Thinking of moving into charity work part-time — or already there and trying to decode your payslip? A typical charity part time salary uk job advert quotes a full-time salary and adds “pro rata”, leaving you to work out what you’d actually earn on three or four days a week. The charity sector has its own quirks: pay is often lower than the private sector for equivalent roles, London weighting varies wildly, and many roles are funded by fixed-term grants that shape the hours on offer.
This guide covers how part-time charity salaries work across the UK: typical full-time benchmarks by role, the pro-rata calculation with worked examples, how fundraising-linked and grant-funded posts handle part-time hours, and what to know about pensions, holiday, and the sector’s well-known pay gap. Want the number without the maths? Our free pro rata salary calculator will work it out from your hours in seconds.
How charity pay compares
Let’s be honest up front: charity salaries generally sit 10–20% below equivalent private-sector roles, and sometimes further below in fundraising-adjacent or junior posts. The sector compensates partly with mission, flexibility, and often generous holiday allowances (28–32 days plus bank holidays is common). For part-time workers, the flexibility is frequently the main draw — term-time hours, compressed weeks, and genuine flexible working are more widespread here than in most industries.
Typical full-time (FTE) salary benchmarks across common charity roles look roughly like this. Treat these as illustrative ranges — they move with each pay round and vary enormously between a large national charity and a small local one:
| Role | Typical FTE salary range |
|---|---|
| Fundraising assistant / officer (junior) | £24,000–£28,000 |
| Fundraising manager | £32,000–£42,000 |
| Communications officer | £26,000–£32,000 |
| Communications manager | £34,000–£44,000 |
| Volunteer coordinator | £25,000–£30,000 |
| Project / programme officer | £27,000–£34,000 |
| Project / programme manager | £35,000–£48,000 |
| Finance assistant | £25,000–£30,000 |
| Finance manager | £38,000–£50,000 |
| Administrator / support officer | £23,000–£27,000 |
| Head of department | £45,000–£65,000 |
| CEO (small charity) | £45,000–£60,000 |
| CEO (large national charity) | £80,000–£150,000+ |
London-based roles typically carry £3,000–£5,000 more than the same role elsewhere, though the capital’s premium has been eroding as remote and hybrid working spread through the sector.
The pro-rata calculation, step by step
Charity full-time hours are usually 35 hours per week (7 hours × 5 days) — shorter than the 37.5 common in the NHS or local government. Some charities use 37 or 37.5; a few still use 36. The formula is the same everywhere:
Your salary = FTE salary × (Your hours ÷ Full-time hours)
Worked example 1: part-time fundraising officer
A fundraising officer role is advertised at £30,000 FTE on a 35-hour week. You take it at 4 days a week (28 hours):
- Fraction of full-time: 28 ÷ 35 = 0.8 FTE
- Pro-rata salary: £30,000 × 0.8 = £24,000 per year
- Monthly gross: £24,000 ÷ 12 = £2,000
- Weekly gross: £24,000 ÷ 52 = £461.54
Worked example 2: three-day-a-week comms officer
A communications officer post at £28,000 FTE, 35-hour week, taken at 21 hours (3 days):
- Fraction: 21 ÷ 35 = 0.6 FTE
- Pro-rata salary: £28,000 × 0.6 = £16,800 per year
- Monthly gross: £1,400
- Effective hourly rate: £28,000 ÷ (35 × 52) = £15.38/hour — useful for comparing with freelance day rates
Worked example 3: school-hours project officer
A programme officer role at £32,000 FTE on a 37-hour week (some charities use 37), taken term-time-friendly at 25 hours:
- Fraction: 25 ÷ 37 ≈ 0.676 FTE
- Pro-rata salary: £32,000 × 0.676 ≈ £21,622 per year
Notice how the full-time hours figure changes everything — the same 25 hours is worth more on a 37-hour contract than a 35-hour one. Always check the contract’s full-time hours before accepting.
Part-time charity pay at a glance
Based on a £30,000 FTE salary on a 35-hour week:
| Pattern | Hours | FTE | Annual salary | Monthly gross |
|---|---|---|---|---|
| 2 days | 14 | 0.4 | £12,000 | £1,000 |
| 3 days | 21 | 0.6 | £18,000 | £1,500 |
| 4 days | 28 | 0.8 | £24,000 | £2,000 |
| 4.5 days | 31.5 | 0.9 | £27,000 | £2,250 |
| 5 days | 35 | 1.0 | £30,000 | £2,500 |
Grant-funded and fixed-term posts
A large share of charity roles — especially project officers, outreach workers, and community posts — are funded by grants with fixed end dates. This affects part-time pay in a few ways:
- Hours tied to the grant budget. A funder may only cover 0.6 FTE of a project officer; the hours aren’t negotiable because the money literally isn’t there.
