Voluntary turnover is when employees choose to leave (resignations, retirements). Involuntary turnover covers terminations, layoffs, and dismissals initiated by the employer. Voluntary rates signal engagement and competitiveness; involuntary rates reflect hiring quality and performance management. The BLS JOLTS report tracks 'quits' (voluntary) and 'layoffs and discharges' (involuntary) separately.

SHRM estimates 6-9 months of an employee's salary to replace them. For senior or specialized roles, total cost can reach 200% of annual salary. Costs include recruiting fees, advertising, interview time, onboarding, training, lost productivity during ramp-up, knowledge loss, and team disruption. A $95,000 employee can cost $47,500-$190,000 to replace.

BLS JOLTS data shows U.S. annual turnover averages around 18%, but varies widely: technology 13%, finance 12-15%, healthcare 17-20%, manufacturing 15-20%, and retail/hospitality 60-70%. Hourly-wage industries see far higher turnover than salaried professional roles. Benchmark against your specific sector, not the national average.

The Job Openings and Labor Turnover Survey (JOLTS) is a monthly U.S. Bureau of Labor Statistics release tracking job openings, hires, quits, layoffs, and discharges. It's the authoritative source for national and industry-level turnover trends. The 'quits rate' is widely used as a labor market confidence indicator—rising quits signal worker optimism.

Gallup's State of the Global Workplace research consistently identifies manager quality, recognition, growth opportunities, and engagement as top retention drivers. The Work Institute's retention reports cite career development, work-life balance, and manager behavior as leading reasons employees leave. Practical levers: competitive pay benchmarks, clear promotion paths, manager training, exit interviews to identify patterns, and stay interviews with high performers.

Yes, for comparison purposes. If you measure turnover over 6 months and get 8%, annualize by multiplying: 8% × (12/6) = 16% annual equivalent. This lets you compare against published annual benchmarks. Be cautious with very short windows (under 3 months) as seasonal hiring patterns can distort the projection.

Regrettable turnover is the loss of employees you wanted to keep—typically high performers and those in critical roles. Many HR teams track it separately because total turnover can be misleading: losing low performers is often healthy. Regrettable turnover above 5-8% usually signals serious retention problems regardless of overall rate.
