How is annual leave calculated in the UK?
Under the Working Time Regulations 1998, most UK workers are entitled to 5.6 weeks' paid annual leave per year. For a full-time employee working 5 days/week, this equals 28 days (including bank holidays). Employers may offer more, but never less. The annual leave calculator above applies statutory minimum + NHS enhanced packages, and pro-rata for part-time staff.
Key UK rules for 2026:
- Part-time workers get pro-rata entitlement: days = 5.6 × (days worked per week)
- For irregular hours: use the 12.07% accrual method (hours worked × 0.1207 = annual leave hours)
- NHS Agenda for Change: full-time staff receive 27–33 days annual leave + 8 public holidays based on service length
- Bank holidays (England/Wales): 8 days; Scotland/NI may differ – our calculator uses 8 BH standard but can be adjusted manually.
Pro-rata annual leave examples (standard UK)
| Days worked per week | Statutory annual leave (days) | Including 8 bank holidays | Typical entitlement (days) |
|---|---|---|---|
| 5 (full-time) | 28.0 | 28 total | 20 days + 8 BH |
| 4 | 22.4 | 22.4 total | 16 days + 6.4 BH pro-rata |
| 3 | 16.8 | 16.8 total | 12 days + 4.8 BH pro-rata |
| 2.5 | 14.0 | 14.0 total | 10 days + 4 BH equivalent |
NHS part-time employees receive pro-rated annual leave based on full-time equivalent (FTE) using Agenda for Change bands.
📝 Quick checklist: How to calculate annual leave when starting mid-year / leaving job (2026)
- Accrued leave formula: (Entitlement ÷ 12) × completed months of service (rounded up after 15 days worked).
- For leavers, calculate accrued annual leave up to termination date – unpaid leave may be deducted.
- If your contract uses hours: total annual leave hours = (working hours per week × 5.6).
- NHS staff: use agenda for change annual leave calculator based on service anniversary; after 5 years you get +2 days, after 10 years +6 days (full-time).
- Pro rata for part time employees: divide full-time entitlement by 5 (days) then multiply by part-time days. Our tool does that instantly.
NHS annual leave calculator (Agenda for Change 2026)
Over 1.5 million NHS staff use Agenda for Change terms. Our nhs annual leave calculator applies the correct bands: 27 days + 8 BH (<5 years), 29 days + 8 BH (5-9 years), 33 days + 8 BH (10+ years). For part-time NHS employees, the tool pro-rates both annual leave and bank holidays based on contracted hours. This is particularly useful for nurses, paramedics, and administrative staff working shift patterns.
2026 update: NHS employers continue to allow flexible buying/selling of up to 5 days; our calculator reflects core entitlement only — contact ESR for precise balances.
⚖️ How to calculate pro rata annual leave for part-time & term-time workers
- Days-based: (Full-time entitlement ÷ 5) × days worked per week = part-time days.
- Hours-based: (Full-time weekly hours ÷ 5) × days worked per week × 5.6 = total annual leave hours.
- Term-time only: entitlement = (weeks worked ÷ 52) × full annual leave + bank holiday adjustment.
Pro tip: Always convert leave into hours if your schedule varies. The hourly method prevents underpayment for shift workers.
