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.

Empty miles (mi)

Miles driven without freight (empty).

Total miles (mi)

Total miles driven including loaded and empty.

Compute the deadhead ratio as empty miles divided by total fleet or trip miles. 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]

Deadhead (%)

Empty miles as a percent of total miles.

• 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.

• Miles Per Day Average Longhaul Calculator

  Compute average daily mileage for a long-haul run by dividing total miles by days on the route.

• Multi Day Trip Plan Hours Days Calculator

  Plan a long-haul trip by converting miles to drive hours at a planning speed and rounding up to whole driving days under the daily limit.

• TEU FEU Equivalent Conversion

  Convert a mixed fleet of twenty- and forty-foot containers into total twenty-foot equivalent units (TEU) and forty-foot equivalents (FEU), where one FEU equals two TEU.
