Example Data Table
Sample production log for comparing daily labor performance.
| Day | Total Output | Good Output | Paid Hours | Productive Hours | Net Productivity | Labor Cost | Cost per Good Unit |
|---|---|---|---|---|---|---|---|
| Monday | 420 | 408 | 64 | 58 | 7.03 units/hr | $1,460 | $3.58 |
| Tuesday | 435 | 426 | 66 | 60 | 7.10 units/hr | $1,520 | $3.57 |
| Wednesday | 460 | 448 | 68 | 63 | 7.11 units/hr | $1,575 | $3.52 |
| Thursday | 445 | 431 | 67 | 59 | 7.31 units/hr | $1,548 | $3.59 |
| Friday | 470 | 456 | 70 | 64 | 7.13 units/hr | $1,620 | $3.55 |
Formula Used
Productive Hours = Regular Hours + Overtime Hours − Downtime Hours − Rework Hours
Gross Productivity = Total Output ÷ Total Paid Hours
Net Productivity = Good Output ÷ Productive Hours
Labor Utilization = Productive Hours ÷ Total Paid Hours × 100
Quality Yield = Good Output ÷ Total Output × 100
Earned Hours = Good Output × Standard Hours per Unit
Labor Efficiency = Earned Hours ÷ Total Paid Hours × 100
Cost per Good Unit = Total Labor Cost ÷ Good Output
How to Use This Calculator

FAQs
1. What does labor productivity measure?
It measures how much accepted output a workforce produces for the labor time used. Higher values usually indicate better staffing efficiency, work methods, and execution consistency.
2. Why should I enter good output separately?
Good output excludes scrap, defects, and rejected work. That gives a more realistic productivity view because teams should be evaluated on accepted production, not just gross volume.
3. What is the difference between gross and net productivity?
Gross productivity uses all paid hours. Net productivity uses productive hours after downtime and rework losses. Comparing both helps identify hidden operational inefficiencies.
4. Should overtime be included?
Yes. Overtime increases paid labor time and may improve or reduce results depending on fatigue, disruption, and output quality. Including it makes the analysis more accurate.
5. What are earned hours?
Earned hours represent the standard labor time that should have been required for the accepted output. They are useful for comparing actual performance against a planned benchmark.
6. How should downtime be recorded?
Record waiting time, breakdowns, missing materials, inspections, and other nonproductive stoppages. Keep the same downtime rules across projects so comparisons remain meaningful.
7. What target productivity rate should I use?
Use a realistic benchmark from industrial engineering studies, historical site data, or contractual planning assumptions. The best target is measurable, repeatable, and specific to the task.
8. Can this calculator be used outside manufacturing?
Yes. It can support fabrication, installation, maintenance, field service, and repair work. Replace unit labels with tasks, meters, assemblies, or completed work packages.
