A good overhead ratio for nonprofits generally falls between 15% and 35% of total expenses, with the most widely cited ceiling coming from the BBB Wise Giving Alliance: at least 65% of total spending should go to program activities, meaning overhead should stay at or below 35%.1BBB Standards for Charity Accountability. BBB Standards for Charity Accountability Where a specific organization should land inside that range depends on its size, age, and mission. And the three largest charity watchdogs in the country have publicly warned donors that overhead alone is a poor way to judge whether a nonprofit is doing its job.
How the Ratio Is Calculated
The overhead ratio divides a nonprofit’s indirect costs by its total functional expenses. Indirect costs fall into two categories that every Form 990 filer must report separately: management and general expenses, and fundraising expenses.2Internal Revenue Service. Form 990 – Part IX Statement of Functional Expenses
Management and general covers the back-office work of running the organization: salaries for finance and HR staff, office rent, insurance, legal fees, accounting, and IT systems. Fundraising covers everything involved in soliciting contributions: gala events, direct mail, donor database software, and any fees paid to outside fundraising consultants.
Add those two together and divide by total functional expenses, which include program costs plus all overhead. If an organization spent $700,000 on programs, $150,000 on management, and $150,000 on fundraising, total expenses are $1,000,000 and the overhead ratio is 30%.
The Benchmarks Donors and Watchdogs Use
The BBB Wise Giving Alliance frames its standard from the program side: a charity should spend at least 65% of total expenses on program activities, which puts the overhead ceiling at 35%.1BBB Standards for Charity Accountability. BBB Standards for Charity Accountability Many institutional donors and grant-making foundations look for ratios between 20% and 35% when reviewing applications. CharityWatch reserves its “highly efficient” label for organizations that keep overhead below 25%.
Charity Navigator, the largest independent charity evaluator, now uses a broader system called the Encompass Rating, which scores organizations across accountability and finance, impact and results, leadership and adaptability, and culture and community.3Charity Navigator. Ratings Financial efficiency remains part of the picture, but the overhead ratio no longer drives a charity’s star rating the way it once did.
Why the Ratio Alone Can Mislead
In 2013, the heads of Charity Navigator, GuideStar (now Candid), and the BBB Wise Giving Alliance signed a joint open letter urging donors to stop treating overhead as the primary measure of a nonprofit’s worth. Their line: “The people and communities served by charities don’t need low overhead, they need high performance.” Fixating on the ratio, they argued, starves organizations of the freedom to invest in staff, planning, and evaluation.
A nonprofit that refuses to spend on experienced staff, training, modern technology, or program evaluation can post a low overhead number while delivering mediocre results. An organization that invests in strong leadership, reliable financial systems, and serious outcome evaluations will carry higher administrative costs and is more likely to accomplish its mission. The ratio cannot tell the difference between wasteful bureaucracy and smart infrastructure.
A fuller picture comes from outcome-oriented measures: the number of people served and whether they achieved measurable goals, constituent and donor retention rates, staff retention, and whether the organization publicly reports its results. None of those show up in a single percentage.
What Legitimately Pushes the Ratio Up or Down
Several factors move overhead ratios in ways that have nothing to do with waste. Reading the number well means accounting for them.
Age. Newer nonprofits face front-loaded fundraising costs as they build a donor base and brand recognition from scratch. Those startup investments push the ratio upward in the early years and usually settle down as recurring revenue stabilizes.
Mission complexity. A university requires extensive administrative staff, compliance infrastructure, and facility maintenance. A local food bank operating from a donated warehouse does not. Medical research, mental health services, and international relief inherently need more robust management systems, which means higher overhead without any waste.
Budget size. Fixed costs like an annual audit, accounting software, or directors-and-officers insurance take a much larger share of a $200,000 budget than a $10 million budget. Small nonprofits routinely report overhead ratios of 30% to 40% simply because they lack economies of scale.
State audit requirements. Most states require nonprofits above a certain revenue threshold to submit an independent CPA audit with their charitable solicitation registration. Thresholds typically range from $500,000 to $2,000,000 in gross revenue, and the audit itself is an overhead expense the organization cannot avoid.
Executive compensation. An executive director’s salary is often one of the largest single line items in overhead. The IRS provides a safe harbor for reasonable compensation: if an independent, conflict-free board committee reviews comparable salary data, documents its reasoning, and approves the pay in advance, the compensation is presumed reasonable. Skipping that process invites excess-benefit-transaction penalties and public criticism.4Internal Revenue Service. Publication 557 – Tax-Exempt Status for Your Organization
Two Accounting Mechanics That Distort the Number
Joint Cost Allocation
When an activity serves both fundraising and programmatic purposes, part of its cost can be moved out of the fundraising column. A direct mail piece that asks for a donation and also educates the reader about a health issue is a joint activity. Under AICPA Statement of Position 98-2, a nonprofit can allocate some of the mailing cost to program services instead of counting the whole expense as fundraising, but only if three criteria are all met.
- Purpose. The organization must have evidence, such as board minutes or written instructions, that the activity was intended to carry out a program objective, not just raise money.
- Content. The material must include a call to action that motivates the audience to do something other than donate, such as getting screened for a disease or registering to vote.
- Audience. The mailing list cannot be selected solely based on recipients’ ability or likelihood to contribute. If the audience is just past donors, the activity is presumed to be fundraising.5Give.org. Charity Guidance – Joint Cost Allocation
If any one of those criteria fails, the entire cost is classified as fundraising. The BBB Wise Giving Alliance pays particular attention when more than half of a shared activity’s cost is booked as program services, and it may request marked-up copies of the materials showing exactly which portions count as program, fundraising, or administration. Aggressive joint cost allocation can make an overhead ratio look artificially low.
The Federal De Minimis Rate
Nonprofits that receive federal grants operate under a separate framework in the OMB Uniform Guidance. Organizations with a negotiated indirect cost rate recover overhead at that rate. Those without one can elect a de minimis rate of up to 15% of modified total direct costs, with no documentation required to justify it.6eCFR. 2 CFR 200.414 – Indirect Costs Federal agencies and pass-through entities cannot force a nonprofit to accept a rate lower than the de minimis rate unless a specific statute requires it.
Once elected, the de minimis rate applies to all federal awards until the organization negotiates a higher one. For nonprofits heavily funded by government grants, this effectively caps how much overhead they can recover from federal dollars, which squeezes administrative budgets in ways unrelated to efficiency.
Where the Ratio Comes From on the Form 990
The overhead ratio is not something organizations self-report as a single figure. It is derived from Part IX of Form 990, the Statement of Functional Expenses, which requires every dollar of spending to be allocated across program services, management and general, and fundraising columns.2Internal Revenue Service. Form 990 – Part IX Statement of Functional Expenses Shared costs like an executive director’s salary or utility bills must be reasonably split across the categories, and the organization needs records justifying those splits.
Every Form 990 is a public document. A tax-exempt organization must provide its three most recent annual returns to anyone who asks: in-person requests fulfilled immediately, written requests within 30 days, at no charge beyond reasonable reproduction and mailing costs.7Office of the Law Revision Counsel. 26 US Code 6104 – Publicity of Information Required From Certain Exempt Organizations and Certain Trusts Most people skip the formal request and use Candid or ProPublica’s Nonprofit Explorer, both of which host searchable, digitized filings going back years.
That accessibility is what makes the ratio so visible. Anyone with an internet connection can pull up a Form 990, find Part IX, and calculate the percentage. The number is easy to get. Reading it well takes the context around it.
