How do you calculate supplier screening cost?

Multiply the number of lots screened by the cost per lot and your sampling scope to get the variable cost, then add fixed qualification and audit adders. With 18 lots at $640, 80% scope, plus $3,500 in adders, the total is $12,716.

What does the sampling scope percentage mean here?

It is the fraction of each lot (or of all lots) you actually inspect. At 80% you are not doing 100% screening, so the $640 per-lot cost is effectively discounted to about $512 of realized variable cost per lot.

What is a good supplier screening cost per lot for implantables?

There is no universal number — it scales with component criticality. In this example the all-in cost works out to $706.44 per screened lot once adders are spread across the 18 lots, which is reasonable for moderately critical active-implantable components.

Why include qualification and audit adders separately?

Supplier qualification, on-site audits, and PPAP-style first-article work are fixed costs that do not scale with lot count. Keeping the $3,500 separate stops it from distorting your per-lot variable rate.

Can I reduce screening cost by lowering sampling scope?

Sometimes, but for Class III implantable components reduced sampling must be backed by validated supplier capability data and a documented risk assessment — dropping scope without that is an audit finding waiting to happen.

Screening cost vs. cost of a field action — how do they compare?

A $12,716 screening program is trivial next to an implantable field action that can run into millions plus regulatory exposure. Screening is cheap insurance, which is why it survives budget cuts.

Implantable Electronics & Neurodevices calculator

Supplier Screening Cost Calculator

Supplier screening cost is the total spend a neurodevice or active implantable manufacturer carries to verify incoming component lots — ASICs, hermetic feedthroughs, battery cells, lead wire, and titanium cans — before they enter the controlled build. Quality engineers and supplier-quality (SQE) leads use it to size incoming-inspection budgets and to defend make-vs-buy and dual-source decisions to finance. It matters because a single unscreened defect in an implantable can trigger a CAPA, a field action, or worse, so screening is non-negotiable cost rather than optional overhead. This calculator separates the variable per-lot testing burden from the fixed qualification and audit work so you can see which lever actually moves the number.

What this calculator does

Estimate incoming supplier screening cost for critical implantable device components, lots, and qualification adders.
Use it when procurement, supplier quality, or operations needs to cost enhanced inspection for batteries, feedthroughs, electrodes, ceramics, PCBs, or biocompatible materials.
It computes the total cost of screening incoming supplier lots by combining variable per-lot test cost scaled by sampling scope with fixed supplier qualification and audit adders.

Formula used

Variable supplier screening cost = supplier lots or component sets screened × screening cost per lot or set × supplier screening sampling scope
Total supplier screening cost = variable supplier screening cost + supplier qualification and audit adders

Inputs explained

Supplier lots or component sets screened:
Screening cost per lot or set:
Supplier screening sampling scope:
Supplier qualification and audit adders:

How to use the result

Use it when building an incoming-inspection budget, evaluating a new supplier, or justifying a change in sampling intensity for a critical implantable component.
It assumes a single blended cost per lot and a uniform sampling scope across lots; mixed criticality components (e.g. a feedthrough vs. a passive resistor) really need separate runs to avoid averaging away the expensive tests.

Current U.S. benchmarks

The producer price index for copper and brass mill shapes stands at 559.593 (BLS, May 2026), up 76.8% from a year earlier. Quotes priced off last quarter's material cost miss this move. Global copper trades at $13,484 per tonne (IMF via FRED, May 2026).
U.S. manufacturing runs at 75.6% of capacity with new factory orders at $657B per month (Federal Reserve and Census, May 2026).
The U.S. has 11,261 computer and electronic products establishments employing about 815,443 workers (Census County Business Patterns, 2023).
