What is Employee Turnover Cost?
Employee turnover cost is the total financial impact of an employee leaving, encompassing recruitment, onboarding, training, lost productivity during the vacancy, and reduced output during the new hire's ramp-up period. The true cost is typically 50-200% of the departing employee's annual salary. Plan recruitment with the Recruitment Cost Calculator and track hiring efficiency with the Hiring Speed Calculator.
The Formula
Cost per Departure = Recruitment Cost + Onboarding/Training + Lost Productivity During Vacancy + Lost Productivity During Ramp-Up
The total cost of replacing an employee is typically 50-200% of their annual salary, depending on seniority.
Worked Example
A mid-level employee earning $45,000 leaves. Recruitment costs $8,000, onboarding $3,000, 60-day vacancy, and 90-day ramp-up for the replacement.
- Recruitment = $8,000
- Onboarding/training = $3,000
- Vacancy cost (60 days × $175/day revenue impact) = $10,500
- Ramp-up cost (90 days at 50% productivity × $175/day) = $7,875
- Total = $8,000 + $3,000 + $10,500 + $7,875 = $29,375
📌 Total turnover cost: $29,375, 65% of the employee's annual salary. With 15% annual turnover in a 50-person company, that's 7-8 departures costing $205,000-235,000/year.
Why This Matters
Retention ROI
A $2,000/year retention investment (training, development, wellness) that prevents one departure saves $29,000. Retention programs costing $100,000 for 50 employees only need to prevent 3-4 departures to break even.
Knowledge loss
When experienced employees leave, they take institutional knowledge, client relationships, and undocumented processes with them. This "brain drain" is the largest unmeasured cost of turnover, and the hardest to recover.
Team morale contagion
Gartner research shows that when a colleague resigns, the flight risk of remaining team members increases by 9-12% within six months. High turnover creates a cascading effect where departures breed more departures. Stabilizing turnover early prevents the compounding damage that turns a manageable 15% rate into a crisis-level 30%+.
Common Mistakes
❌ Only counting recruitment fees
Agency fees ($8,000-15,000) are the visible cost. The invisible costs, vacancy impact, team disruption, management time, and new hire ramp-up, are typically 2-3x larger than the recruitment fee alone.
❌ Not conducting exit interviews
Without understanding why people leave, you can't prevent future departures. Patterns in exit data (poor management, no growth path, below-market pay) reveal systemic issues that, once fixed, reduce turnover across the organization.
❌ Treating all turnover equally
Voluntary turnover of a top performer costs 3-5x more than losing an average performer, yet most companies report a single blended turnover rate. Segment turnover into regrettable (high performers you wanted to keep) and non-regrettable (poor performers or natural attrition) to focus retention efforts where they matter most.
