Part-Time Hours Percentage Calculator

Advice for this situation

This is useful when someone wants to translate actual weekly hours into an FTE-style percentage or compare part-time patterns consistently. In the UK, unpaid lunch breaks normally only come out of paid time when you are genuinely relieved from work, average weekly hours are usually checked over a longer reference period, and overtime premiums often come from the contract rather than one universal statutory rate.

Part-time percentages are often misunderstood when the underlying full-time benchmark was never agreed clearly. If your workplace uses paid breaks, on-call time, or shift differentials, compare the calculator result with your rota rule before treating the number as payroll-ready.

UK guidance on this page is a practical planning layer, not legal advice. If the answer affects pay, dismissal, leave entitlement, or a formal workplace process, verify it against the contract, policy, collective rule, or official guidance that applies to your role.

• Use the real full-time benchmark for your organisation rather than assuming one universal figure.
• An FTE percentage is useful for comparison, but weekly pattern and leave entitlement may still be handled differently.
• Keep the equivalent-days figure only as a summary, not as a replacement for the real hour pattern.
