The Cost of Employee Turnover: What Each Exit Really Costs
The cost of employee turnover is the total financial loss from replacing an employee who leaves. Gallup estimates the cost of replacing one employee at between one-half and two times their annual salary. Recruiting and onboarding are the visible costs. Lost output before the exit, lost institutional knowledge and the effect on the people who stay are harder to see and often larger.
A company with a $100,000 average salary that loses 15 people in a year faces a replacement bill between $750,000 and $3 million. That cost is spread across recruiting, payroll, lost output and management time, which makes it easy to miss as a single number.
This guide covers how much it costs to replace an employee, what a turnover cost calculation should include, how to run the numbers for your own organization and what the research says about the return on preventing departures.
How much does it cost to replace an employee?
Gallup’s 2019 research puts the cost of replacing one employee between one-half and two times their annual salary. The range is wide because it depends on seniority, how specialized the role is and which costs an organization chooses to count. Higher costs typically apply to senior and specialized roles.
Other estimates run lower. A 2012 review by the Center for American Progress found a typical (median) turnover cost of 21 percent of annual salary across positions other than executives and physicians. The gap between the two estimates reflects differences in the roles studied and the costs counted.
The list below applies the Gallup range to three salary levels. Treat these as illustrations of the range.
$60,000 salary: $30,000 at 50%, $60,000 at 100%, $120,000 at 200%
$100,000 salary: $50,000 at 50%, $100,000 at 100%, $200,000 at 200%
$150,000 salary: $75,000 at 50%, $150,000 at 100%, $300,000 at 200%
What counts in the cost of turnover?
A complete turnover cost calculation covers five categories.
Separation costs. Exit processing, final payouts and the management time spent on the departure itself.
Vacancy costs. The work that goes undone or gets redistributed while the seat is empty, plus any overtime or contractor spend to cover it.
Recruiting costs. Job postings, agency fees, interview time and the salary and benefits of the people running the search.
Onboarding and ramp-up costs. Training, supervision and the months a new hire takes to reach full productivity.
Pre-departure productivity loss. Performance often falls months before a resignation. A study published in the Journal of Management tracked 4,104 patent examiners who left the U.S. Patent and Trademark Office between 2001 and 2018. Their performance began to decline about six to seven months before they left. In their final six months, compared with their own earlier work, they approved 54% more patents with less scrutiny and cited 80% less prior research. The researchers note that the effect may be smaller in jobs where declining performance is caught and addressed quickly. Earlier research by Timothy Gardner, Chad Van Iddekinge and Peter Hom found that a larger-than-usual drop in productivity was one of a small set of behaviors that predicted voluntary quits within the following year. A salary-multiple formula does not capture this cost.
Two further costs resist measurement but are real: the institutional knowledge that leaves with a long-tenured employee, and the effect on the people who stay, who watch a respected colleague go and keep working inside the same structure.
How to calculate the cost of turnover (formula and example)
An employee turnover cost calculator needs only four inputs: the number of departures, the average salary of those who left, a replacement-cost multiplier and the time period.
Cost of turnover = number of departures × average salary × replacement-cost multiplier
Worked example: a company loses 15 employees in a year at an average salary of $100,000.
At a 0.5 multiplier: 15 × $100,000 × 0.5 = $750,000
At a 1.0 multiplier: 15 × $100,000 × 1.0 = $1,500,000
At a 2.0 multiplier: 15 × $100,000 × 2.0 = $3,000,000
Choose the multiplier by role. Use the lower end for roles that are quick to fill and quick to learn, and the higher end for senior or specialized roles. If you run the calculation by department, apply a different multiplier to each.
To see what standing still costs, multiply the annual figure by three. At a 1.0 multiplier, the example above comes to $4.5 million over three years with nothing changed.
Employee turnover cost calculator
Add a row for each group of roles that left. Enter how many people, their average salary, and a replacement-cost multiplier. Use a lower multiplier for roles that are quick to fill and quick to learn, and a higher one for senior or specialized roles.
Starting numbers are the worked example from the article (15 departures, $100,000 average salary). Replace them with your own.