- Fixed-term contracts. Common lengths are 12 months, 2 years, or 3 years. Your pro-rata salary is the same maths, but check what happens at the end — some contracts end, others get extended or made permanent.
- Notice and redundancy. Fixed-term staff with 2+ years’ service have redundancy rights, and pro-rata redundancy pay applies. Many charity workers don’t realise this.
- Salary uplifts. Grant budgets are often fixed in cash terms, so annual pay rises may be smaller (or zero) on grant-funded posts compared with core-funded ones.
If you’re comparing a charity offer with a private-sector one, factor in the whole package: charities often offer 28–30 days’ holiday plus bank holidays, good flexible working, and sometimes enhanced sick pay or sabbaticals — all worth real money.
The charity pay gap and what it means for negotiation
The sector’s pay gap with the private sector is well documented, but within charities there’s another pattern worth knowing: smaller charities pay less than larger ones for the same job title, and London weighting is inconsistent — some charities pay a formal £3k–£5k London allowance, others simply set a higher London salary band, and some pay no differential at all.
When negotiating a part-time charity salary:
- Negotiate the FTE figure, not the pro-rata figure. It’s cleaner and avoids rounding confusion.
- Ask about the pay scale. Many larger charities have published salary bands — find out where the role sits and what progression looks like.
- Check the London weighting policy if the role is hybrid — some charities pay it based on your contractual work location.
- Factor in the benefits. An extra 5 days’ holiday over statutory is worth roughly 2% of salary; a good pension match can be worth 5–8%.
Holiday entitlement for part-time charity staff
Statutory minimum is 5.6 weeks, scaled to your days. But many charities are more generous — 25 days plus bank holidays full-time is typical, and 28–30 isn’t unusual at larger organisations. A 3-day-a-week worker at a charity offering 28 days plus 8 bank holidays (36 total) would get 36 × 0.6 = 21.6 days of paid leave. That’s nearly a week more than the statutory minimum for the same hours — one of the sector’s genuine perks.
Pensions in the charity sector
Most charities use defined-contribution workplace schemes (NEST, People’s Pension, Aviva, or similar) with auto-enrolment. Employer contributions are often above the statutory minimum — 6–10% employer contributions are common at medium and large charities, versus the 3% legal minimum. On a £24,000 part-time salary, the difference between 3% and 8% employer contribution is £1,200 a year of free money. Always check the employer’s rate, not just your own.
Comparing two part-time charity offers
When you’re choosing between offers, don’t compare the pro-rata figures directly — compare the FTE salaries and the benefits side by side. A £30,000 FTE role at 3 days a week (£18,000) with 30 days’ holiday and an 8% pension beats a £32,000 FTE role at 3 days (£19,200) with statutory minimums, once you value the extra leave and pension contributions. The headline £1,200 gap shrinks fast when the better package is worth £2,000+ a year in kind.

FAQs
What is a typical charity part time salary in the UK?
It depends on the role, but a mid-level charity post (fundraising officer, comms officer, project officer) typically pays £27,000–£34,000 full-time. At 3 days a week (0.6 FTE on a 35-hour week), that’s roughly £16,200–£20,400 a year. Junior admin and support roles sit lower, around £23,000–£27,000 FTE.
How do I calculate pro-rata pay for a charity job?
Multiply the full-time salary by your weekly hours divided by the charity’s full-time hours (usually 35). Example: £30,000 × (21 ÷ 35) = £18,000 per year for a 3-day week. Our free pro rata salary calculator handles the sums.
Do charities pay less than the private sector?
Generally yes — typically 10–20% less for equivalent roles, though the gap narrows at senior levels and in specialist functions like finance and digital. The trade-off is usually better flexibility, more generous holiday, and mission-driven work.
Are part-time charity workers entitled to the same benefits?
Yes. Part-time workers have the legal right to the same pro-rata pay, holiday, and benefits as full-time colleagues. That includes pension auto-enrolment, sick pay, and parental leave — scaled to your hours where the benefit is time-based.
