Involuntary Turnover Rate
Annualized rate of company-initiated separations as a percentage of average headcount. Complement to `hr.voluntary_turnover_rate`; together they form the total turnover picture per the Mercer US Turnover Survey methodology. Common pitfall: lumping one-time RIFs into the steady-state rate, which makes the trend unreadable. Best practice is to report steady-state involuntary turnover and call out any RIF events separately in `hr.board_actions` with the headcount delta. — HR KPI anchored to Mercer US Turnover Survey 2025.

Definition
Annualized rate of company-initiated separations as a percentage of average headcount. Complement to hr.voluntary_turnover_rate; together they form the total turnover picture per the Mercer US Turnover Survey methodology. Common pitfall: lumping one-time RIFs into the steady-state rate, which makes the trend unreadable. Best practice is to report steady-state involuntary turnover and call out any RIF events separately in hr.board_actions with the headcount delta.
Formula
Involuntary Turnover Rate (annualized) = (Terminations in period / Average Headcount in period) × (12 / months in period) × 100. Convention: exclude announced RIF events from the steady-state series; report them separately with headcount delta. Per Mercer US Turnover Survey methodology.Why it matters
A read on performance-management cadence and any active restructuring. Sustained near-zero raises questions about management discipline; sustained-elevated raises questions about hiring quality or strategy thrash.
How to interpret
US all-industry total turnover historically clusters in the 18–25% annualized range per Mercer US Turnover Survey 2025 (§Total Turnover); involuntary typically represents 4–8% of that total (verify exact splits against the cited report — distributions vary by industry). Companies with very low involuntary rates (<2% annualized) often have buried under-performers; companies above ~8% steady-state typically have a hiring or onboarding-quality issue (industry folk-wisdom on the upper bound, not citation-grade).

Average Days to Fill
Mean elapsed days between requisition opening (approved and posted) and offer acceptance, averaged across requisitions filled in the period. The headline recruiting-velocity KPI commonly tracked in the SHRM Talent Acquisition Benchmarking Report. Common pitfall: choosing between time-to-fill (req-opened to offer-accepted) and time-to-hire (first-applicant to offer-accepted) without locking the convention — the two can differ by weeks. Best practice is to standardize on time-to-fill (the SHRM benchmark convention) and document any deviation. — HR KPI anchored to SHRM Talent Acquisition Benchmarking Report.
Voluntary Turnover Rate
Voluntary exits over a trailing period, expressed as an annualized percentage of average headcount — the headline attrition number on the HR scorecard. Anchored to the Mercer US Turnover Survey methodology (Mercer reports voluntary vs involuntary turnover annually). Common pitfall: comparing a single quarter's annualized rate against an annual benchmark — short-window annualization is noisy. Best practice is trailing-12-months for benchmark comparison and trailing-3 or trailing-6 for trend reads. Per #1426: stage-specific industry norms here are folk-wisdom unless tied to a specific Mercer or comparable published cut. — HR KPI anchored to Mercer US Turnover Survey 2025.
