Shipping rates are the cost of a shipment based on several factors, like a package’s weight, dimensions, the sender address, the destination address, and the shipping service level. When you are creating a shipping label within Shippo, you will see a list of discounted shipping rates that you can choose from across various service levels (e.g. UPS Ground, FedEx Ground Economy, USPS Ground Advantage). You can then compare the results to determine the option that works best for your shipment.
USPS shipping costs vary by service level. For USPS Priority Mail, for example, the cost is based on weight and distance traveled. There are a few exceptions.
First, USPS Priority Mail Cubic is one of the cheapest shipping options for packages smaller than a shoebox because the rates are determined by package size instead of weight.
For packages larger than 1 cubic foot in volume, the USPS also implements Dimensional Weight pricing, which takes size into account when determining the price.
And, with the USPS Priority Mail Flat Rate service, size and weight don’t matter as long as your item fits within the corresponding package.
USPS shipping costs are calculated based on weight and distance traveled.
