How do you calculate total process scrap cost?

Multiply scrapped weight by cost per pound, then add rework/labor and disposal/overhead. With 650 lb at $2.40/lb plus $420 rework and $300 disposal, material value lost is $1,560 and total scrap cost is $2,280.

What is scrap cost per unit?

It is total scrap cost divided by scrapped weight. In the example, $2,280 over 650 lb gives about $3.51 per pound, which is well above the $2.40/lb material price because rework and disposal add roughly $1.11 per pound.

Why is scrap cost per pound higher than the material price?

Because material is only part of the cost. The $720 of rework, disposal, and overhead adders spread across 650 lb add about $1.11 per pound on top of the $2.40 raw price, giving $3.51 per pound fully loaded.

What is a good scrap cost target?

Most plants track scrap as a percent of material cost or revenue and aim for the low single digits. The dollar target depends on volume, but any scrap stream where disposal and rework exceed the material value is a priority for a countermeasure.

Should disposal cost really be included?

Yes. For hazardous or regulated material, disposal and overhead adders often approach or exceed the material value, so excluding them badly understates the true cost and can misrank improvement projects.

Scrap cost vs. rework cost, what is the difference?

Rework cost is what you spend to save salvageable material and is one input here. Scrap cost is the total loss when material cannot be saved, including the material value itself plus disposal, so scrap is generally the more expensive outcome.

Process Manufacturing calculator

Process Scrap Cost Calculator

Process scrap cost is the fully loaded dollar value destroyed when material is scrapped, going beyond the raw material to include the rework, labor, disposal, and overhead that the scrap event also consumes. Plant controllers, continuous-improvement leads, and process engineers use it to put a real number on quality problems so projects can be prioritized by dollars, not gut feel. In chemical, coating, and material-conversion plants, scrap often carries hazardous-disposal fees that dwarf the material value, which is exactly why the per-unit figure matters. This calculator returns both the total scrap cost and the cost per pound so you can compare scrap events on an apples-to-apples basis.

What this calculator does

Estimate process scrap cost from scrapped volume or mass, variable cost, labor, and disposal adders.
costing scrap, yield loss, or rejected process material for a batch or campaign
It multiplies scrapped material weight by cost per pound, adds rework/labor and disposal/overhead adders, and returns total scrap cost plus cost per pound.

Formula used

Total scrap cost = scrapped material × cost per unit + rework and labor + disposal adders
Scrap cost per unit = total scrap cost ÷ scrapped material

Inputs explained

Scrapped process material weight:
Material value or purchase cost:
Rework, handling, and labor cost:
Disposal and overhead adders:

How to use the result

Use it when quantifying a scrap event, building a cost-of-poor-quality case, or comparing the true cost of scrap across products or lines.
It assumes the entered adders are complete; hidden costs like lost capacity, expedite freight, or customer penalties are not captured unless you add them.

Current U.S. benchmarks

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).
