In typical client practices, average turnover rate (the number of staff who leave each year divided by the total staff count) is about 25%. Practices actively working to improve this figure can typically achieve 15%. In chronically lower-morale settings or practices with weak hiring habits, annual turnover rate can be 35% or higher. The highest U.S. turnover rate we’ve seen recently in our consulting practice was 75%, registered for two years back-to-back. We’ve seen more than 100% overseas.
