FTE Metrics

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.

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.

Annualized fully-loaded payroll cost based on current employee compensation — wages plus employer-paid taxes, benefits, and typical equity refresh allocation. Used as the dominant input into `hr.payroll_as_pct_of_burn` and the projection for `hr.fte_metrics`. Common pitfall: reporting base-salary-only and missing employer payroll taxes, benefits, and bonus accrual — this can understate true cost by 15–30%. Document the loading convention (typically wages × 1.20–1.30 for US fully-loaded) and apply consistently.

Annual Recurring Revenue divided by total FTE-equivalent workforce — the canonical SaaS workforce-productivity ratio anchored to the SaaS Capital Annual Survey methodology (revenue per employee benchmarks). A high-signal denominator for "are we over- or under-staffed for our revenue scale?" Common pitfall: choosing different ARR conventions (ending vs average, GAAP-reconciled vs raw) without locking in a board-level standard. Best practice is to pair this with `sales.arr` so the numerator is unambiguous and to disclose whether contractors are included in the FTE denominator.

Monthly fully-loaded payroll cost as a percentage of `finance.gross_burn_rate`. Tells the board what share of cash outflow funds people vs everything else (infra, GTM spend, professional services, facilities). Common pitfall: comparing this ratio across companies without normalizing for stage and capex intensity — a pure-software seed company will run very payroll-heavy; a hardware-or-bio company will not. Best practice is to read this in conjunction with the burn-rate trend, not in isolation.
