A standard USPS First‑Class Mail Forever postage stamp currently costs 78 cents in the United States, and that rate covers a 1‑ounce letter.

Quick Scoop: How Much Is a Postage Stamp?

  • Current price of a Forever stamp (1‑oz First‑Class letter): $0.78.
  • This 78¢ rate has been in effect since July 2025 and continues into early 2026, with no additional increase scheduled for January 2026.
  • The same Forever stamp will still cover a basic 1‑ounce letter even if stamp prices go up in the future; that is the whole point of the “Forever” label.

A Bit More Detail

  • A Forever stamp is meant for a standard, 1‑ounce, rectangular First‑Class Mail letter within the U.S.
  • If your letter is heavier than 1 ounce, oddly shaped, or non‑machinable (e.g., square envelopes or lumpy contents), you need extra postage beyond that single stamp.
  • USPS has signaled another price increase might come in mid‑2026, but no exact new stamp price is published yet.

Mini Examples

  • Mailing a simple birthday card that weighs 1 ounce or less: one Forever stamp (78¢) is enough.
  • Sending a thicker letter at 2–3 ounces: you would use the 78¢ base plus extra‑ounce postage, which is priced separately per additional ounce.

TL;DR: If you walk into a U.S. post office today asking “how much is a postage stamp?”, the answer for a basic letter is 78 cents for a Forever stamp.
