About Full Time Equivalent Calculator

FTE converts a mixed workforce into a common unit by dividing total hours worked by standard full-time hours. Headcount and FTE diverge whenever part-time working is significant, and budgets should be built on FTE while people processes run on headcount.

Formulas

Total FTE

FTE = Total hours worked / Standard full-time hours

Part-time FTE

Part-time FTE = Total FTE - Full-time staff count

Assumptions and limits

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Should overtime count towards FTE?

No for establishment purposes — FTE measures contracted capacity. Track overtime separately as a signal of under-establishment.

Which should I report to the board?

FTE for cost and capacity, headcount for engagement, attrition and organisational reach. Reporting only one always misleads.
