When employee turnover begins to rise, the impact registers on two levels: the financial cost of replacing talent and the human cost of losing people. For HR leaders, understanding the full scope of the challenge is the foundation for meaningful action. This article covers what employee turnover is, the most common causes driving it, how to calculate and interpret your rate, and evidence-based strategies for strengthening retention through well-being investment.
A closer look at the definition.
Employee turnover is the rate at which employees leave an organization over a given period. Typically expressed as a percentage and measured monthly or annually, it provides you with a consistent metric for monitoring workforce stability. More than a data point, turnover reflects the health of an organization’s culture and the effectiveness of its talent strategies. For HR professionals revisiting the fundamentals, this definition is the foundation for understanding what comes next.
Let’s explore the types of employee turnover.
Not all employee turnover tells the same story, and treating it as a single metric can lead to incomplete conclusions. HR leaders gain a more accurate picture of workforce health by categorizing turnover by type. Different types signal different organizational challenges and call for different responses. The two primary distinctions are between voluntary and involuntary, and between desirable and undesirable.
Voluntary and involuntary turnover
Voluntary turnover occurs when employees choose to leave on their own terms, through resignations, retirements or decisions to pursue other opportunities. Involuntary turnover is employer-initiated, encompassing layoffs, terminations and role eliminations. While both types affect headcount, they tell different organizational stories. Voluntary departures often reflect unmet expectations or unaddressed needs, making them a more direct signal of gaps in culture, management and well-being. Tracking each type separately allows you to distinguish between strategic workforce adjustments and retention failures, and to focus your efforts where the most meaningful improvement is possible. Voluntary turnover can be an actionable metric for building a lasting retention strategy.
Desirable and undesirable turnover
Not all turnover is a warning sign. Desirable turnover refers to departures where the role and the person were not the right match, whether because performance expectations were not being met or because the fit was not there. These transitions can open space for stronger alignment on both sides. Undesirable turnover, by contrast, is the loss of high performers, tenured employees or colleagues whose institutional knowledge and specialized skills are difficult to replace. Understanding this distinction matters because the goal is not to achieve zero turnover. It is to reduce the type that erodes organizational strength, institutional memory and team effectiveness, while recognizing that some degree of natural workforce evolution is a sign of organizational health.
What are the main causes of employee turnover?
Exit interview data often surfaces reasons that feel straightforward: better pay, a new opportunity or a life change. But the underlying causes of turnover run deeper. Employees leave when their needs go unmet across the dimensions of well-being: physical, mental, social, financial and work. Diagnosing turnover effectively means looking beyond surface-level responses to the organizational conditions that made leaving feel like the right choice. Addressing root causes requires looking beyond compensation alone.
Burnout and chronic stress
Burnout is not a personal failing but a systemic signal that organizational demands have outpaced available support. When that mismatch becomes chronic, disengagement deepens and departure begins to feel like relief.
The 2026 WebMD Workplace and Employee Survey (n=3,872) illustrates how uneven burnout spreads across the workforce. Middle managers register burnout rates more than 3 times those of individual contributors, surpassing even senior leaders. Employees who strongly agree that AI makes them more productive carry a burnout risk 4.5 times higher than those who are neutral or disagree, a reminder that stress and burnout in the workplace can emerge from structural pressures you may not immediately anticipate.
Compensation and benefits gaps
When pay falls below market and benefits packages contract, employees begin to question whether their contributions are valued. The SHRM 2026 Employee Benefits Survey (n=5,472 U.S. organizations) highlights a telling pattern: employers rate healthcare (88%) and retirement (82%) as their most important benefit categories, while several offerings have narrowed. Financial wellness support is one area where that narrowing is visible. Employers rate 401(k) matches and bundled prescription drug coverage as less important than they did previously, and newer forms of support have yet to fill the space: only 10% of employers currently offer student loan repayment assistance. Taken together, the pattern suggests employees are receiving less financial support at a moment when they need more of it. For organizations navigating real budget constraints, that gap is also where the clearest opportunity sits: benefits employees can see, understand and use tend to signal value more effectively than headline numbers alone. Compensation matters, and so does whether employees feel their contributions are recognized.
Limited growth opportunities
Employees who cannot see a clear path forward within their organization will eventually look outside it. The absence of career development pathways, mentorship or skill-building opportunities communicates, often without a word spoken, that their future growth is not a priority. This is especially influential among high-performing employees, who are most at risk of seeking advancement elsewhere. Professional development functions as both a retention strategy and an engagement driver, with direct impact on the work dimension of well-being.
Leadership and management quality
The relationship between an employee and their direct manager is one of the strongest predictors of whether that employee stays or leaves. Poor communication, inconsistent recognition and unsupportive management behaviors erode trust over time, creating the disengagement that precedes resignation. Investing in leadership development is one of the highest-leverage retention interventions available to HR leaders.
According to the 2026 WebMD Workplace and Employee Survey, only 5% of employees who feel completely unsupported by their organization report high organizational trust, compared with 96% of those who feel fully supported. The gap between those two figures is where toxic work environments take hold.
Toxic workplace culture
When unsupportive management becomes the norm rather than the exception, the result is a culture where employees leave. A 2024 Monster Poll of more than 1,000 U.S. workers found that 61% would rather quit than continue in a toxic workplace, and 45% would accept a salary cut or demotion to escape one. Asked what was driving their poor mental health at work, 62% pointed to toxic culture and 53% to bad management.
For HR leaders, the signal is that culture-driven turnover will not be solved with compensation. It requires naming the specific behaviors that are tolerated, holding managers accountable for them and demonstrating through visible action that reporting concerns leads to change.
Low employee engagement
When employees show up but feel no emotional, cognitive or behavioral connection to their work or organization, that is low employee engagement, and it is a recognized leading indicator of turnover.
