Employee turnover cost calculator
What a departure really costs you, in three lines you can check.
Most turnover rates are wrong. The mistake is nearly always the same one. People divide by the wrong number. This tool divides by the average headcount for the period, never by the number left on December 31. It also splits people who quit from people who were let go, because those two mean different things.

Parental leave, disability leave and internal transfers are not departures. Under 50 employees, work over 24 months. On a small team one departure moves the number too far.
