2026 peak season surcharges: FedEx, UPS and USPS full schedule

Two of the three national carriers have published 2026 holiday pricing. FedEx demand surcharges begin September 28, 2026. USPS temporary holiday prices begin October 4, 2026. Both run through January 17, 2027. UPS has not announced its 2026 schedule as of August 25, 2026.

The three carriers price peak in structurally different ways, which matters more than the headline numbers. FedEx adds flat per-package fees on top of your normal rate. USPS raises the underlying price of the service itself for the window. UPS has historically used volume-indexed demand surcharges that scale with how far above your baseline you ship. Comparing them requires pricing an actual shipment, not comparing published fee tables.

FedEx announced its 2026 U.S. peak season surcharges on July 22, 2026. They arrive in two waves and step up for the holiday window. All amounts are per package, on top of the transportation charge and any surcharge that already applied.

Express amounts exclude FedEx One Rate. Ground Economy is contract-only. The fees that rose most versus 2025 are Ground Residential (+23.1%) and overnight Express (+21.4%) — the two that touch the most e-commerce volume.

Full breakdown, including which fees you can engineer around: FedEx 2026 peak season surcharges — every fee and date.

As of August 25, 2026, UPS has not published a 2026–27 peak season demand surcharge schedule. We are not going to print a number we cannot source, so this section stays empty until UPS publishes.

What is known, and what is not:

• Not announced: the 2026–27 demand periods, the per-package amounts by service, and the volume thresholds that determine whether a shipper is assessed at all.
• This is a checked finding, not an assumption. As of August 25, 2026, ups.com/peaksurcharge — the shortlink UPS itself points shippers to — still resolves to the demand-surcharge PDF dated "August 28, 2025 Update," whose demand periods run September 28, 2025 to January 17, 2026 and have expired. UPS has not replaced it.
• Historical timing only: UPS has typically published in late August or early September; the 2025–26 schedule posted August 28, 2025. That is a pattern, not a commitment, and it tells you nothing about the 2026 amounts.
• Be careful what you read elsewhere. Several third-party "UPS 2026 peak surcharge" tables currently circulating are restatements of the expired 2025 schedule, or are mixing in UPS's separate 2026 general rate increase residential figures, which are a different charge entirely. If a number is not on a UPS document, we will not print it.
• Structurally different from FedEx: UPS demand surcharges have historically been volume-indexed — assessed on shippers whose peak volume runs above a baseline calculated from earlier in the year — rather than applied flat to every package. If that structure holds, a small shipper and a large one can face very different effective costs from the same published table.

The moment UPS publishes, this section is replaced with the full fee table by service and date range, and a dedicated UPS page goes up alongside the FedEx one. The date at the top of this page tracks that update. In the meantime, the year-round UPS Additional Handling criteria still apply and are worth auditing now, because dimension-triggered fees are the ones you can still design out before October.

If you are re-shopping economy residential service before peak, the UPS economy vs FedEx Ground Economy comparison is the relevant read — with the caveat that only the FedEx side of that comparison has a known 2026 peak adder so far.

USPS announced its 2026 holiday temporary price change on August 25, 2026, filed with the Postal Regulatory Commission under Docket No. CP2026-10. Pending PRC review, temporary prices take effect at 12 a.m. CT on October 4, 2026 and remain in place until 12 a.m. CT on January 17, 2027.

Unlike FedEx, USPS does not add a separate per-package fee. It raises the price of the service for the window. Affected products: Priority Mail Express, Priority Mail, USPS Ground Advantage, and Parcel Select.

Increases scale with weight and zone. Selected published amounts:

The complete zone-by-zone tables are in the PRC filing. Reporting of that filing puts the average increase at about 6% across the affected products, but note that the 6% figure is from the filing as reported in the trade press, not from the USPS release itself, which gives only dollar amounts.

The part that is easy to miss: this stacks on a separate 8% temporary price increase USPS put in place on April 26, 2026, which also runs to January 17, 2027 and hits the same four products. USPS does not call that one a surcharge — its own language is a "time-limited price change," an 8% increase to base postage prices rather than a separately itemized line, and USPS explicitly says it has avoided surcharges. Much of the trade press calls it a fuel surcharge; that is shorthand, not the mechanism. Either way, between October 4, 2026 and January 17, 2027 a USPS parcel on these services carries both increases.

