Traceability, Serialization & Lot Genealogy calculator
Batch Genealogy Depth Calculator
Batch genealogy depth measures how much it costs to reconstruct the full parent-child lineage of a lot — every raw material sublot, WIP transfer, rework loop, and finished-goods pack that a recall or audit might force you to walk. Quality engineers, traceability leads, and recall coordinators in food, pharma, and aerospace use it to price the effort of a mock recall or a genuine one before it lands. It matters because a shallow one-hop trace is cheap, but a deep multi-generation trace across split and merged lots multiplies the number of links you must capture, verify, and store. This calculator turns link volume, per-link capture cost, and deep-trace intensity into a defensible total.
What this calculator does
- Estimates the cost of capturing and validating multi-level batch genealogy links plus the fixed system overhead to model them.
- A traceability architect sizing the effort to maintain deep parent-child genealogy across multi-stage batch processes for full back-trace capability.
- It computes the total cost of capturing and verifying batch genealogy links plus fixed system overhead, and the resulting cost per link.
Formula used
- Total genealogy cost = links traced x cost per link x deep-trace% + system overhead
- Cost per genealogy link = total genealogy cost / links traced
Inputs explained
- Genealogy links traced:
- Cost per link captured:
- Links requiring deep trace:
- Genealogy system overhead:
How to use the result
- Use it when scoping a mock recall, budgeting a traceability upgrade, or quoting the compliance burden of a new deeply-nested BOM.
- It assumes a uniform cost per link; in reality legacy paper lots or supplier-side gaps can cost far more per link than a clean digital hop.
Common questions
- How do you calculate batch genealogy depth cost? Multiply the number of genealogy links traced by the cost per link, scale by the share requiring a deep trace, then add fixed system overhead. With 6,000 links at $1.80, 45% deep-trace, plus $7,500 overhead, total cost is $12,360.
- What is the cost per genealogy link? Divide total genealogy cost by links traced. In the worked example, $12,360 over 6,000 links is $2.06 per link — the blended figure that includes the fixed overhead spread across every link.
- Why does deep-trace percentage change the cost so much? Only a fraction of links usually need to be walked back through multiple lot generations. Here 45% deep-trace turns 6,000 links into 2,700 effective deep captures, driving the $4,860 variable cost versus the full-population figure.
- What is a good batch genealogy depth cost per unit? There is no universal target, but sub-$1 per link is common for fully digital, single-hop traceability. The $2.06 here reflects meaningful deep-trace intensity and fixed overhead — reasonable for a regulated multi-generation BOM.
- Variable vs fixed genealogy cost — what's the difference? Variable cost scales with link count and deep-trace share ($4,860 here); fixed cost is the $7,500 system overhead you pay regardless of volume. Splitting them shows where automation pays back.
