How do you calculate rework cost for PPE?

Multiply units reworked by the handling rate, then by the recoverable share, then add fixed cell setup and re-QC. With 2,500 units at $0.55 handling, 88% recoverable, plus $260 setup, that is 2,500 × 0.55 × 0.88 + 260 = $1,470 total.

What does 'recoverable share' mean here?

It's the fraction of reworked units you expect to salvage and ship after the second pass. At 88% you're accepting that roughly 12% will still fail and drop out — which is why variable rework cost is $1,210 rather than the full handling spend.

What is a good rework cost per unit?

Lower than your scrap cost per unit, or rework isn't worth it. The example lands at $0.588 per reworked unit; compare that against what you'd lose scrapping the same units to decide which path protects margin.

Rework cost vs scrap cost — when do I rework?

Rework when the salvage cost per unit is meaningfully below the loaded cost you'd lose to scrap and when regulatory rules permit re-inspection. If rework barely beats scrap, the extra handling risk usually isn't worth it on medical PPE.

Why include setup and re-QC as a separate cost?

Standing up a rework cell and running a second QC gate is a fixed cost you pay regardless of batch size. Here the $260 adder is 18% of total rework cost, so small rework batches carry a heavy fixed burden per unit.

Does rework cost include the original production cost?

No — the units were already made. Rework cost is only the extra spend to salvage them. The original loaded cost is sunk; this calculator captures the incremental handling, setup, and re-verification you add on top.

PPE & Infection Control Products calculator

Rework Cost Calculator

Rework cost is what you spend to salvage PPE units that failed inspection but can be brought back to spec — re-trimming a gown seam, re-attaching an ear loop, re-inspecting and relabeling a carton after a print error. Unlike scrap, rework keeps the product, but it consumes a dedicated cell, extra labor, and a second QC pass, and on infection-control products every reworked unit must be re-verified before it can ship. Process engineers and cost accountants use this number to decide whether salvaging a defect stream is cheaper than scrapping it and to track the hidden labor drain of chronic rework. The per-unit figure is what tells you if your rework cell is quietly eating your margin.

What this calculator does

Estimates the cost to rework PPE and infection-control products such as masks, gowns, and shields.
A quality lead uses it to weigh reworking versus scrapping a lot of masks with off-center ear loops.
It computes the total dollar cost to rework a batch of PPE units — the recoverable portion of handling cost plus fixed cell setup and re-QC — and the resulting rework cost per unit.

Formula used

Total rework = units reworked x handling rate x recoverable share% + setup & re-QC
Per unit = total rework / units reworked

Inputs explained

PPE units routed to rework:
Rework handling & relabel rate:
Recoverable share (units salvaged after rework):
Rework cell setup & re-QC cost:

How to use the result

Use it when a defect stream is salvageable and you're deciding between rework and scrap, or when building the rework line of your cost-of-poor-quality report.
It assumes reworked units actually pass the second inspection; if your rework yield is below the recoverable share you enter, real cost per shippable unit will be higher than the figure shown.
