FedEx Ground Economy (SmartPost) vs UPS Ground Saver (SurePost) vs USPS Ground Advantage

If you ship lightweight packages to homes and the bill keeps climbing, the fix usually isn’t a new carrier. It’s the right economy service, used for the right packages. FedEx Ground Economy, UPS Ground Saver, and USPS Ground Advantage all do the same job: move a light residential parcel for less than standard ground. But they differ on speed, coverage, fees, and fine print, and all three have been renamed or rebuilt in the last few years. One of them changed its rules twice in two years. This guide explains how they compare and when each one wins.

The short answer

FedEx Ground Economy (formerly FedEx SmartPost) is FedEx’s lowest-cost residential ground service: 2 to 7 business days, up to 70 lbs.

UPS Ground Saver (formerly UPS SurePost) is the UPS equivalent: UPS Ground transit plus 1 to 2 days, up to 70 lbs, with final delivery by UPS or USPS.

USPS Ground Advantage is the Postal Service’s economy ground service: 2 to 5 business days, up to 70 lbs, no contract, and $100 of coverage included.

Use economy services for packages under 10 lbs. Above that, standard UPS Ground and FedEx Home Delivery are usually cheaper. For most shippers, the best answer is a mix.

What is FedEx SmartPost?

FedEx SmartPost is the former name of FedEx Ground Economy, FedEx’s low-cost ground service for lightweight residential packages, typically delivered in 2 to 7 business days. It started as a hybrid: FedEx moved packages most of the way, and USPS made the final delivery. Today FedEx Ground delivers most packages itself, and USPS handles final delivery only for PO boxes, U.S. territories, and military addresses.

The name changes, decoded

Every service on this page used to be called something else, which is why older guides, including many of the ones ranking on Google, get the details wrong.

FedEx SmartPost became FedEx Ground Economy. Same idea, current name. If a page still leads with “SmartPost,” its fees and rules are likely out of date.

UPS SurePost became UPS Ground Saver in 2025, then changed again. At the rename, UPS pulled delivery in-house, cut liability from $100 to $20 per package, and stopped delivering to PO boxes and military addresses. By early 2026, UPS had reversed much of that: USPS can again handle final delivery, PO box and military delivery is back, and liability is $50 per package. If a guide says Ground Saver can’t deliver to PO boxes, it was written in 2025.

USPS Ground Advantage launched in July 2023, replacing First-Class Package Service, Parcel Select Ground, and Retail Ground. It’s the service the other two are priced against.

The 10 lb rule

Economy services are built for light parcels, and their rates climb faster with weight than standard ground does. In our audits, the crossover is consistent: above 10 lbs, standard UPS Ground (residential) is typically cheaper than UPS Ground Saver, and FedEx Home Delivery is typically cheaper than FedEx Ground Economy. You also get faster transit and better liability terms.

Make it a routing rule in your shipping software: nothing over 10 lbs goes economy. It’s one of the most common and easiest-to-fix overcharges we see. Confirm the crossover against your own contract, since discounts can shift it, but start from 10 lbs.

Moving heavier boxes to UPS Ground or FedEx Home Delivery? Check whether they trigger large package or additional handling surcharges.

How economy pricing actually works

Carriers publish list rates for these services, but almost nobody pays them, and they change every year. What you actually pay is built in layers:

1. List rate, set by weight and zone. Published by each carrier on their official rate pages.
2. Minus your discount, if you have a contract or ship through a platform with one.
3. Subject to a minimum charge. Contracts often set a floor, so light packages may never see the full discount. The minimum can matter more than the discount percentage.
4. Plus fuel, which changes weekly for FedEx and UPS.
5. Plus per-package fees, like FedEx’s Delivery and Returns Surcharge, delivery area surcharges, and non-machinable or oversize fees.

That’s why two shippers with the “same” discount can pay very different amounts for the same package. The discount is the headline; minimums and fees usually decide the winner.

Getting access without a contract: FedEx and UPS offer these services on a contract basis, but shipping platforms like EasyPost, Shippo, Ship.com, and Amazon Buy Shipping offer them through their own carrier agreements, with no volume commitment. For small shippers, that’s often the easiest way in. Compare the platform’s rates against USPS Ground Advantage before switching.

FedEx Ground Economy: the details

Ground Economy is FedEx’s lowest-cost residential ground service and the direct descendant of SmartPost. Most packages move through FedEx Ground’s network and are delivered by FedEx. Packages to PO boxes, U.S. territories, and military addresses are handed to USPS for final delivery.

• Transit: 2 to 7 business days in the contiguous U.S., longer outside it. No guaranteed delivery date.
• Weight and size: 70 lbs max, 130 inches max length plus girth. FedEx also offers by-the-ounce rates for packages under 1 lb.
• Coverage: ships from the 48 contiguous states to all 50 states, U.S. territories, PO boxes, and military addresses.
• Access: FedEx contract, or through a shipping platform.
• Fees: no residential surcharge, but a per-package Delivery and Returns Surcharge on every package, plus delivery area, non-machinable, balloon (a light but bulky package billed at a higher minimum weight), and oversize rules. Dimensional weight uses a 139 divisor, and any fraction of an inch rounds up.

