What this calculator measures

Lean teams see waste categories qualitatively but cannot express each muda type in comparable monetary terms with period context and action priority.

What you get

Structured summary with threshold alerts, hidden drivers and export-ready report output.

What this calculator helps decide

Use this calculator when you need to decide whether current inputs sit inside acceptable exposure bands, which driver to investigate first, and whether to reprice, reschedule or redesign before repeating the work.

What the report includes

• Executive summary with threshold status
• Hidden loss driver breakdown
• Suggested actions and assumption notes
• Export-ready PDF and CSV on paid access

What the preview does not include

The free preview shows sample structure only. Full threshold checks, hidden driver breakdown, suggested actions and export-ready PDF or CSV require paid access.

Assumptions used

• All monetary inputs must use the selected currencyCode for the analysis period.
• productionUnitsInPeriod is the production volume inside the selected analysis period only.
• excessWriteDownCostPerUnit is per excess unit, not a lump-sum write-down total.
• inventoryObsolescenceValue is stock write-down outside excess-production write-down.
• Hourly labor and machine rates are converted to minute costs inside the engineering calculator.
• waitingOpportunityMode controls whether opportunity cost is excluded, manual, or throughput-derived.
• Invalid inputs fail validation explicitly; schema smartDefault values must be present in submitted input values.
