Buying stamps seems simple until you actually need them. Many people search for the price of a book of stamps because they are standing at the post office, preparing invitations, sending important documents, or trying to plan their mailing budget.

One of the most common frustrations is that USPS postage prices change over time. A stamp book that cost less a few years ago may have a completely different price today, which makes it difficult to know what you should expect to pay.

Another common question is whether older Forever Stamps are still valid or if buying stamps before a price increase can actually save money. These questions matter because even a small difference in postage costs can add up when you mail cards, business letters, or multiple documents throughout the year.

In this guide, we break down the current cost of a book of USPS Forever Stamps, explain how many stamps come in a booklet, show where to buy them, and share practical tips to help you avoid overpaying.

Whether you mail occasionally or manage regular business correspondence, understanding how stamp books work can help you make smarter mailing decisions.

Quick Answer: How Much Is a Book of Stamps?

A standard book of USPS Forever Stamps contains 20 stamps, and the total price simply depends on the current cost of a single Forever Stamp.

To calculate the cost of a stamp book, use this formula:

Book of Stamps Price = Single Forever Stamp Price × 20

For example, if one Forever Stamp costs $0.82, a book of 20 stamps costs $16.40.

Forever Stamps are popular precisely because they remain valid even after USPS increases postage prices, which means stamps you buy today can still be used down the line for eligible First-Class Mail letters.

What is a Book of Stamps and How Many Stamps in a Book?

A book of stamps is a small booklet containing multiple postage stamps, and it’s the most common way people buy stamps in the United States. Rather than purchasing stamps one at a time, you can buy an entire booklet and keep it at home, in your office, or tucked in your wallet whenever you need to mail a letter.

Today, a standard USPS stamp book contains 20 Forever Stamps, and each one pays for mailing a standard one-ounce First-Class Mail letter anywhere in the United States.

According to the United States Postal Service (USPS), Forever Stamps are non-denominated stamps that remain valid for the current First-Class Mail one-ounce letter rate, even if postage prices increase after purchase. This makes them a genuinely useful option for anyone who wants to purchase postage in advance.

Who Usually Buys a Book of Stamps?

A book of stamps is useful for many different types of mail users, and the right quantity really depends on how often you mail and what kind of items you typically send.

Common buyers include:

• Families sending personal cards and letters
• Small businesses mailing documents
• Event planners sending invitations
• Organizations sending announcements
• Collectors interested in USPS designs

Note: In most small offices, keeping postage stocked falls to whoever handles office supplies and business correspondence; a routine but genuinely valuable administrative duty.

What Is the Difference Between a Stamp Booklet, Sheet, and Coil?

USPS sells stamps in a few different formats to match different mailing needs, though the postage value of each Forever Stamp stays the same no matter which format you choose.

A stamp booklet is the most common option for households, usually containing 20 Forever Stamps in a small, folded package that’s easy to store. A stamp sheet, on the other hand, arranges stamps on a flat page and tends to be popular with collectors and people who like keeping their stamps organized. A stamp coil or roll connects stamps in a continuous strip, and businesses or frequent mail users often prefer this format because it’s faster to use when sending large volumes of mail.

Stamp Format	Typical Quantity	Best For
Booklet	20 stamps	Home users and occasional mail
Sheet	20 stamps	Collectors and organized storage
Coil/Roll	100+ stamps	Businesses and frequent mailing

What Is a Forever Stamp?

A Forever Stamp is a postage stamp issued by the United States Postal Service (USPS) that always keeps its value for First-Class Mail, even after postage prices increase.

For example, if you bought Forever Stamps back when they cost 60 cents, you can still use them today even though the current rate is 82 cents, with no need to add extra postage for a standard one-ounce letter.

This built-in protection makes Forever Stamps a smart choice for anyone who mails letters regularly throughout the year.

Why Does a Book Contain 20 Stamps?

Many people wonder why USPS sells books with 20 stamps instead of 10 or 25, and the answer comes down to convenience.

A booklet of 20 stamps strikes a good balance between practicality and value, giving most households enough postage for several weeks or months without needing to buy a large roll. Businesses and organizations that mail large volumes often opt for coils or rolls containing 100 or more stamps instead, while everyday customers tend to prefer the standard book simply because it’s easy to carry and store.

