“How much of my donation goes to the cause?” and “what percentage of donations goes to administration?” are the questions UK donors ask most often — usually right before they give, or after seeing a headline about charity CEO pay or overheads.
The useful answer is not a single magic percentage. It is cause spend from UK regulator filings, read in context of the charity’s model, then checked alongside reserves, fundraising costs and filing record.
What “money to the cause” actually means
UK charity accounts split expenditure into standard headings:
- Charitable activities — spending that delivers the purpose: research grants, hospice beds, food parcels, animal rescue, advice lines, teaching.
- Raising funds — fundraisers’ salaries, direct mail, digital ads, lottery costs, charity-shop running costs.
- Support and governance — finance, HR, IT, safeguarding, audit and trustee expenses.
The figure people mean by “percentage to the cause” is charitable activities ÷ total expenditure. On CharityCompare that appears as cause spend on every rated profile.
Admin costs and “overhead” are looser everyday words. They usually mix support costs with part of fundraising. When you compare charities, prefer the filing categories above so you are comparing like with like.
What is a good spending ratio for a charity?
A good spending ratio is proportionate for the charity’s size and delivery model, not the smallest overhead you can find. In practice, many well-run UK charities report about 70–90% of expenditure on charitable activities (cause spend on CharityCompare). The rest typically funds fundraising and necessary running costs. Treat a ratio far outside that band — or a “100% to the cause” claim — as a prompt to read the accounts and trustees’ report, not as an automatic pass or fail. Always compare peers in the same cause and income band; a local rescue and a national research funder will never look alike.
What percentage is normal in the UK?
Across charities that publish full accounts, cause spend typically falls between 70% and 90%. That is a context band, not a target.
- Grant-makers can sit higher — their “delivery” is often writing cheques.
- Shop networks and public fundraisers often sit lower — raising the next pound costs money.
- Small volunteer-led groups can look extremely “efficient” because unpaid labour does not appear as expenditure.
So “charities with lowest admin costs UK” is a risky search intent if you treat the lowest number as the winner. The better search is charities where most money goes to the cause and the accounts still look competent.
Why “100% to the cause” is usually marketing
When an appeal promises every penny reaches the frontline, one of these is usually true:
- a founder or sponsor covers core costs separately,
- volunteers are carrying administration,
- or the claim quietly excludes categories of spending.
None of that automatically means better outcomes. A charity with no visible running costs may also have weak controls. For the longer treatment of scams and pressure appeals, see charity scams and fake appeals.
The overhead myth (and the starvation cycle)
Judging charities mainly on low overhead creates the starvation cycle: organisations under-invest in finance, safeguarding and systems to look lean, then become less effective and less safe.
That is why the Clarity Score caps Financial Efficiency at 20 of 100 points. Cause spend and fundraising ratios matter — they just must not outrank filing record, financial health and accountability.
How to compare charity admin costs properly
- Match model and scale — local service vs national campaigner vs research funder.
- Read cause spend and fundraising cost on each profile, not the homepage slogan.
- Check reserves in months — reserves explained.
- Check filing punctuality — late accounts are a competence signal.
- Put them side by side on the comparison tool.
- Read the trustees’ report where a ratio looks odd — silence is informative.
For famous brand match-ups, start with pages such as Cancer Research UK vs Macmillan or RSPCA vs Battersea.

Admin costs and CEO pay
Donors often jump from overhead questions to charity CEO pay UK. Pay bands are disclosed in the accounts; judge them against scale and complexity, not against a household salary. High senior pay at a huge service charity can be proportionate; the same figure at a tiny volunteer group deserves a harder look.

Every rated profile shows cause spend, fundraising spend, combined overhead, reserves in months and five-year trends from regulator filings.
