How To Calculate Holiday Pay

Calculate your statutory holiday pay entitlement based on your employment details

Comprehensive Guide: How to Calculate Holiday Pay in the UK (2024)

Understanding how to calculate holiday pay is essential for both employers and employees to ensure compliance with UK employment law and fair compensation. This guide explains the legal requirements, different calculation methods, and practical examples to help you determine accurate holiday pay entitlements.

1. Legal Framework for Holiday Pay in the UK

The right to paid holiday is established under the Working Time Regulations 1998, which implements the EU Working Time Directive. Key points include:

• Minimum entitlement: 5.6 weeks of paid holiday per year (28 days for full-time workers)
• Inclusion of bank holidays: Employers can choose to include the 8 UK bank holidays within the 28-day entitlement
• Accrual: Holiday entitlement builds up (accrues) as you work, typically at a rate of 1/12th of annual entitlement per month
• Payment: Holiday pay should be paid at your normal rate of pay, including regular overtime and commission in most cases

2. Who Qualifies for Holiday Pay?

Almost all workers are entitled to holiday pay, including:

• Full-time and part-time employees
• Agency workers
• Workers on zero-hours contracts
• Casual workers
• Apprentices

The only exceptions are:

• Genuinely self-employed individuals
• Members of the armed forces
• Police officers (who have separate arrangements)

3. Different Methods for Calculating Holiday Pay

The calculation method depends on your work pattern and pay structure:

Work Pattern	Calculation Method	Example
Fixed hours and pay	Week’s pay = normal weekly wage Daily pay = weekly wage ÷ 5	£500 weekly wage = £100 per day
Shift workers	Average pay over previous 52 weeks (excluding weeks with no pay)	£480 average weekly pay = £96 per day
Variable hours	Average hours over 52 weeks × hourly rate	25 avg hours × £12 = £300 per week
Casual/irregular hours	12.07% of hours worked (based on 5.6 weeks’ holiday)	100 hours worked = 12.07 holiday hours

4. Step-by-Step Calculation Process

1. Determine entitlement: Full-time workers get 5.6 weeks (28 days). Part-time workers get a pro-rata amount based on their hours.
2. Calculate daily pay:
   • For fixed hours: Divide weekly pay by 5
   • For variable hours: Use the 52-week average method
3. Account for part-years: If you haven’t worked the full year, calculate pro-rata entitlement based on months worked.
4. Include regular payments: Holiday pay should include:
   • Regular overtime (if it’s part of your normal working pattern)
   • Commission payments
   • Performance-related bonuses
   • Shift allowances
5. Exclude one-off payments: Bonuses that aren’t regular (like Christmas bonuses) typically aren’t included.

5. Special Cases and Common Questions

What about bank holidays?

Employers can choose whether to include bank holidays within the 28-day entitlement or offer them as additional days. There’s no legal requirement to give bank holidays as paid leave, but most employers do.

How does holiday pay work for zero-hours contracts?

Workers on zero-hours contracts accrue holiday pay at a rate of 12.07% of hours worked. This is because 5.6 weeks’ holiday represents 12.07% of hours worked in a year (5.6/46.4).

What happens to unused holiday when leaving a job?

You’re entitled to be paid for any untaken holiday when you leave a job. This is calculated based on your accrued entitlement up to your leaving date.

Can my employer pay me instead of giving holiday?

No, except when your employment ends. It’s illegal for employers to offer “rolled-up” holiday pay (including holiday pay in your regular wage) for current workers.

6. Recent Legal Developments (2023-2024)

Several important cases have clarified holiday pay calculations:

• Harpur Trust v Brazel (2022): Confirmed that part-year workers (like term-time only workers) are entitled to 5.6 weeks’ holiday, not pro-rata based on hours worked.
• Agnew v Chief Constable (2023): Clarified that voluntary overtime should be included in holiday pay if it’s sufficiently regular and settled.
• New calculation rules (April 2024): The government introduced new regulations for calculating holiday pay for irregular hours and part-year workers, using a 52-week reference period.

7. Practical Examples

Example 1: Full-time worker with fixed hours

Sarah works 35 hours per week, 5 days a week at £15 per hour.

• Weekly pay: 35 × £15 = £525
• Daily pay: £525 ÷ 5 = £105
• Holiday entitlement: 28 days
• Total holiday pay: 28 × £105 = £2,940 per year

Example 2: Part-time worker with variable hours

James works 20 hours per week on average, at £12 per hour.

• Average weekly pay: 20 × £12 = £240
• Pro-rata entitlement: (20/35) × 28 = 16 days
• Daily pay: £240 ÷ 5 = £48
• Total holiday pay: 16 × £48 = £768 per year

Example 3: Zero-hours contract worker

Emma has worked 120 hours over 3 months at £11 per hour.

• Holiday accrued: 120 × 12.07% = 14.48 hours
• Holiday pay value: 14.48 × £11 = £159.28

8. Common Mistakes to Avoid

Mistake	Why It’s Wrong	Correct Approach
Using basic pay only	Excludes regular overtime/commission that should be included	Use average pay over 52 weeks including regular payments
Pro-rata for part-year workers	Against Harpur Trust ruling for term-time workers	Give full 5.6 weeks entitlement
Not paying for untaken holiday on termination	Illegal under Working Time Regulations	Pay for all accrued but untaken holiday
Using 12.07% for all workers	Only applies to irregular hours workers	Use standard calculation for regular workers
Not updating for pay rises	Holiday pay should reflect current pay rate	Recalculate when pay changes

• Keep accurate records of hours worked and holidays taken
• Review calculations annually and when pay rates change

• Be transparent about how holiday pay is calculated

11. Employee Rights and Disputes

If you believe your holiday pay has been calculated incorrectly:

1. First raise the issue informally with your manager or HR
2. If unresolved, make a formal grievance
3. You can make a claim to an employment tribunal if the issue isn’t resolved

12. Future Developments

The UK government is currently consulting on potential reforms to holiday pay calculations, particularly regarding:

• Simplifying calculations for irregular hours workers
• Potential changes to the reference period for calculating average pay
• Clarifying the treatment of overtime and commission
• Possible introduction of a single rate for all workers

Employers and workers should stay informed about these potential changes, which may come into effect in 2025.

Conclusion

Calculating holiday pay correctly is crucial for both legal compliance and fair treatment of workers. While the basic principle of 5.6 weeks’ paid holiday is straightforward, the actual calculations can become complex depending on work patterns, pay structures, and individual circumstances.

For most workers, the key points to remember are:

• You’re entitled to at least 5.6 weeks’ paid holiday per year
• Holiday pay should be calculated based on your normal pay, including regular overtime and commission
• Part-time workers get a pro-rata entitlement based on their hours
• You continue to accrue holiday during sick leave and maternity leave
• You should be paid for any untaken holiday when you leave a job

If you’re unsure about your holiday pay entitlement or calculations, don’t hesitate to seek advice from official sources like ACAS or Citizens Advice. For employers, investing in proper payroll systems and training can help avoid costly mistakes and potential tribunal claims.
