How do you calculate the cost of a contamination failure?

Multiply failed parts by cost per part by the scope percentage to get the variable cost, then add the fixed containment cost. Here 85 parts × $240 × 100% = $20,400 variable, plus $7,500 fixed, totals $27,900.

What does the scope percentage do?

It captures what fraction of the per-part cost applies to this event. At 100% the full per-part cost counts; lower it if only part of the population was affected or only partial costs are recoverable.

What is the effective cost per part once fixed costs are included?

Divide total cost by the number of parts. $27,900 over 85 parts is $328.24 per part — well above the $240 raw part cost, showing how fixed containment inflates the real number.

What is a good contamination failure cost target?

There is no universal benchmark; the goal is to drive it toward zero events. Track total cost per event over time and compare against the cost of preventive controls like better filtration or in-line cleanliness checks.

Why include a fixed containment cost?

Because sorting, investigation, expedited freight, and customer communication happen regardless of part count. The $7,500 here is a baseline event cost that one part or a thousand parts would both incur.

Variable cost vs total cost — which do I report?

Report total cost ($27,900) for cost-of-poor-quality and capital justification. Use variable cost ($20,400) when modeling how cost scales with the number of contaminated parts.

Industrial Cleaning, Washing & Parts Cleanliness calculator

Contamination Failure Cost Calculator

Contamination failure cost quantifies the full dollar impact of a parts-cleanliness escape — from scrapped or reworked parts through to the fixed cost of containment and the customer response. Quality managers and operations leaders in industrial cleaning, washing, and surface-cleanliness operations use it to justify investment in better washers, filtration, or inspection. A single contamination event rarely costs only the parts; it triggers sorting, 8D investigations, expedited replacements, and sometimes a line-down at the customer. This calculator separates the variable per-part loss from the fixed event cost so you see the true bill.

What this calculator does

Estimate financial exposure from contamination failures using failed part count, cost per failure, scope, and fixed containment costs.
Use it when particle, residue, oil, or cleaning failures create scrap, warranty, field return, or customer containment risk.
It computes the total dollar cost of a contamination failure by combining a per-part variable loss (scaled by scope) with a fixed containment and customer-response cost.

Formula used

Variable contamination failure cost = contaminated or failed parts × cost per contamination failure × failure cost scope included
Total contamination failure cost = variable contamination failure cost + fixed containment and customer response cost

Inputs explained

Contaminated or failed parts:
Cost per contamination failure:
Failure cost scope included:
Fixed containment and customer response cost:

How to use the result

Use it after a cleanliness escape, when building a cost-of-poor-quality case, or to justify capital for cleaning and filtration upgrades.
It uses a single average cost per part and a fixed lump sum; it will not capture long-tail effects like lost future business or warranty claims that surface months later.

Current U.S. benchmarks

U.S. manufacturing runs at 75.6% of capacity (Federal Reserve, May 2026). New factory orders are up 2.3% year over year (Census).
