About CargoSum

CargoSum started as an in-house calculator built by people working in ocean freight. Most days meant CBM sheets, planning how to load the container and working out chargeable weight, often against a cutoff and in a spreadsheet that someone had broken along the way.

That first calculator turned a roughly five-minute manual job into an instant answer, and the team kept using it far longer than anyone expected. Since then, the people behind CargoSum have moved on to building software for freight and container logistics. The goal is the same as it was then: numbers you can check by hand, in software an operations team can rely on when a deadline is close.

CargoSum is free to use and needs no account. It is built for freight forwarders, shippers and importers, and covers ten freight calculators: CBM, chargeable weight, freight class, freight density, pallet loading, 3D container loading, linear feet, trailer loading, fuel surcharge and demurrage, plus reference pages on container specifications and Incoterms. Every number is calculated in your browser. Each tool lists its primary sources and the date they were last reviewed. Those sources include published standards (IATA, NMFTA's National Motor Freight Classification, ISO 668, pallet standards and the ICC), less-than-truckload (LTL) carriers' rules tariffs, and US government sources such as EIA diesel prices and the FMC. Treat the results as planning figures. What you are billed, and how the cargo actually loads, depend on your shipping line, airline or LTL carrier, their tariffs and the physical cargo, so check the numbers against theirs before you rely on them.

CargoSum is run by Rivly, an independent software studio registered in South Korea.
