What Does “Stamp Cost” Mean?

The word cost can refer to several different numbers. Separating them prevents misleading comparisons.

USPS postage value

The amount a stamp contributes toward the required mailing charge. A current one-ounce Forever stamp contributes $0.82, even if the owner bought it years ago for less.

Product selling price

The amount a retailer lists for a book, sheet, roll, or other package. Always confirm the number and type of individual stamps included.

Delivered purchase cost

The final amount paid after applicable shipping or order charges. Use this figure—not a headline price alone—when comparing purchases.

Total mailing cost

The postage required for the finished mailpiece after considering weight, shape, size, destination, surcharges, and extra services.

For example, 100 Forever stamps have a combined current postage value of $82.00 because 100 × $0.82 = $82.00. Their selling price can differ from that amount. See the discount Forever stamp comparison for a detailed savings calculation.

How Much Is a Forever Stamp Worth Today?

A domestic Forever stamp follows the current First-Class Mail single-piece one-ounce stamped-letter price. Its value is based on the rate in effect when it is used, not the price printed on a receipt years earlier.

That means an unused Forever stamp bought when rates were lower can still pay the current one-ounce base rate for a qualifying letter. As of July 12, 2026, its postage value is $0.82.

Price, value, and purchase date

  • Current value: $0.82 toward eligible postage.
  • Original purchase price: what the buyer paid when the stamp was purchased.
  • Retail package price: what a seller currently charges for a specified quantity.

These figures answer different questions and should not be substituted for one another.

First-Class Mail Letter Cost by Weight

For ordinary retail stamped letters that qualify as standard machinable domestic letters, the USPS table effective July 12, 2026 is:

Weight not overRequired postageConvenient example
1 ounce$0.821 Forever stamp
2 ounces$1.111 Forever + 1 Additional Ounce stamp
3 ounces$1.401 Forever + 2 Additional Ounce stamps
3.5 ounces$1.691 Forever + 3 Additional Ounce stamps

A letter weighing more than 3.5 ounces is no longer priced in this ordinary letter table. Square, rigid, uneven, or otherwise nonmachinable envelopes may also require a surcharge. Large envelopes start at a different base price.

Prices for Other Common Stamp Types

Additional Ounce stamp: $0.29

This stamp supplements base postage for a qualifying heavier letter. It does not replace the $0.82 one-ounce base amount by itself.

Two-ounce stamp: $1.11

A nondenominated stamp labeled for the two-ounce stamped-letter category follows that category's current value. It can be convenient when a qualifying letter weighs more than one ounce but no more than two ounces.

Three-ounce stamp: $1.40

A stamp labeled for the three-ounce stamped-letter category follows the applicable current category value. Shape and other mailing characteristics still matter.

Domestic postcard: $0.65

The postcard price applies only when the card meets USPS postcard standards. An oversized or unusually prepared card may be charged as a letter or another mailpiece type.

Global Forever stamp: $1.75

A Global Forever stamp follows the current one-ounce First-Class Mail International letter price. International prices beyond the base ounce vary by destination price group and weight.

How to Calculate the Cost of Mailing a Letter

  1. Assemble the mailpiece first. Include all pages, cards, photographs, reply envelopes, and inserts.
  2. Weigh it accurately. A fraction over a weight step can move the letter into the next price level.
  3. Check its shape and dimensions. Decide whether it is a letter, postcard, large envelope, or package.
  4. Check machinability. Square, rigid, uneven, or unusually shaped letters may need a surcharge.
  5. Confirm destination and services. International mail and services such as Certified Mail add other prices or fees.
  6. Add valid postage. The total value affixed must meet at least the required amount.

Standard two-ounce letter: $0.82 base postage + $0.29 additional ounce = $1.11

Standard three-ounce letter: $0.82 base postage + $0.58 for two additional ounces = $1.40

One-ounce large envelope: use the separate flat price of $1.69, not the $0.82 letter price.

When the category is uncertain, use an official USPS postage calculator or have the completed mailpiece checked at a Post Office.

Why Stamp Prices Change

USPS periodically changes mailing prices. A rate change can affect one category without changing every other category by the same amount. For example, the one-ounce stamped-letter price rose to $0.82 on July 12, 2026, while the additional-ounce amount remained $0.29.

Older year-specific searches may show a price that was correct at the time but is no longer current. Always check the effective date before relying on a number. Forever-category stamps continue to follow the applicable category identified on the stamp under USPS rules.
