Postage is the one cost resellers treat as fixed. It is not, and this fall it moves three times in three months.
The Postal Service filed notice with its regulator on August 25 for a temporary price increase on Priority Mail Express, Priority Mail, USPS Ground Advantage and Parcel Select. Pending a favorable review, those prices take effect at 12 a.m. Central on October 4 and stay until 12 a.m. Central on January 17, 2027.[1]
That window covers every holiday sale you make. An item you list today will almost certainly ship at the higher price.
Here is what actually changes, what it costs by weight and zone, and the three things worth fixing before the first week of October.
What Actually Changes on October 4
USPS did not publish a flat surcharge. It raised the published prices themselves, and the size of the bump depends on how heavy the package is and how far it travels.
On the commercial schedule, which is the pricing tier that discounted marketplace labels are built from, the increases look like this:[1]
- Priority Mail and Ground Advantage to zones 1 through 4: $0.40 to $3.15
- Priority Mail to zones 5 through 9: $0.85 to $9.10
- Ground Advantage to zones 5 through 9: $0.55 to $7.70
- Priority Mail Express, all zones: $1.40 to $18.20
- Parcel Select: $0.40 to $2.35
Retail prices move more. Ground Advantage to zones 5 through 9 goes up $0.75 to $7.50 at retail, and Priority Mail Express tops out at $20.80.[1] Trade coverage puts the blended increase at roughly 6 percent across the affected services.[8][9]
The averages are the least useful number here. A light package going across town lands at the bottom of every range. A heavy one crossing the country lands near the top. One analysis of the commercial Ground Advantage schedule put a 0 to 3 pound package in zones 1 through 4 at $0.40 more, and a 26 to 70 pound package in zones 5 through 9 at $7.70 more.[8]
So the question is not "how much did postage go up." It is "how much did my packages go up," and the answer depends entirely on what you sell.
The 8 Percent You Are Already Paying
The October increase is not landing on a clean slate.
On April 26, USPS added an 8 percent transportation surcharge across Priority Mail, Priority Mail Express, Ground Advantage and Parcel Select, all weights and all zones.[4] It was the first time the Postal Service applied a fuel-style surcharge to package services, and it runs through January 17, 2027.
That end date is the same one attached to the holiday increase. Both charges are live on every qualifying package you ship this quarter.[9] Nothing expires in between.
This matters for how you read your own numbers. If your average label cost feels higher than it did last fall and you cannot point to a single announcement that explains it, this is why. The surcharge was folded into label pricing quietly, with nothing for sellers to do.[4] It shows up in what you pay, not in an invoice line you can see.
One practical note from the shippers who model this for a living: do not apply a blanket percentage to your shipping budget. Run the increase against your actual shipment history by weight and zone, because that is where the real exposure sits.[9]
eBay Moved USPS Rates Twice in August, and One of Them Helped You
If you buy labels through eBay, you already lived through two rate changes in two weeks. They went in opposite directions, and the gap between them is worth understanding.
On August 8, USPS raised Ground Advantage prices on packages weighing 3 to 5 pounds going to zones 5 through 8. Zone 5 went up $1.00. Zones 6, 7 and 8 each went up $2.00. eBay confirmed the change applies to labels bought through eBay Labels.[2]
Two weeks later, on August 22, the direction flipped. Ground Advantage rates came down for 2 pound packages across zones 1 through 8, and Priority Mail came down for packages up to 10 pounds going to zone 8.[3] Those reductions exclude rural ZIP codes.[3][10]
Put those together. A 2 pound box got cheaper almost everywhere. A 4 pound box going to zone 7 got two dollars more expensive. In fourteen days, the penalty for crossing from 2 pounds into the 3 to 5 pound band widened on both ends.
Sellers noticed the whiplash more than the savings. One commenter on the August reduction summed up the mood as "Spin the wheel and see what we'll charge this week."[10] Fair reaction. But the pattern underneath is not random: the cheap bands are getting cheaper and the heavy, far bands are getting more expensive, and October 4 pushes harder in the same direction.
If you have ever thought about switching from a bulky box to a smaller one, or pulling a pound of filler out of your packing, this is the quarter where that work pays.
The September 25 Deadline Most Sellers Missed
There is a second change happening this month, and it has an earlier deadline than the postage increase.
