Payroll Run Rate

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. — HR KPI, I'mBoard-authored (editorial tier).

Definition

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.

Formula

Payroll Run Rate = Σ(employee fully-loaded annual comp). Fully-loaded ≈ base + bonus + employer taxes (Social Security, Medicare, FUTA, SUTA) + benefits (health, dental, 401k match) + equity refresh accrual. US-typical loading factor 1.20–1.30× base; international varies materially by country.

Why it matters

The single largest line in most operating budgets — drives runway calculus, dilution sensitivity at fundraise, and the unit economics conversation. Visible upward steps without a corresponding revenue or headcount-plan justification are board-action triggers.

How to interpret

Trend month-over-month; flag step-changes >5% that are not attributable to net new hires or planned comp cycles. Compare against hr.approved_headcount_budget × stage-typical avg comp (industry folk-wisdom, not citation-grade) to surface comp-band drift.
