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:

Large boxes may cost more even if they are lightweight.
3. Origin ZIP Code

4. Destination ZIP Code
The delivery address ZIP Code determines shipping distance and zone.

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