Additional Questions and Answers about Postage Stamps and Rates

What is a Forever Stamp?

Forever Stamps are a special type of stamp created by the United States Post Office that will always be worth one First Class stamp. When they were initially created in 2007 a Forever Stamp cost only $0.41. Their value has increased since then and they are now worth significantly more. Remember how you used to have buy $0.01 or $0.02 stamps to cover postage cost increases? That is a thing of the past with Forever Stamps!

How much is a First Class Stamp?

The cost of a first class stamp varies, with the price being adjusted (typically once every year or so) by the Post Office. The current rate is $0.49 (see above for historical values). By purchasing a "Forever Stamp", the stamp's value will adjust to match whatever the then-current postage rate is for a one ounce stamp.

Does the Post Office Have an Online Postage Calculator?

Yes, they do. It's available here: USPS Postage Price Calculator. Around May of 2017 the calculator was updated to make it easier to use, but, WOW, for calculating postage for letters/envelopes it became MUCH more difficult to use. And, yes, what do you expect? It's a government-created web site :-) All kidding aside, it works quite well for Priority mail and packages. If you are looking up the price for a letter, on the first screen, make sure you select the icon titlted "Calculate price based on Shape and Size".

How much does it cost to mail a postcard?

In 2017 the cost to mail a standard size postcard is 34 cents ($0.34). The postcard can be no larger than 6 inches by 4.25 inches.

Was the United States the first to issue Forever Stamps?

Forever Stamps are a type of "non-denominated postage". While I do not know for sure which country was first, I do know that the United Kingdom began issuing non-denominated postage stamps back in 1989. The United States Postal Service launched "Forever Stamps" in 2007. In addition, the USPS had been issuing generic stamps close to rate changes that could be used before and after the rate change starting back in the 1970's. The practice continued in more recent years with stamps that began with a letter: A, B, or C, and continued up through the letter H.

How much do additional ounces cost when mailing a letter?

In 2017 the cost for each additional ounce of postage is 21 cents ($0.21).

Where is the best place to buy postage?

You have quite a few options for puchasing postage online. The obvious option is to buy stamps directly from the Post Office. They do charge $1 for shipping/handling your order.

Another option (which helps support this site) is to sign up for an account at You can get a special postage offer with a $100 value by using code COUPON1.

 You can also buy stamps from (which helps support this site). The Post Office is actually one of the stamp sellers at If you buy stamps at you will likely pay a little bit more than if you bought them directly from the post office, but if you are a member of Amazon Prime (free trial available), you won't have to pay the $1 shipping and handling fee that the Post Office charges if you order directly from the USPS.
