Analytics calculator
FTE Calculator
Estimate actual full-time-equivalent staffing by comparing total hours worked to a standard full-time schedule across the measured period. This helps HR, finance, and workforce planners translate hours into comparable capacity.

FTE Formula
FTE = Total Hours Worked / (Standard Weekly Hours × Weeks in Period)
Inputs used in this calculator
- Total Hours Worked: Labor hours included under your organization’s documented planning rule for the measured period.
- Standard Weekly Hours: The full-time weekly schedule used by your organization.
- Weeks in Period: Number of weeks included in the reporting period.
How to use the result
- Enter the total hours worked in the measured period.
- Enter the standard weekly full-time hours used by your organization.
- Enter the number of weeks included in the period.
- Review actual FTE and compare it to the staffing plan.
Method, scope, and sources
Compact and advanced Total-hours mode calculate actual hours-based planning FTE = total included hours ÷ (selected standard weekly hours × weeks in period). Advanced Workforce-groups mode calculates modeled schedule-capacity FTE = Σ(entered group count × typical weekly hours) ÷ standard weekly hours. The two modes use different source data and are not automatically reconciled.
State the full-time baseline and inclusion rules for regular, overtime, paid leave, agency, and contractor hours. Workforce-group counts are entered allocations, not inferred or deduplicated headcount, and their result is modeled schedule capacity rather than delivered hours. The tool does not determine employment, benefits, overtime, tax-credit, or statutory-reporting FTE. A 52-week output is only a projection.
Method status: Partially supported.
Worked example
Hypothetical Workforce-groups mode: 10 entered people at 40 typical weekly hours and four at 20 hours provide 480 modeled weekly hours. With a 40-hour baseline, modeled schedule-capacity FTE = 480 ÷ 40 = 12.00. The entered group-count sum is 14, but it is not an inferred unique headcount.

- U.S. Government Accountability Office — Full-time equivalent (FTE) employment: Defines a federal-survey FTE as regular straight-time hours divided by compensable fiscal-year hours and gives 2,080 hours as one FTE; it also explicitly excludes overtime and holiday hours.
- Internal Revenue Service — Small Business Health Care Tax Credit Questions and Answers: Determining FTEs and Average Annual Wages: Documents tax-credit-specific employee, paid-hours, cap, and rounding rules, supporting the warning that compliance FTE differs from this planning calculator.
Questions about this calculation
Why does FTE matter in HR planning?
FTE creates a common capacity unit that helps teams compare part-time, full-time, overtime, and contingent staffing on one planning scale.
Can FTE be higher than headcount?
FTE can exceed planned headcount equivalents when overtime, agency coverage, or extended schedules create more labor capacity than the baseline staffing plan.
