Annual Leave Entitlement Calculator
Work out statutory holiday entitlement for part-time or full-time work.
What is the Annual Leave Entitlement Calculator?
An annual leave entitlement calculator works out your pro-rated statutory holiday allowance if you work part-time, based on your working pattern relative to a full-time equivalent. It works by taking the full-time statutory minimum entitlement (which includes bank holidays within it under UK law) and scaling it down proportionally to how many days a week you actually work. To calculate it manually: (your days worked per week ÷ 5) × the full-time entitlement — for example, working 3 days a week against a 28-day full-time entitlement gives (3 ÷ 5) × 28 = 16.8 days. Always check gov.uk for the current statutory minimum and how your specific employment contract treats bank holidays, since some employers offer more than the legal minimum.
How it works
Part-time holiday entitlement is calculated pro-rata against the full-time equivalent — if you work a fraction of a standard five-day week, you're entitled to that same fraction of the full-time statutory minimum, keeping the entitlement proportionate regardless of your specific working pattern.
UK context
The UK statutory minimum holiday entitlement applies to almost all workers, not just employees on traditional five-day patterns, and irregular hours or compressed working patterns still need to be calculated fairly on a pro-rata basis rather than simply being excluded. Many employers offer more than the statutory minimum as a contractual benefit, so your actual contractual entitlement may be higher than the statutory calculation shown here.
Tips
- Check your contract for your actual entitlement — many employers offer more than the statutory minimum, and this calculator only shows the pro-rated statutory baseline.
- If your working pattern varies week to week (rather than a fixed number of days), calculating fair pro-rata entitlement is more complex — check gov.uk's guidance for irregular hours workers specifically.
- The UK statutory minimum is generally understood to include bank holidays within it (rather than on top of it) unless your contract says otherwise — worth checking which applies to you.
Frequently asked questions
How is part-time holiday entitlement calculated?
By pro-rata against the full-time equivalent — your days worked per week divided by five (a standard full-time week), multiplied by the full-time statutory minimum entitlement.
Does statutory annual leave include bank holidays?
Generally yes, by default — the UK statutory minimum is usually understood to include bank holidays within the total rather than on top of it, though many employers offer bank holidays as an addition to the statutory minimum as a contractual benefit. Check your specific contract.
A quick note
Uses simple pro-rata calculation. The UK statutory minimum is set by law — check gov.uk for the current figure and how your specific contract treats bank holidays.
