Capgemini puts last-mile at 53 percent of total parcel cost in 2024, up from 41 percent in 2018. After the 2026 carrier rate hikes, the share is higher. The right answer is not picking one carrier; it is rate-shopping every label across UPS, FedEx, USPS, and the regional networks that genuinely cover your zones.
TL;DR
The most-cited number in last-mile economics comes from Capgemini: the final leg from local delivery hub to consumer doorstep accounts for roughly 53 percent of the total cost of fulfilling an ecommerce order.[1] The same study put the share at 41 percent in 2018, which means the last mile has been a structurally faster-growing line item than middle-mile or first-mile freight for almost a decade.[1]
The drivers are not mysterious. Density on residential routes is lower than on commercial routes, which means each driver makes fewer stops per hour. Fuel, labor, and vehicle costs all climbed in 2024 and 2025. And every carrier has been moving the residential surcharge faster than the headline base rate, which front-loads the cost of residential delivery into the per-package math.
“The last mile accounts for 53 percent of the total cost of shipping, and consumer expectations of speed and convenience continue to push that share upward.”
The implication for any brand running ecommerce volume is that last-mile is the line where the most savings live. Putting one carrier on every label gives you a clean operations setup and almost guarantees you are paying 8 to 15 percent more than you should on at least 30 percent of your orders.
The 2026 reality is that no single carrier is the right answer for every SKU and every zone. A modern fulfillment operation rate-shops every label at the order line: USPS Ground Advantage for sub-1-lb residential to long zones; UPS Ground or FedEx Home for heavier shipments to short zones; regional carriers where they have density.
Carrier strength by package profile and lane
| Carrier | Sweet spot | Watch out for |
|---|---|---|
| USPS Ground Advantage | Sub-1 lb, residential, zones 5-8 | +8% surcharge through Jan 17, 2027 [3] |
| USPS Priority Mail | 1-3 lb, 2-day expectations | +6.6% base + 8% surcharge [3] |
| UPS Ground | 5-20 lb, commercial, zones 1-4 | DAS and EDAS add up fast |
| FedEx Home Delivery | Residential, dense metros | $6.45 residential surcharge [2] |
| OnTrac | Western US residential | Coverage limited to West / SW [4] |
| LSO | Texas and surrounding states | 5% GRI 2026, accessorials flat [4] |
| GLS | Western and SW US, 8 states | Density variable by metro [4] |
Ground Advantage launched in July 2023 as a hybrid 2-to-5-day product, folding First-Class Package Service, Parcel Select Ground, and Retail Ground into a single rate base.[5] It includes tracking, $100 in insurance, and Saturday delivery.[6] For sub-1-pound residential parcels in zones 5 through 8, Ground Advantage is still the cheapest national option even after the January and April 2026 hikes, with a structural DIM-divisor advantage (166 vs. UPS and FedEx’s 139) on bulky lightweight packages.[7]
UPS and FedEx are the right call for medium-weight (5 to 20 pound) parcels and for shipments to commercial addresses where the residential surcharge does not apply. Both raised base rates 5.9 percent for 2026, but effective increases for typical ecommerce shippers land closer to 7 to 12 percent once residential, DAS, EDAS, fuel, dimensional, and minimum-charge layers are applied.[8] The negotiated discount the carrier offers off published rates is the most important number on your contract; brands shipping above 1,000 packages per week should expect 30 to 60 percent off list on the right service lanes.
OnTrac, LSO (Lone Star Overnight), and GLS together cover most of the country west of the Mississippi with regional networks that often outperform UPS and FedEx on dense suburban routes inside their footprint. OnTrac claims delivery to roughly 75 percent of US shoppers, with per-parcel costs up to 30 percent lower than national carriers and no residential surcharge on its Ground Essentials product.[4] LSO took a 5 percent GRI on January 1, 2026 (lower than the 5.9 percent at UPS and FedEx) and held its accessorial fees flat.[4]
Residential surcharges are where the published base rate and the actual invoice diverge. UPS and FedEx have moved their residential add-ons faster than headline rates for years, and 2026 continued that pattern.
2026 residential surcharges (per package)
| Carrier | Service | 2025 | 2026 | Change |
|---|---|---|---|---|
| UPS | Ground residential | $6.55 | $6.95 | +6.1% |
| FedEx | Home Delivery residential | $5.95 | $6.45 | +8.4% |
| FedEx | Date Certain Home Delivery | - | Now per-package | Was per-shipment [2] |
| USPS | (no residential surcharge) | $0 | $0 | Structural advantage |
Beyond residential, both UPS and FedEx layer Delivery Area Surcharge (DAS) and Extended DAS (EDAS) on shipments going to ZIP codes the carrier classifies as rural or remote.[2] DAS lists for 2026 saw above-inflation increases and quietly added or recategorized hundreds of ZIP codes upward (commercial becoming residential, DAS becoming EDAS), so a parcel that was DAS in 2025 can be EDAS in 2026 without any rate-card line item changing.[8]
UPS and FedEx use a dimensional weight divisor of 139 on most domestic shipments. USPS holds at 166.[7] The lower the divisor, the more aggressively the carrier upcharges bulky lightweight boxes. A 12 by 12 by 12-inch box weighing 2 pounds bills at roughly 13 pounds on UPS or FedEx and at 11 pounds on USPS, which can shift the cheapest option for that exact package profile from one carrier to another.
