The overhead myth

There's a number people reach for instinctively when sizing up a charity: the percentage spent on administration. If it's low — say, 5% or 10% — the charity feels trustworthy. If it's high, alarm bells ring. This reflex is understandable, and it's almost entirely wrong.

But that reasoning collapses the moment you think about what admin actually pays for

The idea that overhead is waste, and that a good charity spends virtually everything on "the cause", has been called the overhead myth — a term popularised by researchers and nonprofit advocates in the United States but just as relevant in the UK. It persists because it feels logical: money not spent on programmes is money not helping anyone. But that reasoning collapses the moment you think about what admin actually pays for.

Staff training, financial controls, monitoring and evaluation, IT systems, governance, legal compliance — these are not bureaucratic luxuries. They are the infrastructure that lets a charity deliver anything at all. A domestic abuse service that can't afford a proper case-management system, or a food bank that has no one qualified to manage its accounts, is not more effective for being lean. It is more fragile, more likely to make mistakes, and harder to hold to account.

The Charity Commission, which regulates charities in England and Wales, is clear in its guidance that there is no rule saying overheads must be below a certain figure. Overhead ratios are not a metric the regulator uses to judge effectiveness. They are a metric donors invented, and then charities learned to game.

What the numbers actually show

When you look at a charity's accounts — which are public for any registered charity, searchable through the Charity Commission's online register — the key document is the trustees' annual report alongside the statement of financial activities. These split expenditure into broad categories: charitable activities (the work itself), fundraising costs, and governance or management costs. That last category is what most people call "admin".

The split looks simple, but it hides a great deal. Salaries, for instance, are often the largest single cost a charity faces — and how they're categorised depends entirely on what those staff do. A charity might employ a project manager whose time is split between running programmes and managing the organisation. Where does her salary land? That's a judgement call, and different charities make it differently, which means comparing overhead percentages across organisations is largely meaningless without knowing how each one classifies its spending.

Fundraising costs add another wrinkle. Charities that invest seriously in acquiring new donors — running campaigns, maintaining a direct-debit base, stewarding major donors — will show higher costs in the short term. But that investment typically generates far more income over time. A charity that refuses to spend on fundraising because it looks bad in the accounts is quietly defunding its own future.

There's also a scale effect. A small charity with one or two staff will almost always show higher overhead percentages than a large one, because fixed costs — insurance, accountancy, a basic website — don't shrink proportionally with income. The case for giving to small charities rests on many things, but a clean overhead ratio isn't reliably one of them.

How to read the accounts well

None of this means financial transparency doesn't matter — it absolutely does. But the questions worth asking are different from "what's the overhead percentage?"

Start with the trustees' annual report. This is where a charity explains what it set out to do, what it actually did, and how it knows whether it worked. A well-run charity will describe its intended impact, cite evidence for its approach, and reflect honestly on what didn't go well. Vague language, no mention of outcomes, no acknowledgement of difficulty: these are warning signs.

Then look at the balance sheet. Reserves — money held back from current spending — are often misread as hoarding. In fact, a charity with no reserves is one bad year away from closing. The Charity Commission expects trustees to hold a reasonable level of reserves and to explain their reserves policy. What's "reasonable" varies by the kind of work: a charity that funds multi-year research projects needs more cushion than one running weekly food parcels. If reserves seem unusually high, the trustees' report should explain why.

Fundraising costs deserve a look, too. A charity spending £1 to raise £10 is doing something different from one spending £1 to raise £1.50, and the accounts will usually let you work this out. The Chartered Institute of Fundraising's guidance encourages charities to report their return on fundraising investment — not all do, but many larger ones will.

The final question is one no spreadsheet answers: does this charity's approach make sense? Is there evidence — independent evaluation, peer-reviewed research, credible case studies — that what they do works? A charity can have immaculate accounts and a genuinely ineffective programme, and another can look messy on paper and be transformative on the ground. The Charity Commission's public register, a charity's own impact reports, and independent watchdogs like Giving What We Can or the Centre for Effective Altruism can all help you look past the numbers to the substance beneath.

Overhead ratios tell you something. They just don't tell you what most people think they do.
