The Overhead Ratio Is a Bad Measure, and Here Is What to Read Instead

Everything below about the overhead ratio problem comes from what actually happens rather than from what is supposed to.

What the ratio measures

The overhead ratio divides spending classified as administration and fundraising by total spending, producing a number that looks comparable and mostly is not. The classification depends on where an organisation draws the line between support costs and charitable activity, and that line is a judgement. Two organisations doing identical work can report very different ratios purely through how they allocate shared staff time and premises.

Accounting standards constrain this in most jurisdictions, but they leave considerable room for legitimate difference. A figure that varies this much with presentation cannot support the fine distinctions donors try to draw with it.

Why low is not necessarily good

Spending on finance systems, safeguarding, evaluation, training and management appears as overhead and is what stops organisations failing. An organisation reporting an unusually low ratio may be underinvesting in exactly the functions that protect the people it serves.

In the annual accounts, it may also be benefiting from donated premises or seconded staff, which flatters the ratio without reflecting any decision it made. Researchers have described the resulting dynamic as a starvation cycle, in which pressure to report low overheads produces genuinely weaker organisations. The pressure comes from donors, so this is a problem the sector cannot solve on its own.

Why high is not necessarily bad

Fundraising costs money, and an organisation investing in acquiring new donors will show a worse ratio while building future income. Growing organisations, those in start-up phase, and those working in expensive or dangerous environments all carry structurally higher support costs.

On the shop floor, research and advocacy organisations often show high ratios because their charitable activity does not look like service delivery in the accounts. A single year's figure is particularly misleading, since one large capital purchase or one grant timing difference distorts it. Three years of figures read together are far more informative than one year read closely.

What to read instead in the accounts

Most jurisdictions require registered charities to publish annual accounts, and those accounts contain considerably more than the headline ratios. The reserves policy tells you whether trustees have thought about resilience and how many months of operation they could sustain. The breakdown of income by source shows concentration risk, which is often the most serious threat a small organisation faces.

Related party transactions, disclosed in most reporting frameworks, show whether money flows to people connected to the board.

The auditor's or examiner's report is short, and any qualification in it is worth considerably more attention than a ratio.

What to read in the narrative

Trustee reports in most frameworks must describe activities and achievements, and the quality of that description is itself informative. Organisations that describe what did not work, what they stopped doing and what they learned are demonstrating a governance culture.

Over a funding cycle, specific outcomes with defined measurement are more credible than large numbers of people reached, which is usually a count of contacts. Consistency between years matters, and an organisation that quietly changes its headline metric has usually done so for a reason. None of this requires accounting knowledge, only the willingness to read fifteen pages.

A workable assessment

Confirm registration on the public register in the organisation's own country, which almost all jurisdictions maintain. Read the most recent accounts and the previous year's, focusing on income sources, reserves and the trustee report rather than ratios. Check the board composition for size, turnover and whether anybody there has experience of the issue rather than only of business.

Look for evidence that the organisation measures whether its work achieves anything, and treat vagueness there as significant. Then decide, accepting that no publicly available information will tell you whether the work is actually effective.

The takeaway

Read the reserves policy and the trustee report; the ratio tells you about the accountant, not the charity.

Unrestricted money is the most useful gift and the least satisfying to make.
