Free shipping calculators
Work out what a shipment will be billed on before you ask for a rate. Each calculator shows its math, runs in your browser and needs no sign-up.
Short answer: Carriers rarely bill on scale weight alone. Parcel uses dimensional weight, air uses chargeable weight, ocean LCL uses revenue tons, and pallet freight is priced by weight and trailer space. These calculators show which number applies to your shipment.
