What is FedEx One Rate?
FedEx One Rate® shipping is a flat-rate shipping option that lets you ship packages for a fixed price based on package size, destination zone, and service level, rather than weight alone. This makes it one of the easiest ways to calculate FedEx shipping rates quickly and predict shipping costs.
Instead of weighing packages to determine pricing, FedEx One Rate uses standardized packaging sizes such as envelopes, Paks, and boxes. If your shipment fits within the allowed FedEx One Rate sizes and dimensions, you qualify for flat-rate pricing.
Our FedEx One Rate calculator helps you instantly determine which package category your shipment falls into and displays the applicable FedEx One Rate shipping rates for available services.

Pricing is based on package type, not actual package weight
You can ship heavier items without increasing cost (up to 50 lbs)
