Nonprofit Overhead Ratio
The overhead ratio — the share of spending that goes to administration and fundraising rather than programs — is one of the most widely cited metrics in the nonprofit sector. It is also one of the most misunderstood. Here is what it actually measures, where it comes from on Form 990, and why a fixation on low overhead can do more harm than good.

Key Takeaways
The overhead ratio is total administrative and fundraising expenses divided by total expenses, derived from Form 990 Part IX.
The IRS does not set a maximum overhead ratio — there is no regulatory threshold that determines whether a nonprofit's overhead is acceptable.
In 2013, GuideStar, Charity Navigator, and the BBB Wise Giving Alliance jointly denounced overhead ratio as the sole measure of nonprofit performance.
Chronically low overhead often signals underinvestment in infrastructure, staff, and systems — a pattern known as the nonprofit starvation cycle.
Effective evaluation looks beyond overhead to transparency, governance, measurable outcomes, and financial sustainability.
What Is the Overhead Ratio?
The most cited — and most misused — metric in the nonprofit sector.
The overhead ratio is the percentage of a nonprofit's total expenses that goes to administrative and fundraising costs rather than direct program services. It is calculated from the functional expense categories reported on IRS Form 990 Part IX, which requires Section 501(c)(3) and 501(c)(4) organizations to allocate every dollar of spending across three columns: program services, management and general, and fundraising. [1]
The inverse of the overhead ratio is the <a href="/nonprofits/resources/nonprofit-program-vs-administrative-expenses">program expense ratio</a> — the share of spending that goes directly to mission-related work. A nonprofit with a 25% overhead ratio has a 75% program expense ratio. Both metrics come from the same Form 990 data, and evaluators use them interchangeably depending on whether they want to frame the number positively or negatively.
Overhead Ratio
The percentage of total expenses spent on management & general costs plus fundraising costs. Calculated as (Management & General + Fundraising) / Total Expenses. Reported on Form 990 Part IX, Line 25, using Columns C and D divided by Column A.
Program Expense Ratio
The percentage of total expenses spent directly on program services. Calculated as Program Service Expenses / Total Expenses. Reported on Form 990 Part IX, Line 25, Column B divided by Column A. The complement of the overhead ratio.
How the Overhead Ratio Is Calculated
Three expense categories, one formula.
Every dollar a nonprofit spends falls into one of three functional categories defined by GAAP (ASC 958) and reported on Form 990: [1] [2]
The Three Functional Expense Categories
Program Services
Direct costs of delivering the organization's mission — staff running programs, supplies for beneficiaries, grants distributed, facility costs tied to service delivery.
Management & General
Administrative costs necessary to run the organization — executive office, accounting, HR, legal, board governance, information technology, and general office operations.
Fundraising
Costs of soliciting contributions and grants — fundraising staff salaries, direct mail campaigns, events, donor management systems, and professional fundraising fees.
The Formula
Overhead Ratio = (Management & General Expenses + Fundraising Expenses) ÷ Total Expenses. For example, if a nonprofit spends $800,000 on programs, $120,000 on administration, and $80,000 on fundraising, its overhead ratio is ($120,000 + $80,000) ÷ $1,000,000 = 20%.
Many costs span multiple categories. Staff salaries, rent, and technology are often split across program, administrative, and fundraising functions. The IRS allows reasonable allocation methods, including time-and-effort studies, square footage, and headcount. This flexibility means that two organizations with identical operations could report different overhead ratios depending on their allocation methodology. [2]
Where It Appears on Form 990
Part IX: Statement of Functional Expenses.
<a href="/nonprofits/resources/how-to-read-form-990">Form 990</a> Part IX is the source document for overhead ratio calculations. All Section 501(c)(3) and 501(c)(4) organizations that file Form 990 must complete the full functional expense breakdown. Organizations filing Form 990-EZ (gross receipts under $200,000 and assets under $500,000) are not required to report functional expense allocations. [1]
Part IX Structure
Column (A): Total expenses across all categories.
Column (B): Program service expenses — direct mission delivery costs.
Column (C): Management and general expenses — administrative overhead.
Column (D): Fundraising expenses — costs of raising money.
Line 25: Total functional expenses — the bottom line for each column.
Line 26: Joint costs — for organizations using joint cost allocation under ASC 958-720.
