Freight Class Calculator

Determine freight class and calculate LTL shipping rates based on density and commodity type

About this calculator

The Freight Class Calculator helps determine the proper freight classification for your shipments and estimates LTL (Less Than Truckload) shipping rates. This tool uses commodity density, dimensions, weight, and product type to calculate the correct NMFC (National Motor Freight Classification) class, which directly impacts shipping costs. Accurate freight classification ensures proper pricing, prevents billing adjustments, and helps logistics managers budget effectively for transportation expenses.

How to use

Enter your shipment's weight, dimensions (length, width, height), and select the commodity type from the dropdown menu. The calculator will compute the density and determine the appropriate freight class (50-500). Review the estimated LTL shipping rates based on your classification to plan your shipping budget accordingly.

Frequently asked questions

What is freight class and why does it matter?

Freight class is a standardized classification system (Classes 50-500) that determines LTL shipping rates based on density, handling, liability, and stowability of commodities.

How is freight class calculated?

Freight class is primarily determined by density (weight per cubic foot), along with factors like handling difficulty, liability risk, and how well items stack together.

What happens if I use the wrong freight class?

Using incorrect freight class can result in billing adjustments, additional fees, shipping delays, and potential reclassification charges from the carrier after delivery.
