Employee turnover rate calculator
Turnover rate is the number of leavers divided by your average headcount, times 100. Six people leaving a team that averaged 50 over a year gives 12%. Enter your own figures below and you'll get the rate for the period, the monthly rate and a straight-line yearly figure.

How to use it
Step 1
Count everyone who left in the period for any reason: resignations, dismissals, retirements and contracts that ended. A move to another team inside the company isn't a leaver.
Step 2
Enter the headcount on the first day and on the last day. The calculator averages the two, so a hiring spree halfway through doesn't distort the rate.
Step 3
Enter the length of the period in months. Use 1 for a month, 3 for a quarter and 12 for a year.
Step 4
Read the monthly rate when you compare with a published monthly figure, and the yearly one when your board reports turnover per year.
Questions people ask
What is a good employee turnover rate?
Compare against a public yardstick rather than a guess. The US Bureau of Labor Statistics JOLTS survey put total separations at an average of 3.3% of employment per month in 2025. Set your own figure against that using this calculator's monthly rate, since the survey number is monthly, not yearly.
Why divide by average headcount and not the starting headcount?
Leavers come from everyone employed during the period, not only the day-one group. A team that grew from 40 to 60 had about 50 people who could have left. Dividing six leavers by 40 gives 15% instead of 12%, which overstates the rate by a quarter.
