Attrition Rate Calculator

Calculate employee attrition and retention rates for a given period.

Employees at start of period

Employees at end of period

Number of separations

Attrition rate measures separations relative to the average workforce over the period.

We compute average employees as (start + end)/2 and then the attrition percentage from separations.

If you start with 200, end with 185, and have 25 separations, the attrition rate will be shown above.

Different organizations may report separations or turnover differently; this is a standard measurement.
