The cost of employee turnover is the total expense of losing someone and replacing them: separation costs, vacancy costs, hiring costs, onboarding and training, and the productivity lost while the new person gets up to speed. Gallup estimates that replacing an employee costs one-half to two times that employee’s annual salary, and calls that a conservative estimate (Gallup).
This guide breaks down each cost component, shows how to calculate turnover cost for your own organization, and explains how to use the result to decide where retention investments such as manager coaching are worth it.
The components of turnover cost
Turnover cost is easy to underestimate because most of it never shows up on a single invoice. Break it into five parts:
| Component | What it includes | Where to find the data | Often missed? |
|---|---|---|---|
| Separation | Exit processing, final pay items, any severance, knowledge transfer time | Payroll, HR time estimates | Sometimes |
| Vacancy | Overtime or contractors to cover the work, delayed projects, lost sales | Finance, team leads | Often |
| Recruiting | Agency fees, job ads, recruiter and interviewer time, assessments | Talent acquisition budget, calendars | Interviewer time often missed |
| Onboarding and training | Orientation, training programs, equipment, buddy and manager time | L&D, IT, manager estimates | Manager time often missed |
| Lost productivity | Ramp-up time for the new hire, reduced output before the departure, team disruption | Manager estimates of time to full productivity | Almost always |
How to calculate the cost of employee turnover
A practical formula for one role:
Turnover cost = separation + vacancy + recruiting + onboarding + lost productivity
To estimate lost productivity, multiply the new hire’s fully loaded pay for the ramp-up period by the share of productivity they are missing during it. For example, if a role takes six months to reach full productivity and people average about half productivity during that time, the lost productivity is roughly a quarter of a year’s loaded pay.
An illustrative example (hypothetical numbers, use your own):
- Role salary: $80,000; fully loaded cost about $100,000.
- Separation and knowledge transfer: $2,000.
- Vacancy coverage for two months through overtime and delays: $10,000.
- Recruiting, including interviewer time: $12,000.
- Onboarding and training, including manager time: $8,000.
- Lost productivity: six months at half productivity, about $25,000.
- Total: about $57,000, or roughly 0.7 times salary.
That lands inside Gallup’s range. Senior, specialized, or customer-facing roles usually cost more because vacancy and ramp-up effects are larger.
From one role to the whole organization
- Group roles into a few bands (for example frontline, professional, manager, senior leader).
- Estimate cost per departure for each band using the formula above.
- Multiply by the number of voluntary departures per band over the last year.
- Separate regretted from non-regretted turnover. The regretted part is what retention efforts can recover.
Many organizations find that a small number of teams account for a large share of the cost. That points to where to act first.
Is coaching worth it for retention? A cost-benefit frame
Once you know the cost of a departure, the break-even question becomes simple: how many departures does an investment need to prevent to pay for itself?
Break-even departures prevented = program cost / cost per departure
Using the illustrative figure above, a manager development or coaching program that costs $60,000 for a group of managers breaks even if it prevents about one regretted departure across their teams. Whether it will is an empirical question; measure regretted turnover for those teams before and after, and compare with similar teams that have not yet gone through the program. Our guide to coaching for employee retention explains how to set up that comparison.
Gallup also found that 52% of voluntarily exiting employees said their manager or organization could have done something to prevent their departure (Gallup). That suggests a meaningful share of turnover cost is recoverable, especially through manager behavior.
The hidden cost: broken agreements before people leave
Turnover cost formulas count what happens after someone resigns. They miss what happens before: months of lower effort while a person quietly disengages, often after a promise about growth, pay, or role was not kept. At DorWay we see organizations as Networks of Agreements™, and many resignations are the visible end of an agreement that broke much earlier.
Managers who make specific commitments, keep them, and renegotiate openly when plans change prevent many of those breaks. That is the practical side of accountability in leadership and integrity. For a broader view of options, see our comparison of employee retention strategies.
FAQ
How much does employee turnover cost?
Gallup estimates replacing an employee costs one-half to two times their annual salary. The actual figure depends on the role’s seniority, how long it takes to fill, and how long a new hire needs to reach full productivity.
How do you calculate the cost of employee turnover?
Add separation, vacancy, recruiting, onboarding and training, and lost productivity costs for a role. Multiply by the number of departures, and separate regretted from non-regretted turnover.
What is the biggest hidden cost of turnover?
Lost productivity: the reduced output before someone leaves, the gap while the role is open, and the ramp-up time for the replacement. It is often larger than recruiting costs.
Is there a turnover cost calculator I can use?
A simple spreadsheet with the five components in this guide works well. Fill in your own salary, time-to-fill, and ramp-up estimates for each role band, then multiply by your departures.
