How do you calculate coating scrap cost?

Multiply scrapped parts by their value at scrap, then add sorting/documentation labor and replacement or expedite burden. Here 100 parts × $2.50 = $250, plus $150 labor and $75 burden, for $475 total.

What is the cost per piece in this example?

Total cost of $475 divided by 100 scrapped parts gives $4.75 per piece — nearly double the $2.50 bare part value once labor and replacement burden are loaded in.

Why value the part at scrap rather than at the blank cost?

By the time a coated part fails, it has absorbed pretreatment, powder or paint, oven energy, and handling. Valuing it as a bare blank understates the loss; use the loaded value at the point it failed.

Should rework be counted as scrap?

No — rework is recoverable and belongs in a rework-cost calculation. This tool is for parts that are truly scrapped. Mixing the two overstates scrap and hides the real reject mix.

What is a good coating scrap rate?

Mature powder and liquid lines typically target low single-digit scrap percentages. The dollar tool complements the rate: a 1% scrap rate on high-value coated assemblies can cost more than a 3% rate on cheap brackets, which is why cost per piece matters more than rate alone.

What goes in the replacement or expedite burden field?

The extra cost to make the customer whole on time: rush re-runs, premium freight, overtime to recover schedule, or buying replacement substrate. Here $75 covers the expedite premium on remaking the 100 parts.

Finishing calculator

Coating Scrap Cost Calculator

A coating scrap cost calculator adds up what scrapped finished parts really cost — the sunk value of the part at scrap, the labor to sort and document the reject, and the burden of replacing or expediting it. Finishing and quality leads use it to put a real dollar figure on runs lost to runs, sags, orange peel, contamination, or color mismatch, rather than waving at a reject bin. It matters because a coated reject carries far more value than a bare blank: it has already absorbed pretreatment, powder, oven time, and handling. Cost per piece makes scrap visible in the same units as your sell price, which is what gets a yield project funded.

What this calculator does

Calculate scrap impact from coating defects using scrapped parts, part value, labor, and overhead.
Use this calculator for practical powder coating or surface finishing planning, quoting, troubleshooting, or line setup.
It computes total coating scrap cost as scrapped-part value plus sorting/documentation labor plus replacement or expedite burden, and divides by quantity for cost per piece.

Formula used

Total cost = quantity × unit cost + labor/downtime + overhead
Cost per unit = total cost ÷ quantity

Inputs explained

Scrapped coated parts: undefined
Part value at scrap: undefined
Sorting and documentation labor: undefined
Replacement or expedite burden: undefined

How to use the result

Use it after a scrapped finishing run, in monthly scrap reviews, or when building the cost case for a yield-improvement or pretreatment project.
It values parts at a single per-part figure; if scrapped parts span different stages of value-add, run it per group rather than averaging.

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).
