Freight Class Calculator

Estimate NMFC freight class from shipment density.

Density (lb/ft3) 6.667

Freight class 125

Formula: Density determines the NMFC class

Step-by-step with your numbers:

1. Values used:

2. Weight = 200

3. Volume = 30 ft3

5. Density = Weight / Volume = 200 / 30 = 6.667lb/ft3

6. Freight class = 125

Did we solve your problem today?

Freight class rates shipments mainly by density, affecting shipping cost.

The math behind it

Density = weight / volume. Denser freight gets a lower class number and usually a lower rate.

200 lb in 30 ft3 is 6.67 lb/ft3, around class 125.

Is density the only factor?

Mostly, but stowability, handling and liability also matter for some commodities.
