The overhead ratio tells you Less Than You Think.

For decades the most common question donors have asked about a charity is how much of each dollar goes to the programs. The answer is easy to calculate from the Form 990, easy to compare, and easy to put in a headline. It is also a weak measure of whether an organization is doing good work.

What the number measures

The overhead ratio divides spending on management and fundraising by total expenses. Management covers things like accounting, human resources, the executive director's time spent on administration, insurance, audits, and technology. Fundraising covers the cost of raising money.

These are not wasted dollars. An organization without an accountant cannot produce reliable financial statements. One that never invests in its staff will lose them. One with no fundraising capacity will depend on a handful of donors and collapse when one leaves.

How the ratio misleads

The ratio rewards organizations for underinvesting in exactly the capacities that make programs reliable. It also varies with accounting choices. Two organizations doing identical work can report different ratios depending on how they allocate shared costs such as rent or an executive's time.

It penalizes young organizations, which must build systems before they have scale, and organizations in fields where the work is inherently expensive to deliver or to fund. A food bank moving donated goods will look very different from an advocacy group or a small arts nonprofit, even if all three are well run.

Researchers and sector leaders have described the result as a cycle. Funders expect low overhead, organizations report low overhead, and the real costs of running the organization are hidden or unmet. Staff turnover rises and program quality suffers.

Better questions to ask

• What does the organization say it will accomplish, and how does it know whether it did?
• Can it show results for the last few years, in numbers and in specific accounts?
• Is its board independent, and does it follow basic governance practices?
• Is its revenue diversified, or does it depend on one source?
• Does it have enough reserves to survive a bad quarter?

When overhead is a real warning

None of this means cost does not matter. Very high fundraising costs relative to money raised, large payments to insiders, or management spending that grows much faster than programs are worth questioning. The point is not to ignore the ratio but to read it alongside everything else. A single number was never going to tell you whether an organization is effective.
