How do you calculate appliance rework cost?

Multiply units requiring rework by cost per reworked unit by the scope percentage to get variable cost, then add fixed support cost. With 210 units at $64 and 100% scope you get $13,440 variable, plus $3,500 fixed, for $16,940 total.

Why is the cost per reworked unit higher than my labor-and-parts input?

Because fixed support cost is spread across the reworked units. Here the input is $64 but the effective cost per reworked unit is about $80.67 once the $3,500 rework cell cost is amortized over 210 units.

When should I scrap instead of rework?

Compare the effective per-unit rework cost against the unit's scrap cost net of recovered parts. If repairing costs more than the $80.67 per-unit figure here would on your line, scrapping and rebuilding from good stock is often cheaper.

What does the rework cost scope percentage do?

It scales the variable cost so you can attribute only part of the rework load to this analysis. Keep it at 100% for the full batch, or lower it to isolate one defect family or one product line.

What is a good rework rate or cost for appliance lines?

There is no universal dollar benchmark, but rework cost should fall as your defect rate falls. Track it as a percent of total production cost and trend it down; a rising rework total alongside a flat defect rate signals harder repairs.

How do I use this to justify a quality project?

The total here, $16,940 for one batch, is the annualized prize. Multiply by the number of similar periods, then compare against the cost of the root-cause fix; if the fix pays back inside a year on avoided rework, it is an easy approval.

Appliance Rework Cost Calculator

Rework is the hidden tax on a defect rate: every unit pulled off the line for repair consumes labor, parts and floor space that never shows up in standard cost. This calculator totals your appliance rework cost by combining the variable per-unit repair cost across all reworked units with the fixed cost of running a rework cell or debug station. Quality and operations managers use it to put a dollar figure on cost-of-quality, to justify root-cause projects, and to decide when scrapping beats repairing. Because rework competes with production for the same people and time, knowing its true cost is what turns a quality problem into a funded improvement.

What this calculator does

Estimate rework cost for appliances or HVAC units from reworked units, labor and parts cost per unit, rework scope, and fixed support cost.
a production or quality manager needs to estimate the cost impact of appliance rework
It computes total appliance rework cost as the variable per-unit repair cost across reworked units plus the fixed cost of rework support and debug.

Formula used

Variable rework cost = units requiring rework × labor and parts cost per reworked unit × rework cost scope included
Total appliance rework cost = variable rework cost + fixed rework support or debug cost

Inputs explained

Appliance units requiring rework:
Labor and parts cost per reworked unit:
Share of rework cost captured:
Fixed rework cell, support or debug cost:

How to use the result

Use it to quantify cost-of-quality for a period, to build the business case for a root-cause fix, or to compare repair cost against scrap cost.
It uses one average per-unit rework cost, so a quick reflash and a full teardown-and-rebuild are blended, which can understate the cost of your hardest repairs.

Current U.S. benchmarks

Industrial electricity averages 8.66 cents per kWh across the U.S. (EIA, Apr 2026), up 5.5% from a year earlier. Energy-intensive steps carry this directly into unit cost.
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).