USPS itself layered a time-limited 8 percent transportation surcharge on Priority Mail, Priority Mail Express, Ground Advantage, and Parcel Select effective April 26, 2026.[3] The surcharge runs through January 17, 2027, and stacks on top of the January 18, 2026 Competitive Products price increase. For a typical 2-pound Ground Advantage parcel, the cumulative year-over-year cost is up roughly 16 percent.[3] For sub-1-pound lightweight parcels, the cumulative increase is closer to 21 percent.
US carrier rates are zone-based, with zones running from 1 (very local) to 8 or 9 (coast-to-coast). Each zone band corresponds to a distance range from the origin ZIP. The cost increase per zone is not linear; it accelerates as you move outward.[9]
USPS Ground Advantage indicative pricing by zone (1 lb, 2026)

Indicative figures from published 2026 atoship analysis;[9] exact rates vary by commercial vs retail and weight oz/lb breakpoints.
A package shipped from a Kansas City origin reaches a coast-to-coast customer base in roughly zones 4 to 6 on average. The same package shipped from Los Angeles reaches an East Coast customer in zone 8. The structural geographic advantage shows up as a one-to-three-zone improvement on a typical national customer base, which translates directly into lower per-parcel cost on the weighted average.
For brands above $10 to $15 million in annual GMV, splitting inventory across two nodes (typically Kansas City paired with a coastal node, East or West) cuts the average shipping zone for a national customer base from roughly 5.2 down to roughly 3.4. On a 7.8 percent USPS Ground Advantage hike, that zone reduction more than offsets the rate increase on most order profiles. The trade-off is inventory carrying cost and operational complexity, which is why the move typically only pencils above the $10 million GMV mark.
The line between national and regional, and between premium and economy, has blurred in the last few years. USPS Ground Advantage itself is a hybrid (it merged three legacy products), and consolidator products like UPS SurePost and FedEx Ground Economy add another layer.
Launched July 9, 2023, Ground Advantage delivers in 2 to 5 business days for packages up to 70 pounds.[5] Local shipments (zones 1 to 3) typically arrive in 2 to 3 days; cross-country (zones 7 to 8) usually take 4 to 5 business days, occasionally longer.[6] Tracking, $100 insurance, and Saturday delivery are included at no extra charge.[6]
UPS SurePost and FedEx Ground Economy use the carrier’s line-haul to move parcels deep into the destination zone, then hand off to USPS for the actual last-mile drop. The result is a cost in between the carrier’s residential Ground rate and pure USPS, with transit times one to three days slower than pure UPS or FedEx ground. For high-volume, low-value DTC orders where transit speed is not the constraint, these products often pencil better than either pure carrier.
Zone skipping (consolidating outbound parcels onto a freight truck and injecting them into a destination-region USPS or carrier facility) remains the largest single mitigation lever for high-volume shippers, capturing 15 to 20 percent cost savings versus published rates when run well. Below roughly 500 parcels per day per destination region, partnering with a Parcel Select consolidator (DHL eCommerce, OSM Worldwide, PostNet) is the realistic path. After the September 2024 USPS NSA changes for DDU-injected parcels, the math is tighter than it used to be, so re-bidding the consolidator relationship in 2026 with current rate cards is essential.
The right time to optimize last-mile cost is not when the next GRI shows up. It is now. The realistic 60-day plan looks like this.
Pull every shipped parcel and re-cost it at January and post-April rates by weight band, zone, and service. The output is the actual dollar impact, not a press-release average.
OnTrac for Western residential, LSO for Texas and adjacent states, GLS for Western/Southwest. Even at 10 percent volume share initially, the competitive pressure improves the next national carrier RFP.
For your top 50 SKUs, calculate dimensional weight on USPS, UPS, and FedEx rule sets. Identify any SKU where a packaging redesign moves you into Ground Advantage Cubic eligibility, where the savings can be 15 to 28 percent on the right shape of order.
The residential and DAS surcharges are negotiable for shippers with real volume. Going into the next contract cycle with comparison rates from a second national carrier and a regional usually moves the surcharge by 50 cents to a dollar per parcel.
If you ship more than $10 million annually from a single warehouse, the incremental fixed cost of a second node almost certainly pencils against the cumulative 2026 rate hikes. Run the math on your actual zone distribution, not on industry averages.
