How USPS Ground Shipping Cost is Calculated

USPS shipping rates depend on several important factors.

Main Inputs Required

1. Package Weight

Heavier packages usually cost more to ship.

Example:

2 lbs package = lower cost

Height

Large boxes may cost more even if they are lightweight.

4. Destination ZIP Code

The delivery address ZIP Code determines shipping distance and zone.

5. Shipping Zone

USPS uses shipping zones based on distance between origin and destination.
