How do I calculate masking labor cost?

Parts × minutes per part ÷ 60 × loaded rate, plus the job setup. At the defaults, 100 parts at 4.5 minutes and $32 an hour is 7.5 hours, $240 of variable labor and $390 total, or $3.90 a part.

Should unmasking time be included in the minutes?

Yes, every plug and tape run comes off after cure, often with residue cleanup, at the same bench and rate. Timing only the masking direction understates the block by a third or more on tape-heavy work.

Why does masking cost so much on short runs?

The setup does not shrink: print, staging and first-article approval cost the same for 20 parts as for 500. At the defaults that setup is $1.50 of the $3.90 per-part figure and dominates a short run.

When does a custom mask or fixture pay off?

When minutes saved × loaded rate × annual volume beats its cost. Cutting a 12-minute part to 7 saves $2.67 a part at $32 loaded, so an $800 die pays back inside about 300 parts.

Masking Labor Cost Calculator

Find what masking costs a job in hours and dollars, including the setup that short runs cannot spread. You need the parts masked, stopwatch minutes to mask and unmask one part, the loaded rate and the batch setup.

What this calculator does

Masking labor for a job from stopwatch minutes per part, the loaded rate and the one-time setup.

Formula used

Masking hours = parts masked × mask-and-unmask minutes ÷ 60
Variable labor = masking hours × loaded labor rate
Total masking labor = variable labor + job setup cost
Masking labor per part = total masking labor ÷ parts masked

Inputs explained

Parts Masked: Parts in the job that need masking before coating.
Mask and Unmask Minutes per Part: Stopwatch minutes to mask one part and strip it after cure.
Loaded Labor Rate: Loaded masking bench rate: wages plus taxes, benefits and overhead.
Job Setup Labor Cost: Per-job setup: masking print, staging plugs and first-article approval.

How to use the result

Best suited to quoting masking as its own price line, scheduling bench hours beside spray and cure, justifying die-cut masks on complex work.
Masking failures (coated threads, stripped datums) are priced with defects, not here. Averages hide the learning curve on new work; re-time when the masking method changes. Custom masks or fixtures that cut minutes are a capital decision this page informs.

Current U.S. benchmarks

As of Sep 2026, average hourly earnings in U.S. manufacturing are $30.21 (BLS), up 3.4% from a year earlier. Burdened shop rates typically run 1.3 to 1.8 times earnings once benefits and overhead are loaded.
Industrial electricity averages 9.77 cents per kWh across the U.S. (EIA, Jul 2026), up 4.7% from a year earlier. Energy-intensive steps carry this directly into unit cost.
The producer price index for industrial chemicals stands at 336.006 (BLS, Aug 2026), up 13.3% 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).