Part IX includes roughly 25 line items covering grants, compensation, professional fees, occupancy, travel, depreciation, insurance, and other expenses. Each line must be allocated across the three functional columns. The totals on Line 25 are what evaluators like Charity Navigator and GuideStar use to calculate overhead and program expense ratios. [1]

Common Benchmarks
What the major evaluators say — and what they don't.
There is no universal overhead ratio standard. The IRS does not set a maximum, and the major nonprofit evaluators each use different thresholds. Here is what the most cited sources recommend: [3] [4] [5]
Major Evaluator Standards
Charity Navigator
Gives full credit to organizations with a program expense ratio of 70% or more (overhead of 30% or less). However, Charity Navigator states that it sees 'no evidence that a program expense ratio of greater than 70% leads to greater impact.' The program expense ratio now accounts for as little as 2% of an organization's overall rating. [3]
BBB Wise Giving Alliance
Requires that at least 65% of total expenses go to program activities, and that fundraising expenses not exceed 35% of related contributions. BBB uses audited financial statements rather than Form 990 for its evaluations. [4]
OMB Uniform Guidance
For federal grant recipients, the de minimis indirect cost rate was raised from 10% to 15% of modified total direct costs in the 2024 revision. Organizations can also negotiate a higher rate based on actual costs. [5]
No Single 'Right' Number
The right overhead ratio depends on an organization's mission, size, geography, and growth stage. A food bank distributing donated goods will have a very different cost structure than a legal aid clinic staffed by attorneys. Research shows the typical range for most nonprofits is 20% to 35%. [6]
Research from Hung, Berrett, and Ma (2025) found that donor sensitivity to overhead varies significantly by subsector. Donations to human service nonprofits decrease substantially when overhead reaches 35%, whereas donations to health care nonprofits do not decrease until overhead reaches 50%. There is no one-size-fits-all threshold. [7]
The Overhead Myth
The landmark 2013 campaign that changed how the sector thinks about overhead.
In June 2013, the CEOs of GuideStar, Charity Navigator, and the BBB Wise Giving Alliance — the three most influential charity evaluators in the United States — published a joint open letter to donors denouncing the use of overhead ratio as the primary measure of nonprofit effectiveness. [8]
“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.”
— GuideStar, Charity Navigator, and BBB Wise Giving Alliance (2013)
The letter argued that overhead costs include critical investments in training, planning, evaluation, internal systems, and fundraising capacity — all of which are necessary for organizations to deliver results. The campaign, branded as the #OverheadMyth, urged donors to focus on transparency, governance, leadership, and measurable outcomes instead. [8]
In October 2014, the same three organizations issued a follow-up letter directed at charities themselves, urging them to help crush the overhead myth by demonstrating ethical practices, managing toward results, and educating funders about the true costs of impact. [9]
Key Points from the Overhead Myth Campaign
Lower overhead does not mean greater effectiveness. There is no evidence linking low overhead to better outcomes.
Overhead includes essential investments — accounting, technology, staff development, compliance, and fundraising infrastructure.
Donors should evaluate charities on transparency, governance, and results rather than a single financial ratio.
Focusing exclusively on overhead creates perverse incentives to underreport costs and underinvest in organizational capacity.
The Nonprofit Starvation Cycle
How the fixation on low overhead undermines the organizations donors want to support.
In 2009, Ann Goggins Gregory and Don Howard published a landmark article in the Stanford Social Innovation Review identifying what they called the nonprofit starvation cycle — a self-reinforcing pattern in which donor pressure to minimize overhead leads to chronic underinvestment in organizational infrastructure. [10]
How the Starvation Cycle Works
Donor Pressure
Funders demand low overhead ratios, sometimes capping indirect costs at 10-15%.
Underinvestment
Nonprofits cut spending on technology, training, financial systems, and competitive salaries to meet funder expectations.
Underreporting
Organizations use accounting flexibility to shift overhead costs into program categories, making reported ratios artificially low.
Unrealistic Expectations
Donors see the artificially low numbers and expect even lower overhead from other organizations.
Organizational Decline
Without adequate infrastructure, nonprofits struggle with staff burnout, poor data systems, and inability to measure or improve their impact.
