▦ How this calculator works
Pro-rata salary is the full-time salary multiplied by the ratio of your hours to full-time hours. Pro-rata holiday scales the same way from the standard UK statutory minimum of 28 days (5.6 weeks) for a full-time employee.
◇ Assumptions and what's not included
Some employers offer more than the 28-day statutory minimum, holiday entitlement calculations can differ for irregular or term-time-only hours, and this doesn't include public holidays that may already be built into the 28-day figure.
▤ What to do next
Check your contract and your employer's holiday policy, since some roles calculate part-time holiday in weeks rather than days, or offer more than the statutory minimum.

Frequently asked questions
Is 28 days the legal minimum for everyone?+
28 days (5.6 weeks) is the UK statutory minimum for a full-time employee working a standard week — it's pro-rated down for part-time hours, as calculated here.
Does the 28 days include bank holidays?+
It can — many employers include bank holidays within the 28-day statutory minimum, though some offer them in addition, so check your contract.
Is pro-rata pay the same as the full-time hourly rate?+
Yes, pro-rata pay should give a part-time worker the same hourly rate as a comparable full-time employee, just for fewer hours.
What if my hours vary week to week?+
For irregular hours, holiday entitlement is often calculated as a percentage of hours worked (12.07%) rather than a fixed day count — this calculator assumes a fixed weekly hours pattern.
