What Is the Cost of a First Class Mail Stamp?

First Class Mail letters usually include general correspondence such as credit card statements or billing invoices and typically weigh one ounce or less. These types of mail require a First Class Mail stamp.

These postage stamps cost $0.60 for a one-ounce First Class Mail when bought at the post office and $0.57 when you buy them online from This website is an independent stamp retailer licensed by the United States Postal Service (USPS).

How Do First Class Stamps Work?

First Class stamps, also called Forever stamps, are non-denominational postage. This classification means you can use these stamps to mail First Class letters regardless of the postal rate.

The USPS First Class Mail service is an affordable and convenient way to send envelopes and lightweight packages. You can mail such correspondence in one to five days or small packages in two to three days.

As of July 2022, you can choose from 71 different stamp designs for First Class Mail from the USPS website. These stamps have various themes, including sports, history, animals, science, landscapes, and holidays. Shippers can also buy these stamps at the post office.

Forever Stamps are ideal for individuals who must mail regular-sized, one-ounce letters within the United States.

If you think your letter weighs more than an ounce, consider weighing your mail before affixing a Forever stamp to it. USPS returns heavier letters that lack postage back to the shipper.

Any domestic mail piece weighing more than one ounce requires you to include additional postage with your Forever stamp to ensure that the USPS delivers that mail.

For heavier postage, you can purchase higher denomination postage stamps at the post office.

Why Do You Have First Class Stamps?

First Class stamps make up a good part of the USPS’ revenue. With postage prices tied to inflation, the USPS can request postage rate increases whenever inflation rises.

To save on postage costs, some shippers buy Forever stamps in advance, meaning you can use old Forever stamps to send First Class Mail today, even when the rates go up.

Does this cost-saving method negatively affect stamp vendors? Not necessarily. Selling newer and pricier Forever stamps allows USPS to offset operating expenses related to collecting and destroying outdated stamps whenever the postage rate increases.

This situation can benefit the shipper and the post office since both parties can save on expenses.

How Many First Class Stamps Do You Need?

You have several factors to consider when determining the number of stamps required to mail a letter. There are also varying conditions where the shipper may need to use more than one stamp.

These factors include the following:

  • The service class the shipper chooses, such as First Class, registered mail, or certified mail
  • The size of the letter
  • The weight of the letter
  • The value of the stamps

Considering these factors, the required domestic Forever stamps when sending First Class Mail weighing under 3.5 ounces are the following:

  • A one-ounce letter: One domestic Forever stamp
  • A two-ounce letter: One domestic Forever stamp and one additional ounce stamp
  • A three-ounce letter: One domestic Forever stamp and two additional 20-cent stamps
  • A 3.5-ounce letter: One domestic Forever stamp, one postcard stamp, and one 10-cent stamp

When mailing flats or large envelopes, you may need to purchase a combination of Forever stamps, domestic postcard stamps, and regular stamps, depending on your choice of cost savings or convenience.

Can You Use Two First Class Stamps for Extra Postage?

When your mail weighs more than one ounce, the post office allows you to use two First Class or Forever stamps.

However, paying for two of these stamps for mailing heavier mail pieces can be more expensive than combining one First Class stamp with other stamp types.

Forever stamps cost $0.60 for a one-ounce mail. Meanwhile, additional ounce stamps cost only $0.24 per extra ounce.

So, instead of paying $1.20 for two Forever stamps for a two-ounce letter ($0.60 x 2 = $1.20), you can purchase a Forever stamp and an additional ounce stamp for $0.84 only ($0.60 + $0.24 = $0.84).

Info on the USPS Postage Rate Increase

An April 2022 report from Washington, D.C., mentioned that the USPS filed a notice to the Postal Regulatory Commission (PRC). The organization seeks a postage price increase that takes effect July 10, 2022.

Once implemented, the new prices will include a two-cent increase for a First-Class Mail Forever stamp from $0.58 to $0.60.

The proposed price hike, approved by the U.S. Postal Service governors, will raise First-Class Mail prices by approximately 6.5%. This rate is lower than the Bureau of Labor Statistics (BLS) annual inflation rate of 7.9% as of February 2022.

This price change reflects a practical implementation of the postal service’s pricing authority provided by the PRC.
