio misleads, what sector leaders now use instead, and how to communicate about real nonprofit costs with donors and boards. It is written for executive directors and development directors at mid-sized US nonprofits who still face overhead questions and want to handle them confidently and honestly.

The original framework

The overhead ratio became a fundraising and rating metric in the 1980s and 1990s, popularized by donor advice columns and adopted by early online watchdogs. The reasoning was intuitive: dollars spent on administration and fundraising are not dollars spent on the mission, so a smaller share spent on overhead means more impact per dollar.

Two assumptions made this framework appealing:

1. That program expenses and overhead expenses are clearly separable on financial statements
2. That low overhead causally produces better outcomes

Neither assumption survived empirical scrutiny.

Why the ratio misleads

The split is subjective

The boundary between “program” and “management and general” on the IRS Form 990 is established by FASB ASC 958 (and earlier accounting standards) and is far more flexible than donors assume. Two nonprofits doing identical work can report dramatically different overhead ratios based on choices about:

• How to allocate the executive director’s time across programs and administration
• How to allocate office space, technology, and shared services
• How to categorize program staff who also do fundraising
• How to count earned revenue costs (a nonprofit running a thrift store might count store operations as program, administrative, or other)
• How to handle indirect cost allocations

A nonprofit aggressively allocating shared costs to programs can show a 10% overhead ratio. The same nonprofit, conservatively allocating, might show 30%. Neither is dishonest; both follow accepted accounting practice. The ratio is therefore meaningless for cross-organization comparison without forensic accounting work that no donor or board member is going to do.

For more on the accounting framework, see the FASB ASC 958 nonprofit reporting guide.

Low overhead does not predict outcomes

Research from Indiana University, Stanford, and the Bridgespan Group through the 2010s repeatedly found no correlation between low overhead ratios and program effectiveness. Some of the most effective nonprofits in their sectors had overhead ratios in the 25% to 40% range. Some of the least effective had ratios below 15%. Effectiveness correlates with organizational capacity, leadership quality, program design, and strategy — none of which the overhead ratio measures.

The starvation cycle

The strongest critique came from a 2009 paper by Ann Goggins Gregory and Don Howard at Bridgespan, identifying the “nonprofit starvation cycle”:

1. Donors and watchdogs pressure nonprofits to keep overhead low
2. Nonprofits under-invest in infrastructure — financial systems, technology, fundraising, professional development, leadership succession
3. Under-invested nonprofits become less effective and more financially fragile
4. Less effective and fragile nonprofits appear less worthy of investment
5. Pressure to keep overhead low intensifies, deepening the cycle

The research suggested that healthy nonprofit infrastructure investment often runs 25% to 35% of total expenses, not the 15% that watchdog narrative implied. Organizations that consistently underinvested in this layer were more likely to fail when stressed.

The 2013 sector reset

In June 2013, the three major US nonprofit watchdogs — GuideStar (now Candid), BBB Wise Giving Alliance, and Charity Navigator — jointly published an open letter titled “The Letter to the Donors of America.” The letter explicitly stated:

“The percent of charity expenses that go to administrative and fundraising costs — commonly referred to as ‘overhead’ — is a poor measure of a charity’s performance.”

The letter went further, calling on donors to evaluate nonprofits on transparency, governance, leadership, and results. Each of the three organizations subsequently revised their rating frameworks. Charity Navigator’s current methodology, for example, includes accountability and transparency factors, beacons for results reporting, and culture-and-community indicators alongside (and increasingly above) financial efficiency metrics.

The 2013 letter is now eight years old in the sense that matters most: every major US sector body, including the National Council of Nonprofits, GivingUSA’s institutional partners, and BoardSource, has formally moved past the overhead ratio. But the metric persists in popular discourse, in some board cultures, and in donor communications, especially among older donors trained on the original framework.

What funders actually use now

Sophisticated funders evaluate organizational effectiveness through several lenses:

Impact and outcomes — what changed for the population served, expressed as measurable indicators with baseline and target. The shift toward “trust-based philanthropy” emphasizes funder confidence in the organization’s theory of change and outcomes data, not financial efficiency.

Financial health indicators — months of operating reserves, debt service ratios, revenue diversification, audit findings (or absence). A nonprofit with 6 months of operating reserves and clean audits for 3 consecutive years signals capacity that the overhead ratio cannot measure.

Governance and leadership — board composition, executive compensation set through documented review, succession planning, conflict of interest policies, whistleblower protections.

Transparency — public availability of financials, annual reports, governance documents, and outcomes data.

Capacity for the work — staff expertise, infrastructure investment, learning culture, willingness to innovate. Funders increasingly fund “general operating support” precisely because they recognize that program effectiveness depends on infrastructure that overhead-focused funding cannot build.

How to talk to donors and boards

The conversation about overhead still happens. Handle it directly.

