FREIGHT CALCULATORS · UNITED STATES
Find your freight class in 10 seconds.
Uses the 13-tier NMFC density scale that took effect in July 2025. Many older calculators still use the old one. 13 free tools for LTL, ocean, air and trucking, every result showing its working.
UNITS
Measure the outside of the handling unit including the pallet and any overhang, and weigh it with all packaging.
HOW WE GOT THERE1. 48 × 40 × 50 in = 55.56 ft³ per unit2. 600.00 lb ÷ 55.56 ft³ = 10.80 lb/ft³3. 10.80 lb/ft³ falls in the 10–12 band → class 92.5
