Pricing a powder-coating job: the real cost per part

A powder-coating quote has more moving parts than "square footage times price": there's the coating material itself, the labour to prep and mask each part, a rack or setup fee that doesn't scale with the job size, and overspray or reject losses that mean you buy more powder than the bare part area. Skip any one of those lines and the job quietly stops paying for itself.

The method

Start with raw area = part surface area × number of parts. Overspray, reclaim losses and re-coats mean the powder you actually consume is higher than that raw area, so apply a waste allowance: coated area = raw area × (1 + waste % ÷ 100). Material cost is coated area × cost per square foot. Labour cost is prep/masking hours × your labour rate. Add a flat rack or setup fee and you get the total job cost. Divide by the number of parts for the cost per part. To price the job, divide total cost by (1 − target margin % ÷ 100) — that's a margin, not a markup, so the coating cost lands at (100 − margin)% of the price you quote.

A worked example

An order of 25 parts, each 10 sq ft of surface. Coating costs $0.95/sq ft, labour is $50/hour, prep and masking take 4 hours total, the rack/setup fee is $60, waste allowance is 15%, and the shop wants a 30% margin.

1. Raw area: 10 × 25 = 250 sq ft.
2. Coated area (with waste): 250 × 1.15 = 287.5 sq ft.
3. Material cost: 287.5 × $0.95 = $273.13.
4. Labour cost: 4 × $50 = $200.00.
5. Total job cost: $273.13 + $200.00 + $60 = $533.13.
6. Cost per part: $533.13 ÷ 25 ≈ $21.32.
7. Price at 30% margin: $533.13 ÷ 0.70 ≈ $761.61 — $30.46 per part.

Notice the price isn't cost plus 30% (that would be $533.13 × 1.30 = $693.07, a full $68.54 short of what a true 30% margin requires). Margin and markup answer different questions, and mixing them up quietly erodes the margin you think you're holding on every job.

Why the waste allowance matters

Waste isn't padding — it's the gap between the part's bare surface area and what actually gets consumed coating it, from overspray during application, reclaim losses in the booth, and the occasional re-coat on a rejected part. A shop that quotes off raw area instead of coated area is quietly eating that difference on every job; at 15% waste on a 250 sq ft order, that's 37.5 sq ft of powder — over $35 at this job's material cost — not billed to anyone.

What this doesn't include

This is coating material, direct labour, a setup fee, and a margin — nothing else. It doesn't include curing oven time or energy, masking supplies, part racking hardware, freight, or rejects that need a full re-strip and re-coat rather than a simple re-coat; add those as their own line items if your shop tracks them separately.
