Quality & Metrology calculator
Quality Technician Utilization Calculator
Measure inspection work as a share of available technician time. Enter person-hours for the same crew and period, then set your planned minimum inspection share.
What this calculator does
- Compare recorded inspection person-hours with matching crew availability and a user-entered allocation target.
Formula used
- Inspection utilization = 100 × inspection person-hours ÷ available person-hours
- Target inspection hours = available person-hours × target utilization ÷ 100
- Gap to target = 100 × (target inspection hours − recorded inspection hours) ÷ available hours
- Time outside inspection = available person-hours − inspection person-hours
Inputs explained
- Inspection Labor Hours: Matched crew inspection hours, recorded to 0.001 person-hour.
- Available Labor Hours: Matched crew availability including overtime, recorded to 0.001 person-hour.
- Target Inspection Utilization: Your minimum inspection allocation, entered to 0.001 percentage point.
How to use the result
- Best suited to technician workload review, inspection staffing allocation.
- Utilization does not measure inspection accuracy, speed or staffing sufficiency. This ratio does not distinguish the tasks outside inspection.
Current U.S. benchmarks
- As of Aug 2026, U.S. manufacturing runs at 75.7% of capacity (Federal Reserve via FRED), down 0.1 points from a year earlier. Enter your own plant's utilization; the national figure is a reference point for how loaded the industry is.
Common questions
- Is 100% inspection utilization the goal? Not necessarily. Technicians may also need time for calibration, investigations and training; enter a target suited to the planned role.
- Can inspection hours exceed available hours? No. Include any worked overtime in available hours so both entries use the same crew and time basis.
- Does idle machine time count as technician work? Only record technician person-time actually assigned to inspection. An unattended machine cycle is not automatically labor time.
- What if the crew had no available hours? Utilization and target gap are undefined at zero availability. Enter the matching available hours to complete the comparison.
