Employee Turnover Cost

Estimates the total cost of losing and replacing an employee, summing direct costs (recruiting fees, signing bonuses, onboarding training) and indirect costs (lost productivity during vacancy, reduced productivity during ramp-up, knowledge transfer overhead).

Industry research from SHRM and Gallup places replacement cost at 50–200% of annual salary depending on role complexity. Specialist and senior roles cluster at the upper end; entry-level roles at the lower end.

The cost model decomposes turnover into five components. Separation costs (severance, exit processing, accrued PTO payout) are typically 5–10% of annual salary. Recruiting costs (job posting, agency fees, interview time) range from 5% (internal hire) to 30% (executive search firm). Onboarding and training (formal programs, manager time, materials) average 10–15%. Productivity ramp gap (the difference between full productivity and actual output during the new hire's learning period) is the largest and most variable component, ranging from 20% to 100% depending on role complexity. Knowledge transfer overhead and team disruption during the transition adds another 5–20%.

A worked example for a $120,000 senior software engineer. Separation: 7% = $8,400. Recruiting (in-house with technical screen overhead): 12% = $14,400. Onboarding (six-month ramp with manager investment): 15% = $18,000. Productivity gap (50% productivity for first three months, 75% for next three months, 90% thereafter, full at 12 months): roughly 45% of one year's salary in lost output = $54,000. Team disruption: 10% = $12,000. Total: $106,800, or about 89% of annual salary. The figure surprises managers who tend to think only of direct recruiting costs.

Knowledge-work roles cluster at the high end of the range because productivity ramp is long. A senior engineer joining a complex codebase takes 6–12 months to reach full productivity; tribal knowledge about why specific design decisions were made does not transfer cleanly through documentation. Manufacturing, retail, and hospitality roles ramp faster because tasks are more standardized; their turnover cost typically runs 30–60% of annual wages.

Beyond the direct cost, turnover has reputation and morale effects that the model surfaces but cannot quantify. High turnover signals problems to remaining employees, accelerating their own job search; the second and third departures cost more than the first because the team is already destabilized. Glassdoor reviews and employer-brand impact can extend recruiting costs into future hires for years.

Limitations: the calculator produces a single-role estimate. Aggregate turnover cost for a team requires summing per-role estimates, but interaction effects (team-level disruption, multiplicative manager time, project delays from knowledge gaps) are not additive. A 25% annual turnover rate on a 20-person team costs more than five times the single-role estimate due to compounding instability. For workforce planning, the simple multiplication understates the real impact.
