Formula used
(Normal hours × Hourly wage) + (Overtime hours × Hourly wage × Overtime multiplier) + (Setup hours × Setup rate) + Bonus pay
Direct labor wages × ((Benefits % + Payroll tax %) ÷ 100)
Direct labor wages + Employer burden + Indirect labor allocation
Units produced × (1 − Scrap % ÷ 100)
Total labor cost ÷ Units produced
Total labor cost ÷ Good units
Units per paid hour = Good units ÷ Paid hours
Units per productive hour = Good units ÷ Productive hours
(Base wages + Overtime wages) × Downtime %
This value is diagnostic only. It is already embedded inside paid labor cost.
How to use this calculator
- Enter paid hours, wage rate, and overtime details for the selected period.
- Add setup hours, benefits, payroll taxes, bonus pay, and indirect labor allocation.
- Enter downtime percentage to estimate hidden nonproductive labor cost.
- Enter scrap percentage and total units produced to calculate good units.
- Optionally enter selling price to see labor share of revenue.
- Press the calculate button to display the result above the form.
- Review the chart and export the result as CSV or PDF.
- Use multiple scenarios to compare staffing plans, output targets, or process improvements.
Example data table
| Scenario | Direct wages | Employer burden | Indirect labor | Units produced | Good units | Cost per good unit |
|---|---|---|---|---|---|---|
| Line A | $2,260.00 | $565.00 | $240.00 | 900 | 864 | $3.55 |
| Line B | $1,840.00 | $460.00 | $180.00 | 700 | 665 | $3.73 |
| Line C | $3,050.00 | $763.00 | $320.00 | 1,200 | 1,140 | $3.63 |
This table is illustrative. Your actual output depends on wages, burden rates, downtime, scrap, and support labor allocation.
Frequently asked questions
1. What does labor cost per unit show?
It shows how much paid labor is consumed by each produced or saleable unit. It helps compare pricing, staffing, productivity, and process performance across periods or product lines.
2. Why track both produced units and good units?
Produced units measure gross output. Good units remove scrap and rejects. Cost per good unit is usually more realistic because only acceptable units can be sold or passed downstream.
3. Should setup time be included?
Yes. Setup, changeover, inspection preparation, and staging consume paid time. Ignoring them makes labor cost per unit appear lower than reality, especially on short runs.
4. What belongs in indirect labor allocation?
Include supervision, material handling, quality support, schedulers, line support, and other labor that assists production but is not logged directly to each unit.
5. Does downtime create extra cost?
Downtime usually does not add a second cost line. It traps paid labor inside fewer useful units. This calculator reports downtime cost as an analytical indicator, not an added charge.
6. Why include benefits and payroll taxes?
Gross wages rarely represent the full employer cost. Benefits, insurance, leave, retirement, and payroll taxes can materially change the true labor cost per unit.
7. When should I use selling price in the calculator?
Use selling price when you want to estimate labor share of revenue. It helps reveal whether pricing still covers labor after burden, scrap, and support costs.
8. How can I reduce labor cost per unit?
Reduce downtime, shrink scrap, improve training, shorten setups, balance staffing, automate repetitive work, and raise throughput without creating overtime dependency or quality losses.
