How do you calculate serialized genealogy cost?

Multiply the number of serialized components by the record cost per component, then add fixed setup and labor or system overhead. For 200 components at $3.50 each plus $400 setup and $150 overhead, the total is $1,250.

What is the cost per component for full traceability?

In this example it is $6.25 per component once the $550 of fixed setup and overhead is spread across 200 parts. Per-unit genealogy cost falls as lot size grows because fixed system and setup costs amortize over more serials.

Why is per-component cost higher than the record cost?

The $3.50 record cost per component is only the variable piece. Adding fixed setup and overhead and dividing by 200 parts lifts the effective cost to $6.25 each. On small lots that fixed burden dominates.

Manual genealogy vs eQMS or PLM system?

A system raises fixed setup cost but slashes the per-component record cost and reduces transcription errors. On large serialized lots the system wins; on a one-off lot of a few parts, manual records may be cheaper because the fixed setup is hard to justify.

What drives genealogy cost up on nuclear parts?

Extra NDE result capture, chasing material certs and heat numbers up the supply chain, commercial-grade dedication records, and configuration-management linkage all raise the per-component record cost above a simple as-built log.

How does lot size change the economics?

Because $550 of cost is fixed here, doubling the lot to 400 components would push per-component cost well below $6.25. Traceability is far cheaper per unit on long production runs than on small qualification lots.

Nuclear & Critical Infrastructure Manufacturing calculator

Serialized Component Genealogy Cost Calculator

Serialized component genealogy cost is the price of building and maintaining full birth-to-installation traceability records for each serialized part: material certs, heat numbers, process travelers, NDE results, and as-built configuration tied to a unique serial. Nuclear and critical-infrastructure programs demand this under 10 CFR 50 Appendix B, NQA-1, and customer pedigree requirements so any part can be traced if a defect or counterfeit concern surfaces later. Quality and program managers use this to cost the traceability burden, decide between manual and system-based record-keeping, and price it into the part. The per-component number is what shows up when genealogy is a line item in a quote.

What this calculator does

Estimate the cost to build and maintain serialized genealogy records for nuclear and critical infrastructure components, so traceability and quality teams can quote the work and see cost per component.
Use it when serialized genealogy is being added to a build and you need a defensible total cost and cost per component you can stand behind on a call.
It computes the total cost of serialized genealogy records from a per-component record cost plus fixed setup and labor or system overhead, then divides back to a cost per component.

Formula used

Total genealogy cost = serialized components × record cost per component + fixed setup and system cost + labor and system overhead
Cost per component = total genealogy cost ÷ serialized components

Inputs explained

Serialized components:
Record cost per component:
Fixed setup and system cost:
Labor and system overhead:

How to use the result

Use it when pricing a serialized lot, comparing manual versus eQMS/PLM record-keeping, or budgeting traceability for a pedigree-required contract.
It assumes a flat per-component record cost; parts needing extra NDE traceability, supplier cert chasing, or commercial-grade dedication records can cost far more per unit than the average.
