Quick answer
Turnover rate = separations ÷ average number of employees × 100. 12 departures from an average headcount of 150 is an 8% turnover rate.
Enter the number of separations and the average headcount. The calculator returns the turnover rate.

Formula and method
Formula
Turnover rate = separations ÷ average number of employees × 100
IEEE-754 double precision; shown to the decimals indicated.
Use the same period and unit for both numbers.
Worked examples
These examples are verified: each one is an automated test case that the live calculator must reproduce exactly.
Example 1
Inputs: Separations = 12; Average number of employees = 150.
| Result | Value |
|---|---|
| Turnover rate | 8% |
Example 2
Inputs: Separations = 5; Average number of employees = 80.
| Result | Value |
|---|---|
| Turnover rate | 6.25% |
Example 3
Inputs: Separations = 30; Average number of employees = 400.
| Result | Value |
|---|---|
| Turnover rate | 7.5% |
The first line is the headline result (turnover rate). IEEE-754 double precision; shown to the decimals indicated.
Average headcount
Use the average of the start and end headcount for the period: (140 + 160) ÷ 2 = 150. Using only the final headcount overstates or understates the rate when the team changes size.
Interpretation
Turnover differs a great deal by industry, and some turnover (new talent) is healthy. Separate voluntary from involuntary exits, and look at early-tenure departures, which are costly. The period matters, so quote a monthly or annual rate.
How the result changes with separations
Holding every other input at the first worked example, this table changes only separations. It shows how sensitive the answer is to that one value; each row was produced by running this calculator.
| Separations | Turnover rate |
|---|---|
| 6 | 4% |
| 12 | 8% |
| 24 | 16% |
| 48 | 32% |
What happens with invalid input
These messages are produced by the calculator itself, so you know what to fix.
- Separations: entering "0" shows "Separations must be greater than 0." beside that field and no result.
- Average number of employees: entering "0" shows "Average number of employees must be greater than 0." beside that field and no result.

Background: business metrics
Business ratios depend on exactly which costs and revenues you include, so read each page's definition. Two common checks: break-even units = fixed costs ÷ (price − variable cost per unit), so $50,000 of fixed costs with a $10 price and $5 variable cost breaks even at 10,000 units; and net profit margin = net profit ÷ revenue, so $20,000 profit on $100,000 revenue is 20%.
Return on investment ignores time: 20% over five years is far less impressive than 20% in one, so compare returns over the same period.
Assumptions and limitations
- Denominator must be positive
If a required value is empty, not a number, or outside its allowed range, the form marks that field with a message and shows no result instead of a misleading number. The automated checks deliberately try invalid entries for separations and average number of employees to confirm this.
