Employee attrition & utilisation

Business Model & Unit Economics · Unit metrics

What it is

The rate at which employees leave, and the share of their available time that is billable or productive. In people-intensive businesses the two together determine both cost and delivery capability

High attrition raises recruitment and training cost while eroding client knowledge

Impact on industries

  • Utilisation is a direct profit lever in services - a few percentage points move margin materially with no pricing change
  • Attrition is expensive beyond replacement cost, since departing staff take client relationships and undocumented knowledge
  • Pushing utilisation too high causes burnout and then attrition, so the two metrics work against each other past a point
  • Some attrition is healthy, and a very low rate in a growing business can indicate weak performance management
