Should setup time count as productive use?

Use a consistent local definition. If productive use means making parts, exclude setup from the numerator and record it separately within available time.

Why can utilization not exceed 100%?

Productive hours are a subset of available hours. A higher numerator means the logs use different periods, fixtures or definitions.

Is 100% utilization always desirable?

No. Your target should allow the service and scheduling flexibility your work needs. The calculator uses your entered target without prescribing one.

Does low utilization prove I have spare capacity?

No. Low use can reflect missing demand, unsuitable fixtures or schedule conflicts. Confirm that the spare hours match the jobs you want to run.

Fixture Utilization Calculator

Measure productive fixture time as a share of available time. Use matching period logs and your fixture utilization target.

What this calculator does

Measure fixture utilization and the productive hours needed to meet your entered target.

Formula used

Fixture utilization = productive fixture hours ÷ available fixture hours × 100
Gap to target = target utilization − fixture utilization
Unused hours = available hours − productive hours
Productive hours at target = available hours × target utilization ÷ 100

Inputs explained

Productive Fixture Hours: Time logged making parts with this fixture during the measured period.
Available Fixture Hours: Time this fixture was available within the same measured period.
Target Fixture Utilization: Your planned productive share for this fixture and measured period.

How to use the result

Best suited to fixture time Review, shared workholder planning.
Utilization does not measure part quality or determine the production bottleneck. Different fixtures cannot share one availability denominator without a consistent aggregation.

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.
The producer price index for plastic resins and materials stands at 280.569 (BLS, Aug 2026), up 6.6% from a year earlier. Quotes priced off last quarter's material cost miss this move.
The U.S. has 14,378 furniture and related products establishments employing about 355,594 workers (Census County Business Patterns, 2023).
