The overhead ratio myth: does 'how much goes to the cause' actually matter?

The public wants most donations to reach the cause. Sector leaders say overhead ratios are misleading. Both are right — and the gap between them shapes how charities operate, invest, and communicate.

By Tom Neill-Eagle

The debate in brief

The proportion of donations that reaches "the cause" is the single most important factor in whether the British public trusts a charity. In the Charity Commission's 2025 public trust research, 53% of respondents cited it as their top concern. Charities know this, and many shape their messaging around low overheads accordingly.

But almost every serious analyst of the charity sector considers overhead ratios a poor, and sometimes dangerous, measure of effectiveness. A charity spending 5% on administration might be neglecting the staff training, financial systems, and evaluation that make its work any good. A charity spending 25% might be investing wisely in the infrastructure that delivers better outcomes. The ratio tells you almost nothing about whether anyone is actually being helped.

This gap between what donors want to hear and what the evidence says creates a vicious cycle. Charities underspend on the things that would make them more effective, then present that underspending as a virtue. And the public, given no better metric, keeps asking the wrong question.

Common questions

What is a good overhead ratio for a charity?

There is no universal "good" overhead ratio, and setting one would be misleading. Academic research published in Nonprofit and Voluntary Sector Quarterly in 2022 found an inverted U-shaped relationship between overhead spending and programme outcomes: cutting overhead too far actually compromises results, while investing in it up to an optimal point improves them. The optimal levels identified — around 35 to 43% depending on programme type — are far higher than the single-digit figures many donors assume are virtuous. The Charity Commission has deliberately not set a prescribed ratio, focusing instead on whether spending is proportionate and transparent.

How much of my donation actually goes to the cause?

According to the NCVO UK Civil Society Almanac 2024, 80% of voluntary sector spending in 2021/22 went directly on charitable activities — consistent across organisation sizes from micro charities (78%) to the largest organisations (83%). The ICAEW cites a similar figure of 86% for expenditure directly linked to charitable purpose. But the more important question is whether that spending is achieving anything: a charity directing 90% of income to programmes that do not work delivers less value than one investing 70% in well-evidenced, well-run services.

What is the charity starvation cycle?

The nonprofit starvation cycle was named by Ann Goggins Gregory and Don Howard in the Stanford Social Innovation Review in 2009. It describes a self-reinforcing loop: funders set unrealistically low expectations for overhead costs; charities respond by underspending on infrastructure and underreporting their true costs; this apparent frugality then reinforces funders' expectations, and the cycle repeats. The consequences are tangible — charities skimp on technology, staff development, and evaluation, precisely the capabilities that would make their work more effective. Dan Pallotta described this as an "economic apartheid", where charities are denied the organisational investment that businesses use freely.

Should I check a charity's admin costs before donating?

Looking at admin costs in isolation is unlikely to tell you much that is useful. There is no consistent definition of "overhead" or "administration" across charity accounts, making comparisons unreliable. More useful questions are: what outcomes does the charity achieve, and is there evidence it works? Is it transparent about its costs and the challenges it faces? Has it been evaluated by independent researchers or funders? Three of the world's largest charity rating organisations — GuideStar, Charity Navigator, and the BBB Wise Giving Alliance — issued a joint letter in 2013 explicitly warning donors against using overhead ratios as a primary measure, stating that "the people and communities served by charities don't need low overhead, they need high performance."

Why do charities keep talking about how little they spend on admin?

Because it works, at least in the short term. The Charity Commission's 2025 public trust research found that the proportion of donations reaching "the cause" is the single most important factor in whether the British public trusts a charity, cited by 53% of respondents. Charities know this, and many shape their messaging accordingly — even when it means presenting artificially low overheads as a virtue. The result is a collective action problem: individual charities have an incentive to compete on low overheads even though the sector as a whole would be better served by investing in the infrastructure that actually improves outcomes.

The arguments

The case for scrutinising how charities spend

The instinct behind the overhead question is not unreasonable. Donors are entrusting their money to organisations they cannot directly oversee, and wanting to know it is being used well is a basic expression of accountability. There are genuine cases of charities with bloated administration, excessive executive pay, or fundraising costs wildly out of proportion to their income. The Charity Commission exists in part because the public needs confidence that charitable funds are properly managed.

Overhead ratios, for all their flaws, are one of the few pieces of financial information that are readily available and broadly comparable. When the Charity Commission's 2025 research found that 64% of people believe the charities they know about are maximising spend on the end cause — up seven points on the previous year — that reflected a genuine interest in financial stewardship. Removing scrutiny entirely would risk eroding the public accountability that underpins charitable status.

The case that overhead ratios are misleading

The intellectual consensus among charity analysts is stark. New Philanthropy Capital described the trend of judging charities by their overhead spending as "misleading — dangerous, even." Iona Joy, then NPC's head of charity effectiveness, put it plainly: "Overhead cost is not a predictor of what a charity can achieve."

