How do you calculate total rework cost?

Multiply reworked units by per-unit cost and the allocation share to get variable cost, then add the fixed containment cost. Here 96 × $31 × 100% = $2,976 variable, plus $2,100 fixed = $5,076 total.

What is the cost per reworked unit?

Divide total cost by units reworked. With $5,076 across 96 units, the fully loaded cost is $52.88 per unit — well above the $31 variable rate because the fixed debug cost spreads across the batch.

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

The fixed containment and debug cost ($2,100) is shared across the reworked units. At 96 units it adds about $22 each, pushing the $31 variable rate up to $52.88 fully loaded.

What does the allocation percentage do?

It assigns a share of the rework cost to this specific build when the same failure or fixture touches multiple programs. At 100% the entire variable cost lands on this build; at 50% only half would.

When should I scrap instead of rework?

Scrap when the fully loaded rework cost approaches the unit's build cost or margin contribution. If repairing a controller costs $52.88 and its gross margin is $40, scrapping and rebuilding may be cheaper.

How do I reduce rework cost?

Attack the fixed debug cost with faster root-cause and the variable cost with better first-pass yield. Cutting reworked units from 96 to 48 here would roughly halve the variable portion to $1,488.

Gaming & Entertainment Hardware calculator

Rework Cost Calculator

Rework Cost is the total money a build absorbs to fix units that failed test, combining a per-unit variable cost with the fixed cost of containment and root-cause debug. For gaming hardware — controllers, mainboards, VR optics modules — rework is where thin quote margins quietly disappear. Quality engineers and production cost analysts use this to put a dollar figure on a yield excursion and to decide whether to repair, scrap, or redesign. It separates the scalable per-unit repair spend from the one-time engineering cost of containing the failure.

What this calculator does

Estimate rework cost for gaming and entertainment hardware defects found during assembly, test, calibration, burn-in, cosmetic inspection, or final QA.
Use it when solder touch-up, connector replacement, joystick centering, firmware reflash, display reseat, speaker repair, enclosure repair, LED replacement, or retest labor affects unit cost.
It sums variable rework (units × per-unit cost × allocation) with a fixed containment and debug charge to give total rework cost and cost per reworked unit.

Formula used

Variable rework cost = units requiring rework × rework cost per unit × rework cost allocated to this build
Total rework cost = variable cost + fixed containment and debug cost

Inputs explained

Hardware units sent back for rework:
Rework labor and parts cost per unit:
Share of rework cost charged to this build:
Fixed containment and debug cost:

How to use the result

Use it after a test-failure event or yield excursion to quantify the financial hit and support a repair-versus-scrap decision.
It does not capture downstream costs of escaped defects — field returns, RMA freight, or brand damage — which can dwarf the shop-floor rework bill.

Current U.S. benchmarks

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.
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).
