What Are Forever Stamps, and When Do They Actually Save You Money?
Share
A Forever stamp is a First-Class Mail stamp that always covers a standard 1-ounce letter, no matter when you bought it or how many times postage rates have gone up since. So if you're wondering what are Forever stamps good for, the short version is: you buy them once, and they never expire or lose value. Below, we'll walk through how they work, when a single stamp isn't enough, and whether stockpiling them before a rate hike is actually smart or just a habit.
What Is a Forever Stamp?
A Forever stamp is a nondenominated postage stamp from the United States Postal Service that pays for one ounce of domestic First-Class Mail forever. It carries no printed cent value. Buy it at today's price, use it in ten years after three rate increases, and it still mails your letter. No extra postage needed.
The USPS launched the first Forever stamp on April 12, 2007 (source: USPS History). Back then a stamp cost 41 cents. The idea was simple: stop making people scramble for 1-cent and 2-cent stamps every time rates crept up.
That's the whole appeal. You're locking in the service, not the price.
How Forever Stamps Work
Two things happen once a Forever stamp is in your drawer.
First, it never expires. There's no date stamped on it and no window where it stops being valid. Second, its value floats. When the USPS raises the one-ounce rate, every Forever stamp you already own quietly rises to match the new rate. You paid 68 cents last year? That same stamp now covers a 78-cent letter. You keep the difference.
Here's where people get tripped up. A Forever stamp covers one ounce of First-Class Mail. That's it. It doesn't magically pay for a two-ounce letter, a bulky greeting card, or a package. Weight and shape still matter, which we'll get to.
If you're buying in quantity for a small business or a wedding mailing, a run of usps stamps in the Forever format saves you from re-pricing every envelope the next time rates change.
Forever vs. Regular Stamps
This is the top question people ask, so let's answer it head-on.
| Forever stamp | Regular denominated stamp | |
|---|---|---|
| Printed value | None ("Forever") | A set amount (e.g., 68¢, 10¢) |
| Covers 1-oz letter after a rate hike? | Yes, automatically | No — you add cent stamps |
| Expires? | No | No, but only worth its face value |
| Best for | Everyday letters, stockpiling | Exact postage, collectors, odd weights |
A regular stamp is worth exactly what's printed on it, forever. A 10-cent stamp is always 10 cents of postage. Useful, but if the letter rate is 78 cents, you're doing math and stacking stamps. A Forever stamp skips all of that.
One honest caveat: denominated stamps aren't useless. If you mail odd weights often, keeping a strip of low-value stamps to top off heavier envelopes is genuinely handy. Forever stamps handle the common case; denominated stamps handle the exceptions.
Forever Stamp Price History
Competitors quote today's price and move on. We think the full run tells you more, especially if you're deciding whether to buy ahead. Here's the domestic Forever rate since launch (verify the current figure at usps.com, since rates change and the newest number may have shifted after publication):
| Effective date | Forever stamp price |
|---|---|
| Apr 2007 | 41¢ |
| May 2009 | 44¢ |
| Jan 2014 | 49¢ |
| Apr 2016 | 47¢ (a rare decrease) |
| Jan 2019 | 55¢ |
| Jul 2022 | 60¢ |
| Jan 2023 | 63¢ |
| Jul 2023 | 66¢ |
| Jan 2024 | 68¢ |
| Jul 2024 | 73¢ |
| Jul 2025 | 78¢ |
Notice the pace lately. Between 2019 and 2025 the rate jumped from 55 to 78 cents, most of it in the last three years. That acceleration is exactly why the bulk question comes up so often. For a year-by-year breakdown, our forever stamps by year reference lays out each change.
Callout — current rate as of this update (August 2026): 78¢, set July 2025. Confirm before mailing anything time-sensitive.
Buying Forever Stamps in Bulk
Does stockpiling before a rate hike actually save money? Sometimes. Let's do the arithmetic instead of guessing.
Say the rate is 78 cents and you expect a jump to 83 cents. Buy 100 stamps now and you lock in 78 cents apiece. After the increase, each of those stamps is worth 83 cents of postage. You've "saved" 5 cents per stamp — $5 across the hundred.
Is $5 worth it? For a household that mails a dozen letters a year, no. Those 100 stamps last you eight years, and you tied up cash for a rounding error. For a business or nonprofit sending hundreds of pieces a month, the same math scales into real money, and buying ahead of a scheduled increase makes sense.
The break-even is really about volume and timing, not the stamp itself. If you'll use them before they'd otherwise sit in a drawer, buying before a confirmed rate change is a small, safe win. If you're buying 500 stamps as an "investment," that's not what these are. There's no resale premium — a Forever stamp is worth exactly one letter, and Forever stamps don't expire, so there's no urgency created by aging, either.
When One Stamp Isn't Enough
A Forever stamp covers one ounce of a standard letter. Cross any of these lines and you need more:
- Over one ounce. A heavier letter needs additional postage. Two Forever stamps overpay for most two-ounce letters, so a Forever plus a small denominated stamp is cheaper.
- International mail. Domestic Forever stamps don't cover overseas letters. You need a Global Forever stamp, which pays for a one-ounce international letter to most destinations and floats with international rates the same way.
- Non-machinable mail. Square envelopes, rigid cards, or anything USPS can't run through automated sorting carries a surcharge. One Forever stamp won't cover it.
And a real-world concern the top articles skip: counterfeits. Fake Forever stamps sold at steep "discounts" online have become common enough that USPS has warned about them. If a deal looks far below face value, it usually is. Buy from the USPS, a licensed retailer, or a seller that inspects and verifies authenticity — which is exactly why we inspect every stamp we source for condition and legitimacy before it ships.
FAQ
Forever vs. regular stamps difference?
A Forever stamp always covers a 1-ounce letter, even after rate hikes. A regular stamp is worth only its printed value, so you must add cent stamps when rates rise.
Is it worth buying Forever stamps?
Yes for regular or bulk mailers, especially before a scheduled rate increase. For someone mailing a few letters a year, the savings are pennies and not worth stockpiling.
Do I need to use two Forever stamps?
Only if your letter is over one ounce or non-machinable. For a standard one-ounce letter, a single Forever stamp is always enough.
How much do 20 Forever stamps cost?
At the current 78-cent rate, 20 Forever stamps cost $15.60 at face value. Prices track the USPS one-ounce rate, so confirm the current figure before buying.
