Using flat rate shipping is a great way to cut costs for your Commerce business. Fortunately, top shipping couriers lake USPS, UPS, and FedEx all offer flat rate shipping and flat rate boxes.

Flat rate shipping from FedEx is called FedEx One Rate. Prior to 2013, only USPS offered flat rate options. But the massive popularity of flat rate shipping – or shipping rates that don’t vary by package weight and are thus “flat” – are only becoming more popular with merchants.

The top benefit of flat rate shipping is being able to send packages below a set weight to any location for one fixed price. Using flat rate helps merchants to predict their shipping costs, which is a key aspect of profitability in eCommerce.

This article will help you understand FedEx One Rate, what it costs, and how it compares to flat rate shipping from USPS and UPS. You'll also learn how to use the Easyship shipping rate calculator to find the cheapest shipping rates on all shipments – including FedEx flat rate.

What is FedEx One Rate?

One Rate is the FedEx version of flat rate shipping. One Rate lets you ship packages that weigh 50 pounds or less to anywhere in the US for a fixed price.

FedEx One Rate offers 12 free packaging options such as envelopes, flat rate boxes, tubes, and more. If your item fits within a flat rate package, and doesn’t exceed the weight limit, it can be sent to anywhere in the US for a fixed price.

Currently, FedEx One Rate is only available for US domestic shipments.

The Cost of FedEx One Rate

The cost of FedEx One Rates depends on three factors:

  • Delivery destination
  • Packaging choice
  • Speed of delivery

Since this is flat rate shipping, the weight of the package doesn’t impact the price. That said, your packaging choice could be considered as a sort of weight class, but I digress.

FedEx One Rate uses a system called delivery zones to price its services. Basically, delivery to each zone is priced differently based on distance:

  • Local Zone (1-2): Shipments moving between 0-150 miles
  • Regional Zone (3-4): Shipments moving between 151-600 miles
  • National Zone (5-9): Shipments moving over 601 miles

Base prices for FedEx Flat Rate in the Local Zone, or within 150 miles of your location vary by delivery timeline and package type. The cheapest FedEx One Rate option in the Local Zone is $8.90 for an envelope.

An extra-large box will cost you $32.35. Both will be delivered by the third day. Faster delivery is available, but it increases the cost. Delivery speeds for FedEx Flat Rate include:

  • Express Saver: Day 3 by 4:30 PM
  • 2Day: Day 2 by 4:30 PM
  • Standard Overnight: Next day by 3 PM
  • Priority Overnight: Next day by 10:30 AM
  • First Overnight: Next Day by 8 PM or 3:30 AM

Prices for FedEx One Rate are different in the three delivery zones. This next pricing chart shows FedEx flat rate prices in the Regional Zone, or for packages moving between 150-600 miles.

Now the cheapest envelope costs $9.50 and an extra-large box costs $36.60. That's a difference of about a dollar for the envelope, and about four dollars for the big box. Similar price increases can be seen at other shipping speeds and with different packaging.

Prices climb higher on FedEx One Rate shipments in the National Zone, or those being sent 600+ miles. These are cross-country shipments and include delivery to states like Hawaii and Alaska.

When shipping to Hawaii, say, you could do a lot worse than $11.55 for an envelope or $46.75 for an extra large box. Plus, FedEx has a reputation for being very reliable. If you’re a fan of USPS flat rate shipping, be sure to poke around the FedEx site to compare your current rates with FedEx.

The Benefits of FedEx One Rate

Price aside, FedEx flat rate carries several benefits for eCommerce merchants, including:

  • Free packaging:  FedEx One Rate packaging is free when you ship with FedEx Express services. Just order packaging in the sizes you need from the FedEx site, package, and ship.
  • Save time: Weighing packages and picking the right boxes feels like a waste of time. With FedEx flat rate, since weight isn't a factor, you'll use on standard box size that matches your item dimensions.
  • Predictable pricing: If you ship items of different sizes and weights, using FedEx One is one way to predictably reduce your shipping costs.
  • Reliability: Typically, FedEx One shipments are covered by the FedEx Money-back Guarantee. If a shipment was delayed, you could file for a return on postage. FedEx has suspended this policy, however, until COVID restrictions ease up.