What Can You Mail With a Forever Stamp?

One Forever Stamp covers postage for:

• A standard First-Class Mail letter
• Up to one ounce in weight
• Mail sent anywhere within the United States

If your letter weighs more than one ounce, has unusual dimensions, or requires extra services, you’ll likely need additional postage on top of the Forever Stamp.

How Many Stamps Do You Need for a Letter?

The number of stamps you need depends on the weight, size, and destination of your mail, so it’s worth checking your envelope before you seal it.

For a standard domestic First-Class Mail letter:

• A one-ounce letter usually requires one Forever Stamp.
• Heavier letters may require additional postage.
• Large envelopes may have different postage rates.
• International letters require Global Forever Stamps or other international postage options.

Why Do People Buy Books of Stamps?

Buying a book of stamps is simple and convenient, and it also helps you prepare for future postage increases since Forever Stamps hold onto their mailing value no matter what happens to prices later.

Many people buy stamp books for:

• Sending greeting cards
• Paying bills by mail
• Mailing legal documents
• Shipping personal letters
• Small business correspondence
• Holiday cards and invitations

Keeping a book of stamps at home means you always have postage ready the moment you need it, and understanding what a book of stamps includes helps you choose the right postage option and avoid extra trips to the post office.

Current Cost of Stamps in 2026

As of July 2026, a single USPS Forever Stamp costs $0.82, and since a standard book contains 20 Forever Stamps, the current price of a book of stamps comes out to $16.40.

This price applies to standard Forever Stamps used to mail a one-ounce First-Class Mail letter anywhere in the United States.

Forever Stamp Book Price = Current Forever Stamp Price × 20

Because Forever Stamps hold their value after price increases, many households and businesses choose to buy them before USPS rate changes take effect. Here’s a quick look at the current prices.

USPS Stamp Product	Quantity	Current Price
Single Forever Stamp	1	$0.82
Book of Forever Stamps	20	$16.40
Sheet of Forever Stamps	20	$16.40
Coil of Forever Stamps	100	$82.00

The price of a book of stamps is easy to calculate using this formula:

Book Price = Price of One Forever Stamp × Number of Stamps

$0.82 × 20 = $16.40

This same formula helps you estimate the cost of larger quantities as well:

• 10 Forever Stamps cost $8.20.
• 20 Forever Stamps cost $16.40.
• 50 Forever Stamps cost $41.00.
• 100 Forever Stamps cost $82.00.

Keep in mind that these prices apply to Forever Stamps only, since USPS also sells other types of postage at different prices, including:

• Global Forever Stamps
• Postcard Stamps
• Additional Ounce Stamps
• Extra Services, such as Certified Mail and Registered Mail

If you’re mailing a heavy letter, a large envelope, or an international package, you’ll likely need to pay more than the standard Forever Stamp rate.

What Are Global Forever Stamps?

Global Forever Stamps are designed specifically for international mail, allowing customers to send eligible one-ounce letters outside the United States. These stamps carry a different price from domestic Forever Stamps because international mail involves additional transportation and processing costs.

If you frequently send letters abroad, Global Forever Stamps may be a better choice than regular domestic stamps.

Does Every Book of Stamps Cost the Same?

Yes. A standard book of 20 USPS Forever Stamps costs the same no matter where you buy it, as long as you’re purchasing from an authorized seller.

You can buy stamp books from:

• USPS Post Offices
• The USPS online store
• Grocery stores
• Walmart
• CVS Pharmacy
• Walgreens
• Office supply stores
• Warehouse clubs, such as Costco

Some warehouse clubs may occasionally offer a small discount on stamp books, though most retailers stick to the official USPS price.

Are There Different Types of Stamp Books?

Yes. USPS regularly releases new stamp designs throughout the year, so you’ll find plenty of variety even though the mailing value stays consistent across every design.

You may find themes featuring:

• American flags
• Flowers
• Wildlife
• Holidays
• Historical figures
• Seasonal artwork
• Commemorative events

Although the artwork changes, every Forever Stamp in a standard book can still be used to mail an eligible one-ounce First-Class Mail letter, which means you can pick the design you like best without paying a different price.

Why Do Forever Stamp Prices Change?

USPS adjusts postage prices because running a nationwide delivery network requires significant, ongoing resources.

