Why enter recorded writeoffs instead of unit price?

Writeoffs reflect the work actually lost when each unit was scrapped. A finished selling price includes amounts that were never incurred.

Can credits exceed scrap charges?

Yes. The resulting negative net amount is retained so you can reconcile the recorded recovery.

Are remaining units automatically good?

No. They are only the units outside the scrap count; they can include pending or reworked parts.

Why does cost per remaining unit become blank?

It has no denominator when every unit is scrapped. The recorded dollar totals still have a defined accounting meaning.

Quality calculator

Scrap Cost Calculator

Measure the recorded net cost of scrapped production. Enter matched unit counts, material and conversion writeoffs, disposal charges and realized recovery credits.

What this calculator does

Total recorded scrap losses and recovery credits, then relate the net loss to the production cohort.

Formula used

Gross scrap cost = material writeoff + conversion writeoff + disposal charges
Net scrap cost = gross scrap cost − recovery credits
Scrap rate = 100 × scrapped units ÷ produced units
Remaining units = produced units − scrapped units
Cost per remaining unit = net scrap cost ÷ remaining units

Inputs explained

Units Produced: Production count for the same completed disposition cohort.
Units Scrapped: Unique scrapped units from the disposition log.
Material Writeoff: Material book cost written off, entered in dollars to whole cents.
Conversion Writeoff: Labor and overhead writeoff, entered in dollars to whole cents.
Disposal Charges: Additional disposal charges, entered in dollars to whole cents.
Recovery Credits: Realized recovery credits, entered in dollars to whole cents.

How to use the result

Best suited to scrap disposition review, recovery credit reconciliation.
Unrecorded future claims and lost sales are excluded. This calculation does not establish whether remaining parts conform.

Current U.S. benchmarks

U.S. manufacturing runs at 75.7% of capacity (Federal Reserve, Aug 2026). New factory orders are up 8.5% year over year (Census).
