# USPS Priority Mail prices by weight and zone

**A 1 lb Priority Mail package costs $11.50 to $17.95 at the Post Office and $9.44 to $16.07 online, depending on the zone** (Zones 1-8; USPS's online price is its commercial price). 5 lb costs $15.10 to $39.00 at the counter and $12.04 to $30.93 online; 10 lb $18.60 to $63.40 and $15.15 to $43.03. Zone 9 (Palau, Micronesia and the Marshall Islands) costs about 2 times Zone 8. Every weight from 1 to 70 lb is in the tables below.

**Temporary holiday prices.** These include USPS's holiday add-on, from 12 a.m. CT Oct 4, 2026 to 12 a.m. CT Jan 17, 2027, on top of the 8% time-limited increase in place since Apr 26, 2026. [What it adds by weight and zone](https://resellerindex.com/rates/priority-mail/#holiday-h)

## How Priority Mail prices work

- **By the pound, rounded up.** "Any fraction of a pound is rounded up to the next whole pound," and the 1 lb price is the minimum per piece ([DMM 123.1.1](https://pe.usps.com/text/dmm300/123.htm)). Online prices round the same way ([DMM 223.1.1](https://pe.usps.com/text/dmm300/223.htm)). Notice 123's commercial table has a 0.5 lb row, but in this price list it equals the 1 lb price in every zone.
- **Zones** run from 1 (same 3-digit ZIP area or up to 50 miles) to 8 (beyond about 1,800 miles); Zone 9 is Palau, Micronesia and the Marshall Islands ([DMM 608.9](https://pe.usps.com/text/dmm300/608.htm)). [Why Zone 9 costs so much](https://resellerindex.com/rates/priority-mail/#zone-9).
- **Big light boxes pay dimensional weight.** Over 1 cubic foot (1,728 cubic inches), the price is set by the greater of actual weight and length x width x height (each side rounded up to the inch) divided by 139, rounded up ([DMM 123.1.3](https://pe.usps.com/text/dmm300/123.htm)). A 5 lb item in a 14 x 14 x 14 in. box bills as 20 lb: $29.34 online to Zone 4 instead of $16.37. A round or odd-shaped parcel's volume is first multiplied by 0.785, and a dimensional weight over 70 lb pays the 70 lb price ([DMM 123.1.3](https://pe.usps.com/text/dmm300/123.htm)). The divisor was 166 before Jul 12, 2026 ([tracker entry](https://resellerindex.com/changes/usps/2026-07-12-usps-dim-divisor-139/)). One loose end: for online labels, the DMM's steps for round or odd-shaped parcels still read the old way, sides rounded off to the nearest whole inch and divided by 166, while its rule for boxes uses 139 ([DMM 223.1.4.3](https://pe.usps.com/text/dmm300/223.htm), as of Oct 19, 2026).
- **Nonstandard fees** on top: $4.50 for a box over 22 in. up to 30 in. long, $21.00 over 30 in., $35.00 over 2 cubic feet, and $4.50 for tubes, rolls, cans, wooden or metal boxes and some liquids ([Notice 123](https://pe.usps.com/text/dmm300/Notice123.htm)). A box with both a length fee and a characteristics fee pays only the higher one, but a length or characteristics fee can stack with the over-2-cubic-foot fee ([DMM 123.1.6](https://pe.usps.com/text/dmm300/123.htm)). Ground Advantage charges less for the same boxes, $10.00 over 30 in. and $21.00 over 2 cubic feet at the counter and online, and Flat Rate packaging pays none of these fees.
- **Handling fees:** $7.50 for hazardous materials ([since Jul 12, 2026](https://resellerindex.com/changes/usps/2026-07-12-usps-hazmat-handling-fee/)) and $15.00 for live animals and perishables, at the counter and online ([Notice 123](https://pe.usps.com/text/dmm300/Notice123.htm)).
- **Included:** USPS Tracking and "up to $100 of insurance with most shipments (restrictions apply)"; the label needs a USPS Tracking barcode for that insurance, and extra insurance you buy replaces it rather than adding to it. USPS adds "No surcharges for fuel; residential or rural delivery; or Saturday delivery" ([USPS](https://www.usps.com/ship/priority-mail.htm)). The delivery objective is 2 to 3 days, not guaranteed ([DMM 123.2.1](https://pe.usps.com/text/dmm300/123.htm)).

## What Priority Mail costs over Ground Advantage

At USPS's published prices, Priority Mail is never cheaper than Ground Advantage at the same weight and zone, online or at the counter, from 1 to 70 lb: the smallest gap is $0.81 online and $1.15 at the counter. The gap is what you pay for USPS's 2-3 day objective against 2-5 days ([USPS](https://www.usps.com/ship/mail-shipping-services.htm)). Heavy items can beat both in a [Flat Rate box](https://resellerindex.com/rates/priority-mail-flat-rate/).

## When a Flat Rate box beats Priority Mail by weight

The weight above which each box costs less than a by-weight Priority Mail label, online. Every price, retail too, and the Ground Advantage comparison: [Flat Rate prices](https://resellerindex.com/rates/priority-mail-flat-rate/#vs-h).

