Part Time FTE Calculator

Convert part-time hours into full-time equivalents for headcount and budget reporting.

About Part Time FTE Calculator

FTE normalises a mixed workforce so budgets and productivity can be compared. The gap between headcount and FTE matters operationally, because management overhead scales with people rather than with hours. Reporting headcount where FTE is meant overstates capacity, and reporting FTE where headcount is meant understates the management load.

Formula

Part Time FTE

FTE = part-time hours ÷ full-time hours; pro-rata salary = full-time salary × FTE

FTE
A full-time employee counts as 1.0 regardless of the hours their contract specifies
