Employee turnover
Definition
Employee turnover
Employee turnover is the rate at which workers leave a company over a set period, usually shown as an annual percentage of average headcount. It counts every departure, voluntary or involuntary, and is a direct read on how well a business keeps its people.
A healthy figure varies wildly by sector. The US Bureau of Labor Statistics put total separations across all industries at 3.3% a month in late 2024, while accommodation and food services ran closer to 4.9%, nearly double that pace.
The formula itself is simple: divide separations in a period by average headcount, then multiply by 100. What makes the number usable is the split into voluntary, involuntary, and regrettable exits, because each bucket points at a different fix.
Key takeaways
- Employee turnover divides separations in a period by average headcount, then multiplies the result by 100.
- US Bureau of Labor Statistics data put total monthly separations at 3.3% across all industries in late 2024.
- Gallup estimates replacing a salaried worker costs one-half to two times that person’s annual salary.
- Splitting turnover into voluntary, involuntary, and regrettable buckets turns a flat number into a decision.
- Mature offshore markets often post lower regrettable turnover because retention drives BPO margins directly.
How it works
Employee turnover is measured in three layers — a raw rate, a typology, and a cost figure — and each layer answers a different question. The rate says what happened, the typology says who left, and the cost figure says how urgent the fix is.
The raw rate uses one formula:
`Turnover rate (%) = (Separations during period ÷ Average headcount during period) × 100`
Run it monthly and annually. Most HR teams then sort separations into types, so leaders pull the right lever instead of reacting to a single blended figure that hides four different stories.
| Type | What it means | Typical lever |
|---|---|---|
| Voluntary | Employee chooses to leave (resignation, retirement) | Pay, growth, culture |
| Involuntary | Employer ends the role (layoff, dismissal) | Performance management, planning |
| Regrettable | A strong performer leaves voluntarily | Engagement, career path |
| Functional | An underperformer leaves voluntarily | Often a net positive |
| Early tenure | Departure inside the first 90 days | Hiring screen, induction |
The cost layer matters because turnover is rarely cheap. Gallup puts the replacement cost of a salaried employee at one-half to two times annual salary, once recruiting, induction, lost productivity, and team disruption are counted.
For a $60,000 role, that is $30,000 to $120,000 walking out the door each time someone resigns. Twenty such exits in a year turn a soft HR metric into a seven-figure line on the budget.
Tracking the rate next to employee engagement and employee retention gives you the whole picture. The rate tells you what is happening; engagement scores tell you why it is happening.
Segment before you act. Turnover in a night-shift voice team behaves nothing like turnover in a finance back office — and a single company-wide average hides both problems at once.
Benchmark against yourself first. A 20% annual rate in hospitality is unremarkable, while the same rate in a specialist engineering team usually means the pay band, the manager, or the career ladder needs attention.
Examples
Three dated cases show how employee turnover plays out across very different sectors, and how outsourcing partners absorb part of the shock. Each rests on a published figure rather than an industry rule of thumb, so you can check the working.
Amazon, US warehouses (2022). A New York Times investigation reported hourly warehouse turnover of roughly 150% a year, meaning it replaced its entire frontline workforce every eight months. Internal documents warned the available US labour pool could run dry by 2024.
Concentrix, Philippines operations (2023–2024). The contact-centre group, a major private employer in Manila and Cebu, cut voluntary attrition by roughly 18% year on year according to its 2024 annual report, after adding tiered career ladders and shift bidding.
NHS England (2024). The UK National Health Service, Britain’s publicly funded health system, recorded a 12.7% leaver rate among nursing staff in the year to March 2024, per official NHS Digital workforce statistics, down from 13.1%.
What links the three cases is timing. Amazon’s problem was structural, Concentrix fixed most of its gap with career design inside two years, and the NHS rate moved only slowly despite sustained national recruitment drives.
The pattern repeats across industries. Firms that move volume-heavy roles to mature offshore markets like the Philippines often report lower regrettable turnover, because BPO companies compete hard on retention — their margins depend on it.
Read the trend, not the snapshot. One quarter above target can be seasonal, but four in a row is a management problem, and public labour series exist so you can benchmark against your own sector rather than a national average.
Related terms
These adjacent terms sharpen what employee turnover actually measures and where it sits in the wider HR stack. Each one covers a slice of the same problem, so read them together rather than in isolation.
- Employee Retention: the inverse view, the share of staff a company keeps across a period.
- Employee Engagement: the motivational state that predicts whether a worker stays or starts job hunting.
- Attrition Rate: departures a company chooses not to backfill, so total headcount shrinks.
- Onboarding: the structured first 30 to 90 days that pushes early-tenure turnover up or down.
- Employee Compensation: the pay and benefits mix behind most voluntary quit decisions.
- Full-Time Employee (FTE): the headcount unit every turnover formula depends on.
- Outsourcing: the delivery model that shifts volume roles, and their turnover, to a specialist partner.
FAQ
What is a good employee turnover rate?
There is no universal number. Bureau of Labor Statistics figures showed all-industry annual turnover near 47% in 2023, while professional and business services sat closer to 38%. Anything below your own sector average is generally healthy.
How do you calculate employee turnover?
Divide separations during a period by the average number of employees in that period, then multiply by 100. Run the calculation monthly and annually, and report voluntary and involuntary departures separately so the trend stays readable.
What’s the difference between turnover and attrition?
Turnover counts every departure, including the roles you refill straight away. Attrition usually means departures where the seat stays empty or the role is cut entirely. Both shrink headcount, yet they signal very different strategies.
Why is employee turnover important?
It hits cost, productivity, and culture at the same time. Gallup puts the replacement cost of a salaried worker at half to twice their annual salary, and heavy regrettable turnover usually points at management, pay, or missing career paths.
Does outsourcing reduce employee turnover?
For volume roles it often does, because established providers in the Philippines and India invest heavily in retention their own margins depend on.
