A book of 20 Forever stamps costs $16.40 in 2026, priced at 82 cents per stamp. That answers how much is a book of stamps for most people buying at the Post Office, USPS.com, or an authorized retailer.
The price moves whenever the Forever rate changes, and it changed twice already in 2026. This guide covers the exact math and how a book compares to a roll or a sheet on price. It also covers the few places where you can pay more than face value.
How much is a book of stamps in 2026
A standard book holds 20 stamps. The price is simply the per stamp rate times 20. At the current First-Class Forever rate of 82 cents, that puts a book at $16.40.
That rate took effect July 12, 2026, up from 78 cents. A book of postcard stamps costs less, since the postcard rate sits below the letter rate. Twenty postcard stamps at 65 cents each comes to $13.00.
A book of Global Forever stamps, used for international mail, runs $35.00 at $1.75 each. Each one covers a one ounce letter or postcard to any country.
| Book type | Stamps | Price in 2026 |
|---|---|---|
| Forever (First-Class letter) | 20 | $16.40 |
| Postcard | 20 | $13.00 |
| Global Forever (international) | 20 | $35.00 |
The math behind the price
The math behind how much is a book of stamps never changes shape. Only the rate does. Multiply the per stamp price by 20 and you have the book price, with no bulk discount folded in.
USPS has raised the Forever rate twice a year in most recent cycles rather than once. So the book price you see today may not hold past the next January or July adjustment. Any book you already own keeps working at face value no matter how high the rate climbs later.
Books vs rolls vs sheets: does the format change the price
The format does not change what you pay per stamp. A roll of 100 Forever stamps costs $82.00 in 2026. That is exactly five books worth of postage, not a cent less.
A commemorative sheet of 20 also runs $16.40, the same as a plain book. The cardboard cover or the perforated sheet edge changes nothing about the price.
| Format | Stamp count | Total price in 2026 |
|---|---|---|
| Book | 20 | $16.40 |
| Roll (coil) | 100 | $82.00 |
| Sheet or pane | 20 (varies for some commemoratives) | $16.40 |
A roll only saves money if you use all 100 stamps before the rate rises again. It saves nothing per stamp otherwise. A book is the right size for most households.

Where a book of stamps costs exactly $16.40
Face value pricing is the rule at the Post Office counter, USPS.com, and kiosks inside post office lobbies. Most grocery stores, pharmacies, and big box retailers that stock Forever stamps also sell them at face value.
USPS licenses these stores as authorized vendors, so the price matches what the Post Office charges. Warehouse clubs like Costco and Sam’s Club typically match face value too, and occasionally discount rolls slightly for members.
Self service kiosks and vending style machines inside a lobby also charge face value. USPS operates or licenses those machines directly. Our guide to every place that sells stamps at face value lists the full set of legitimate retailers.
Where a book of stamps costs more than $16.40
Online postage services that print stamps on demand often add a convenience fee on top of face value. Some calculate that fee as a percentage of the order rather than a flat charge per stamp.
Real sellers on shipping forums have reported paying noticeably more this way. A physical book bought at a store usually costs less by comparison.
Third party sellers on marketplaces like Amazon or eBay sometimes mark up loose stamps or books above face value. This shows up most often with older or specialty designs.
Some gas stations and small convenience stores tack on a few cents per stamp too. That extra charge covers the convenience of skipping a post office trip. None of this changes what a book actually costs from USPS directly, only what a reseller chooses to charge.
Do commemorative and holiday books cost more
No. A commemorative design costs the same 82 cents per stamp as a plain Forever design. That holds whether it features a holiday theme or a well known figure.
Some collector editions marketed as keepsakes do carry a premium, since those are priced as memorabilia rather than usable postage. A standard commemorative book bought off the rack or from the USPS Postal Store costs the same as any other book of 20.
What determines the price you pay
Three factors decide what a book of stamps costs on any given day. Those are the current Forever rate, the book type, and whether the seller charges above face value. Our guide to what a Forever stamp actually covers explains why the design keeps its value as the rate rises.
Extra weight or an oversized envelope can push a mailing past one stamp per piece. The book price stays the same either way. You will just need more stamps per item, so check our stamp calculator first.
The bottom line
How much is a book of stamps comes down to one multiplication: 82 cents times 20. That equals $16.40 at the 2026 Forever rate. Rolls and sheets cost the same per stamp, so the format is just a matter of convenience.
Stick to the Post Office, USPS.com, or an authorized retailer and you will always pay face value. For the complete 2026 rate picture beyond just the book price, see our full 2026 stamp price breakdown.
