Staff turnover rate calculator: rate and replacement cost.

Your turnover rate is the share of your team who left over a period. Put in three numbers and see your rate, plus what replacing those people cost. Then read what a healthy rate looks like.

The formula

Turnover rate = (people who left ÷ average headcount) × 100

Average headcount = (headcount at the start + headcount at the end) ÷ 2.
