How do you calculate equipment rework cost?

Multiply rework labor hours by the loaded labor rate, then by the share of the build actually affected, and add fixed replacement material plus retest cost. With 140 hours at $95/hr on 100% of the build plus $8,500 fixed, that is 140 x 95 x 1.00 = $13,300 variable plus $8,500 = $21,800 total.

What should be included in the loaded rework labor rate?

Use a fully loaded rate covering wages, benefits, payroll burden, supervision, and an overhead allocation for the bay and tooling, not the bare hourly wage. That is why the blended figure in this example resolves to about $155.71/hr once fixed costs are spread across hours.

What counts as fixed replacement material and retest cost?

It is the cost that does not scale with labor hours: scrapped parts that must be re-bought, consumables, plus re-running the functional acceptance or factory acceptance test. In the example that fixed block is $8,500 on top of $13,300 of variable rework.

Why use an affected build share instead of just total hours?

When only part of a multi-station assembly is touched, the affected build share scales the labor so you are not over-counting. At 100% the full crew time applies; at 50% you would halve the $13,300 variable cost to $6,650.

Is rework cheaper than scrapping the equipment?

Often yes, but not always. Compare this total against the standard cost to build new. If rework lands at $21,800 against a $35,000 build cost it pays, but heavy retest or warranty risk can flip the decision toward scrap-and-rebuild.

How is rework cost different from cost of poor quality?

Rework cost is one line item inside cost of poor quality. COPQ also rolls in scrap, warranty, returns, and lost throughput; this calculator isolates the rework slice so you can target it in corrective action.

Industrial Equipment, Machinery & Capital Goods calculator

Equipment Rework Cost Calculator

Equipment rework cost is the all-in dollar impact of correcting a defective or out-of-spec build on a piece of capital machinery before it can ship or be accepted. Project engineers, quality managers, and program controllers on heavy equipment, packaging line, and machine-tool builds use it to quantify the real cost of a teardown-and-redo rather than waving it off as a few labor hours. It matters because rework on a complex assembly almost always carries hidden replacement material and full retest cost that dwarfs the wrench time. Capturing it cleanly lets you charge the cost to the right account, decide whether to scrap versus repair, and feed corrective-action ROI.

What this calculator does

Estimate equipment rework cost from rework labor hours, loaded labor cost, affected build share, and fixed replacement material or retest cost.
Use it when evaluating nonconforming assemblies, wiring errors, fit-up issues, failed tests, or customer punch list rework.
It computes total equipment rework cost as rework labor hours times the loaded labor rate times the affected build share, plus a fixed replacement material and retest amount.

Formula used

Variable equipment rework cost = rework labor hours × loaded rework labor cost × affected build share
Total equipment rework cost = variable equipment rework cost + fixed replacement material and retest cost

Inputs explained

Rework labor hours:
Loaded rework labor cost:
Affected build share:
Fixed replacement material and retest cost:

How to use the result

Use it when a build fails inspection, FAT, or commissioning and you need a defensible cost before authorizing the rework order.
It assumes a single blended labor rate and a flat fixed cost; staged rework across multiple trades or production stoppage downtime is not modeled and should be added separately.

Current U.S. benchmarks

As of Jun 2026, average hourly earnings in U.S. manufacturing are $30.27 (BLS), up 4.4% from a year earlier. Burdened shop rates typically run 1.3 to 1.8 times earnings once benefits and overhead are loaded.
The U.S. prime lending rate is 6.75% (Federal Reserve via FRED, 2026-07-02). Payback and financing math should start from today's rate, not a remembered one.
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).
The U.S. has 21,668 machinery manufacturing establishments employing about 1,086,146 workers (Census County Business Patterns, 2023).
