Total Headcount
Total number of employees (W-2 / direct-employment equivalents) across all departments at period end. The base denominator for nearly every other HR ratio — turnover rate, revenue per FTE, payroll as % of burn — so getting the snapshot date and the FTE-vs-headcount convention right matters. Common pitfall: mixing headcount (people) with FTE (capacity) — they diverge whenever part-time, contractor, or shared-services arrangements exist. Document the convention (typically "FTE-equivalent, employees only, end-of-period") at the board level once and apply consistently. — HR KPI, I'mBoard-authored (editorial tier).

Definition
Total number of employees (W-2 / direct-employment equivalents) across all departments at period end. The base denominator for nearly every other HR ratio — turnover rate, revenue per FTE, payroll as % of burn — so getting the snapshot date and the FTE-vs-headcount convention right matters. Common pitfall: mixing headcount (people) with FTE (capacity) — they diverge whenever part-time, contractor, or shared-services arrangements exist. Document the convention (typically "FTE-equivalent, employees only, end-of-period") at the board level once and apply consistently.
Formula
Count of active employees at period end. Convention: FTE-equivalent (a 0.5 FTE counts as 0.5), employees only (contractors tracked separately in `hr.total_contractors`). Snapshot is end-of-period unless the board has explicitly adopted an average-headcount convention for ratio math.Why it matters
The denominator for every HR ratio the board reads — turnover %, revenue/FTE, payroll as % of burn. Drift in this number without a corresponding hiring-plan update is a leading signal of unmanaged growth or quiet attrition.
How to interpret
Compare quarter-over-quarter against the approved headcount budget (hr.approved_headcount_budget). A delta above ±5% without a board note typically warrants explanation. Stage norm for SaaS (industry folk-wisdom, not citation-grade): seed 5–15, Series A 20–50, Series B 50–150, Series C 150–400.

Total Contractors
Count of active 1099 contractors, consultants, agencies-of-record, and similar non-employee labor at period end. Tracked separately from `hr.total_headcount` because the cost structure, retention dynamics, and classification risk are different. Common pitfall: under-counting agencies that bill on a project basis without per-head visibility — these often slip out of HR systems and surface only in finance AP detail. A contractor-to-FTE ratio above ~30% sustained typically warrants a classification audit and a deliberate "build vs rent" board conversation. — HR KPI, I'mBoard-authored (editorial tier).
Voluntary Exits
Count of employees who resigned during the period (initiated by employee, not the company). The numerator of the `hr.voluntary_turnover_rate` calculation and the headline "are we losing people" number boards anchor on. Common pitfall: ambiguous "mutually agreed" exits — companies sometimes log managed-out exits as voluntary to keep the visible number low. Define the test: if the employee initiated the conversation and there was no formal performance trigger, it is voluntary; otherwise log as termination. — HR KPI, I'mBoard-authored (editorial tier).
