Compiled by Radif Partners · How the prices are built
A book of stamps is a booklet of 20 Forever stamps, and its cost is 20 times the First-Class Mail price of a 1-ounce letter. With a Forever stamp at $0.82 in the Notice 123 price list read on November 13, 2026, a booklet of 20 costs $16.40. The same 20 stamps also come as a pane, or sheet, at the same total. Coils of 100 cost $82.00, and larger coils of 3,000 and 10,000 exist for businesses; these formats are listed for the U.S. Flag Forever stamp issued on June 9, 2026 in the Postal Bulletin. The price of a book changes only when the letter price changes: it was $15.60 after the July 13, 2025 change, when a stamp was 78 cents, and has been $16.40 since July 12, 2026. The Postal Service filing for January 2027 makes no change to stamp prices, so a book bought today still costs $16.40 after January 17.

Making a book of stamps last
Weigh before you stick: a standard envelope with a few sheets of paper weighs about an ounce and takes one stamp, while a thick card or a square envelope needs more postage. The stamps calculator counts them. Stamps you already hold keep their full value after a change, which the Forever stamp page works out for any purchase date. Keep booklets flat and dry so the self-adhesive stamps peel off cleanly when you need them.
