How do you calculate the cost of rework?

Multiply the number of units needing rework by the per-unit labor and parts cost, scale by the affected scope, then add containment and retest costs. For 26 units at $145 each across 100% scope plus $900 containment, total rework cost is $4,670.

What is rework cost per unit?

It is the total rework cost spread across the affected units. In the example, $4,670 across 26 units works out to about $179.62 per unit, which is higher than the $145 fix cost because containment is shared across the batch.

What counts as containment and customer-protection cost?

Anything spent to stop the defect from reaching or harming the customer: sorting, 100% retest, expedited re-inspection, field-service trips, and temporary screening. In the example these add $900 on top of the $3,770 variable rework.

Why include affected scope as a percentage?

Sometimes only part of a batch or project is at risk. Scope lets you scale the variable cost: at 100% all 26 units are reworked, but at 50% you would price half the variable cost while still carrying full containment.

Rework cost vs scrap cost: which is cheaper?

Rework is usually cheaper than scrapping a fabricated stainless unit, but not always. If per-unit rework approaches the build cost, scrapping and remaking can be the better call, so compare both before deciding.

Commercial Kitchen Equipment calculator

Rework Cost Calculator

Rework Cost puts a hard dollar figure on fixing defective kitchen equipment before it ships, so quality and operations leaders stop treating rework as a hidden cost of doing business. Plant managers and quality engineers handling failed leak tests, bad welds, or NSF-finish issues on ranges, hoods, and refrigeration use it to size the financial damage of a defect batch. It matters because rework is not just relabor: containment, retest, and customer-protection costs (expedited inspection, sorting, even site visits) often dwarf the per-unit fix. Quantifying the total builds the business case for fixing the root cause instead of repeatedly absorbing the cost.

What this calculator does

Estimate rework cost for commercial kitchen equipment caused by finish defects, leaks, wiring issues, failed tests, or damaged components.
costing rework on commercial kitchen equipment builds
It computes total rework cost by multiplying units, per-unit rework cost, and affected scope, then adding containment, retest, and customer-protection costs.

Formula used

Variable rework cost = commercial kitchen units needing rework × rework labor and parts cost per unit × affected production or project scope
Total rework cost = variable rework cost + containment, retest, and customer-protection costs

Inputs explained

Commercial kitchen units needing rework:
Rework labor and parts cost per unit:
Affected production or project scope:
Containment, retest, and customer-protection costs:

How to use the result

Use it after a defect escape or batch failure to size the loss and justify corrective action or a supplier charge-back.
It captures direct rework and containment dollars but not lost throughput, delayed-shipment penalties, or reputational damage, so the true cost of a defect is usually higher than the figure shown.

Current U.S. benchmarks

Industrial natural gas averages $4.9 per Mcf (EIA, Apr 2026), down 7.7% from a year earlier, with industrial electricity at 8.66 cents per kWh. Process heating and refrigeration budgets track both.
Steel mill PPI stands at 348.53 (BLS, May 2026), up 6.7% from a year earlier. New factory orders are up 2.3% year over year (Census).
