FTE Calculator (Full-Time Equivalent, Pro-Rata Pay and Headcount)
Full-time equivalent of a part-time schedule, the pro-rata pay, the FTE of a group, and how many people or FTEs are needed to cover a weekly workload.

What this tool does
FTE turns different working patterns into one yardstick: one person on a full-time week counts as 1, someone working 24 hours of a 40-hour week as 0.6, and two people on 20 hours as 1 together. It is the figure behind staffing plans, budgets and headcount reports. What counts as a full-time week varies by employer, sector and country — 35, 37.5, 40 hours — so enter yours rather than assuming 40. Pro-rata pay is the simple proportion; real contracts may add rules about benefits, minimums and overtime, so treat it as a first estimate.
Formula
FTE = weekly hours ÷ full-time weekly hours · pro-rata pay = full-time pay × FTE

Limitations
- The tool works with whatever currency you use for the inputs; it does not convert between currencies.
- The result is an estimate based only on the values you type. Real situations often include factors this calculator does not know about.
