How do you calculate scrap cost on a PPE line?

Multiply scrapped units by the loaded cost per unit, then by the non-recoverable share, then add fixed disposal and documentation. With 3,000 scrapped units at $0.42 loaded cost, 100% non-recoverable, plus $120 disposal, that is 3,000 × 0.42 × 1.00 + 120 = $1,380 total.

What is 'loaded cost per unit' versus material cost?

Loaded cost includes material plus the labor, machine time, meltblown/BFE testing, and overhead already sunk into the unit before it was scrapped — not just the raw polymer. For a surgical mask that is often 2-4x the bill-of-materials cost.

Why is the non-recoverable share often 100% for infection-control products?

Once medical PPE is contaminated, mislabeled, or fails a barrier test, regulatory and sterility rules usually prohibit rework, so 100% of the loaded cost is lost. In the worked example that is why variable scrap equals $1,260 and none is credited back.

What is a good scrap cost per unit?

There is no universal target — it depends on your product value. What matters is the trend: the example yields $0.46 per scrapped unit, so a mask line running 1% scrap on a 3M-unit month is losing about $13,800. Drive the per-unit figure and the scrap rate down together.

Should disposal and documentation really be in scrap cost?

Yes. Incineration of contaminated PPE, deviation reports, and QA sign-off are cash you spend because the scrap happened. Here the $120 fixed adder is 9% of total scrap cost and is easy to overlook if you count only lost units.

Scrap cost vs rework cost — which should I track?

Track both. Scrap cost captures product you throw away; rework cost captures product you salvage with extra handling. If your non-recoverable share is high, scrap dominates and reducing defects upstream beats investing in a rework cell.

PPE & Infection Control Products calculator

Scrap Cost Calculator

Scrap cost is the money a PPE line loses when masks, gowns, gloves, or face shields fail spec and cannot be sold. On regulated infection-control lines a failed lot often can't be reworked at all — contaminated or out-of-spec product must be documented and destroyed, so the disposal and paperwork burden is real cost, not an afterthought. Quality engineers, cost accountants, and continuous-improvement leads use this figure to size the true impact of BFE failures, meltblown weight defects, or seal-weld rejects and to prioritize corrective action. Tracking scrap cost per unit alongside your first-pass yield turns a vague 'we scrapped a lot this week' into a dollar number you can defend in a Kaizen review.

What this calculator does

Estimates the cost of scrapped PPE and infection-control units including sunk material, labor, and disposal.
A line supervisor uses it to quantify the scrap loss from a gown lot that failed seam-integrity testing.
It computes the total dollar cost of scrapped PPE units — the non-recoverable portion of their loaded cost plus fixed disposal and documentation charges — and the resulting scrap cost per scrapped unit.

Formula used

Total scrap = scrapped units x loaded unit cost x non-recoverable share% + disposal
Per scrapped unit = total scrap / scrapped units

Inputs explained

Scrapped units (masks, gowns, or gloves):
Loaded cost per scrapped unit:
Non-recoverable share (not reworkable or reclaimable):
Disposal, incineration & documentation cost:

How to use the result

Use it when closing out a rejected lot, building a cost-of-poor-quality report, or justifying spend on a defect-reduction project on a mask, gown, or glove line.
It treats the non-recoverable share as a single blended percentage; if some of your scrap is genuinely reclaimable (e.g. regrind on nitrile) you should model that stream separately rather than lumping it in here.

Current U.S. benchmarks

U.S. manufacturing runs at 75.6% of capacity with new factory orders at $657B per month (Federal Reserve and Census, May 2026).
