Frequently Asked Questions

What is employee turnover and how is it measured?

Employee turnover is the rate at which employees leave and are replaced over a given period. Calculate it as: (Number of separations / Average headcount) × 100. For annual turnover of 20 people in a 200-person company: (20/200) × 100 = 10%. Always distinguish voluntary turnover (employees who chose to leave) from involuntary (terminations), and track regrettable vs. non-regrettable turnover separately. Losing underperformers is healthy; losing high performers is a business crisis.

What is a normal employee turnover rate?

Average annual voluntary turnover in the US is 15-20% across all industries. By sector: tech companies average 13%, healthcare 22%, retail 60%+. However, average isn't a good target,focus on regrettable turnover (high performers you didn't want to lose). A company with 8% total turnover that's losing all its top performers is in worse shape than one with 18% turnover that's losing only underperformers. Benchmark against companies of similar size and stage in your industry.

How do you reduce employee turnover?

Different causes require different solutions. (2) Fix manager quality (the #1 driver). (3) Market-agree compensation proactively. (4) Improve career path clarity. (5) Address cultural issues flagged repeatedly in surveys. (6) Identify flight risks 3-6 months before they resign using ONA and engagement analytics.
