Quick answer: Employee turnover rate is calculated as (Number of Employees Who Left During the Period divided by Average Number of Employees During the Period) multiplied by 100. A healthy annual turnover rate is generally 10-15 percent for most industries, though retail and hospitality often run 30-50 percent. Use the calculator below to find your turnover rate and see how it compares to industry benchmarks.

How to Calculate Employee Turnover Rate
Turnover rate tells you what percentage of your workforce left during a given period, whether voluntary or involuntary. The formula is:
Turnover Rate (%) = (Employees Who Left / Average Number of Employees) x 100
Average headcount is used instead of just the starting count because it smooths out growth or shrinkage during the period.
Worked Example
A company starts the year with 100 employees and ends with 95. During the year, 12 employees left (including replacements hired).
Average headcount = (100 + 95) / 2 = 97.5
Turnover Rate = (12 / 97.5) x 100 = 12.3 percent
Turnover Rate Benchmarks by Industry
| Industry | Typical Annual Turnover |
|---|
| Technology / Software | 13-18% |
| Healthcare | 15-20% |
| Retail | 30-50% |
| Hospitality / Food Service | 40-75% |
| Manufacturing | 10-15% |
| Professional Services | 10-15% |
| Government / Public Sector | 5-10% |
Voluntary vs Involuntary Turnover
| Type | Definition | What It Signals |
|---|
| Voluntary | Employee resigns by choice | May indicate pay, culture, or growth issues |
| Involuntary | Employer terminates or lays off | May reflect performance management or restructuring |
| Retirement | Planned exit at career end | Usually neutral, plan for knowledge transfer |
| Regrettable | High performer leaves voluntarily | Highest priority to address in exit interviews |
Why Turnover Rate Matters
- Replacing an employee typically costs 20-33 percent of their annual salary once you include recruiting, onboarding, and lost productivity during ramp-up.
- High turnover in specific teams or managers often signals a management or culture problem worth investigating before it spreads.
- Comparing your rate against industry benchmarks (rather than an arbitrary target) gives a more realistic sense of whether your retention is a problem.
- Tracking turnover by tenure band (0-6 months, 6-12 months, 1-3 years) often reveals onboarding gaps if early-tenure turnover is disproportionately high.
Frequently Asked Questions
What is considered a good employee turnover rate?
Most industries consider 10-15 percent annual turnover healthy, since some turnover is normal and even beneficial (underperformers leaving, planned retirements). Rates significantly above your industry benchmark usually warrant investigation.
Should I include layoffs in turnover rate calculations?
Total turnover rate includes all separations, both voluntary and involuntary. Many companies also calculate voluntary turnover rate separately, since it more directly reflects employee satisfaction and retention issues.
How is turnover rate different from attrition rate?
The terms are often used interchangeably, but some organizations use “attrition” specifically for positions that are not backfilled (net headcount reduction), while “turnover” includes any separation regardless of whether the role is refilled.
What time period should I use to calculate turnover rate?
Annual turnover rate is the most common for benchmarking, but monthly or quarterly rates are useful for spotting trends earlier, especially in fast-growing or high-turnover industries like retail and hospitality.
Does new employee headcount growth affect turnover rate?
Using average headcount (start plus end divided by two) accounts for growth or shrinkage during the period, which keeps the rate meaningful even if you are actively hiring.
How much does employee turnover actually cost a company?
Estimates typically range from 20 percent of annual salary for hourly roles to 100-200 percent of annual salary for specialized or executive positions, once recruiting, training, and lost productivity are factored in.
What is a healthy turnover rate for a small business?
Small businesses often see slightly higher turnover than large enterprises due to fewer advancement opportunities, but staying within 15-20 percent annually is generally considered manageable.
How can I reduce voluntary turnover?
Common levers include competitive pay reviews, clearer career progression paths, better manager training, improved onboarding for new hires, and regular stay interviews with high performers to catch issues before they resign.
How to Calculate Turnover Cost, Not Just Rate
Turnover rate tells you how many people left, but it does not tell you what that departure actually cost the business. A more complete picture combines turnover rate with a cost-per-departure estimate. A commonly used rule of thumb from SHRM (Society for Human Resource Management) puts the average cost of replacing an employee at 6 to 9 months of that employee’s salary once you account for recruiting fees, advertising the role, interview time, onboarding, training, and lost productivity while the new hire ramps up to full speed.
For a rough estimate: multiply the number of departures by an assumed replacement cost percentage (20 percent of salary for lower-wage hourly roles, up to 100-200 percent for specialized or senior roles), then multiply by the average salary for those roles. A company with 12 departures at an average salary of 50,000 and a 30 percent replacement cost assumption would estimate roughly 180,000 in turnover-related costs for the year.
Tracking this cost figure alongside turnover rate helps make the business case for retention investments like better pay, management training, or improved onboarding, since a modest investment in retention often costs far less than the ongoing cost of high turnover.
Conclusion
Employee turnover rate is one of the clearest signals of workforce health, but it only becomes useful when compared against the right industry benchmark and broken down by voluntary versus involuntary separations. Use the calculator above to get your current rate, then use the benchmarks and tips in this guide to decide whether action is needed.
