Which packages pay the 25 lb price
- From 1 lb, USPS rounds any fraction of a pound up, so anything over 24 lb up to 25 lb pays the 25 lb price: a 24 lb 1 oz package costs the same as a 25 lb one (DMM 283.1.1).
- Go over 25 lb, even to 25 lb 1 oz, and it pays the 26 lb price: $3.05 to $10.56 more online and $3.80 to $8.40 more at the Post Office, depending on the zone. Part of that step is the holiday add-on, which goes from $1.05 to $3.15 online in Zones 1-4 and from $1.75 to $7.70 in Zones 5-9 at 26 lb.
- A 24 lb package costs $1.88 to $9.22 less online and $1.20 to $3.60 less at the Post Office.
Cheaper ways to ship 25 lb

Priority Mail Flat Rate costs the same at any weight up to 70 lb, so at 25 lb these cost less than Ground Advantage online: the Flat Rate Envelope ($11.97 online, 12-1/2 x 9-1/2 in. or smaller) in Zones 1-9, the Legal Flat Rate Envelope ($12.51 online, 15 x 9-1/2 in.) in Zones 1-9, the Padded Flat Rate Envelope ($12.84 online, 12-1/2 x 9-1/2 in.) in Zones 1-9, the Small Flat Rate Box ($12.95 online, 8-5/8 x 5-3/8 x 1-5/8 in. inside) in Zones 1-9, the Medium Flat Rate Box ($22.02 online, 11 x 8-1/2 x 5-1/2 in. or 13-5/8 x 11-7/8 x 3-3/8 in. inside) in Zones 1-9 and the Large Flat Rate Box ($32.75 online, 12 x 11-3/4 x 5-1/2 in. inside) in Zones 4-9.

- Media Mail, if it qualifies: $22.07 to any zone, $4.30 to $57.87 less than an online Ground Advantage label. Only books (at least 8 pages), CDs, DVDs and the other media on USPS's list qualify, not video games (USPS; what qualifies). Guides: books · video games.
- Buy the label online: $7.28 to $19.16 less than the counter at this weight (17% to 23%), the most in Zones 8 and 9.
- No cubic prices at this weight. USPS's cubic prices stop at 20 lb (DMM 283.1.3), so a 25 lb package pays by weight.
- Watch the box size. A 25 lb package is billed at its actual weight unless its box is over 3,475 cubic inches (sides rounded up to the inch); above that, length x width x height divided by 139 is more than 25 lb and sets the price (DMM 283.1.4). Any box that big is also over 2 cubic feet (3,456 cubic inches). On top: $4.50 over 22 in. long, $10.00 over 30 in., $21.00 over 2 cubic feet, and the oversized price over 108 in. in length plus girth (all fees).

25 lb is the heaviest weight in USPS's 11-25 lb band, so a package just over it pays the 26 lb price and a bigger add-on: $1.05 becomes $3.15 online in Zones 1-4, and $1.75 becomes $7.70 in Zones 5-9.
On Jan 17, 2027 the holiday add-on ends, and so does USPS's 8% time-limited increase, in place since Apr 26, 2026 (tracker entry). USPS's Governors ordered prices "rolled back to approved levels" then (Governors' Decisions 26-1 and 26-7).

What is the cheapest way to ship a 25 lb package?
If it's books, CDs, DVDs or other media on USPS's list, Media Mail: $22.07 to any zone, in 2-8 days against 2-5 for Ground Advantage (USPS). Otherwise, at published online prices: the Flat Rate Envelope in Zones 1-9 ($11.97), if the item fits the Flat Rate packaging. Keep the box at 3,475 cubic inches or less so it's billed at its actual weight.
What if my package weighs a little more than 25 lb?
It pays the 26 lb price. USPS rounds up any fraction of a pound (DMM 283.1.1), so a 25 lb 1 oz package costs $3.05 to $10.56 more online and $3.80 to $8.40 more at the Post Office than a 25 lb one.
Will a 25 lb package cost less after Jan 17, 2027?
The holiday add-on ends at 12 a.m. CT on Jan 17, 2027. At 25 lb it is $1.05 online and $1.25 at the Post Office in Zones 1-4, and $1.75 and $2.75 in Zones 5-9 (USPS). Before it started on Oct 4, 2026, the same package cost $25.32 to $78.19 online. USPS's 8% time-limited increase ends the same day. USPS's Governors ordered both temporary increases "rolled back to approved levels" at 12 a.m. on Jan 17, 2027 (Governors' Decisions 26-1 and 26-7); the restored prices apply "unless the Governors take further action to adjust prices." USPS filed those prices with the Postal Regulatory Commission (Dockets CP2026-4 and CP2026-10), but they aren't in a Notice 123 price list yet, so this page shows no price from Jan 17, 2027, and the earlier prices above aren't a forecast.
Is Priority Mail Flat Rate cheaper than Ground Advantage for a 25 lb package?
In Zones 1-9, yes, if the item fits: the Flat Rate Envelope costs $11.97 online and beats Ground Advantage online in Zones 1-9, the Legal Flat Rate Envelope costs $12.51 online and beats Ground Advantage online in Zones 1-9, the Padded Flat Rate Envelope costs $12.84 online and beats Ground Advantage online in Zones 1-9, the Small Flat Rate Box costs $12.95 online and beats Ground Advantage online in Zones 1-9, the Medium Flat Rate Box costs $22.02 online and beats Ground Advantage online in Zones 1-9 and the Large Flat Rate Box costs $32.75 online and beats Ground Advantage online in Zones 4-9. Flat Rate prices don't depend on weight up to 70 lb, so the heavier the item, the more often they win; by weight, Priority Mail costs $3.92 to $158.09 more than Ground Advantage at 25 lb (Notice 123).
Does a package just over 25 lb pay a bigger holiday add-on?
Yes. 25 lb is the top of USPS's 11-25 lb holiday band. Over it, the package pays the 26 lb price, and the add-on inside that price goes from $1.05 to $3.15 online in Zones 1-4 and from $1.75 to $7.70 in Zones 5-9, until Jan 17, 2027 (USPS).