In June 2013, three of the largest charity rating organisations in the world — GuideStar, Charity Navigator, and the BBB Wise Giving Alliance — took the unusual step of issuing a joint open letter declaring that overhead ratios are "a poor measure of a charity's performance." Their message was direct: "The people and communities served by charities don't need low overhead, they need high performance."

The problems are both technical and substantive. On the technical side, there is no consistent definition of "overhead" or "administration costs" across charity accounts, making comparisons between organisations unreliable. On the substantive side, academic research has found no meaningful correlation between low overhead ratios and better outcomes. A 2022 study published in Nonprofit and Voluntary Sector Quarterly found an inverted U-shaped relationship: cutting overhead below a certain threshold actually compromises programme outcomes. The optimal overhead levels identified in the research — around 35 to 43% depending on programme type — are far higher than what most donors would consider acceptable.

The starvation cycle

Between these two positions sits a structural problem that Ann Goggins Gregory and Don Howard named in the Stanford Social Innovation Review in 2009: the nonprofit starvation cycle. Funders set unrealistic expectations about overhead costs. Charities respond by underspending on infrastructure and underreporting their true costs. This apparent frugality then reinforces funders' unrealistic expectations, and the cycle repeats.

The consequences are tangible. Charities skimp on technology, staff development, and evaluation — the very capabilities that would improve their effectiveness. Dan Pallotta, whose 2008 book Uncharitable and 2013 TED talk brought this argument to a mainstream audience, argued that the sector operates under an "economic apartheid" — denied the tools that businesses use freely, because donors hold charities to a different moral standard on spending.

The evidence

According to the NCVO UK Civil Society Almanac 2024, 80% of voluntary sector spending in 2021/22 went directly on charitable activities, with 10% on grants to other organisations and 10% on generating funds. This pattern held across organisation sizes, from micro charities (78%) to the largest organisations (83%). The ICAEW, drawing on slightly different NCVO data, cites 86% of sector expenditure going to activities directly linked to charitable purpose.

The Charity Commission's Public Trust in Charities 2025 report found that trust remains high and stable, with an average trust score of 6.5 out of 10. Despite this, 19% of people who do not give to charity cite a lack of trust in how charities use money as their reason, according to the CAF UK Giving Report 2025. Only inability to afford donations (44%) is a more common barrier.

NCVO's 2023 True Cost of Delivering Public Services survey revealed a related dimension of the problem: 87% of charities delivering government-funded services are subsidising those contracts from other income. NPC's State of the Sector 2024 report estimated this subsidy at £2.4 billion per year. When funders — including government — refuse to pay the true overhead cost of delivery, charities cross-subsidise from voluntary income, gradually hollowing out their own sustainability.

The IZA World of Labor, reviewing the international evidence base, concluded that overhead cost ratios are "a crude measure that does not adequately evaluate effectiveness" — but also noted that field experiments show donors give more when told a separate donation covers administrative costs. The concern is real even if the metric is flawed.

One genuinely surprising finding from Altamimi and Liu's research: increased spending on overhead actually improves programme outcomes up to an optimal point far higher than donors expect. Cutting overhead below that threshold compromises results. Low overhead is not a sign of efficiency. It may be a sign of underinvestment.

Current context

The overhead debate is shifting, slowly. The trust-based philanthropy movement is gaining ground internationally, with more than 135 US grantmakers signing commitments in 2025 to provide more flexible, unrestricted funding. In the UK, the shift is visible in funder practice: multi-year, unrestricted grants are becoming more common, and organisational capacity is increasingly recognised as a legitimate outcome of philanthropic investment.

At the same time, the UK charity sector faces a severe financial squeeze. The CAF Charity Insights Report 2025, based on feedback from 549 charity leaders, found that less than a third (30%) of charity leaders think the sector is in a healthy position, with 44% citing cost rises as a main challenge. The employer National Insurance Contribution increase, estimated by NCVO at £1.4 billion in additional costs for the sector, has intensified pressure on charities already running on thin margins. In this climate, the temptation to cut "overhead" first — because it is the most politically palatable cut — is strong and damaging.

The Charity Commission has not set prescribed overhead ratios, and its revised CC20 fundraising guidance (published February 2026) focuses on proportionality and transparency rather than specific spending thresholds. But the regulator's own research shows that public trust still hinges on the perception that donations reach the frontline. The gap between what the evidence says and what donors feel remains wide.

What this means for charities

Charity leaders face a genuine strategic tension. The evidence says you should invest in your organisation's infrastructure, systems, people, and evaluation capability. The public — and many funders — will judge you for doing so. Navigating this requires both courage and communication.

The charities that handle this best tend to do three things. First, they know their actual costs and can explain them — a charity that understands its full cost recovery position can negotiate honestly with funders. Second, they talk about what their spending achieves rather than how little they spend. "We invest in training our frontline workers because it leads to better outcomes" is a stronger message than "95% goes to the cause." Third, they refuse to participate in the race to the bottom — recognising that presenting artificially low overheads is not a competitive advantage but a collective harm.

The overhead question will not go away, because the public impulse behind it — wanting donations to make a difference — is legitimate. The task is to redirect that impulse from a misleading metric toward a meaningful conversation about effectiveness.
