By ShipCompare's own modeled comparison tiers, a 1-lb package in a nearby zone runs about $7.85 on USPS, $9.95 on UPS and $10.42 on FedEx ground, and a 20-lb package crossing the country runs about $26.70 to $31.90 across the three, as of July 2, 2026. These are modeled estimates built from ShipCompare's own rate-tier formula, not live carrier quotes; USPS, UPS and FedEx each publish binding rates that change with weight breaks, fuel surcharges and account type. This page names the model's inputs and links the carriers' own rate pages so you can verify.

ShipCompare's Shipping Rate Estimator prices each carrier as a flat per-shipment base plus a per-pound rate and a per-zone step, tuned to sit near published retail ground pricing at the time the tool was built: USPS at $7.00 base + $0.85/lb + $0.90 per zone step above zone 2, UPS at $9.00 base + $0.95/lb + $1.30 per zone step, and FedEx at $9.50 base + $0.92/lb + $1.25 per zone step. In this simplified linear model, USPS's lower base and per-pound rate keep it modeled cheapest across every weight and zone tested, including heavy 50-lb shipments, and FedEx narrows the gap the most on longer zones. The model does not include flat-rate options, residential or fuel surcharges, negotiated commercial rates, or USPS's dimensional-weight rules, all of which can and do change which carrier actually wins for a real shipment; see the USPS vs UPS vs FedEx guide for how those factors play out in practice.
The table above comes directly from ShipCompare's own Shipping Rate Estimator formula, evaluated at eight representative billable-weight and zone combinations. It is a comparison tool, not a live rate feed, and it is reviewed whenever the underlying calculator or carrier rate pages change materially. Last reviewed and republished July 2, 2026.
We link these three pages as the binding primaries. ShipCompare is not affiliated with USPS, UPS, or FedEx, and none of the specific per-shipment dollar prices on this page have been copied from a carrier rate card; they are ShipCompare's own model output, labeled as such.

The model gives USPS the lowest flat base charge and per-pound rate, so it comes out cheapest in this simplified linear formula across every weight and zone tested. Real-world factors such as flat-rate options, surcharges and negotiated rates can change the actual winner for a given shipment.
USPS's dimensional-weight divisor moves from 166 to 139 for Ground Advantage, Priority Mail, Priority Mail Express and Parcel Select effective July 12, 2026, per a USPS Newsroom release dated May 11, 2026 and the accompanying Federal Register filing.
