How do you calculate rework cost for reworked film rolls?

Multiply rolls reworked by the per-roll rate and the recoverable share, then add the changeover charge. For 60 rolls at $45, 80% recoverable, plus a $500 setup, the total is $2,660, or $44.33 per roll.

What does the recoverable share represent?

It's the fraction of rolls you expect to actually save through rework. At 80%, the variable effort is scaled to 60 x $45 x 0.80 = $2,160, reflecting that a fifth of the rolls will end up scrapped despite handling.

Why is per-roll rework cost higher than the per-roll rate?

Because the fixed $500 changeover is spread across the rolls. The $45 rate becomes $44.33 per roll only after the recoverable adjustment lowers variable cost and the setup adds it back — the fixed adder dominates on small lots.

When is it cheaper to scrap film than to rework it?

When the per-roll rework cost approaches or exceeds the roll's material value or resale-as-regrind value. If a defective barrier roll is worth $40 as regrind and rework runs $44 per roll, scrapping wins.

How does lot size change the rework decision?

The $500 changeover is fixed, so per-roll cost falls fast as rolls increase. Reworking 6 rolls carries the same $500 setup as 60, making tiny recovery runs disproportionately expensive.

Should regrind or trim recovery be included here?

No — this tool prices the rework labor and setup. Value recovered from scrapped rolls sold as regrind belongs in the scrap-vs-rework comparison, not in the rework cost itself.

Specialty Films, Membranes & Barrier Materials calculator

Rework Cost Calculator

Rework Cost quantifies what it truly costs to salvage off-spec film, membrane, or laminate rolls instead of scrapping them. On a converting floor, rolls get pulled for gauge bands, telescoping, gel defects, delamination, or wound-in tension faults, and the choice between rewinding and scrapping is a dollars decision. Quality engineers and production supervisors use this to price a rework campaign before committing rewinder time. It captures both the variable per-roll effort and the fixed setup that a changeover on the rewinder or slitter forces.

What this calculator does

Estimate the cost of reworking off-spec film rolls through rewinding, reslitting, relamination or recoating to recover them to spec.
A quality lead decides whether to rework a hold lot of barrier film or write it off as scrap.
It computes the total cost of a rework campaign and the resulting cost per roll, combining a recoverable-adjusted variable cost with a fixed changeover charge.

Formula used

Total rework = rolls reworked x processing rate x recoverable share + changeover charge
Per-roll rework cost = total rework / rolls reworked

Inputs explained

Rolls sent back for rework:
Rework labor and material rate per roll:
Share of rolls actually recoverable:
Rewinder changeover / setup charge:

How to use the result

Use it when deciding whether to rework or scrap a lot of off-spec rolls, and to budget rewinder time for a recovery run.
It assumes a single recoverable share across all rolls; if defect severity varies widely, a blended rate hides rolls that will fail rework and be scrapped anyway.

Current U.S. benchmarks

The producer price index for plastic resins and materials stands at 319.371 (BLS, May 2026), up 19.5% from a year earlier. Quotes priced off last quarter's material cost miss this move.
Global copper trades at $13,484 per tonne (IMF via FRED, May 2026), up 41.5% in a year, and U.S. industrial electricity averages 8.66 cents per kWh. Both feed electrified-hardware unit economics.
