MihsabaHow to use
Calculate output per labor hour and per worker from period output, worker count and hours per worker.
- Enter matching-period inputs with consistent units: Output in one consistent unit, Number of workers, Working hours per worker
- Labor productivity = output ÷ (workers × hours per worker)
- Calculate, then check data definitions and assumptions in the note before comparing with another period.
How it is calculated
Example
Output of 960 units from four workers working eight hours each uses 32 labor hours: 30 units per labor hour and 240 units per worker for the period.
Important notes
Labor hours sum people’s hours, not factory elapsed time. For unequal shifts, enter actual average hours per worker so the product matches the true total. Output may be units, kilograms or comparable services. Do not compare different activities without matching units, quality and the hour definition. This ratio describes a shared process, not the performance of an individual worker.
Worked examples and interpreting results
Output of 960 units from four workers working eight hours each uses 32 labor hours: 30 units per labor hour and 240 units per worker for the period.
| Case | Calculation | Result |
|---|---|---|
| Labor hours | 4 × 8 | 32 |
| Hourly productivity | 960 ÷ 32 | 30 |
How to check the result

Frequently asked questions
Should I divide only by eight hours?
Four people working eight hours each contribute 32 labor hours. Dividing only by eight gives the process rate per elapsed hour.
How do I enter unequal working hours?
Sum all workers’ hours, divide by their count, and enter that average. The calculator reconstructs total hours.
Are the starting inputs my actual data?
They are only the worked example. Replace them with your data and press Calculate. Editing an input clears the old result.
