How do you calculate powder coating cost per part?

Multiply good parts by the variable coating cost, add fixed masking/spray labor and oven overhead, then divide by good parts. With 250 parts at $1.75 variable, $126 labor, and $155 oven/overhead, the run totals $718.50, or about $2.87 per piece.

Why is my per-part powder cost higher on small runs?

Masking labor and oven overhead are fixed per run. Here $281 of fixed cost spread over 250 parts adds $1.12/part on top of the $1.75 variable — on a 50-part run that same $281 would add $5.62/part.

What is the variable coating cost per part?

It's the powder, gun consumables, and any per-part material that scales with quantity — $1.75/part in the defaults, totaling $437.50 of variable cost across 250 parts.

How does scrap affect powder coating cost per part?

Badly, because you divide by good parts only. If 250 parts coated but 25 failed, the same $718.50 spreads over 225 good pieces, pushing cost from $2.87 to about $3.19 each.

Should I coat in-house or send it out?

Compare the per-piece figure here against an outside coater's quote. In-house wins on large, repetitive runs where the $281 fixed base is well spread; outside coating often wins on small or infrequent batches.

What's a good powder coating cost per part?

It depends entirely on part size and batch, so use the breakdown rather than a flat benchmark. At $2.87 here, $1.75 is variable and $1.12 is fixed recovery — if your fixed share dominates, your batches are too small.

Finishing calculator

Powder Coating Cost Per Part Calculator

Powder coating cost per part is the all-in cost of a coating run divided by the parts that actually came out good, blending variable powder cost with the fixed labor and oven overhead of the job. Powder lines look cheap per pound, but masking labor and oven energy are charged whether you coat 50 parts or 500, so per-part cost swings hard with batch size and yield. Finishing estimators and job-shop owners use this to quote runs and to see how rejects and small batches inflate the real number. It matters because cure-oven energy and setup labor are committed the moment you fire the line, so a low-yield run silently raises the cost of every good piece.

What this calculator does

Combine powder, labor, cure energy, overhead, and run quantity into a powder coating cost per part.
Use for powder coating quotes, make-versus-buy checks, and product cost reviews.
It adds variable per-part coating cost across all good parts to the fixed masking/spray labor and oven/overhead, giving total run cost and cost per piece.

Formula used

Total coating cost = good coated parts × variable coating cost + labor + oven and overhead
Coating cost per part = total coating cost ÷ good coated parts

Inputs explained

Good coated parts: undefined
Variable coating cost: undefined
Masking and spray labor cost: undefined
Oven energy and overhead cost: undefined

How to use the result

Use it to quote a powder run, evaluate how batch size or scrap changes unit cost, or compare in-house coating against an outside coater's price.
It assumes one variable cost rate and counts only good parts, so it doesn't separately model rework, color-change purge, or rehang labor on rejects.

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).
