What belongs in the cost per repair?

Labor, material and the tooling consumed on one typical repair, taken from the repair quote or a time study. If repairs range from a small blister to a full section replacement, split them into groups and cost each group at its own rate.

How does the counted share change the total?

It scales only the variable line: repairs times cost per repair. The fixed setup cost is added once whether the share is 100 percent or 40 percent, so a smaller counted share does not remove the setup burden.

Why is cost per repair blank when repairs are zero?

There is no repair to divide the setup cost across, so the page leaves the row blank instead of showing an infinity or a fake zero. The total still shows the fixed setup that stands regardless.

Does the fixed setup cost repeat every repair batch?

Count it once for the job or lot the page describes. If the same setup serves several batches, enter only the share of it that this job should carry, or the total will overstate the repair cost.

Composite Repair Cost Calculator

Cost a batch of composite repairs from the repair count, the cost per repair and the share you count, then add the fixed setup. The per-repair row shows what each repair carries after the fixed cost spreads over the count.

What this calculator does

Repair cost from the number of repairs, the cost per repair, a counted share and fixed setup.

Formula used

Variable repair cost = repairs needed × cost per repair × counted share ÷ 100
Total repair cost = variable repair cost + fixed repair setup cost
Cost per repair = total repair cost ÷ repairs needed, blank when repairs needed is zero

Inputs explained

Repairs Needed: Composite defects sent to repair, from the nonconformance log.
Cost per Repair: Labor and material for one typical repair, quoted or time studied.
Counted Share: Share of the repair scope charged to this job, from the quote.
Fixed Repair Setup Cost: Setup, fixtures and inspection charged once, from the repair quote.

How to use the result

Best suited to costing a repair batch from the nonconformance log, quoting a repair touch-up on delivered parts.
A mixed repair scope with very different repair sizes needs a weighted cost per repair. Travel, downtime and reinspection outside the repair quote are not included.

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).
