How do you calculate roll scrap cost?

Multiply scrapped length by value per meter by the unrecoverable share, then add the handling fee. For 1,200 m at $0.85/m, 80% unrecoverable plus a $120 fee: 1,200 × 0.85 × 0.80 = $816, plus $120 = $936 total.

Why multiply by the unrecoverable share?

Because reclaimable web isn't a total loss. If 80% is unrecoverable, only that portion is truly written off; the other 20% can be reground, reclaimed or sold off-grade, so it doesn't count at full value.

What is cost per scrapped meter?

Total scrap cost divided by scrapped length. Here $936 over 1,200 m is $0.78 per meter, higher than the $0.85 raw value times 80% because the fixed $120 handling fee is spread across the length.

How do I lower roll scrap cost?

Reduce meters scrapped, improve the reclaim rate to cut the unrecoverable share, or negotiate the disposal fee. The variable portion ($816) dominates here, so cutting scrapped length returns the most.

Should the handling fee be per event or per ton?

Enter it as the total fee for this scrap event. If your hauler charges per ton, convert it to a dollar figure for the amount of web in this calculation before entering it.

Does this include lost margin or just material cost?

Just the material and disposal cost. It does not capture lost sales margin or the production time consumed making web you then threw away, those are separate, often larger, costs.

Nonwoven Materials & Technical Textiles calculator

Roll Scrap Cost Calculator

Roll scrap is the most visible waste on a nonwovens floor, but its true cost is more than the material, it's the unrecoverable fraction plus the fee to haul it away. This calculator puts a dollar figure on scrapped web so cost engineers and production managers can prioritize which scrap source to attack first. Because some nonwoven trim and off-spec web can be reclaimed or sold off-grade, the unrecoverable share matters as much as the meters lost. Knowing cost per scrapped meter also lets you compare scrap events on an apples-to-apples basis across products.

What this calculator does

Estimate the value lost to edge trim, off-spec and threading scrap on a nonwoven roll line.
A converting supervisor quantifies scrap exposure on a slitting and winding run to judge whether trim losses justify a process change.
It computes the total cost of a scrapped roll by valuing only the unrecoverable portion of the material and adding the waste handling fee.

Formula used

Scrap cost = scrapped length x value per meter x unrecoverable share% + handling fee
Cost per scrapped meter = total scrap cost / scrapped length

Inputs explained

Scrapped roll length:
Material value per scrapped meter:
Unrecoverable (non-reclaimable) share:
Waste handling and disposal fee:

How to use the result

Use it after a scrap event, a bad run, a slitting failure, an off-spec roll, to quantify the loss and rank it against other waste sources.
It assumes a single blended value per meter and one unrecoverable share, so a roll mixing high- and low-value web, or partially reclaimable trim, needs to be split into separate calculations.

Current U.S. benchmarks

Industrial electricity averages 9.77 cents per kWh across the U.S. (EIA, Jul 2026), up 4.7% from a year earlier. Energy-intensive steps carry this directly into unit cost.
