Is It Cheaper To Ship With UPS Or USPS?

March 23, 2023 Chase Flashman

UPS and USPS are two of the most popular couriers used to ship small parcels. Let’s compare the average shipping costs of the two. 

How Are Shipping Rates Determined For UPS And USPS? 

Shipping rates for UPS and USPS are determined based on various factors such as the package's weight, dimensions, destination, shipping speed, and any additional services required. 

Learning the nuances of UPS and USPS pricing can help you pick the suitable carrier for your needs. Let's begin with a deep dive into the criteria USPS uses to determine its rate structure.

USPS Shipping Rates

How USPS Determines Shipping Rates

Pricing of USPS services depends on the following factors: the weight of the package, the delivery time, the kind of package, and how far the item is going (the destination zone).

Size and Weight

Rates for USPS shipping services increase as the weight of the package  increases, or the shipping destination moves further, as illustrated in the example below:

$10.75

$11.35

$12.55

 

Note: Actual Weight Vs. Dimensional (DIM) Weight

The dimensional (volumetric) weight system is a pricing technique that allows shipping companies to charge fees based on package size rather than actual weight. With limited space on cargo trucks, DIM weight pricing helps carriers to mitigate losses from shipping large lightweight packages.

Shipping Speed / Delivery Time

Generally, the quicker the delivery, the more costly the shipping. For example, Priority Mail Express is USPS’s fastest domestic service and therefore costs more than other services like Priority Mail or First Class Mail.

UPS Shipping Rates 

How UPS Determines Shipping Rates 

UPS provides a variety of domestic and international shipping services, which are housed under these categories: Nationwide Shipping, Freight Shipping, International Shipping, and Flat-Rate Shipping. This article will focus on Nationwide (Domestic) and Flat Rate Shipping.

UPS, like USPS, factors package weight, zones, and delivery times when setting shipping rates. 

Ultimately, what you pay for your UPS shipment depends on the rate package you choose. Below are the rate packages that UPS offers:

Daily Rates - These rates will apply if you have a scheduled UPS pickup or have a UPS account that gives you access to daily rates.

Retail Rates - You should opt for retail rates if you do not have an account, do not have a scheduled pickup, or you're shipping from a UPS retail store. 

Flat Rate Shipping Within the U.S - With UPS Simple Rate, you choose from the five flat packaging rates and the four shipping speeds. 

Does UPS Charge By Weight Or Size?

UPS calculates shipping rates based on the total actual weight or the total dimensional weight of all packages in a shipment, whichever is greater.
