A freight rate (historically and in ship chartering simply freight) is a price at which a certain cargo is delivered from one point to another. The price depends on the form of the cargo, the mode of transport (truck, ship, train, aircraft), the weight of the cargo, and the distance to the delivery destination.

To calculate a freight charge you must first determine which weight break to use based on your shipment weight. Then you divide your total weight by 100 to get your number for 'per hundred pound'. Take this number and multiply it by the applicable CWT from the rate scale.

Air freight rates generally range from $1.50$4.50 per kilogram, while the value of air cargo typically exceeds $4.00 per kilogram.
