The current value of a Forever Stamp is the one-ounce First-Class Mail price set by the U.S. Postal Service. As of the most recent price change, that domestic rate is $0.66 for a single Forever Stamp used on a standard letter up to one ounce. A Forever Stamp remains valid for first-class mail no matter how prices rise in the future, making it a predictable option for standard-weight correspondence within the United States. This guide explains how Forever pricing works, when and why the value changes, and how to use stamps effectively when mailing domestically and internationally.
How Forever Stamp Pricing Works
Forever Stamps are sold at the current First-Class Mail price for a one-ounce letter. Once purchased, they can be used to mail a one-ounce letter regardless of future price increases. The value is tied to the published price for one ounce; if you need to send heavier mail, additional postage is required. Understanding this helps you plan for predictable costs when sending standard letters and avoid last-minute surprises at the post office.
The Mechanism: Locking In Today’s Rate
- Buy at today’s first-class price; use forever at any future rate for one ounce.
- Issued by an official postal authority and accepted for First-Class Mail indefinitely.
- No expiration date; valid as postage as long as it remains a legitimate stamp.
Current Domestic Value and Recent Changes
As of the latest U.S. Postal Service price change, the domestic rate for a one-ounce First-Class letter is $0.66, so a Forever Stamp purchased under this pricing is worth $0.66 for standard domestic use. Historically, the rate was $0.63 in prior periods before adjustment. Price updates are typically announced in late January and implemented in early January or late July of each year. Tracking these changes helps you assess whether buying now or later makes sense for your mailing volume.

Validity and Acceptability Rules
Forever Stamps are valid for first-class mail within the United States and do not expire. The stamp value is locked at the purchase price, which covers the then-current first-class rate for up to one ounce. If postal rates increase, your Forever Stamp can still be used to send a one-ounce letter without adding extra postage. Avoid using Forever Stamps for international destinations or for heavy packages; doing so will result in insufficient postage and possible delays.
International and Heavy Mail Considerations
- Not valid for international shipments; use International Forever or additional postage.
- For letters over one ounce, calculate exact weight and add extra postage accordingly.
- Stamps purchased at domestic rates cannot cover non-mailing services or customs forms.
Using Multiple Stamps and Calculating Postage
When a letter exceeds one ounce, you can combine one Forever Stamp with additional postage to cover the full weight. For example, a letter weighing two ounces requires $1.32 in total; you can pair one Forever Stamp at the current rate with extra stamps or metered postage for the remaining ounce. Use the USPS online calculator or consult a rate chart to determine the precise amount needed based on weight and destination. This approach ensures you meet exact postage requirements without overpaying.
Practical Tips and Common Questions
Buying Forever Stamps can be cost-effective when you anticipate rate increases, but they offer no monetary investment value; they are simply a convenience tool. Always check the current first-class rate before purchasing in bulk and confirm that your mail weighs no more than one ounce if using only a single Forever Stamp. Keep unused stamps in a safe, dry place; they remain valid indefinitely. Remember that Forever Stamps are for domestic first-class letters only and must be supplemented for international or heavier items. Tracking the official USPS price calendar helps you time purchases to maximize value.
