UK holiday entitlement and holiday pay calculators

Three calculators for UK workers and employers: how much statutory holiday you get, how much has built up, and what a week of it should be paid at. Pick the one that matches your question — each shows its workings and the GOV.UK or Acas rule behind it.

United Kingdom. Working Time Regulations 1998 — 5.6 weeks of paid holiday, capped at 28 days on the statutory minimum. Rules checked 15 September 2026.

Which one do I need?

I work set days each week
Use the holiday entitlement calculator. Days a week × 5.6 gives the statutory year, capped at 28 days. It also handles a pro rata year if you joined or are leaving part-way through.
My hours change week to week
Use the irregular hours calculator. For leave years beginning on or after 1 April 2024, irregular-hours and part-year workers in Great Britain accrue 12.07% of the hours worked in each pay period. Northern Ireland has not adopted that method.
I know how much leave I have, but not what it pays
Use the holiday pay calculator. Entitlement and pay are separate calculations with separate rules.

England, Scotland, Wales and Northern Ireland

The 5.6-week minimum and the 28-day cap are the same across all four nations. The difference is accrual for irregular-hours and part-year workers: the 12.07% method comes from the 2023 amendment to the Working Time Regulations 1998, which applies in Great Britain. Northern Ireland has its own Working Time Regulations and has not adopted it, so the accrual tool is labelled Great Britain rather than UK.
