How the math works
Cost-per-hire is the number everyone tracks; the cost of the seat sitting empty is the bigger one nobody prices. Here's the honest net math the kit runs on every open role.
The inputs (2 roles open 45 days)
Two roles open for 45 days quietly cost $78,692 in net lost revenue — roughly $1,615 for every extra day they stay empty. The kit prices each open seat so a stalled hire stops looking free.
Revenue-per-employee method: gross impact minus the salary you're not paying while vacant, plus temp/overtime. Hard revenue only — burnout and morale aren't counted, and the figure is only as honest as the impact factor you set.
