How do you calculate booth utilization?

Divide the hours the booth was actively spraying by the total hours it was available, then express as a percentage. With 8 spray hours out of 250 available, utilization is 3.2%, leaving a 91.8-point gap to a 95% target.

What is a good utilization rate for a thermal spray booth?

High-performing single-shift booths often run 60-80% utilization; multi-shift operations can push higher. A world-class target near 95% is aggressive and usually needs disciplined changeovers and steady order flow.

Why is my booth utilization so low?

Low utilization usually reflects gaps in the order book, long changeovers, waiting on masking or inspection, or measuring against a large available-hours base. A 3.2% result signals the booth was available far longer than it was actually spraying.

What does the gap to target mean?

It is the difference in percentage points between your current utilization and your target. Here 95% target minus 3.2% actual leaves a 91.8-point gap, the improvement runway before you hit target.

Should I add a booth if utilization is high?

High sustained utilization near or above target, combined with a healthy backlog, is a strong signal for added capacity. But confirm the work is profitable first; utilization measures busyness, not margin.

Utilization vs throughput: what is the difference?

Utilization measures the share of available time the booth is spraying; throughput measures parts per hour while it runs. A booth can have high throughput but low utilization if it sits idle much of the day.

Thermal Spray, Hardfacing & Wear Coatings calculator

Booth Utilization Calculator

A thermal spray booth is a capital-heavy asset with hoods, dust collection, robots and acoustic enclosure, so idle booth time is expensive. This calculator expresses active spray hours as a percentage of available booth hours and shows the gap to your utilization target. Plant managers, capacity planners and lean teams use it to see how hard the asset is really working and whether a second shift or a new booth is justified. A booth that looks busy on the floor can still post surprisingly low utilization once changeovers, waiting and maintenance are subtracted.

What this calculator does

A thermal spray booth is a capital-heavy asset with hoods, dust collection, robots and acoustic enclosure, so idle booth time is expensive.
Use it when booth utilization in thermal spray, hardfacing and wear coatings needs a clean rate and gap-to-target you can put on a tier board.
It computes booth utilization as active spray hours divided by total available hours, and the point gap between that rate and your target.

Formula used

Booth Utilization rate = affected amount ÷ total amount
Gap to target = target rate - calculated rate

Inputs explained

Booth hours actually spraying:
Total booth hours available:
Target booth utilization rate:

How to use the result

Use it when reviewing asset utilization, justifying capital or shift changes, or benchmarking one booth against another.
Utilization alone does not judge whether the work being run is profitable; a fully utilized booth running low-margin parts is still a business problem.

Current U.S. benchmarks

As of May 2026, U.S. manufacturing runs at 75.6% of capacity (Federal Reserve via FRED), up 0.2 points from a year earlier. Enter your own plant's utilization; the national figure is a reference point for how loaded the industry is.
Industrial electricity averages 8.66 cents per kWh across the U.S. (EIA, Apr 2026), up 5.5% from a year earlier. Energy-intensive steps carry this directly into unit cost.
The producer price index for industrial chemicals stands at 344.336 (BLS, May 2026), up 16.1% from a year earlier. Quotes priced off last quarter's material cost miss this move.
The U.S. has 14,543 chemical manufacturing establishments employing about 911,245 workers (Census County Business Patterns, 2023).
