Scrap and material yield calculator

Reconcile input material with good output using one consistent unit of measure. Add a material cost to estimate the value of calculated scrap.

Output: Good material yield, scrap quantity, scrap rate, and optional scrap cost.

APPLICATION NOTES

Use the result on the floor

Calculate material yield, scrap quantity, scrap rate, and optional scrap cost from input and good output. Keep the input boundary, unit definitions, and time period attached to any recorded result so another person can reproduce it.

Useful for

Estimate cut, trim, casting, or mixing yield.
Quantify the material value associated with scrap.
Compare actual yield with a planning assumption.

MODEL BOUNDARY

Assumptions and limitations

Assumptions

Input and output use the same mass, length, area, volume, or count unit.
Anything not in good output is classified as scrap for this simplified balance.
Optional cost is the value per entered material unit.

Limitations

The simple balance does not separate recoverable scrap, co-products, moisture change, work in progress, or measurement error.
Scrap cost excludes labor, overhead, disposal, and recovery value.

DECISION CHECK

Verify before changing the process

Do not use this simplified material balance for regulated environmental, financial, or inventory reporting without reconciliation to approved records and measurement methods.

REFERENCE

Frequently asked questions

What is material yield?

Material yield is good output divided by total input, expressed as a percentage.

Can I use kilograms or pieces?

Yes, provided input, good output, and cost all use the same unit basis.
