Our shipping cost estimator uses carrier pricing formulas to calculate estimated shipping costs based on weight, dimensions, distance, and service type. The calculation applies standard carrier methodologies including dimensional weight pricing to help you estimate costs and optimize packaging for the most cost-effective shipping.
Carriers charge for the space your package occupies (dimensional weight) or the actual weight, whichever is greater. This encourages efficient packaging and prevents shippers from sending large, lightweight packages that waste cargo space.
Major carriers (UPS, FedEx) use 8 shipping zones based on distance from origin to destination. Understanding zones helps you estimate costs and make strategic decisions about fulfillment center locations.
