Freight Density Calculator

Calculating freight density and freight class is easy with our freight density calculator.

Compare Freight Rates

Freight density is the measurement of the shipment’s compactness or pounds per cubic foot (PCF). You will need to know your freight density when using a density-based carrier or when the NMFC for your shipment is Not Otherwise Indicated (NOI). Our freight density calculator will help you determine your cargo’s density and freight class in seconds.

Enter the length, width, height and weight of your cargo. Our freight density calculator will instantly show its freight density and recommended freight class.

How Freight Class and Other Factors Affect Freight Rates

Freight rates are determined by several different factors including package dimensions, weight, distance and freight class, as well as your packages’ Pounds per Cubic Foot (PCF) or density. Your package’s PCF is closely related to the freight class that is applied to your freight shipment. A low PCF will result in a higher class rating. In turn, a higher class rating corresponds to a higher cost to ship your freight.

For example, a shipment that works out to 1.31 pound per cubic foot and weighs 100 pounds (Class 300) will be much more expensive to ship than an item that has the same weight but equates to 9.67 pounds per cubic foot (Class 100). In other words, the more space your freight occupies on a truck or in a container the more costs you will incur for transport. If your commodity or product cannot be classified by a National Motor Freight Classification (NMFC) number, than apply a general class rate or NOI (Not Otherwise Indicated) class to determine your cost to ship. NOI shipping terms are typically quoted and processed manually through select freight carriers. For this reason, shippers are encouraged to make sure their weights and dimensions are accurate in order to avoid billing adjustments based on PCF and class changes. By far the most common reason for a re-bill or billing adjustment, it is also the most avoidable. Never guess or estimate dimensions and weights when shipping freight.
