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.

Annual demand

Annual demand in units (D).

Order cost (USD/order)

Fixed cost per order placed in USD (S).

Holding cost/unit/yr (USD/unit/year)

Annual holding cost per unit in USD (H).

Solve the classical Wilson EOQ square root of two DS over H and the implied number of orders per year. 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]

EOQ

Economic order quantity in units.

Orders/year

Orders placed per year at the EOQ.

• 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.

• Travel Time Order Picker Batch

  Split a picker's batch task into travel time (distance over walking speed) and pick time (lines times seconds per line), with documented default speed and pick rate to override with measured values.

• Cartons per Pallet TI-HI Calculator

  Compute pallet TI (whole cartons per layer in the better of two grid orientations) and HI (layers under a usable stack height) with no overhang.

• Fill Rate Line Item Percent Calculator

  Compute the order fill rate as complete line items shipped over line items ordered.
