Employee Turnover Cost Calculator

Losing an employee costs between 50% and 200% of their annual salary. That range exists because most organisations only count the recruiting fee — and miss everything else.

The five cost components

1. Separation costs (~4% of salary) Exit interviews, HR processing, final payroll, unemployment insurance increase.

2. Vacancy costs (daily rate × days to fill) Work either doesn't get done (lost output) or gets redistributed to teammates (hidden productivity tax). Average time to fill: 42 days across all roles; 84 days for senior/specialised roles.

3. Recruiting costs (~15% of salary) Agency fees run 15–25% for professional roles. In-house recruiting time averages 80–100 hours per hire when you include sourcing, screening, interviews, and offers.

4. Onboarding costs (~12% of salary) Formal training, documentation, manager time, IT setup, compliance training.

5. Ramp-to-productivity (~25% of salary) A new hire typically reaches 80% productivity at 3–6 months. The gap between 100% and 80% productivity over that period is a real cost on your P&L.

Total: ~56–60% of annual salary for a mid-level role For senior roles (director and above), multiply by 1.5–2×.

Use the employee turnover cost calculator to model what each departure actually costs your business.

Base salary is only one component of what an employee costs. For budgeting and hiring decisions, you need the fully-loaded cost.

Employer cost components

Mandatory costs (required by law): - Social Security: 6.2% on first $168,600 wages - Medicare: 1.45% (uncapped) - FUTA: 0.6% on first $7,000 - State unemployment (SUTA): 0.5–10% depending on state and experience - Workers' compensation: 0.1–10% depending on industry and state

Voluntary benefits (typical US employer): - Health insurance: $5,000–$15,000/year/employee (employer contribution) - Dental/vision: $500–$1,500/year - 401(k) match: 3–5% of salary - Life insurance: $300–$600/year - HSA contribution: $0–$2,000/year

Equipment and overhead: - Laptop and peripherals: $1,500–$3,500 (annualised) - Software licenses (Slack, Zoom, tools): $1,000–$3,000/year - Desk and office space: $3,000–$8,000/year in office; ~$0 remote

Rule of thumb for budgeting

Total employer cost = base salary × 1.25–1.45

For a $100k salary: budget $125k–$145k including all-in costs.

Turnover adds on top

If that employee leaves, add 50–75% of annual salary for replacement cost. A $100k employee who leaves costs another $50k–$75k to replace.

Total turnover cost is useful for a top-line number, but voluntary and involuntary departures have meaningfully different cost profiles — and more importantly, they point to completely different root causes.

Why the cost profile differs

Voluntary turnover (resignations) is almost always more expensive per departure. It's harder to predict, so there's less time to plan a transition, knowledge transfer is often rushed or incomplete, and the departing employee's morale-related impact on the remaining team tends to be larger — voluntary departures, especially of strong performers, can trigger additional voluntary departures ("turnover contagion").

Involuntary turnover (terminations, layoffs) is more predictable and plannable — the organization usually controls the timing, can prepare a transition plan and knowledge handoff in advance, and there may be lower morale impact on the team if the departure was clearly performance-related or role-elimination-related.

What each type signals

A high voluntary rate points inward — something about the day-to-day experience is pushing people out. A high involuntary rate points to the hiring funnel — the wrong people are getting hired for the role in the first place, or expectations weren't set clearly at the outset.

Regrettable vs non-regrettable voluntary turnover

Not all voluntary turnover is equally costly. Losing a strong performer ("regrettable") carries the full replacement cost plus lost institutional knowledge and momentum. Losing a low performer who was likely to be managed out anyway ("non-regrettable") is much closer in cost profile to a planned involuntary departure. Track this split if you want an accurate read on how much turnover is actually hurting the business.

Frequently asked questions

Should layoffs be counted the same as individual terminations? Track them separately — layoffs are driven by business strategy (cost reduction, restructuring) rather than individual performance or hiring quality, and shouldn't be blended into a "hiring mismatch" root-cause analysis.

Does severance change the cost comparison? Yes — involuntary departures often carry severance costs voluntary ones don't, which can partially offset the higher indirect costs (contagion, rushed handoff) typical of voluntary departures.