Research on Overhead Underreporting
A 2025 study by Kim, Charbonneau, and Sowa found that nonprofit managers routinely underreport overhead by 7 to 16 percentage points to appear more efficient to donors. This suggests that actual overhead rates across the sector are considerably higher than what Form 990 filings show. [11]
The Bridgespan Group has documented that this cycle particularly harms mid-size nonprofits trying to scale. Organizations that need to invest in systems, talent, and evaluation to grow are penalized by funders who equate overhead with waste. Five major foundations — Ford, Hewlett, MacArthur, Open Society, and Packard — have publicly acknowledged this problem and committed to increasing overhead funding for their grantees. [12]
What Donors Should Look For Instead
Moving beyond a single number to meaningful evaluation.
If overhead ratio is a poor proxy for effectiveness, what should donors and board members evaluate? The experts who dismantled the overhead myth recommend a more holistic approach to <a href="/nonprofits/resources/how-to-evaluate-a-nonprofit">evaluating nonprofits</a>: [8] [9]
Five Better Indicators of Nonprofit Health
Transparency
Does the organization openly share financial statements, Form 990s, strategic plans, and outcome data? Organizations with nothing to hide make information easy to find.
Governance
Is there an active, independent board with proper oversight? Look for conflict-of-interest policies, regular board meetings, and clear separation between governance and management.
Measurable Outcomes
Can the organization demonstrate what it has achieved? Look for specific metrics, evaluation reports, and evidence of program effectiveness — not just activity counts.
Financial Sustainability
Does the organization have diversified revenue, adequate reserves, and a realistic budget? A nonprofit with a 10% overhead ratio but three months from insolvency is not a good investment.
Strategic Investment
Is the organization investing in the people, technology, and systems it needs to deliver results? Reasonable overhead often indicates an organization that is building capacity to increase impact.
Charity Navigator's Evolution
Reflecting the shift in thinking, Charity Navigator updated its methodology so that the program expense ratio accounts for as little as 2% of a charity's overall rating. The majority of the score now comes from accountability, transparency, leadership, and impact measures. [3]
Best Practices for Nonprofits
How to manage, report, and communicate about overhead effectively.
Nonprofits cannot control donor perceptions overnight, but they can take concrete steps to manage overhead responsibly and communicate about it effectively.
Overhead Management Checklist
Use a consistent, defensible methodology for allocating costs across functional categories (time studies, square footage, headcount).
Follow GAAP (ASC 958) and IRS instructions for functional expense reporting on Form 990 Part IX.
If you receive federal funding, negotiate a federally negotiated indirect cost rate (NICRA) rather than accepting the de minimis 15% rate if your actual costs are higher. [5]
Invest in the infrastructure your organization needs — technology, training, competitive salaries, and financial systems — even if it increases your overhead ratio.
Proactively explain to donors and funders what overhead costs pay for and how they support the mission.
Include overhead costs in grant proposals and budgets. Do not absorb indirect costs that should be funded.
Conduct an annual review of functional expense allocations to ensure they accurately reflect how resources are being used.
Communicate the Value of Overhead
The National Council of Nonprofits recommends framing overhead as 'investing in impact.' When a donor asks why overhead is 25%, explain what that 25% funds: the accounting system that ensures every dollar is tracked, the IT infrastructure that keeps programs running, the staff training that improves service delivery. [13]
Common Mistakes
Pitfalls to avoid when managing and evaluating overhead.
Mistakes Nonprofits Make
Artificially Suppressing Overhead
Shifting administrative costs into program categories to appear more efficient. This misrepresents the organization's finances and can create compliance issues. [11]
Underinvesting in Infrastructure
Cutting spending on technology, training, and competitive compensation to keep overhead low. This leads to staff burnout, high turnover, and declining organizational capacity. [10]
Absorbing Indirect Costs
Failing to include overhead in grant budgets, effectively subsidizing restricted grants with unrestricted funds.
Ignoring Joint Cost Allocation
Not properly allocating joint costs (e.g., a direct mail piece that both solicits donations and educates about the mission) under ASC 958-720. Proper allocation can more accurately reflect the program component of multi-purpose activities. [1]
Mistakes Donors and Funders Make
Using Overhead as the Primary Metric
Treating overhead ratio as a proxy for effectiveness without evidence that lower overhead leads to better outcomes. [8]
Capping Indirect Cost Rates
Imposing overhead caps of 10-15% that bear no relationship to actual costs, forcing organizations to underinvest or misreport. [12]
Comparing Across Sectors
Expecting a research institute and a food bank to have the same overhead ratio. Cost structures vary dramatically by mission, geography, and organizational stage. [7]
Penalizing Growth
Organizations investing in capacity to scale will often see temporary overhead increases — this is a sign of strategic investment, not waste.