Several factors influence postage rates, including:

• Inflation
• Employee wages and benefits
• Fuel and transportation costs
• Mail volume changes
• Equipment and operational expenses

Inflation has pushed up the cost of nearly every household essential over the same period, which is part of why grocery staples like beef cost more than they did a few years ago.

USPS postage changes are reviewed under federal regulations before any new rates become effective.

USPS Postage and Forever Stamp Price Over Time

The cost of mailing a letter has crept upward over the years, much like many other everyday products and services, as postage prices adjust to help cover operating costs and keep the postal network running smoothly.

One of the biggest advantages of Forever Stamps is that they shield you from these price increases entirely. If you buy Forever Stamps before USPS raises its rates, you can keep using them later without paying the difference for a standard one-ounce First-Class Mail letter.

Forever Stamp Price History

The table below shows how the price of a Forever Stamp has changed since it was first introduced.

Year	Forever Stamp Price	Cost of a Book of 20
2007	$0.41	$8.20
2009	$0.44	$8.80
2012	$0.45	$9.00
2013	$0.46	$9.20
2014	$0.49	$9.80
2016	$0.47	$9.40
2017	$0.49	$9.80
2018	$0.50	$10.00
2019	$0.55	$11.00
2021	$0.58	$11.60
2022	$0.60	$12.00
2023	$0.66	$13.20
2024	$0.68	$13.60
2025	$0.73	$14.60
2026	$0.82	$16.40

The overall trend is clear: stamp prices have gradually climbed over time, which is exactly what makes Forever Stamps such a smart purchase for anyone who mails letters on a regular basis.

Why Does USPS Increase Stamp Prices?

Several interconnected factors affect the cost of postage over time.

Reason	How It Affects Prices
Inflation	Higher operating costs
Labor	Employee wages and benefits
Transportation	Fuel and delivery expenses
Lower mail volume	Less revenue from letters
Regulations	USPS rate approval process

Should You Buy Forever Stamps Before Prices Increase?

In many cases, yes, buying Forever Stamps ahead of a scheduled rate increase can genuinely save you money over time.

For example, if you purchase a book of 20 stamps at $16.40 today and USPS raises the Forever Stamp price next year, your existing stamps will still cover the full postage for eligible one-ounce First-Class Mail letters. This is one of the biggest reasons many households and small businesses like to keep extra books of Forever Stamps on hand, since it lets you keep mailing letters without ever paying additional postage for standard First-Class Mail.

Where to Buy a Book of Stamps Online or In Person

Buying a book of stamps is simple because USPS Forever Stamps are available through many trusted sources. You can purchase them directly from USPS, order them online, or find them at common retail locations.

The best option depends on whether you want the largest selection, fastest purchase, home delivery, or possible savings.

USPS Post Office

The USPS Post Office is the official place to buy Forever Stamps. Local post offices usually offer the widest selection of stamp designs, including standard Forever Stamps, seasonal releases, and commemorative collections.

Buying from USPS is a good option if you also need other mailing services, such as sending packages, purchasing envelopes, or getting help with postage requirements.

Best for:

• People who want the newest stamp designs
• Customers who need mailing assistance
• Those who prefer buying directly from USPS

USPS Online Store

You can also buy stamp books online through the official USPS website. This option allows you to browse available stamp designs, place an order, and receive stamps directly at your home.

Buying stamps online is convenient for people who prefer avoiding trips to the post office or want to purchase stamps in advance.

Many retail stores sell USPS Forever Stamp books, making it easy to purchase stamps while completing other errands.

Common locations include:

• Grocery stores
• Pharmacies such as CVS and Walgreens
• Walmart
• Target
• Office supply stores such as Office Depot and Staples

Availability can vary by location, so it is a good idea to check with the customer service desk if you do not see stamps available.

Best for:

• Quick purchases
• Everyday mail users

Warehouse Clubs

Warehouse clubs can be another option for people who buy stamps regularly.

The right choice depends on mailing volume and how often postage is needed.

How to Save on Stamps

Although postage prices are fixed in most places, there are still several practical ways to reduce your mailing costs over time.

Buy Larger Quantities

If you mail letters regularly, consider purchasing several books or a coil of 100 Forever Stamps at once. Buying larger quantities cuts down on the number of shopping trips you need to make and ensures you always have postage on hand when you need it.

