Formula used
- Effective hourly rate = hourly rate, or salary ÷ hours per year
- Regular wages = rate × regular hours
- Bucket wages = rate × bucket multiplier × bucket hours
- Overtime premium = rate × (multiplier − 1) × hours (summed)
- Gross wages = regular wages + bucket wages + shift diff + bonus
- Burdens = selected rate × gross wages (taxes, benefits, overhead, etc.)
- Productivity loss = gross wages × loss factor (flat or weighted)
- Total cost = gross wages + burdens + allowances + fixed costs
- Baseline cost = same hours at base rate, no multipliers
- Overtime impact = total cost − baseline cost
