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 MPG (mpg)

Fuel economy running empty in miles per gallon.

Loaded MPG (mpg)

Fuel economy running loaded in miles per gallon.

Compare loaded and empty fuel economy in MPG and percent. Negative results indicate the measured loaded MPG was higher, not a fuel-economy penalty. 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]

MPG penalty

MPG given up by loading the truck (empty minus loaded).

Loss %

Penalty as a percent of the empty MPG.

• 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.

• Reefer vs Dry Van Rate Delta Lookup

  Compare a refrigerated rate against a dry van benchmark as dollars and percent per mile.

• Shrinkage Percent Inventory Loss Calculator

  Compute inventory shrinkage as the gap between book inventory and the physical count; negative results identify a counted overage rather than a loss.

• Battery UN3480 SoC 30 Percent Checker

  Check lithium-ion cells and batteries shipped standalone under UN 3480 against the IATA requirement of a state of charge not exceeding 30 percent of rated capacity.