Can Buying Stamps in Bulk Save Money?

Buying stamps in bulk doesn’t usually reduce the price per Forever Stamp, since a booklet, sheet, or coil normally carries the same value per stamp. However, buying larger quantities can still help because it allows you to:

• Avoid last-minute purchases
• Keep postage available at home
• Buy before future price increases
• Reduce trips to purchase stamps

Businesses that mail frequently may benefit even more from online postage tools or commercial mailing services.

Watch for Warehouse Club Discounts

Warehouse clubs such as Costco occasionally sell stamp books at a slightly lower price than many retail stores. The discount is usually small, but frequent mailers may notice meaningful savings over time, so it’s always worth comparing prices before buying in bulk.

Avoid Last-Minute Purchases

Running out of stamps often means an extra trip to the store. Keeping one or two unopened books at home saves time, helps you avoid unnecessary travel, and prepares you for future postage increases.

Use Online Bill Pay

Many banks and service providers offer free online bill payment, and paying bills electronically reduces the number of letters you need to mail,  which can meaningfully lower your yearly spending on stamps.

Switch to Digital Invitations When Appropriate

If you regularly send invitations, reminders, or announcements, consider switching to email or digital invitation services when printed mail isn’t strictly required, since digital communication eliminates postage costs completely. That said, printed invitations remain a popular choice for weddings, baby showers, birthdays, and other special occasions.

Print Postage from Home

If you own a small business or frequently ship packages, online postage services can save both time and money. Many platforms allow you to:

• Print postage labels
• Schedule USPS pickups
• Compare mailing services
• Access commercial shipping rates

This helps cut down on trips to the post office while simplifying your overall mailing process.

Compare Your Mailing Needs

Not every mailing requires the same type of postage, so before buying stamps, it helps to ask yourself:

• Am I mailing letters or packages?
• How often do I send mail?
• Do I need domestic or international postage?
• Would a coil of stamps be more practical?

Choosing the right postage option upfront helps you avoid buying more stamps than you actually need.

Quick Tips to Save Money on Stamps

• Buy Forever Stamps before USPS announces higher rates.
• Keep extra stamp books at home.
• Look for occasional warehouse club discounts.
• Use online bill payment when possible.
• Print postage at home if you ship regularly.
• Purchase only the quantity you expect to use.

A little planning can go a long way toward lowering your mailing costs throughout the year while making sure you always have the right postage on hand.

Why Knowing the Cost of a Book of Stamps Matters 

The cost of a book of stamps may seem small at first glance, but postage expenses can add up considerably over time. Families, students, nonprofits, and businesses all rely on stamps for different reasons, and understanding current USPS stamp prices helps you plan your budget and avoid unexpected costs, especially if you know when to buy stamps before the next rate increase.

For Personal Mail

Many people still use traditional mail for important occasions and everyday tasks, including:

• Birthday cards
• Holiday cards
• Wedding invitations
• Baby shower invitations
• Thank-you cards
• Personal letters
• Utility payments
• Government forms

Buying a book of 20 Forever Stamps means you always have postage ready when you need it, so instead of making repeated trips to the store, you can simply keep a supply at home.

For Nonprofit Organizations

Nonprofits often send newsletters, fundraising appeals, donation receipts, and event invitations through the mail, and even a small increase in postage can affect a mailing budget. Planning ahead and buying Forever Stamps before rate increases take effect can help reduce future mailing costs.

For Schools and Colleges

Schools and educational institutions still rely on traditional mail for many purposes, including:

• Admission letters
• Certificates
• Official notices
• Parent communications
• Graduation announcements

Keeping an adequate supply of stamps on hand helps schools avoid delays when important documents need to go out.

Books, Sheets, and Rolls Cost the Same Per Stamp

Some people assume buying a larger quantity lowers the price per stamp, but for USPS Forever Stamps, the cost per stamp generally stays the same across formats. Here’s a simple comparison.

Product	Number of Stamps	Total Cost	Cost Per Stamp
Single Stamp	1	$0.82	$0.82
Book	20	$16.40	$0.82
Sheet	20	$16.40	$0.82
Coil	100	$82.00	$0.82

The main difference really comes down to convenience, people who mail frequently often prefer rolls, while most households find a book of 20 stamps more practical for everyday use.
