Keep the denominator visible
Average headcount smooths a growing or shrinking workforce better than using only the opening or closing snapshot.
Workforce analytics
Employee Attrition Rate Calculator
Measure workforce exits with a visible denominator, split voluntary from involuntary movement, annualize a shorter observation window and compare the period with your own planning target—without a universal “good” or “bad” label.
1 · Baseline & retention scenario
Regrettable share and save rate are employer-entered planning assumptions. Jobiba does not label individual employees or predict who will leave.

Break-even save rate
37.0%
14 exits against average headcount 125.0. Your scenario needs roughly 37.0% of the employer-defined regrettable cohort retained for the entered budget to break even on replacement cost alone.
3 · Reconcile a comparable follow-up cohort
After the follow-up period closes, enter observed regrettable exits from the same scope and the actual initiative spend.

This comparison does not prove the initiative caused retention. Cohort mix, labour market conditions, compensation changes, management changes and seasonality can affect exits. Use it to reconcile planning assumptions, not score individual employees.
Separate movement types
Two teams can have the same total attrition but very different voluntary and involuntary exit patterns. The split matters before choosing an action.
Treat annualization carefully
A partial-period annualized pace is useful for scenario planning, but it assumes the observed retention pattern continues.
Attrition rate FAQs
What is the employee attrition formula?
Attrition rate = departures during the period divided by average headcount, multiplied by 100. This calculator uses the simple two-point average of starting and ending headcount.
Are attrition and turnover the same?
The terms are often used interchangeably, but some organizations reserve attrition for positions that are not refilled. State your definition and use it consistently instead of assuming every benchmark uses the same policy.
Should voluntary and involuntary exits be combined?
A total rate can include both, but separating the exit types is more useful for diagnosis. Jobiba shows voluntary attrition separately while preserving the combined headline rate.
How does Jobiba annualize a partial period?
Jobiba compounds the observed retention pace across a year rather than simply multiplying the percentage by 12 or 4. Annualization is a scenario, not a forecast that the same pace will continue.