*Online (commercial) prices, Notice 123 effective Oct 4, 2026. "over 11 lb" means a package heavier than 11 lb.*

| Flat Rate (online) | Zone 1 | Zone 2 | Zone 3 | Zone 4 | Zone 5 | Zone 6 | Zone 7 | Zone 8 | Zone 9 |
| --- | ---: | ---: | ---: | ---: | ---: | ---: | ---: | ---: | ---: |
| Small Box $12.95 | over 7 lb | over 6 lb | over 3 lb | over 2 lb | any weight | any weight | any weight | any weight | any weight |
| Medium Box $22.02 | over 20 lb | over 20 lb | over 15 lb | over 11 lb | over 4 lb | over 3 lb | over 3 lb | over 3 lb | any weight |
| Large Box $32.75 | over 25 lb | over 24 lb | over 23 lb | over 21 lb | over 10 lb | over 7 lb | over 5 lb | over 5 lb | any weight |

## Priority Mail Cubic: priced by box size

Online customers with PC Postage or a permit can pay by package size instead of weight: five tiers up to 0.5 cubic foot, for pieces up to 20 lb and 22 in. on the longest side (it was 18 in. before Jul 12, 2026, [DMM archive](https://pe.usps.com/Archive/NHTML/DMMArchive20260406/223.htm)), not rolls or tubes ([DMM 223.1.3](https://pe.usps.com/text/dmm300/223.htm)). Measure each side, round down to the 1/4 inch, multiply and divide by 1,728. DMM 223.1.3.1 lists cubic for registered PC Postage users, permit imprint customers and permit holders using USPS Returns for packages returned at Priority Mail prices, and sets a minimum only for permit imprint mailings ("at least 200 pieces or 50 pounds of mail"); Click-N-Ship isn't on that list.

*USD, cubic feet up to. Notice 123 effective Oct 4, 2026, Priority Mail Commercial Cubic (matches PM Comm Cubic.csv).*

| Tier | Zone 1 | Zone 2 | Zone 3 | Zone 4 | Zone 5 | Zone 6 | Zone 7 | Zone 8 | Zone 9 |
| --- | ---: | ---: | ---: | ---: | ---: | ---: | ---: | ---: | ---: |
| 0.10 cu ft | $9.46 | $9.74 | $10.13 | $10.90 | $13.87 | $15.54 | $16.24 | $16.36 | $33.94 |
| 0.20 cu ft | $9.50 | $9.79 | $10.18 | $11.19 | $14.02 | $16.19 | $17.16 | $17.22 | $35.79 |

- **Some tiers are just weight prices:** tier 0.20 costs exactly the 2 lb price and tier 0.30 costs exactly the 3 lb price, in every zone.
- **The smallest tier costs more than 1 lb by weight**, by $0.02 to $0.61 depending on zone, so cubic only helps once a small box weighs more.
- **Where cubic wins:** tier 0.10 beats by-weight Priority Mail for packages over 1 lb, then 0.20 over 2 lb, 0.30 over 3 lb, 0.40 over 4 lb and 0.50 over 5 lb, the same in every zone (up to the 20 lb cubic limit).
- **Ground Advantage Cubic is cheaper at the same tier**, by at least $1.06, and goes to 1 cubic foot: [Ground Advantage Cubic rates and how tiers work](https://resellerindex.com/rates/ground-advantage-cubic/).

## Holiday prices until Jan 17, 2027

Every Priority Mail price above includes USPS's temporary add-on from 12 a.m. CT Oct 4, 2026 to 12 a.m. CT Jan 17, 2027 ([USPS, Aug 25, 2026](https://about.usps.com/newsroom/national-releases/2026/0825-usps-announces-temporary-price-change-for-2026-holiday-shipping-season.htm), PRC Docket CP2026-10). Today's price minus the add-on is the Jul 12, 2026 price: a 1 lb label to Zone 4 was $10.40 online, and a 5 lb one $15.72.

*Holiday add-on per piece, USD, by billed weight (USPS announcement of Aug 25, 2026). Flat Rate add-ons are on the [Flat Rate page](https://resellerindex.com/rates/priority-mail-flat-rate/#holiday-h).*

| Weight | Post Office, Zones 1-4 | Post Office, Zones 5-9 | Online, Zones 1-4 | Online, Zones 5-9 |
| --- | ---: | ---: | ---: | ---: |
| 0-3 lb | $0.50 | $1.00 | $0.40 | $0.85 |

| 26-70 lb | $3.90 | $9.10 | $3.15 | $9.10 |

On Jan 17, 2027 the add-on ends, and so does the 8% time-limited increase from Apr 26, 2026 ([tracker entry](https://resellerindex.com/changes/usps/2026-04-26-usps-time-limited-8-percent/)). As of Oct 19, 2026, USPS hadn't published the Priority Mail prices that apply from Jan 17, 2027, so we don't show a forecast.