The 2026 WebMD Workplace and Employee Survey captures the scale: only 1 in 10 individual contributors report being highly engaged, 3 times lower than senior leaders, despite being the largest segment of the workforce. High-trust employees are 27 times more likely to be highly engaged than low-trust employees, reinforcing that engagement is inseparable from the broader well-being conditions organizations create, including purpose, belonging and meaningful work.
The real cost of high employee turnover.
The financial impact of high employee turnover is substantial and frequently underestimated. SHRM estimates that replacing an employee costs roughly 50% to 200% of their annual salary, depending on role and seniority, meaning the cost of a single departure in a senior or specialized role can be significant. But direct replacement costs account for only part of the picture. Indirect costs compound the damage: departing employees take institutional knowledge with them, team morale dips when colleagues leave, productivity slows during vacancy periods and the additional workload burden on remaining employees can accelerate further disengagement. Reviewing the full scope of employee turnover statistics makes clear why this is a strategic concern, not simply a recruitment challenge.
How to calculate your turnover rate.
The standard formula for calculating employee turnover rate is straightforward:
(Number of Separations ÷ Average Number of Employees) × 100 = Turnover Rate %
For example, if an organization had an average of 200 employees during a quarter and experienced 10 departures, the quarterly turnover rate would be 5% (10 ÷ 200 × 100).
For annual tracking, the same formula applies using 12-month figures. Monthly calculations allow for earlier detection of seasonal patterns or emerging trends. Many organizations also calculate voluntary and involuntary turnover separately, providing a more granular view of whether departures reflect individual choice, organizational restructuring or a combination of both. Tracking these figures over time builds a more actionable picture of workforce health.
What is a healthy employee turnover rate?
There is no universal answer to this question. Benchmarks vary significantly by industry, role type and organizational size, which means a rate that signals concern in one context may be entirely expected in another. A useful framework positions a healthy rate as low enough to preserve institutional knowledge and team stability, while high enough to allow for natural workforce evolution. Organizations that treat national averages as definitive targets risk missing the more meaningful signal in their own data. Tracking your organization’s turnover trend over time, segmented by voluntary and involuntary departures and by department, provides a far more actionable perspective than any single external benchmark.
How does turnover affect well-being?
Unmet well-being needs and elevated turnover risk are directly connected. Burnout, disengagement, poor mental health and financial stress are not isolated issues that happen to precede resignation. They are signals of a broader well-being gap that, left unaddressed, surfaces as voluntary departure. Well-being spans physical, mental, social, financial and work experiences, and these dimensions are interdependent. Neglecting one erodes the others.
According to the 2026 WebMD Workplace and Employee Survey, high well-being has fallen 11% since 2024, while low well-being has surged 39%, with more than 1 in 4 employees now reporting low well-being. Mental health, work, social and financial well-being are declining 3 to 4 times faster than physical well-being. Financial well-being has ranked lowest of all five dimensions for the third consecutive year. For HR leaders, these are indicators of where employees are most vulnerable and where retention risk is highest.
Strategies to reduce employee turnover.
Understanding why employees leave is the starting point. Acting on that understanding is where retention strategies take shape. Effective approaches address both the immediate drivers of turnover and the underlying well-being conditions that determine whether employees feel valued, supported and connected to their work. The strategies below are a starting point for organizations ready to reduce employee turnover through deliberate, evidence-based action.
Prioritize employee well-being.
If burnout and disengagement are systemic signals, the response has to be systemic too. Programs that ask employees to opt in to their own recovery leave the underlying conditions untouched. WebMD Health Services supports employees across physical, mental, social, financial and work well-being through programs that are personalized, accessible and built into how an organization operates—shaping workload, manager behavior and everyday culture rather than sitting alongside them as a standalone benefit.
The 2026 WebMD Workplace and Employee Survey highlights how closely these are linked: employees with high organizational trust are 5.7 times more likely to report strong well-being than those with low trust. Trust and well-being reinforce each other, and both shape whether employees choose to stay. WebMD ONE offers organizations a platform to build both.
Strengthen onboarding and early retention.
Effective onboarding sets the conditions for long-term retention. When new employees receive clear role expectations, build meaningful relationships early, connect with organizational culture from day one and gain timely access to the tools and resources they need, they are more likely to develop the commitment and confidence that sustain engagement well beyond the first year.
Build clear career development pathways.
Employees who can see a growth trajectory within their current organization are less likely to seek it elsewhere. Transparent career progression frameworks, skill development opportunities and internal mobility programs communicate that the organization is invested in their future. Career development conversations should begin early in an employee’s tenure and continue on a regular cadence throughout the year, not only at annual review time. For organizations aiming to retain their strongest talent, clear pathways forward are among the most persuasive retention tools available.
Listen, and act on employee feedback.
Gathering employee feedback through surveys, pulse checks and listening tools is a starting point. The retention value comes from how organizations act on what they hear. When employees see their input translated into visible action, trust deepens, engagement grows and the sense of powerlessness that often precedes voluntary resignation begins to recede. Closing the loop between feedback and response is a retention strategy in its own right. TINYpulse by WebMD Health Services helps organizations move from listening to acting, turning survey data into meaningful improvements that employees can see and feel.
How well-being programs support retention.
Structured well-being programs reduce turnover risk by creating the conditions employees need to feel seen, supported and motivated to stay. A platform addressing all five dimensions of well-being—physical, mental, social, financial and work—helps organizations respond to the root causes of disengagement rather than react to departures after they happen. Organizations that see the strongest retention outcomes treat well-being as an extension of their culture. WebMD Health Services partners with organizations to build programs that fit their workforce and reflect their values.
