Holiday Entitlement Calculator
Almost all UK workers are entitled to at least 5.6 weeks of paid holiday a year — that is 28 days for someone working five days a week, usually including bank holidays.
Part-time workers and anyone starting part-way through the year get a pro-rated amount. Enter your working pattern to see your minimum legal entitlement.
How the calculation works
We believe numbers should be transparent. Here is the formula behind this calculator.

| Scenario | Your statutory minimum | Total entitlement | Pro-rated for this year |
|---|---|---|---|
| Full-time, full year | 28 days | 28 days | 28 days |
| Part-time (3 days), full year | 16.8 days | 16.8 days | 16.8 days |
| Full-time, started 6 months ago | 28 days | 28 days | 14 days |
| Full-time with 5 extra days | 28 days | 33 days | 33 days |
Important assumptions
- Uses the statutory minimum of 5.6 weeks (28 days for a full-time 5-day week).
- Shows the legal minimum only — your contract may give more, and the government proposes a 6.6-week minimum from October 2026.
- Pro-rating uses calendar months for part-year starts; employers may use weekly or daily methods.
- Bank holidays are normally included within the 28-day entitlement rather than extra on top.
Rates & official sources
Every calculation is based on the official rates and rules published by GOV.UK and HMRC.
Frequently asked questions
How much holiday am I entitled to by law?
Almost all workers are entitled to 5.6 weeks of paid holiday a year. For a full-time 5-day week that is 28 days, which usually includes the eight public holidays.
Does my part-time holiday get pro-rated?
Yes. Your entitlement is 5.6 × the days you work each week, so 3 days a week gives 16.8 days a year, and a shift worker’s entitlement is calculated in hours or shifts.
Are bank holidays included in my 28 days?
Usually yes. The statutory entitlement is 5.6 weeks in total, and most employers count public holidays within it. Your contract should say whether bank holidays are on top.
What if I start part-way through the year?
Your entitlement is pro-rated to the part of the holiday year you work. This calculator uses calendar months, but employers can legally use weekly or daily pro-rating instead.
