Freight Density Calculator — PCF and NMFC Freight Class Tool

Calculate freight density in pounds per cubic foot (PCF) for LTL freight class determination. Avoid costly carrier reclassifications with accurate class upfront.

Quick answer: Freight class = density-based. Class 50 (50+ PCF) = cheapest. Class 500 (under 1 PCF) = most expensive. A pallet of 500 lbs at 48"×40"×48" = 9.38 PCF = Class 100.

How to Use This Calculator

  1. Measure your shipment — L × W × H in inches, including all packaging and pallet.
  2. Enter total weight — including packaging and pallet.
  3. Verify with NMFC — density drives class for most goods, but some have fixed class regardless — confirm with your carrier.

Worked Example

48"×40"×48" pallet, 500 lbs.

  1. Volume: 48×40×48 ÷ 1,728 = 53.33 ft³
  2. Density: 500 ÷ 53.33 = 9.38 PCF
  3. Class: Class 100
  4. At 36" height: 40 ft³ → 12.5 PCF → Class 85 (cheaper!)

Smart pallet building — compressing load height — reduces freight class and LTL cost significantly.

Frequently Asked Questions

Carrier reclassifies and issues an Additional Freight Charge (AFC) or Weight & Inspection (W&I) fee — typically $50–$300+ plus the rate difference. Accurate class declaration prevents disputes.

Yes — by increasing density: use a smaller box/pallet, remove void space, stack or consolidate. Moving from Class 100 to Class 85 reduces LTL rates 15–25%.
