How to calculate USPS shipping cost by weight?
USPS uses weight tiers (e.g., up to 4 oz, 8 oz, 1 lb, etc.). Once your item exceeds 1 lb, zone-based pricing applies. Enter the weight in a tool like ShipStation’s calculator and it will return the rate by service type. For heavier packages, consider Flat Rate options.

Does USPS charge by weight or size?
The USPS charges by both weight and package size. While there are generally weight thresholds that determine rates, there are more factors to be aware of. If packages are small but heavy, they may receive cubic pricing discounts. Conversely, if a package is lightweight but large, dimensional weight may increase the rates. For a full breakdown of ShipStation’s USPS rates, read our guide to USPS rates.

How to Estimate Shipping Costs with FedEx
Our online shipping rates calculator estimates shipping cost based on the information you input, like how much the package weighs, its dimensions, the currency conversion rate (if you’re shipping internationally), and other factors. Your charges could be different from the estimate if any of these factors change. Why was my final shipment price more than originally quoted? Charges at the time of shipment might be different than those estimated if the package weight, dimensions, origin, destination, currency conversion rate, or other factors change between the time a customer receives an estimate and the time they actually ship the package.
