Holiday Entitlement Calculator

The Holiday Entitlement calculator works out your statutory annual leave in days and hours, for full-time, part-time, irregular hours and shift workers, under the Working Time Regulations 1998. UK statutory minimum is 5.6 weeks per year — equivalent to 28 days for a 5-day-week worker, including bank holidays if the employer chooses to roll them into the 5.6 weeks. Part-time workers receive 5.6 × their normal weekly working days. A 3-day-a-week worker gets 16.8 days, typically rounded up to 17. In 2025/26 the 5.6 weeks is split into 4 weeks derived from EU law and 1.6 weeks of UK top-up. The EU 4 weeks must be taken in the leave year and include normal pay elements like regular overtime, commission and shift premiums (Bear Scotland and subsequent rulings, averaged over a 52-week reference period). The 1.6 UK weeks can be carried forward by agreement and is paid at basic salary only. For irregular hours and part-year workers, the rules changed in April 2024: holiday accrues at 12.07% of hours worked in each pay period, and rolled-up holiday pay (added to each hour's pay) is legal again with a clearly itemised payslip element. This affects zero-hours, casual and term-time-only workers. This tool is for employees verifying their entitlement, HR teams calculating accrual on leaver dates, and managers planning team cover. It is also useful for new joiners (pro-rata in the first leave year), maternity returners (accrual continues during paid and unpaid maternity leave), and long-term sick employees (accrual continues; untaken leave can carry forward up to 15 months). What the calculator does NOT include: contractual leave above the statutory 5.6 weeks (many employers offer 25-30 days plus bank holidays), buy-and-sell schemes, sabbatical interactions, public-sector leave loading, the specific 52-week reference period for variable-pay holiday pay, or the rolled-up payslip rules in fine detail. It assumes a single PAYE employment with a clear leave year. Regional notes: WTR 1998 applies UK-wide, but bank holidays differ — England and Wales have 8, Scotland has 9 (St Andrew's Day), Northern Ireland has 10 (St Patrick's, Battle of the Boyne). Check whether your contract treats local holidays as paid leave. Pair with the Salary Converter, Take-Home Pay and Sick Pay calculators.
