How do you calculate flight hardware scrap cost?

Multiply scrapped units by the fully burdened cost per unit and by the chargeable share, then add the fixed replacement and investigation cost. Here, 7 units at $18,400 fully chargeable gives $128,800, plus $9,500 fixed, for $138,300 total exposure.

Why use fully burdened cost per unit instead of material cost?

By the time flight hardware is scrapped it has absorbed direct labor, machining, special processes, inspection, and traceability overhead. Burdened cost captures all of that; material cost alone can understate true scrap exposure by an order of magnitude.

What is the chargeable scrap cost share for?

It sets how much of the burdened value is your loss versus recoverable, for instance via supplier charge-back, salvage, or rework credit. At 100% the full value is charged; lower it when part of the cost is recovered elsewhere.

What does the fixed replacement and investigation cost cover?

It captures event-level costs that don't scale with unit count: root-cause investigation labor, expedite fees, retooling, and MRB time. In the example it adds $9,500 on top of the $128,800 part value.

How is this different from a scrap rate?

A scrap rate is a percentage of units lost; this calculator turns a specific scrap event into dollars. Use the rate for trend monitoring and this calculator to quantify the financial impact of an actual event.

What is a high scrap cost for flight hardware?

There's no universal threshold because unit values vary widely, but any event that approaches or exceeds a program's monthly margin warrants a formal corrective action. At $138,300, this event is material enough to justify a full investigation, which is exactly why the fixed cost is included.

Aerospace & Defense Manufacturing calculator

Flight Hardware Scrap Cost Calculator

Flight Hardware Scrap Cost quantifies the total dollar exposure when flight-critical parts are scrapped, combining the burdened value of the lost units with the fixed cost of investigation and replacement. Manufacturing engineers, cost-of-quality leads, and program managers in aerospace and defense use it to size scrap events, justify root-cause investigations, and feed cost-of-poor-quality dashboards. Flight hardware scrap is expensive in ways commercial scrap is not: each unit carries fully burdened labor, traceability, and inspection cost, and a single escape can trigger an investigation that costs more than the parts. This calculator captures both pieces so the number you report is the real exposure, not just the part count times a list price.

What this calculator does

Estimate scrap cost for flight hardware from scrapped units, cost per unit, cost capture share, and fixed disposal or replacement cost.
a program or quality manager needs to quantify the cost of scrapped flight hardware in a production lot
It computes total scrap exposure as the chargeable burdened value of scrapped units plus a fixed replacement and investigation cost.

Formula used

Chargeable scrap cost = scrapped units × fully burdened cost per unit × chargeable scrap cost share
Flight hardware scrap cost = chargeable scrap cost + fixed replacement or investigation cost

Inputs explained

Scrapped flight hardware units:
Fully burdened cost per flight unit:
Chargeable scrap cost share:
Fixed replacement and investigation cost:

How to use the result

Use it when closing a scrap or nonconformance event, building a cost-of-quality case, or quantifying the payoff of a corrective action.
The chargeable share is a single percentage; it can't capture downstream schedule cost, customer penalties, or the value of a delayed delivery that often dwarf the part cost itself.

Current U.S. benchmarks

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 11,691 transportation equipment establishments employing about 1,682,910 workers (Census County Business Patterns, 2023).
