A freight class calculator helps shippers determine the correct freight class for their cargo when shipping via less-than-truckload carriers. Freight class is a standardized classification system used by carriers to price shipments based on density, stowability, handling difficulty, and liability. There are 18 freight classes ranging from class 50 for the heaviest and densest items to class 500 for low-density, fragile, or high-value goods. The calculator uses the shipment’s weight and dimensions to compute density in pounds per cubic foot, which is the primary factor in determining the correct freight class.
Using a freight class calculator accurately is critical because misclassification can result in costly reclassification charges from carriers. Businesses that ship products regularly rely on these tools to ensure their freight quotes are binding and accurate. Many online freight calculators also provide instant LTL shipping quotes from multiple carriers. To use the tool, enter shipment dimensions, weight, and commodity type. The calculator displays freight density and recommended class. Understanding freight class also helps businesses negotiate better rates with logistics providers. Online freight class calculators are free and available through major shipping platforms and freight brokers, making them accessible to small businesses and large corporations alike.
