Units Per Labor Hour

A labor-productivity KPI. Define whether hours include indirect support and whether units are good-only or total produced.

UPH = good output ÷ direct labor hours.

Tip: Keep “Good Units” and “Labor Hours” on the same basis (period, units, and population) before calculating Units Per Labor Hour.

Units per labor hour (UPH) measures good output relative to direct labor hours.

Enter good units and labor hours for the same period and scope.

Understanding Units Per Labor Hour

How we calculate. UPH = good output ÷ direct labor hours. The form uses the same arithmetic as the worked examples on this page. See our methodology and accuracy policy.

Real-world scenario: A typical Units Per Labor Hour case uses good units 4800 and labor hours 160. Enter the same figures below to reproduce the worked path.

What is Units Per Labor Hour?

A labor-productivity KPI. Define whether hours include indirect support and whether units are good-only or total produced.

  • Good units preferred for quality-adjusted productivity
  • Labor hours = paid or clocked direct hours
  • Result is a rate, not a percent

The Formula

Units Per Labor Hour
UPH = Good units ÷ Labor hours

Worked Example

Scenario: 4,800 good units; 160 labor hours.
Step 1: 4800 ÷ 160 = 30
Answer: UPH is 30 units per labor hour.

Common Use Cases

  • Labor planning: staffing models
  • CI projects: productivity lift
  • Costing: labor content

Pro Tips

  • Normalize for mix complexity
  • Separate overtime spikes
  • Don’t hide scrap in “good”

Limitations: Units Per Labor Hour results are educational manufacturing and lean/TPM planning aids—not process-safety, quality-system, or financial advice. Confirm definitions with your MES/SCADA and quality policies.

FAQ

Direct labor only?

Usually yes for UPH. If you include indirect hours, label the metric so comparisons stay fair.

What if labor hours is 0?

UPH is undefined—enter positive labor hours.