With an individual donor

A donor who asks about your overhead ratio is usually doing what they were trained to do. They want to know that their gift will be used responsibly. Acknowledge the underlying concern, share your number transparently, and redirect:

“Our overhead ratio is around X%, which we report transparently in our audited financials. The more meaningful number is what we accomplish per dollar invested — last year we served Y participants, achieved Z measurable outcomes, and produced $W in independently estimated economic impact. We invest carefully in financial controls, technology, and fundraising staff because organizations that underinvest in those areas tend to produce worse outcomes for the populations they serve, not better.”

Then offer the donor specific outcomes data and a path to a deeper conversation. The goal is not to win the abstract argument about ratios; it is to redirect attention toward the metrics that actually predict impact.

With a board member

A board member raising overhead concerns is often doing fiduciary diligence — and that diligence is welcome. The conversation can be more substantive than with a donor. Offer the board:

• A summary of the overhead myth research with citations
• Your organization’s overhead ratio in context (year over year, peer comparison if available, allocation methodology)
• The financial health indicators that better predict sustainability — operating reserves, revenue concentration, audit quality
• A direct discussion of where you think the organization should invest more, not less, in administrative or fundraising capacity

A board that understands the overhead myth becomes a board that supports investment in fundraising, technology, and operations. A board that does not becomes a board that pushes the organization deeper into the starvation cycle.

With a foundation funder

Most sophisticated foundations no longer ask about overhead ratios; if they do, the question often functions as a screening signal about the organization’s financial literacy. Answer the question, share context, and offer the funder the metrics they actually need to evaluate effectiveness — outcomes data, financial sustainability indicators, leadership stability.

In your case for support

Your case for support should not foreground the overhead ratio. If you address it, address it the way you would address any common misconception — directly and with redirect. The bulk of the case should focus on outcomes, organizational capacity, and the specific opportunity you are asking the donor to fund.

What this looks like in practice

A working approach for a $5M nonprofit:

1. Calculate and disclose your overhead ratio honestly. Use accepted accounting practice; avoid aggressive program allocations to game the ratio. Publish it in your annual report and on your website.

2. Invest deliberately in infrastructure. Budget for adequate financial controls, fundraising staff, technology, and professional development. Track infrastructure investment as a leading indicator of capacity, not a lagging cost to minimize.

3. Lead with outcomes in donor and board communication. Train staff and board members to redirect overhead conversations toward impact data, financial health indicators, and capacity.

4. Educate your board annually. Include a 30-minute board education session on the overhead myth, the starvation cycle, and the financial health indicators that actually matter. Repeat every two to three years as board composition changes.

5. Track financial health indicators. Operating reserves, revenue concentration, audit quality. Report these to the board quarterly alongside fundraising metrics.

The work is patient — overhead is a deeply rooted framework in popular discourse, and individual conversations will not displace it. But every donor and board member who shifts to outcomes-and-capacity thinking strengthens the ground on which the next development director, executive director, and board chair will build.

Frequently asked questions

What is the nonprofit overhead ratio?

The overhead ratio is the percentage of total expenses spent on administrative (management and general) and fundraising costs, as opposed to program costs, as reported on IRS Form 990. Historically, watchdogs and donors used a cutoff of 15% to 25% as a quality benchmark, with anything higher considered inefficient. The metric has been formally rejected by the major US sector watchdogs since 2013, but it persists in popular discourse, board conversations, and some donor literature.

Why is the overhead ratio considered misleading?

Three reasons. First, the ratio rewards organizations for under-investing in essential infrastructure — accounting, technology, fundraising, leadership development — which damages long-term effectiveness. Second, the program-vs-overhead split on Form 990 is highly subjective; two organizations doing identical work can report wildly different ratios depending on accounting choices. Third, the ratio measures inputs (cost allocation), not outcomes (impact); two organizations with identical 15% overhead ratios can produce vastly different results per dollar spent.

What replaced the overhead ratio?

Since 2013, the major US sector organizations — GuideStar (now Candid), BBB Wise Giving Alliance, and Charity Navigator — have promoted a more nuanced framework focused on impact, transparency, governance, and financial sustainability. Charity Navigator’s current rating system explicitly de-emphasizes the overhead ratio in favor of multiple factors. Funders increasingly evaluate organizational effectiveness through outcomes data, financial reserves, leadership stability, and program design quality.

What is the “starvation cycle” in nonprofit funding?

The starvation cycle is a self-reinforcing pattern, identified by researchers at Indiana University and Stanford in the early 2010s, where pressure to keep overhead low forces nonprofits to under-invest in infrastructure (accounting, technology, fundraising, training), which then makes them less effective and more financially fragile, which then makes them appear less worthy of investment, which compounds the underinvestment. Research suggests that healthy nonprofit infrastructure investment often runs 25% to 35% of expenses, not 15%.

How should we talk to donors and board members about overhead?

Acknowledge the question directly, explain why the ratio misleads, and redirect to outcomes. A useful framing: “Our overhead ratio is X%, which we report transparently. The more useful question is what we accomplished per dollar — Y participants served, Z outcomes achieved, $W in measurable economic impact. We invest in strong financial controls, technology, and fundraising because organizations that under-invest in infrastructure produce worse outcomes for the populations we serve.”
