CargoSum, a freight calculator kit with a 3D loading view
A no-signup toolkit for CBM, chargeable weight, pallet counts, freight class, trailer loading, fuel surcharges, demurrage, and other shipping calculations.
Why it surfaced
CargoSum turns a dense slice of freight paperwork into eleven browser-based calculators, including an interactive 3D view for loading 20ft, 40ft, 40HC, and 45HC containers. It explicitly grounds several calculations in carrier-facing details such as volumetric divisors, container payloads, and the 2025 NMFC density rules—and says users can run it beside a pallet without a signal.
