How do I calculate employee turnover percentage?

Divide the number of employees who left by the average number of employees, then multiply by 100. Formula: (Separations ÷ Average Headcount) × 100. Average headcount is (Starting employees + Ending employees) ÷ 2. For example, if 10 people left from an average team of 100, the turnover rate is 10%.

What is a good employee turnover rate?

A turnover rate below 10% per year is generally considered healthy for most industries. Rates between 10–20% are moderate and common in retail or hospitality. Rates above 20–30% signal retention problems. Some industries like fast food or seasonal work naturally run higher. Always compare your rate to your industry benchmark.

What is the difference between voluntary and involuntary turnover?

Voluntary turnover is when employees choose to leave on their own — resignations, retirements, or personal reasons. Involuntary turnover is when the company ends the employment — layoffs, terminations, or dismissals. Both affect your overall turnover rate, but voluntary turnover is the stronger signal of engagement and satisfaction problems.

How do I calculate monthly turnover rate?

Use the same formula but limit your numbers to one month: (Monthly separations ÷ Average headcount that month) × 100. To convert a monthly rate to annual, multiply by 12. For example, a 1.5% monthly rate equals roughly 18% annually — though compounding means the true annualized figure may differ slightly.

What is the retention rate and how is it different from turnover?

Retention rate is the percentage of employees who stayed. Turnover rate is the percentage who left. They are not exact opposites because new hires during the period change your headcount. A simple retention rate formula is: ((Ending headcount − New hires) ÷ Starting headcount) × 100.

The Turnover Rate Formula

Employee turnover percentage tells you what share of your workforce left during a given period. The standard HR formula is:

Turnover % = (Separations ÷ Average Headcount) × 100

Average Headcount = (Starting employees + Ending employees) ÷ 2

For example, if you start with 100 people, end with 90, and 15 left during the year: Average = 95, Turnover = (15 ÷ 95) × 100 = 15.79%.

Retention rate is simply the inverse: Retention % = 100 − Turnover %

Turnover Rate by Industry

Industry	Typical Annual Rate	Signal
Technology	10–15%	Normal
Healthcare	15–25%	Moderate
Retail / Hospitality	30–60%	High but expected
Finance & Banking	8–12%	Low
Manufacturing	15–20%	Moderate
Education	10–16%	Normal
Nonprofits	18–25%	Moderate–High

Common Turnover Calculation Mistakes

Using a single headcount instead of average: Always average start and end headcount. Using only the starting or ending number skews the rate.
Mixing time periods: Monthly separations divided by annual average headcount gives a misleading result. Keep your numbers inside the same period.
Counting internal transfers as departures: Only count people who fully left the organization. Transfers, promotions, and role changes are not separations.
Ignoring new hires in the denominator: New hires during the period are included in the average headcount calculation, which is the correct approach.
Confusing turnover rate with attrition: Attrition usually refers to positions that are not backfilled. Turnover includes any replacement. Both metrics matter.

What High Turnover Costs You

Role Level	Typical Cost (% of Salary)
Entry-level / hourly	30–50%
Individual contributor	75–125%
Skilled professional	100–150%
Senior / manager	150–200%
Director / VP	200–250%
Executive / C-suite	300%+

Costs include recruiting fees, time-to-fill, onboarding, lost productivity, and institutional knowledge lost.

Frequently Asked Questions

Divide the number of employees who left by the average headcount, then multiply by 100. Average headcount = (start + end) ÷ 2. For example, if 10 people left from an average team of 100, your turnover rate is 10%.

For most office-based industries, below 10% per year is considered healthy. Between 10–20% is moderate. Above 20–30% indicates a retention problem worth investigating. Retail and hospitality naturally run higher — 30–60% is common there. Always compare your rate against your specific industry benchmark.

Voluntary turnover means the employee chose to leave — resignations, retirements, or personal reasons. Involuntary turnover means the company ended the employment — layoffs, terminations, or dismissals. Tracking both separately helps identify whether you have an engagement issue or a performance management issue.

Multiply the monthly rate by 12 for a simple annualized estimate. For example, a 1.5% monthly rate equals roughly 18% annually. For a more precise compound annualization, use: 1 − (1 − monthly rate)^12. A 1.5% monthly rate compounds to about 16.5% annually.

They are related but not identical. Turnover rate counts all departures, including those where the role was backfilled. Attrition usually refers to departures where the position was not replaced — headcount actually shrank. Both matter: turnover reveals replacement cost; attrition reveals workforce shrinkage.

Research commonly estimates replacement costs at 50–200% of the employee's annual salary, depending on role complexity. Entry-level roles tend toward the lower end; senior and specialized positions push toward the high end. Costs include recruiting, interviewing, onboarding, training, and the productivity dip during the learning period.

Retention rate is the percentage of employees who stayed. A simple formula: ((Ending headcount − New hires) ÷ Starting headcount) × 100. Note that turnover rate and retention rate are not exact opposites because new hires change your headcount during the period. A 15% turnover rate does not automatically mean an 85% retention rate.

Turnover Rate by Team Size and Separations

Quick reference: what turnover % results from different combinations of separations and average headcount.

Avg Headcount	2 leftturnover %	5 leftturnover %	10 leftturnover %	15 leftturnover %	20 leftturnover %	30 leftturnover %

Formula: Turnover % = (Separations ÷ Average Headcount) × 100. Green = below 10%, amber = 10–20%, red = above 20%.

Monthly Turnover Rate → Annualized Rate

How a monthly turnover rate converts to an estimated annual rate (simple ×12 and compound method).

Turnover Rate Facts & Rules of Thumb

Useful benchmarks and quick interpretations for common turnover scenarios.

Scenario	What It Means	Action Signal
Under 5% annual	Very stable workforce	Monitor for stagnation
5–10% annual	Healthy turnover range	Maintain current practices
10–20% annual	Moderate — watch trends	Investigate if rising
20–30% annual	High — retention risk	Exit interviews needed
Above 30% annual	Serious retention problem	Full HR review required
Over 5% monthly	Rapid workforce turnover	Immediate action needed
Voluntary > involuntary	Engagement / culture issue	Manager & culture review
Involuntary > voluntary	Hiring or fit problem	Review recruitment process
New hire turnover (90-day)	Onboarding failure	Redesign onboarding
Turnover in top performers	Critical talent flight risk	Compensation & growth review

No single number defines "good" turnover — context, industry, and growth stage all matter. Track trends over time, not just point-in-time rates.
