Days Off Calculator (Paid Time Off Entitlement)

Quick answer

The days off calculator estimates your paid time off entitlement for a year – from your country's statutory minimum or your contract – prorated for part-time hours and for starting or leaving part-way through the year.

Full-time entitlement
— days
Your days off this year
— days
In hours (8-hour days)
— hours

There is no legal minimum paid vacation in the U.S., though most employers offer 10–15 days. The UK guarantees 5.6 weeks (28 days for a five-day week, which can include public holidays), and EU law guarantees at least 4 weeks.

How it works

Choose your country or enter your contract days, your working days per week and the months you work in the leave year.

Tips

  • Use figures for the same period (a month, a quarter or a year) for every input so ratios compare like with like.
  • Track the metric over time – the trend usually tells you more than a single value.
  • Compare your result with industry benchmarks, which vary a lot between sectors.
  • Treat the result as a starting point for a decision, then check the assumptions behind each input.

Common mistakes to avoid

  • Mixing monthly and yearly numbers in the same calculation.
  • Using revenue where the formula needs profit (or the other way round).
  • Forgetting hidden costs such as taxes, fees, overheads or your own time.
