Composites, Fiberglass & Advanced Materials calculator
Trim Scrap Cost Calculator
Price the trim a cut plan leaves behind from its net weight and the material value it loses. Handling, hauling and disposal are added on top.
What this calculator does
- Cost of cured composite trim from its replacement material value plus the handling, hauling and disposal charge.
Formula used
- Material value lost = trim weight × lost value per pound × counted share ÷ 100
- Total trim scrap cost = material value lost + handling, hauling and disposal
- Scrap cost per pound = total trim scrap cost ÷ trim weight
Inputs explained
- Trim Scrap Weight: Net trim weight from the cut plan or the scale ticket.
- Lost Material Value: Replacement value of the reinforcement and resin in the trim.
- Counted Share: Share of the trim charged to this job, from the cost sheet.
- Handling and Hauling Cost: Handling, hauling and disposal charge for this trim, from the invoice.
How to use the result
- Best suited to pricing trim from a nested ply layout, comparing trim cost across two cut plans, building a scrap reduction case.
- A mixed trim stream needs a blended value per pound or a separate run per material. Rebate or recycling income from the trim is not deducted from the total.
Current U.S. benchmarks
- The producer price index for plastic resins and materials stands at 280.569 (BLS, Aug 2026), up 6.6% from a year earlier. Quotes priced off last quarter's material cost miss this move.
- Steel mill PPI stands at 381.162 (BLS, Aug 2026), up 23.4% from a year earlier. New factory orders are up 8.5% year over year (Census).
Common questions
- What value should I enter for lost trim material? Use the replacement cost of the fiber and resin the trim contains, from the material invoice. Do not use the finished part price, which carries labor and overhead.
- Should handling and disposal be in the per-pound row? Yes, the per-pound row divides the total, so it includes the handling and hauling charge. For material value alone, read the material value lost row.
- How can I cut trim scrap cost? Start with the cut plan: a tighter nest raises the usable area and lowers the trim weight. Then reuse off-cuts for small parts before disposal, which sits last in the waste hierarchy.
- Why is the per-pound row blank when trim weight is zero? A cost per pound with no pounds has no meaning, so the row stays blank and the total shows the handling cost alone. Never read the blank as zero cost.
