Freight density calculator
Calculate pounds per cubic foot (PCF) from pallet dimensions to verify NMFC classification and dispute carrier W&I penalties.

Classification & Density Result
Class 85At 12.19 PCF, the NMFTA density guideline maps to Class 85 (12–15 PCF tier). Actual NMFC classification can also depend on the applicable item plus handling, stowability, and liability characteristics.

How to Calculate Freight Density (PCF) and NMFC Class?
To calculate freight density in pounds per cubic foot (PCF), multiply pallet length, width, and height in inches, divide by 1,728 to find total cubic feet, and divide total weight by cubic feet. Formula: Total Weight in LBS ÷ [(Length × Width × Height) ÷ 1,728] = Density (PCF). For freight that uses the 13-sub full-density structure, the density can be mapped to a class band; the applicable NMFC item and any handling, stowability, liability, packaging, or tariff rules still control the shipment classification.
Step-by-Step Pallet Density Calculation Example
Assume a standard GMA pallet measuring 48" L × 40" W × 48" H weighing 650 LBS:
- Calculate total cubic inches:
48 × 40 × 48 = 92,160 Cu. In. - Convert to cubic feet (divide by 1,728):
92,160 ÷ 1,728 = 53.33 Cu. Ft. - Divide total weight by cubic volume:
650 LBS ÷ 53.33 Cu. Ft. = 12.19 PCF - Compare the published 13-sub density structure:
12.19 PCF falls in the 12–15 PCF bracket → Class 85
Use the Density Result as a Review Signal
The calculator uses the published 13-sub full-density structure as a screening reference. It does not reproduce or replace the NMFC. Confirm the current NMFC item and class in ClassIT+ and check the governing carrier tariff or contract before changing a classification or disputing a charge.
