Employee Turnover Rate: worked example
| Employees who left | 18 |
|---|---|
| Headcount at start | 120 |
| Headcount at end | 130 |
| Turnover rate | 14.4% |
| Average headcount | 125 |
Employee Turnover Rate: formula
Common error: Comparing a monthly rate with an annual one. A 2 percent monthly rate is not 2 percent a year, and annualizing it gives a much larger figure.
Employees who left counts all separations in the period, voluntary and involuntary, from HR records. Headcount at the start and end give the average headcount. Use a full year for an annual rate, or annualize a shorter period.
Decide whether to include layoffs, retirements and temporary staff and be consistent, since definitions change the figure. Track voluntary turnover separately to see who chooses to leave.

A separation count and a headcount count use different units: multiple people can leave the same position during a period. A turnover percentage alone does not identify reasons for departure or replacement costs. More departures than average positions can therefore produce a percentage above one hundred without an arithmetic error.
Compare the measurement interval and headcount convention before comparing two reported turnover rates.

Turnover compares the number of people who left with the size of the team, using the average headcount so that growth does not distort it. Eighteen departures from a team that averaged 125 people is 14.4 percent for the period. The same 18 leaving a team of 40 would be 45 percent, which is why the raw count alone says little.
Turnover depends on whether the separation count includes retirements, layoffs and seasonal staff.
Estimate the cost of a departure with the employee cost calculator, and the contractor versus employee page for staffing choices. The profit and break-even calculators show what turnover does to results. Exit interviews and stay interviews reveal causes better than rates do.
Does the example rate refer to a month or a year?
It refers to whichever consistent period the inputs cover. Eighteen departures divided by average headcount 125 gives 14.4% for that period.
Are the average headcount and exact staff exposure the same?
Not always. A two-endpoint average can miss large changes within the period; use a more detailed average when staffing varies.
What is a normal employee turnover rate?
Choose a comparison with the same industry, employment population, period and separation definition. Annual and monthly percentages are not directly interchangeable. Separate voluntary departures, involuntary departures and seasonal staffing so a change in the aggregate does not conceal the cause.
What does turnover cost?
Build the estimate from recruiting, vacancy coverage, onboarding, training and measurable lost output for the role. Avoid applying a universal salary multiple without supporting records. Some costs are direct cash outlays while others are productivity assumptions; show them separately.
How can I reduce turnover?
Improve management quality, pay competitively, offer growth paths and flexibility, and hire carefully. Exit and stay interviews show what matters.
