Overtime Holiday Pay Calculator for UK Workers
This calculator determines how regular overtime affects your holiday pay entitlement under UK law. Following the landmark Bear Scotland v Fulton ruling (2014) and subsequent Employment Appeal Tribunal decisions, employers must include regular overtime in holiday pay calculations for at least the first 4 weeks of annual leave.
The ruling applies to all types of regular overtime: compulsory, guaranteed, non-guaranteed, and voluntary, provided it forms a "sufficiently regular and settled" pattern. The reference period for calculating average overtime is 52 weeks (from April 2020, increased from 12 weeks).
How Overtime Holiday Pay Is Calculated
Average weekly overtime is calculated using the last 52 working weeks (excluding any weeks with no pay). This means seasonal overtime patterns are smoothed across the year.
| Base Salary | Avg Weekly OT | Holiday Daily Rate | 4-Week Holiday Pay |
|---|---|---|---|
| £600/wk | £80 | £136 | £2,720 |
| £500/wk | £120 | £124 | £2,480 |
| £450/wk | £60 | £102 | £2,040 |
| £700/wk | £150 | £170 | £3,400 |
Which Leave Weeks Include Overtime?
UK holiday entitlement of 5.6 weeks is split legally into: 4 weeks under the Working Time Directive (Regulation 13) where overtime MUST be included, and 1.6 weeks additional UK statutory leave (Regulation 13A) where overtime is NOT legally required but some employers include it voluntarily.

Worked Example: Overtime Holiday Pay Calculator Uk
Here's a real-world example using the overtime holiday pay calculator uk. James earns £14.50 per hour as a warehouse supervisor and works 10 hours of overtime per week at time-and-a-half.
Overtime rate: £14.50 × 1.5 = £21.75 per hour
Weekly overtime pay: £21.75 × 10 = £217.50
Monthly overtime: £217.50 × 52 ÷ 12 = £942.50
Annual overtime: £217.50 × 52 = £11,310
Combined with his standard 40-hour week (£14.50 × 40 = £580/week), James's total annual earnings are £30,160 + £11,310 = £41,470 before tax.
UK Overtime Rules You Should Know

- Overtime and holiday pay: Since the Bear Scotland v Fulton ruling (2014), regular and systematic overtime must be included in holiday pay calculations. Use our overtime holiday pay calculator.
- Working Time Regulations: You cannot be forced to work more than 48 hours per week on average (over 17 weeks) unless you've opted out in writing.
- Tax on overtime: Overtime is taxed at your marginal rate — if it pushes you into the 40% bracket (above £50,270), you'll pay higher rate tax on the excess.
