Use this logistics calculation for a transparent shipment, inventory, warehouse, customs, packaging, carrier, or service-level estimate when the governing units and business rules are explicit.

Cumulative value share (%)

Cumulative percent of total annual usage value after items have been ranked from highest to lowest annual usage value.

Classify an item by cumulative annual-usage-value share using fixed policy thresholds: A from 0% through 80%, B above 80% through 95%, and C above 95% through 100%. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

ABC class

ABC class assigned by the fixed 80% and 95% boundaries.

• Carrier tariffs, customs rules, dangerous-goods requirements, hours-of-service rules, surcharges, port terms, dimensional divisors, and service definitions vary by jurisdiction, contract, date, mode, and commodity. A calculation is not a booking, classification, or compliance determination.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Verify current carrier and authority documents, retain shipment dimensions and timestamps, test boundary cases, and reconcile estimates against invoices and operational scans.

• Slotting Velocity ABC Classifier

  Pareto-slot an item by its cumulative share of pick throughput: A up to the first boundary (default 80%), B to the second (default 95%), C beyond; boundaries are inputs.
