Turnover is easy to feel and hard to size. Put in your headcount and how many people left, and see your annualised rate against the 13% average.
Turnover rate = people who left during the period ÷ average headcount over that period. If the period is shorter than a year, we scale it up to an annual figure. We flag it against Mercer's 2025 US Turnover Survey (2,617 organisations), which put average voluntary turnover at 13%. Treat that as a general anchor, not a universal target — some sectors, like accommodation and food services, average over 50%. Read your number against your own industry and last year, not just the average.
