The nonprofit overhead myth

Key Takeaways

• In 2013, GuideStar, Charity Navigator, and BBB Wise Giving Alliance jointly published an open letter to the sector declaring the overhead ratio a poor and potentially harmful measure of nonprofit performance, an event now commonly referred to as the Overhead Myth.

• A low overhead ratio can reflect underinvestment in the systems, staff training, and infrastructure a nonprofit actually needs to deliver its mission effectively, not genuine efficiency.

• The overhead ratio says nothing about outcomes: whether the programs a nonprofit runs actually work, whether they reach the people they're meant to serve, or whether the organization is financially sustainable over time.

• Major charity evaluators have since shifted toward measuring results and impact alongside financial metrics, rather than treating the overhead percentage as a standalone score of organizational quality.

• None of this means overhead spending is unlimited or unaccountable; it means the ratio alone, without context about what that spending actually accomplishes, is not a reliable proxy for whether a nonprofit is well-run.

Two nonprofits report identical 15% overhead ratios. One has invested that money in staff training, a functioning donor database, and financial systems that catch errors before they become problems. The other has starved its infrastructure so badly that the same ratio reflects an organization running on outdated software and burned-out, underpaid staff. The ratio tells a donor nothing about which is which, and that gap is exactly what the sector's leading watchdog organizations publicly acknowledged over a decade ago.

Quick Answer: Is a low overhead ratio actually a sign of a well-run nonprofit?

• Not reliably. In 2013, GuideStar, Charity Navigator, and BBB Wise Giving Alliance jointly declared the overhead ratio a poor measure of nonprofit performance, since it says nothing about whether programs actually work.

• A very low overhead ratio can just as easily signal underinvestment in staff, training, and systems as it can signal genuine efficiency, since starving infrastructure spending also lowers the ratio.

• What matters more is program outcomes and organizational sustainability, measures that require more than a single expense ratio to evaluate meaningfully.

Where the "overhead myth" declaration came from

In 2013, three of the most influential charity evaluation and information organizations in the sector, GuideStar, Charity Navigator, and BBB Wise Giving Alliance, jointly published an open letter to donors addressing what they called the overhead myth: the belief that a low overhead ratio is, by itself, a meaningful indicator of a nonprofit's worthiness or effectiveness. The letter argued that an obsessive focus on this single ratio was actually causing harm across the sector, pressuring organizations to underinvest in exactly the infrastructure and talent needed to run effective programs, in order to keep a number low that donors had been trained to scrutinize above almost everything else.

Why a low ratio can actually reflect a problem

Overhead spending, the management and general costs plus fundraising costs tracked through functional expense allocation, funds real things: financial controls that prevent fraud and error, staff training that improves program quality, technology that makes operations more efficient, and the fundraising capacity that keeps the organization funded at all. A nonprofit that drives its overhead ratio artificially low by underpaying staff, skipping necessary training, or running on unreliable systems isn't necessarily more efficient; it may simply be under-resourced in ways that eventually show up as staff turnover, program quality problems, or a financial crisis the organization didn't have the infrastructure to see coming.

What the ratio genuinely doesn't measure

The overhead ratio says nothing about whether a nonprofit's programs actually achieve their intended outcomes, whether the population served is genuinely being reached and helped, or whether the organization has the financial reserves to survive an unexpected funding gap. Two organizations can post identical overhead ratios while one delivers measurably better outcomes and maintains healthier financial reserves than the other, and the ratio alone would never reveal that difference. This is precisely why major evaluators have shifted their frameworks toward incorporating outcome and impact measures alongside financial ratios, rather than treating the overhead percentage as a standalone score.

What a more complete picture actually includes

A fuller assessment of nonprofit effectiveness looks at program outcomes and evidence of impact, financial health indicators like months of operating reserve on hand, governance quality, and transparency about how the organization measures its own success, alongside, not instead of, reasonable financial stewardship. None of this means overhead spending should go unexamined; a genuinely excessive or poorly justified overhead ratio remains a legitimate concern. The point is that the ratio needs context, not that it's meaningless.

Frequently asked questions

Should nonprofits stop reporting their overhead ratio to donors?

Not necessarily; the ratio is still a data point donors reasonably want to see, and refusing to disclose it can itself raise concerns. The better approach is reporting it alongside program outcome data and a brief explanation of what the organization's overhead spending actually funds, giving donors the fuller context the ratio alone can't provide on its own, context the board's own financial narrative to stakeholders should reinforce.

Has the IRS Form 990 changed how it presents overhead-related figures in response to this shift?

Form 990 has long required functional expense reporting broken into program services, management and general, and fundraising, which is where an overhead ratio is typically calculated from, and which appears on the nonprofit's own Statement of Activities alongside the underlying revenue figures reported on the IRS Form 990 series. The form itself hasn't eliminated this breakdown, since it remains useful data; what's shifted is how thoughtful evaluators and donors interpret that data, moving away from treating it as a standalone effectiveness score.

What's a reasonable range for overhead spending, if the ratio isn't meant to be the sole measure?

There's no single universal benchmark that applies across every type and size of organization, since appropriate overhead varies significantly by mission, size, growth stage, and sector, factors that also determine how functional costs get allocated in the first place. Comparing an organization's ratio to similarly sized peers in the same subsector, and evaluating whether the spending correlates with genuine capacity and outcomes, is more meaningful than measuring against a single fixed percentage.
