How do you calculate color match workload?

Divide the number of matches by the match rate per minute to get base hours, then multiply by one plus the allowance. With 18 matches at 0.12 matches/min and a 35% allowance, base time is 150 hr and estimated workload is 202.5 hr.

Why add a drawdown, cure, and approval allowance?

Because the bench match is only part of the job. Each match needs panels drawn down, cured, re-read, and often a customer approval loop. The 35% allowance here adds 52.5 hr on top of the 150 hr base.

What is a realistic color match rate per minute?

A rate of 0.12 matches/min means roughly one match every 8-9 minutes of active bench time, which fits straightforward solid shades. Metallics, pearls, and tight-tolerance organics run far slower.

How long does one color match take in this example?

At 0.12 matches per minute, one match averages about 8.3 minutes of base bench time; after the 35% allowance the effective time per match is roughly 11.25 minutes including drawdown and approval.

Should rush or hard matches use a different allowance?

Yes. A queue heavy with effect pigments or sub-0.5 dE tolerances can justify a 60-100% allowance because of repeated re-iteration and extended cure-and-read cycles.

Does this include instrument calibration and cleanup time?

Not explicitly. Fold routine calibration and bench cleanup into the allowance, or add it as separate fixed hours if it is a large share of your day.

Color Match Workload Calculator

Color Match Workload estimates the total lab hours a color-matching queue will consume once you account for the drawdowns, cure time, and customer approval cycles that stretch the raw matching time. Color chemists and tint-lab leads in coatings and ink production use it to staff and schedule the bench when a batch of new shades or revisions lands. It matters because the spectrophotometer reading is the fast part — the slow part is iterating, drawing down, curing panels, and waiting on sign-off. Sizing that real workload keeps the lab from over-committing on turnaround.

What this calculator does

Estimate color-match workload from requested matches, matches completed per minute, and allowance for drawdowns, spectro readings, and revisions.
scheduling formulation lab time for color matches and customer samples
It computes total color-matching hours from the number of matches, the per-minute completion rate, and an allowance for drawdown, cure, and approval overhead.

Formula used

Base color match workload = color matches or revisions ÷ color matches completed per minute
Estimated color match workload = base time × allowance factor

Inputs explained

Color matches or revisions required:
Color matches completed per minute:
Drawdown, cure, and approval allowance:

How to use the result

Use it when a block of color matches or revisions arrives and you need a credible hours estimate to schedule chemists or quote a turnaround.
It assumes a steady average match rate; a single difficult metallic or high-chroma organic match can take many times the average and skew a small queue.

Current U.S. benchmarks

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).