Best for: residential parcels under 10 lbs, including PO box, military, and Alaska or Hawaii destinations.

Watch out for: the per-package surcharge on every label, the non-machinable fee on long or bulky boxes, and a $100 liability limit with no option to declare more.

What Ground Economy doesn’t include: collect on delivery, money-back guarantee, declared value, signature proof of delivery, address correction, evening, appointment, or date-certain delivery, hold at a FedEx location, delivery redirects, and hazardous materials. If a shipment needs any of these, use FedEx Ground or Home Delivery. The address correction item matters: a bad address on Ground Economy won’t get fixed, so the package can come back to you.

UPS Ground Saver: the details

Ground Saver replaced SurePost in 2025, and its rules have changed since. Under UPS’s current terms, UPS moves the package through its ground network and final delivery is made by UPS or USPS, at UPS’s discretion.

• Transit: UPS Ground transit plus about 1 to 2 business days. No guaranteed delivery date. Delivery Monday through Saturday.
• Weight and size: 70 lbs max, 130 inches max length plus girth, no side over 60 inches, at least 4 inches high by 6 inches long. Packages under 1 lb must be under 864 cubic inches.
• Coverage: residential addresses, PO boxes, and military addresses. UPS’s product page also lists Alaska, Hawaii, Puerto Rico, and U.S. territories; confirm on your account, since UPS’s service terms list a narrower area.
• Access: UPS contract, or through a shipping platform.

Rules people miss:

• You can’t use UPS- or USPS-supplied boxes.
• No lithium batteries, hazmat, or other regulated items.
• One delivery attempt only; packages can be left without a signature.
• If USPS can’t deliver a package, it’s returned or destroyed at USPS’s discretion, and returns are billed USPS postage plus a fee.

Best for: residential parcels under 10 lbs for shippers already in the UPS workflow.

Watch out for: the $50 liability cap, with no UPS liability at all while the package is with USPS. And because UPS decides who delivers, your customer’s experience can vary by ZIP code.

USPS Ground Advantage: the details

Ground Advantage is the Postal Service’s economy ground service and the simplest option here: no contract and one carrier from pickup to doorstep.

• Transit: 2 to 5 business days, the fastest published window of the three.
• Weight and size: 70 lbs max, 130 inches max length plus girth.
• Coverage: every U.S. address, including PO boxes, military addresses, Alaska, Hawaii, and territories.
• No contract needed, and $100 of coverage included.
• Dimensional weight: for packages over 1 cubic foot, USPS divides by 139 and rounds every fraction of an inch up.
• Light packages: published commercial rates under 1 lb no longer vary by ounce. Some shipping platforms still offer ounce-based rates.

Best for: parcels under 5 lbs, shippers without a carrier contract, and anyone shipping to PO boxes, Alaska, or Hawaii.

Watch out for: cubic pricing rewards small, dense packages and punishes bulky ones, and USPS has added temporary increases on top of its annual price change.

Which one should you pick?

• Under 5 lbs, no carrier contract: USPS Ground Advantage. Usually the cheapest and fastest for small parcels, and it goes everywhere.
• Under 10 lbs, FedEx shipper: FedEx Ground Economy. Factor in the per-package surcharge.
• Under 10 lbs, UPS shipper: UPS Ground Saver. Check the $50 liability cap against your product values.
• Over 10 lbs: skip economy. Use UPS Ground residential or FedEx Home Delivery. They’re typically cheaper at these weights, and faster.
• High-value items: none of these is ideal. Insure separately or use a guaranteed service.

The honest answer for most shippers is a mix: Ground Advantage for the lightest parcels and odd destinations, your carrier’s economy service up to 10 lbs, and standard residential ground above that. The shippers overpaying are usually the ones sending everything through one service because nobody set up the routing rules.

Economy works best when customers know delivery takes a few extra days. Set that expectation at checkout.

The fourth option: regional carriers

For dense delivery zones, a regional carrier can beat all three national economy services on price, and often on speed. You don’t have to switch carriers to use one: route the zones where a regional carrier wins and keep everything else where it is. See how we match lanes to regional carriers, and hear why most shippers hesitate in Why Shippers Won’t Leave UPS and FedEx with Ben Emmrich of Tusk Logistics.

How to actually pay less, whichever you pick

1. Set routing rules. Economy under 10 lbs, standard residential ground above, USPS for PO boxes and remote destinations where it wins.
2. Audit the fees. Per-package surcharges, non-machinable fees, delivery area fees, and oversize rules quietly undo economy savings.
3. Renegotiate regularly. Economy discounts and minimums are contract terms. If yours are more than a year old, they’re probably stale.
4. Mind the box. All three carriers now use a 139 DIM divisor for larger packages. An extra inch can cost more than the service choice.
5. Claim what you’re owed. Lost and damaged economy packages are easy to write off. Don’t. See why parcel claims get denied.
