Example calculations
Tap an example to prefill the calculator with sample values.
Moderate six-month attrition
120 staff, 14 departures, $18k replacement cost
A useful benchmark for HR teams pressure-testing annualized attrition and hiring budget impact.
Result: Turnover cost adds up quickly even before productivity drag is considered
High-churn service team
80 staff, 18 departures over four months
Operationally painful attrition where the annualized picture becomes much worse than the raw period rate suggests.
Result: Annualized turnover escalates sharply when churn stays concentrated in a short window
Stable professional team
40 staff, 2 departures in a year
A lower-turnover baseline for teams where replacement cost is high but exits are rare.
Result: Low attrition still carries a visible budget impact once replacement cost is priced properly
How the turnover estimate works
The calculator divides employee departures by starting headcount to get the period turnover rate, then converts that observation into an equivalent monthly attrition pace for annualization.
Replacement cost is modeled directly from departures multiplied by your cost-per-hire assumption so finance and HR can speak the same language about attrition impact.
Employee turnover FAQs
How the model annualizes attrition and translates it into replacement cost.
Why annualize turnover?
Because a short observation period can understate the true severity of persistent attrition. Annualizing shows what the current pace would imply over a full year if conditions do not improve.
What should replacement cost include?
Many teams roll together recruiting spend, onboarding time, manager time, training, lost ramp productivity, and sign-on incentives. The exact mix depends on the role.
Does this cover the cultural cost of turnover?
No. The model focuses on direct economic impact. Team disruption, morale drag, and customer impact can make real turnover cost materially higher.
