Turnover rate formulas
Average headcount = (employees at start + employees at end) ÷ 2
Turnover rate = separations ÷ average headcount × 100
Annualized rate = period rate × 12 ÷ months in the period
Retention rate = (employees at start − separations) ÷ employees at start × 100
Example: a company starts a quarter with 120 people, ends with 130 and has 9 leavers. Average headcount is 125, the quarterly turnover rate is 9 ÷ 125 = 7.2%, and the annualized rate is 7.2% × 4 = 28.8%. Retention is (120 − 9) ÷ 120 = 92.5%.
The retention formula assumes every leaver was already on staff at the start. If some of the leavers were hired during the period, true retention of the original team is higher.

Frequently asked questions
What is the employee turnover rate formula?
Turnover rate = number of separations ÷ average number of employees × 100, where average headcount = (employees at start + employees at end) ÷ 2. For example, 9 leavers with 120 at the start and 130 at the end is 9 ÷ 125 = 7.2% for the period.
How do I annualize a monthly or quarterly turnover rate?
The usual method is to multiply by 12 and divide by the number of months in the period: a quarterly rate of 7.2% is 7.2% × 12 ÷ 3 = 28.8% per year. Adding up the 12 monthly rates gives the same kind of figure. The compounded method shown as an alternative gives a slightly lower number.
Who counts as a separation?
Any employee who left the organization during the period: resignations, dismissals, layoffs and retirements. Internal transfers and promotions are not separations. Most organizations count temporary and seasonal staff separately so they do not distort the rate.
What is the difference between turnover and retention?
Turnover counts how many people left relative to the average workforce. Retention looks at the people who were there at the start and measures how many of them are still there at the end. Because new hires can also leave within the period, the two do not always add up to 100%.
What is a good employee turnover rate?
It depends heavily on industry, role and region. Hospitality and retail often see much higher turnover than government or utilities. Compare your rate with your own history and with published figures for your sector, such as national labor statistics.
Why can the turnover rate be over 100%?
If more people leave during a year than the average number employed, for example in seasonal work with frequent re-hiring, separations exceed the average headcount and the rate goes above 100%.
