Employee Turnover Rate Calculator

Divide leavers by average headcount to get the turnover rate for the period.

About Employee Turnover Rate Calculator

The turnover rate is the share of average headcount that employees who left represents, expressed as a percentage. The same figure is also shown per 1,000 and as a "one in every N" odds statement, which is easier to reason about when the rate is very small. Absolute counts hide scale — a rate normalises the number so you can compare periods, channels or cohorts of different sizes, where lower is better.
