Plan freight with numbers you can actually use.
Free calculators for parcel shipping, LTL density, freight class, pallets, air cargo and container loading — with transparent formulas and source-linked assumptions.
Most-used freight tools
Focused calculators for the shipment measurements that repeatedly show up in parcel, LTL, air and ocean workflows.
DIM Weight
Calculate dimensional and billable weight for FedEx, UPS, USPS and DHL-style parcel rules with imperial or metric inputs.
Freight Class
Estimate density-based NMFC freight class using the current 13-sub density structure and your handling-unit dimensions and weight.
Pallet
Estimate cartons per layer, layers per pallet, pallet capacity, gross weight and pallets required with common U.S. and European pallet presets.
CBM
Calculate cubic meters, cubic feet, shipment volume and optional shipment density for cartons, crates and freight pieces.
Container Load
Estimate identical cartons per 20ft, 40ft and 40ft high-cube container with orientation, payload and volume-utilization checks.
Chargeable Weight
Compare actual gross weight with air-freight volumetric weight using the common 6,000 cm³/kg rule or a custom divisor.
Calculators by freight category
Each category is designed as a coherent workflow rather than a random toolbox.
Parcel Shipping
Plan parcel size, dimensional weight and carrier size checks with current, source-linked calculators.
Freight & LTL
Calculate freight class, LTL density, loading meters and shipment cube for road and less-than-truckload freight.
Pallets & Packaging
Estimate cartons per pallet, pallet capacity, loaded height, weight and space utilization.
Air Freight
Compare gross and volumetric weight, calculate air-cargo cube and understand chargeable-weight rules.
Containers & Ocean
Calculate CBM and estimate uniform-carton capacity for 20ft, 40ft and 40ft high-cube containers.
