What this tool does
Turnover is leavers divided by the average headcount, which is why a fast-growing team can show a low rate even while plenty of people leave. Annualising lets you compare a quarter with a year — a 4 % quarter is about 16 % a year. The inverse gives a rough average stay: 10 % annual turnover means people stay about ten years on average. Decide up front whether to count all leavers or only voluntary ones, and keep to it, because that choice changes the figure more than anything else.
Formula
turnover = leavers ÷ average headcount × 100 · annualised = turnover × 12 ÷ months