Total cost, one year
$1,500,000
Three years, nothing changed
$4,500,000
Replacement cost (departures × salary × multiplier)$1,500,000
Formula: departures × average salary × replacement-cost multiplier. Multipliers run from 0.5 to 2.0 times annual salary, the range Gallup reported in 2019. The replacement figure does not include lost institutional knowledge or the effect on the people who stay, so the real cost runs higher than any calculation here.

Why the real cost runs higher than most calculations show
A formula built on salary multiples covers the cost of filling a seat. The costs around the departure need to be added separately.
Departures also tend to concentrate among the people who are hardest to replace. In her doctoral research, Dr. Annie Graziani found that working parents who leave unsupportive organizations are often among their strongest performers, because capability and options tend to go together. When the same kind of person keeps leaving, the pattern usually points to how the work is structured. [Link: RTO Mandates and Retention: Who Actually Leaves]
The research on working parents also suggests where that structure strains first. At the University of Pennsylvania, Dr. Graziani interviewed 35 working parents at U.S. organizations with 500 or more employees. In a follow-up survey of 25 of them, participants rated all six organizational supports she assessed as more important than they were effective, and childcare assistance showed the largest gap. [Link: Why Your Flexibility Policy Isn’t Improving Retention] Her working paper, “The Experience Gap,” proposes that employees carrying heavy demands outside work notice these gaps first, which makes them an early signal for the rest of the workforce.
What does preventing turnover return?
Two recent analyses put numbers on the other side of the ledger.
Boston Consulting Group and Moms First analyzed childcare benefits at five U.S. employers (Etsy, Fast Retailing, Steamboat Ski Resort, Synchrony and UPS) in March 2024 and found returns between 90 and 425 percent. BCG measured return as costs avoided each year.
A January 2024 Harvard Business School report by Joseph Fuller modeled the return on caregiver support using data from 97 corporate clients of a caregiving benefits provider. It estimated roughly 126 to 340 percent, depending on the assumed cost of replacing an employee and how far turnover falls. The estimates include savings from lower absenteeism and come from a model, not measured outcomes.
These are modeled and company-specific results, so they won’t predict any one organization’s return. Both found that the benefits paid for themselves once replacement costs were counted.
Gallup’s research also points to how much of this cost is avoidable. In a recent study of 717 people who had voluntarily left a job, 42 percent said their manager or organization could have done something to prevent it.
How to find out what turnover costs your organization
Pull last year’s departures. Start with voluntary exits only, with each person’s salary and tenure.
Apply a multiplier by role. Use the Gallup range and document why each role sits where it does.
Mark the avoidable exits. Identify the departures where an earlier conversation or a structural change could have altered the outcome.
Add the pre-departure loss. Estimate the months of reduced output before each resignation.
Project three years. Multiply forward with nothing changed, then compare against what a structural fix would cost.

Frequently asked questions
How much does it cost to replace an employee?
Gallup puts it between one-half and two times the employee’s annual salary. A 2012 Center for American Progress review found a typical cost of 21 percent of salary for most roles other than executives and physicians. The right figure for your organization depends on seniority, how specialized the role is and which costs you include.
How do you calculate the cost of turnover?
Multiply the number of departures by the average salary of those who left and by a replacement-cost multiplier between 0.5 and 2.0. Use higher multipliers for senior or specialized roles, and add an estimate of the productivity lost in the months before each resignation.
What is included in the cost of employee turnover?
Separation, vacancy, recruiting, onboarding and ramp-up costs, plus the productivity lost before the employee leaves. Institutional knowledge and the effect on remaining employees are real costs that rarely make it into the calculation.
Can turnover costs be reduced?
Yes. In a recent Gallup study, 42 percent of employees who left voluntarily said their manager or organization could have prevented it. Analyses by BCG and Harvard Business School found positive modeled returns on childcare and caregiving benefits.
