Employee Turnover Rate Calculator
Enter starting and ending headcount plus the number of departures to calculate the turnover rate and annualized retention rate for any period.

How does this calculator work?
Turnover Rate = Separations ÷ ((Start Headcount + End Headcount) ÷ 2) × 100. Annualize monthly figures by ×12, quarterly by ×4. Retention rate = 100% − turnover rate. US average is roughly 47% annually (BLS 2023) but varies widely by sector.
Formula
How this is calculated
Employee turnover rate measures how frequently staff leave and must be replaced, expressed as a percentage of the average workforce size over a given period. Average headcount — the mean of the opening and closing counts — smooths the figure when headcount changes due to seasonal hiring waves or layoffs and is the denominator recommended by SHRM (Society for Human Resource Management). Separations include all exits regardless of type: voluntary (resignations, retirements), involuntary (terminations, layoffs) and other departures. Dividing separations by average headcount and multiplying by 100 gives the period turnover rate.
When the measurement period is shorter than a year, the calculator annualizes the rate by multiplying by 12 (monthly) or 4 (quarterly) so it can be benchmarked against annual industry figures. The retention rate — simply 100 minus the turnover rate — is the complementary metric that many HR dashboards report alongside turnover.
US overall annual turnover averaged roughly 47% in 2023 according to Bureau of Labor Statistics data, but benchmarks vary enormously by sector: hospitality and retail routinely exceed 70–80% while finance and utilities often sit below 20%. Tracking turnover across consecutive periods reveals trends — a rising rate can signal engagement problems or compensation gaps long before they appear in employee surveys.
Frequently asked questions
It depends heavily on industry and role type. US average annual turnover is roughly 40–50%, but tech companies may target below 15% while hospitality may accept 60–80%. Benchmark against your own sector peers and monitor the trend over time — a sustained increase is the key warning signal, not any single absolute figure.
Average headcount — (start + end) ÷ 2 — is the SHRM-recommended method because it accounts for headcount changes during the period. Using only the starting count inflates the rate when the company has grown, and understates it when it has shrunk significantly.
Turnover counts all departures and typically assumes the vacated positions are eventually filled. Attrition measures only departures where the role is left unfilled — so the workforce intentionally shrinks. This calculator measures total turnover: all separations regardless of whether the position was backfilled.
