About this calculator
Powder coating cost is driven by surface area (which determines powder consumption via transfer efficiency), labor for hanging/masking/unhanging, and the fixed oven/booth operating cost amortized across a batch run. Powder transfer efficiency for electrostatic spray typically runs 60-80% for simple shapes and drops to 40-60% for complex geometry with recesses (Faraday cage effect), meaning a meaningful share of sprayed powder never lands on the part — reclaim systems recover some of this overspray but not all. This calculator estimates powder used from part surface area, coating thickness, and transfer efficiency, then adds labor and a per-batch oven/booth overhead allocation divided across batch size. Use it to quote finishing as an add-on service or to decide whether in-house powder coating beats outsourcing to a job coater at their per-part or per-pound pricing.

What each field means
Inputs
- Part surface area (in²)
- The part surface area used in the calculation, measured in in². Starts at 400 in² so you have a working example on load.
- Coating thickness (mil)
- The coating thickness used in the calculation, measured in mil. Starts at 2.5 mil so you have a working example on load.
- Transfer efficiency (%)
- The transfer efficiency used in the calculation, measured in %. Starts at 65 % so you have a working example on load. Accepted range: 10–95 %.
- Powder cost ($/lb)
- The powder cost used in the calculation, measured in $/lb. Starts at 6.5 $/lb so you have a working example on load.
- Hang/mask/unhang labor (min)
- The hang/mask/unhang labor used in the calculation, measured in min. Starts at 6 min so you have a working example on load.
- Labor rate ($/hr)
- The labor rate used in the calculation, measured in $/hr. Starts at 24 $/hr so you have a working example on load.
- Oven/booth overhead per batch ($)
- The oven/booth overhead per batch used in the calculation, measured in $. Starts at 45 $ so you have a working example on load.
- Parts per batch
- The parts per batch used in the calculation. Starts at 40 so you have a working example on load.

FAQ
What transfer efficiency should I assume?
Simple flat or box-shaped parts with good electrostatic ground typically hit 70-80% efficiency. Parts with deep recesses, tubing, or complex fixtures where the Faraday cage effect blocks powder from reaching inner corners often drop to 40-55%, even with post-cure touch-up spraying.
Does powder reclaim change this cost?
Reclaim systems recover 40-70% of oversprayed powder for reuse, effectively raising your usable transfer efficiency. If your booth has a working reclaim system, you can input a higher effective transfer efficiency to reflect that recovered powder, though reclaimed powder often gets blended at a lower ratio to maintain finish quality.
How does this compare to outsourcing to a job coater?
Job coaters typically price at $0.50-$3+ per part depending on size and complexity, or by the pound for large batches. Run this calculator for your in-house numbers and compare directly — outsourcing usually wins for low volume or occasional jobs, in-house wins once you have steady volume to keep the booth and oven utilized.
What's a typical coating thickness target?
Most functional and architectural powder coating specs call for 2-4 mils (dry film thickness). Thinner coats (under 2 mil) risk poor coverage and corrosion protection; thicker coats (over 5 mil) waste powder and can cause orange peel or edge coverage issues.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
