About this calculator
LTL freight class is driven mostly by density: pounds per cubic foot. Higher density means lower class and a cheaper rate. Compute density from your pallet dimensions and see the standard class band.
Worked example
Using the values the calculator loads with:
Inputs
- Pallet length: 48 in
- Pallet width: 40 in
- Pallet height: 48 in
- Total weight: 750 lb
- Number of pallets: 1
Results
- Estimated freight class: 78
- Density (lb per cubic foot): 14.06
- Cubic feet per pallet: 53.33
- Total cubic feet: 53.33
- Total shipment weight (lb): 750
What each field means
Inputs
- Pallet length (in)
- The pallet length used in the calculation, measured in in. Starts at 48 in so you have a working example on load.
- Pallet width (in)
- The pallet width used in the calculation, measured in in. Starts at 40 in so you have a working example on load.
- Pallet height (in)
- The pallet height used in the calculation, measured in in. Starts at 48 in so you have a working example on load.
- Total weight (lb)
- The total weight used in the calculation, measured in lb. Starts at 750 lb so you have a working example on load.
- Number of pallets
- The number of pallets used in the calculation. Starts at 1 so you have a working example on load.

FAQ
Is class always based on density?
No. NMFC also weighs stowability, handling, and liability, and many commodities carry a fixed class regardless of density. Density is the right starting point for general freight.
Why does a reclass cost so much?
Carriers inspect and rebill when the actual density differs from the bill of lading, and reclass invoices frequently exceed the original rate plus an inspection fee.
Accuracy and limitations
- Estimates assume standard, average conditions — local rules, pricing, and materials vary.
- Results are rounded for readability; add a buffer before ordering, booking, or committing.
- Double-check anything with a real cost attached against a local quote.
