Pro Rata Salary for 1 Day a Week

Find out what a full-time salary converts to when you work 1 day a week. Working 1 day out of a standard 5-day week means you are 20% FTE.

You also receive a pro-rata share of statutory holiday: 5.6 days out of the full-time 28-day entitlement, as set out by GOV.UK and guaranteed under the Part-time Workers Regulations 2000.