And both sit on top of the July 12, 2026 dimensional weight change, which moved the USPS divisor from 166 to 139 and started rounding fractional dimensions up to the next full inch. If you have not re-measured your boxes since June, the billable weight your holiday rates are calculated from may already have moved.

Abstract fee tables make peak feel bigger or smaller than it is. Here is a real one.

Take a 10 lb package in a 16 × 14 × 12 in box going NYC to Dallas (Zone 5), residential. On June 22, 2026, the ShipWave Parcel Rate Index quoted that exact package at FedEx Ground $18.31, UPS Ground $24.70, USPS Ground Advantage $22.23 — commercial rates, pulled live on a single day.

• Shipped October 20: FedEx Ground Residential carries no demand surcharge yet — Phase 2 does not start until October 26. The box is compact enough not to trigger Additional Handling. Peak cost: $0.00.
• Shipped December 1: the same package now carries the $0.80 Ground Residential peak surcharge. Peak cost: $0.80, about 4.4% on that base rate.

Now look at the number next to it. The spread between the cheapest and most expensive carrier on that same box, on that same day, was $6.39 — roughly eight times the entire FedEx peak surcharge. Across the full index, the same-box ground spread averaged 129%.

That is the honest framing of peak season for most small and mid-size shippers: the surcharge is real and it compounds at volume, but for a normal, well-packed parcel it is dwarfed by the carrier you happened to pick. The expensive mistakes are (a) shipping every package on one carrier out of habit, and (b) letting a box trip Additional Handling, which at $11.85 in the peak window costs more than fifteen residential adders.

Every peak fee falls into one of two buckets, and confusing them wastes the entire planning window.

Dimension-triggered — you can design these out. Additional Handling, Oversize, and the Ground Unauthorized Package Charge respond to how you pack. They are triggered by a longest side, a second-longest side, a length-plus-girth total, an actual weight threshold, or packaging that is not fully encased in corrugate. At FedEx's peak-window rates these are the expensive ones by an order of magnitude: $11.85, $117.25, and $595.00 per package respectively. Changing a carton spec is the highest-return thing you can do between now and September 28. Check yours with the surcharge checker and read how length plus girth is measured before you order peak packaging.

Service-attached — you can only re-shop these. FedEx's residential, Home Delivery, Ground Economy and Express adders, and the USPS temporary holiday prices, attach to the service you chose. No packaging change removes them. The only lever is whether that service, on that lane, at that weight, is still the lowest total landed cost once the peak amount is applied. That is a per-shipment comparison, and it changes by zone and weight — which is precisely why a single "cheapest carrier" answer does not survive peak season.

One structural note worth planning around: FedEx surcharges Ground Economy hardest of its four service adders, at $4.05 per package in the peak window versus $0.80 for Ground Residential. Cheap economy services are being repriced toward the middle for the holiday window. Verify, do not assume.

1. Right-size against divisor 139, not 166. USPS moved to a 139 divisor with round-up on July 12, 2026, matching UPS and FedEx. Boxes that were dimensionally safe in the spring may be billing heavier now, and a package that gains an inch can also cross an Additional Handling threshold. Re-run your top SKUs through the dimensional weight calculator.

2. Re-shop your economy residential lane. FedEx Ground Economy takes a $4.05 peak adder while USPS raises Ground Advantage by a published amount that varies by weight and zone. The answer that was cheapest in September may not be cheapest in December, and it may differ by zone within the same week.

3. Consolidate residential shipments. Peak fees are charged per package. Two boxes to the same address in the peak window pay the residential adder twice, and if either trips Additional Handling the penalty doubles too. Combining orders is one of the few levers that reduces fee count rather than fee size.

4. Audit your invoices during the window, not after. Peak is when misapplied Additional Handling and residential classifications spike, and dispute windows are short. The carrier invoice audit tool gives you a starting estimate of what is recoverable.

Operational side of peak — staffing, supplies, cutoffs — is covered separately in the peak season preparation checklist and the holiday shipping deadlines tool.
