USPS Cubic Pricing

What is USPS Cubic Pricing?

USPS Cubic Pricing provides high-volume shipping customers with discounted rates for small, heavy packages. Priority Mail® packages measuring less than 20 pounds in weight and 0.5 cubic feet in volume, with no dimension longer than 18 inches, are eligible for Cubic Pricing as long as you meet the minimum package requirements. For these packages, customers will pay shipping costs for the actual size of the package and the shipping distance instead of its weight. To qualify for Cubic Pricing, customers must ship over 50,000 packages a year.

How does Cubic Pricing work?

The cubic pricing for your USPS package is measured by calculating:

Length x Width x Height / 1728 = Cubic Feet

Note: All measurements should be rounded down to the nearest 0.25 inch. No dimension may exceed 18 inches to be eligible for Cubic Pricing.

Once you have the cubic feet measurement, your package will fall into one of five tiers:
  • Tier 1: Packages up to .10 cubic feet
  • Tier 2: Packages more than .10 and up to .20 cubic feet
  • Tier 3: Packages more than .20 and up to .30 cubic feet
  • Tier 4: Packages more than .30 and up to .40 cubic feet
  • Tier 5: Packages more than .40 and up to .50 cubic feet

As an example, an 8″ length x 6″ height x 8″ width (Tier 3) package weighing 8 pounds and being shipped to Zone 6 would cost $21.53 using Priority Mail Commercial Base rates. The same package would cost only $13.48 with USPS Cubic Pricing. That is a 37% savings!
