How to Calculate the Cost of Employee Turnover

Why the number matters

Turnover has a price, and most teams underestimate it because so much of the cost is hidden. When someone leaves, the visible line items (posting the job, interviewing, a signing bonus) sit next to a longer list of quieter losses: the vacancy itself, the ramp time before a new hire is fully productive, and the drag on the coworkers covering the gap. Putting a defensible dollar figure on all of that is what turns "we should retain people" into a budget case leadership can act on.

Before you build your own estimate, it helps to know the ranges the research supports. According to SHRM, the cost of replacing an employee can range from 50% to 200% of that employee's annual salary, depending on their level. Gallup puts the figure at one-half to two times the employee's annual salary, and calls that a conservative estimate. The Work Institute lands in a similar place, estimating the cost of employee turnover at 33% up to 200% of the departing employee's salary. Different methods, but the same message: replacing one person routinely costs a large fraction of a year's pay, and for senior roles it can cost more than the salary itself.

What goes into the calculation

A credible turnover cost splits into two buckets. The direct costs are the ones your finance system already tracks. The indirect costs are larger and harder to see, which is exactly why they get left out.

• Separation costs: exit administration, accrued PTO payout, and any severance.
• Recruiting costs: job advertising, agency or referral fees, recruiter time, and the hours your hiring managers spend screening and interviewing.
• Hiring and onboarding costs: background checks, equipment and setup, and the training time invested before the new hire contributes at full capacity.
• Lost productivity: the output missing while the seat is empty, plus the ramp period when the replacement is still learning the role.
• Coverage and morale costs: the overtime or stretched workload absorbed by the remaining team, and the risk that the strain pushes another person toward the door.

The ranges above are useful because they already fold these buckets together. When Gallup and SHRM cite figures that reach up to two times salary, the indirect costs are doing most of that work. If your own bottom-up estimate comes in well under half a year's salary, you have probably missed a category.

A simple method you can run this quarter

You do not need a perfect model to start. You need one that is consistent enough to compare roles and track over time.

• Pick a role, not a person. Group by job family and level (for example, front-line customer service, mid-level analyst, senior engineer). Costs scale with seniority, so a blended company-wide number hides the roles that hurt most.
• Anchor to annual salary. Take the role's fully loaded annual salary as your base. This is the denominator the published research uses, which lets you sanity-check your result against it.
• Add up what you can measure. Total the direct costs you can pull from records: advertising, recruiter and manager hours, onboarding, and any severance or payout.
• Estimate the productivity gap. Multiply the average days a seat stays empty, plus the ramp period, by the role's daily value. If you have no better figure, daily salary is a conservative floor.
• Express it as a percentage of salary. Divide your total by the annual salary. Now compare it to the benchmarks. For most roles a result inside the SHRM 50% to 200% band is reasonable. A junior role may sit near the Work Institute's 33% floor; a hard-to-replace senior role can exceed one salary and approach the top of the range.
• Multiply by your turnover volume. Cost-per-exit times the number of exits in that role gives the annual figure that belongs in a budget conversation.

What to do with the number

The point of the calculation is to change a decision. Once you can say what a single exit in a given role costs, retention spending stops looking like an expense and starts looking like avoided cost. A stay interview program, a manager coaching effort, or a pay adjustment only has to prevent a handful of departures to pay for itself when each one costs a large share of a salary.

Use the figure three ways. First, prioritize: focus retention effort on the roles where cost-per-exit and turnover volume are both high, since that is where the money is. Second, set a baseline and re-run the calculation each year, so you can show whether an intervention actually moved the number. Third, keep your assumptions written down and conservative. When you present a range grounded in SHRM, Gallup, and the Work Institute rather than a single precise-looking figure, the estimate is easier to defend and harder to wave away.