Some background on how calculated shipping works. When a listing uses calculated shipping, eBay figures the buyer's shipping charge from their address and your package details. You choose what rate the buyer sees: the standard carrier rate, eBay's discounted rate, or your own custom discounted rate.[5] eBay says its label rates average 33 percent off retail.[5]
That gap is real money. Plenty of sellers show the buyer the standard rate, buy the label at the discounted rate, and keep the difference to cover boxes, tape, labels and the final value fee they pay on the shipping amount.
eBay is closing that gap by default for a group of sellers. Sellers who received the notification email will have their calculated shipping listings switched to show eBay's discounted rates to buyers starting October 1. Those who want to keep their current setting can opt out by September 25, or change it back in their shipping preferences any time after October 1.[6]
Flat rate and free shipping listings are not affected.[5][6] eBay has done this before, defaulting select sellers to discounted rates in 2024.[5]
The timing is the part to sit with. Your buyer-facing shipping charge may drop on October 1. Your label cost goes up on October 4. If both happen to you and you do nothing, you absorb the squeeze from both sides in the same week.
Check your email for the notification. If you got it and the difference was funding your packaging, decide before September 25 rather than finding out from a payout.
What to Do in the Next Two Weeks
Five things, in priority order.
Weigh your top twenty sellers, packed. Not the item. The item in the box with the bubble wrap. Anything sitting between 2 pounds and 3 pounds is the highest-value thing you can fix this month, because the band below it got cheaper in August and the band above it got more expensive twice.
Reprice your free shipping listings. Free shipping means you eat the whole increase. Go through your free shipping inventory, find the heavy items and the ones that ship far, and either raise the price or switch them to calculated. A listing you create this week will ship under peak pricing.
Pull expedited free shipping off anything heavy. Priority Mail Express commercial rates go up as much as $18.20 a package.[1] There is almost no item in a normal reseller's inventory where absorbing that makes sense during peak.
Make the calculated shipping decision. Check whether you got the email. Decide by September 25.[6]
Know your carrier calendar if you ship outside USPS. UPS residential peak charges start at $0.50 in the shoulder weeks and reach $0.75 from November 22 through December 26, up from $0.60 last year. FedEx runs $0.50 in the shoulder weeks and $0.80 from November 23 through December 27, up from $0.65. UPS begins its oversize and nonstandard charges September 27 and broader residential charges October 25; FedEx starts September 28 and October 26.[7] Those dates come before the USPS increase, so a seller shipping bulky items through UPS or FedEx feels this two weeks earlier.
One more thing worth saying plainly: none of this is a reason to panic-raise prices across your whole store. The increase is measured in cents on small packages. It is measured in dollars on heavy ones going far. Fix the heavy ones. Leave the rest alone.
How ListForge Handles the Shipping Side for You
Most of the work above comes down to one thing: knowing the packed weight and dimensions of what you sell, and having the shipping configuration match reality instead of a default you set in 2023.
That is the part ListForge does while it builds the listing.
- Weight and dimensions get captured during research. When ListForge researches an item, it saves the package weight and dimensions it finds alongside the rest of the item data, so the numbers that drive your label price are attached to the item rather than typed from memory at publish time.
- Shipping is chosen from the item's economics, not a template. ListForge starts from the packed weight, dimensions, fragility and value, then compares the shipping burden against the listing price before picking calculated, buyer-paid flat, free, or local pickup. Free shipping only wins when the packed cost is small and predictable relative to the item's value. Being a small item is not enough on its own.
- Services come from your live eBay account. ListForge pulls the current shipping services available to you and uses the exact service code, rather than guessing at one that may have changed.
- Business policy users get weight-band matching. If you run eBay business policies, ListForge compares the item's packed weight against each policy's weight range and picks one that actually fits, instead of trusting a policy name. Policy names are labels; they tell you nothing reliable about handling, cost, or service behavior.
- The review screen is fully editable. Before anything publishes you can change shipping type, add or remove services, set the cost or mark it free, adjust handling time, and correct weight and dimensions. If you type 16 into the ounces box, ListForge rolls it into the pounds field rather than letting eBay reject the publish.
- Already-live listings can be edited too. You can stage changes to a published eBay listing, save them, and see exactly which fields eBay applied, rejected, or left unchanged. That is what you want when you are fixing shipping on fifty active listings before an October deadline.
Your postage cost is going up. The fix is not working harder on shipping settings. It is having the weight, the dimensions, and the service right the first time, on every listing, so the price you charge already reflects what the label actually costs.
Try ListForge free and see what your listings look like when shipping is figured out before you publish.
