How to use this table

Use this to understand why a carrier tends to win for a given shipment profile, then confirm the actual cost with a live quote. As a rule of thumb from our full carrier comparison guide: light, small, long-distance packages tend to favor USPS; heavier packages or short-zone shipments increasingly favor UPS or FedEx, especially at negotiated commercial rates.

Why we don't publish live dollar rates

Published retail rates change with each carrier's annual general rate increase and periodic surcharge adjustments — UPS and FedEx both raised rates by an average of 5.9% for the 2026 cycle, and USPS raised Ground Advantage roughly 7–8%, per our carrier surcharge trends research. A dollar figure published today would likely be wrong within months. Structural differences — divisors, thresholds, zone sensitivity — change far less often, which is why this table focuses on those instead.
