Any article that answers "how much is a stamp" with a number is wrong within a year or two. Rates move. What does not move is the structure underneath them — and once you know that, you can work out the price of anything you are mailing without looking up a table.
What actually sets the price
Three things, in this order.
Class of service. A letter, a postcard, a large envelope and a package are four different products with four different price ladders. Getting this wrong is the expensive mistake, because a piece that crosses from letter into large-envelope territory does not cost a little more — it jumps to a different ladder entirely.
Weight. Priced in ounces, with the first ounce costing the most and each additional ounce adding a smaller fixed amount. A two-ounce letter is not double a one-ounce letter.
Shape. Anything that cannot run through automated sorting equipment carries a surcharge on top of the weight-based price. Square envelopes, rigid enclosures, unusual thickness, clasps. This is a separate charge, not extra weight, and it is where wedding stationery and greeting cards routinely go wrong.
Notice what is absent: distance. Domestic letter postage does not vary by how far the letter travels.
Where to look up today's number
The USPS site publishes current retail prices, and its calculator will price a specific piece if you give it the weight and dimensions. That is the only source worth trusting — a rate quoted in a blog post, including this one, is a snapshot of whenever it was written.
The reliable habit is to weigh one assembled piece and price that, rather than estimating from a table.
Which is where Forever stamps come in
A Forever stamp carries no printed value. It pays for a one-ounce First-Class letter at whatever the rate is on the day you use it, no matter what you paid.
That is what makes the "how much is a stamp" question awkward to answer. A Forever stamp bought several rate increases ago cost less than one bought today, and both mail the same letter. The price you paid and the postage you get are two different numbers, permanently decoupled.
The practical consequence: stocking up ahead of an increase is a real saving, and there is no downside, because the stamps do not expire.
How they are sold
Singly — at a counter, usually when you need one for something specific.
In books — the standard retail unit, a folded booklet of twenty. What most households buy.
In coils and rolls — long strips wound on a core, from a hundred up into the thousands. For anyone mailing in quantity, and the only format that suits a stamp affixer.
In sheets and panes — how commemoratives are sold, and how collectors prefer to keep them, because a full pane with its margins is worth more intact than cut up.
Price per stamp is the same across these formats at the post office. The saving on volume, where it exists at all, is on the resale side.
The other kind of value
Stamps have a second price that has nothing to do with postage. A design that is scarce, in good condition, and wanted by collectors can be worth a great deal more than its face value — and a design that printed in the hundreds of millions will never be worth more than what it will mail.
Both prices are real, and they behave in opposite directions. Postage value rises automatically with every rate increase and applies to every valid stamp. Collector value depends on scarcity and condition, and applies to almost none of them.
Worth being clear about this, because a lot of buying goes wrong here. Ordinary modern stamps are postage. Treat them as postage, buy them for what they will mail, and any collector interest is a bonus rather than the plan.
Best deals on Forever stamps
Since the post office sells at face value and never discounts postage, the only place a Forever stamp costs less than its postal worth is the resale market — retired designs and surplus stock from sellers who can account for where it came from. That is the whole opportunity, and it is a modest, honest one.
Where to buy
Current prices and current issues from USPS. Retired designs below face value from a verified surplus channel such as Forever Stamp Center — see the Forever range.
The short version
Class, then weight, then shape — and never distance. Look the current number up rather than trusting one written down. Forever stamps decouple what you paid from what you get, which is why the question has no fixed answer.
