Employee Turnover Rate Calculator
Calculate turnover as separations ÷ average headcount, split into voluntary and involuntary, annualised from any period, with replacement cost.
| Measure | This period | Annualised |
|---|---|---|
| Separations | 15 | 180.0 |
| Turnover rate | 7.14% | 85.71% |
| Replacement cost | $60,000.00 | $720,000.00 |
An annualised rate above 40% is very high outside hospitality, retail and contact centres, where it is close to normal. Check whether the losses cluster in one team or in the first 90 days.
Turnover is separations ÷ average headcount × 100, where average headcount is (beginning + ending) ÷ 2 — the standard HR definition. The annualised column multiplies the period rate by 12 ÷ period months, which assumes the rest of the year behaves like the period you entered; a single bad month can look alarming when scaled up. The retention rate here is 100% minus turnover, which is an approximation: a true retention rate counts only employees present for the whole period, so it differs when you hire and lose people inside the same period. Replacement cost is separations × your cost per hire, an estimate that varies widely by role and seniority. Everything is worked out in your browser and no headcount data leaves your device.
What is the Employee Turnover Rate Calculator?
Employee turnover is separations divided by average headcount, where average headcount is the beginning figure plus the ending figure divided by two.

About the Employee Turnover Rate Calculator
Employee turnover is separations divided by average headcount, where average headcount is the beginning figure plus the ending figure divided by two. This calculator applies that standard definition, splits the result into voluntary and involuntary turnover, and shows the retention rate alongside it.
Because a monthly figure and an annual figure are not comparable, it annualises: pick the period your numbers cover and the tool scales the rate to a twelve-month equivalent so you can benchmark honestly. It also estimates the cost of the churn from your own cost-per-hire figure, for the period and annualised.
An interpretation note puts the annualised rate in context without pretending there is one right answer — 30% is alarming in professional services and unremarkable in hospitality or contact centres. The retention figure is labelled as the approximation it is rather than presented as exact. Everything runs in your browser and no headcount or payroll data ever leaves your device.
Frequently asked questions
How do you calculate employee turnover rate?
Divide the number of separations in the period by the average headcount, then multiply by 100. With 15 leavers and an average headcount of 210, turnover is 7.14% for that period. Average headcount is the starting figure plus the ending figure divided by two.
What is a good employee turnover rate?
It depends heavily on the sector. Under 10% annualised is low, 10–20% is what most mixed workforces see, and above 40% is normal in hospitality and contact centres but a serious warning sign in professional roles. Compare against your own industry and your own history.
How do I annualise a monthly turnover rate?
Multiply the period rate by 12 divided by the number of months it covers, so a monthly rate is multiplied by twelve. Bear in mind this assumes the rest of the year behaves the same way — one bad month scaled up can look far worse than reality.
What is the difference between voluntary and involuntary turnover?
Voluntary turnover is people choosing to leave — resignations and retirements — and usually points at pay, management or career progression. Involuntary turnover is dismissals and redundancies, which points at hiring quality or business conditions. Tracking them separately is what makes the number actionable.
How is retention rate different from turnover rate?
A true retention rate counts only employees present for the entire period, so it is not simply the mirror of turnover once you hire and lose people in the same window. This tool reports 100% minus turnover as an approximation and says so, rather than presenting it as exact.
