About Freight Calculator Hub

Freight Calculator Hub is a focused set of free tools for everyone who ships freight — from one-pallet sellers to brokers quoting all day. We build one clean calculator per job: freight class, CBM, dimensional and chargeable weight, pallet and container loading.

The math should be accurate, instant, and visible. Every result shows how it was calculated, nothing hides behind a sign-up or pop-up, and each tool is built for the phone first — because that’s where most shipment checks actually happen.

The numbers come from published freight standards, not guesswork: the NMFC density scale for freight class, standard carrier dimensional divisors for chargeable weight, and real container and pallet dimensions. See exactly how each calculator works and where the data comes from.

Where our numbers come from

We use primary sources and name them on the page that uses them:

• the 13-tier NMFC density scale from Docket 2025-1, in force since July 19, 2025;
• the rules tariffs of XPO, Estes, Saia, Old Dominion, R+L Carriers, TForce Freight and FedEx Freight, for cubic minimums, height rules and charges;
• USPS, UPS and FedEx published rules for dimensional weight;
• ISO 6780 and the EPAL, CHEP and PECO specifications for pallets, and published container specs;
• federal regulations, such as the hazmat rules in 49 CFR, read on eCFR;
• manufacturers' spec sheets for product weights, sizes and pallet counts.

When a source changes, such as a new carrier tariff, we update the page and its date. We do not publish freight rates for a lane or a price per pallet, because those depend on your shipment and your contract, and a made-up number would mislead you. Where a page uses an example figure of our own, it says so.