## Priority Mail 1 lb and 5 lb since 2007

At the Post Office to Zone 4, a 1 lb package cost $4.60 on May 14, 2007 and costs $12.40 now; 5 lb went from $8.90 to $18.30. Until Jan 4, 2010 the 1 lb price was the same to every zone ($4.95 from Jan 18, 2009, [Postal Bulletin 22247](https://about.usps.com/postal-bulletin/2008/html/pb22247/html/kit_006.html)); USPS zoned it that day ([Postal Bulletin 22273](https://about.usps.com/postal-bulletin/2009/pb22273/html/kit.htm)).

## Questions

### How much does Priority Mail cost for 1 lb?

$11.50 to $17.95 at the Post Office and $9.44 to $16.07 online, Zones 1-8; Zone 9 is $35.25 and $33.33 ([USPS Notice 123](https://pe.usps.com/text/dmm300/Notice123.htm)). Anything under 1 lb pays the 1 lb price: it's the minimum ([DMM 123.1.1](https://pe.usps.com/text/dmm300/123.htm)). Online, Notice 123 also lists a 0.5 lb price, but it equals the 1 lb price in every zone.

### How much is Priority Mail for 5 lb and 10 lb?

5 lb: $15.10 to $39.00 at the Post Office, $12.04 to $30.93 online. 10 lb: $18.60 to $63.40 and $15.15 to $43.03 (Zones 1-8). A Medium Flat Rate Box is $25.80 ($22.02 online) at any weight up to 70 lb ([Flat Rate prices](https://resellerindex.com/rates/priority-mail-flat-rate/)).

### Is Priority Mail cheaper online?

Yes: USPS's commercial prices, for Click-N-Ship and PC Postage labels ([DMM 223.1.2](https://pe.usps.com/text/dmm300/223.htm)), are 1% to 37% below the counter price across every weight and zone; at 1 lb that's $0.18 to $2.28. Label services and platforms can have their own rates.

### Is Priority Mail ever cheaper than Ground Advantage?

Not by weight at USPS's published prices: at every weight from 1 to 70 lb and every zone, Priority Mail costs at least as much as Ground Advantage, online and at the counter. At 1 lb online it's $1.43 to $5.40 more (Zones 1-8). Priority Mail's case is speed (2-3 days against 2-5 for Ground Advantage, [per USPS](https://www.usps.com/ship/mail-shipping-services.htm)) and Flat Rate, which beats both for items heavy for their size ([from what weight](https://resellerindex.com/rates/priority-mail-flat-rate/#vs-h)).

### Why is Priority Mail to Zone 9 so expensive?

Zone 9 is Palau, Micronesia and the Marshall Islands, which USPS mails as domestic mail ([DMM 608.2.2](https://pe.usps.com/text/dmm300/608.htm)). A 1 lb Priority Mail package costs $35.25 there at the counter, 2.0 times the Zone 8 price ($17.95). Flat Rate costs the same as anywhere: $25.80 for a Medium box.

### How big can a Priority Mail package be?

Up to 70 lb ([DMM 123.2.1](https://pe.usps.com/text/dmm300/123.htm)) and 108 inches in combined length and girth ([USPS](https://www.usps.com/ship/priority-mail.htm)). Boxes over 1 cubic foot pay dimensional weight if it's higher ([DMM 123.1.3](https://pe.usps.com/text/dmm300/123.htm)), and long or bulky boxes pay nonstandard fees: $4.50 over 22 in., $21.00 over 30 in., $35.00 over 2 cubic feet ([Notice 123](https://pe.usps.com/text/dmm300/Notice123.htm)). Flat Rate packaging is exempt ([DMM 123.1.6](https://pe.usps.com/text/dmm300/123.htm)).

### How does USPS round Priority Mail weight?

Up, to the next whole pound: "if a piece weighs 1.2 pounds, the weight (postage) increment is 2 pounds" ([DMM 123.1.1](https://pe.usps.com/text/dmm300/123.htm)). So a 2 lb 1 oz package pays the 3 lb price, $13.08 online to Zone 4 instead of $11.19.

### When do Priority Mail holiday prices end?

At 12 a.m. CT on Jan 17, 2027 ([USPS, Aug 25, 2026](https://about.usps.com/newsroom/national-releases/2026/0825-usps-announces-temporary-price-change-for-2026-holiday-shipping-season.htm)), together with the 8% time-limited increase that started Apr 26, 2026, which USPS said "would remain in place until midnight Central Time on Jan. 17, 2027" ([USPS, Mar 25, 2026](https://about.usps.com/newsroom/national-releases/2026/0325-usps-announces-transportation-related-time-limited-price-change.pdf)). As of Oct 19, 2026, USPS hadn't published the Priority Mail prices that apply from Jan 17, 2027, so we don't show a forecast.

## How we built this

Every price is from the current [Notice 123](https://pe.usps.com/text/dmm300/Notice123.htm), read on Oct 19, 2026, and matches USPS's [price change file](https://pe.usps.com/resources/PriceChange/Time-Limited%20OCT%202026%20Price%20Change%20-%20Notice%20123%20-%20Final.zip) cell for cell. We also checked that each one equals the [Jul 12, 2026 price](https://pe.usps.com/Archive/NHTML/DMMArchive20260712/Notice123.htm) plus the add-on USPS announced. Comparisons are computed from those tables at USPS's published prices; label services and selling platforms can charge less.
