Shipping & Freight Cost Calculators
Calculate dimensional weight, courier zone charges, and volumetric freight penalties before dispatching orders. Built for D2C brands and marketplace fulfillment teams.
Courier Volumetric Weight Calculator
Calculate package volumetric weight in kilograms to avoid courier dead-weight penalty charges.
Dimensional Weight (DIM) Calculator
Compare physical scale weight against cubic dimensional weight for carton shipping.
Freight Density & Class Calculator
Calculate pallet density in PCF to find the correct NMFC freight class.
Carrier Dimensional Weight (DIM) & Volumetric Standards
Couriers bill shipments based on either gross scale weight or dimensional (volumetric) weight—whichever is greater. Our shipping calculators apply standard domestic (139 / 5000) and international (166 / 6000) divisors to prevent unexpected carrier surcharge adjustments.
Standard IATA Volumetric Formula
Volumetric Weight (kg) = (Length × Width × Height in cm) / 5000 for standard domestic express, or / 6000 for air cargo.
Imperial DIM Weight Formula
DIM Weight (lbs) = (Length × Width × Height in inches) / 139 for FedEx/UPS domestic, or / 166 for retail rates.
Freight Density & NMFC Classification
Freight density (lbs per cubic foot) determines Less-Than-Truckload (LTL) shipping class between Class 50 and Class 500.
Palletization Optimization
Calculate cubic space utilization on standard 48x40-inch GMA wooden pallets to prevent over-hang fines.
