Formula and method
At $25 per hour for 40 hours across 52 weeks, gross wages are $52,000. Adding $5,600 in annual costs and subtracting 20 eight-hour absence days gives $30 per productive hour.
Cost per productive hour = (gross annual wages + additional annual costs) / (scheduled annual hours − absence hours)

Assumptions and limitations
- Scheduled hours assume 52 paid weeks and a five-day workweek. Each absence day removes one fifth of the weekly hours from productive time while remaining in gross paid wages.
- Add annual employer costs only once. Overtime is an additional cost entered directly; the calculator does not determine statutory overtime or payroll-tax rules.
- Enter nonnegative costs and absence days, positive productive hours and positive comparable annual revenue. Weekly hours cannot exceed 168.
- Revenue and all costs must cover the same scope and year. Labor-cost share can exceed 100% when modeled costs exceed revenue.
Common questions
Why does paid absence increase cost per productive hour?
Gross wages stay in annual cost while fewer productive hours remain in the denominator. Unpaid leave needs a different wage assumption.
