FTE Calculation — Full Time Equivalent Calculator 2026

How this calculation works

A Full Time Equivalent (FTE) standardizes workforce measurement by expressing total hours as multiples of a standard full-time schedule (40 hours/week).

FTE matters for ACA compliance (50 FTE threshold triggers employer mandates), benefit eligibility, and headcount planning.

How this FTE Calculation — Full Time Equivalent Calculator works — 2026 guide

FTE calculation converts a mix of part-time and full-time hours into one comparable number by dividing total weekly hours by 40. One 40-hour employee is 1.0 FTE; two 20-hour employees also total 1.0 FTE. It is the backbone of ACA compliance (the 50-FTE employer mandate), benefit eligibility thresholds, and staffing benchmarks — and this 2026 FTE calculator does the math for a whole workforce in seconds.

How to use it in 3 steps

1. Enter each employee's weekly hours (or paste a list).
2. The calculator sums total hours and divides by 40 to produce the FTE total.
3. Read the FTE headcount and a flag if you cross the 50-FTE ACA threshold.

Who this is for

Small-business owners tracking the ACA 50-FTE line, HR teams building benefit-eligibility reports, and staffing planners.
