Sending mail, though less common today, still requires understanding postage to ensure successful delivery. The USPS introduced Forever Stamps in 2007, simplifying postage calculation. One Forever Stamp covers the cost of a 1-ounce letter through First Class mail. For larger envelopes and packages, additional stamps are needed. Let’s explore how to calculate postage and make the mailing process hassle-free.

## How Many Stamps Per Ounce for First Class Mail?

For a standard letter via USPS First Class mail, use a Forever Stamp or a First Class mail stamp. A single Forever Stamp covers the postage, regardless of current rates, making it convenient. One Forever Stamp allows you to send a 1-ounce letter anywhere in the US. Beyond 1 ounce, additional stamps are necessary.

## Easy Rules for Calculating Postage

The number of stamps required depends on the envelope type, size, and content weight. A Forever Stamp covers the initial ounce, and for each additional ounce, the postage increases by $0.20. To avoid underpaying, either use fractional stamps or add extra Forever Stamps. Forever Stamps provide flexibility and are accepted for any future postage rate changes.

## Using Forever Stamps to Cover First Class Postage

Forever Stamps were introduced by the USPS in 2007 to replace traditional First Class stamps with denominations. Forever Stamps are nondenominational, never expire, and cover First Class postage regardless of future price increases. Today, the majority of stamps sold are Forever Stamps. They can be purchased at post offices, online, or in retail stores.

## How Many Forever Stamps Per Ounce?

Forever Stamps are great for single-ounce letters, but for heavier mail, extra postage is needed. Each additional ounce costs $0.20 (as of 2021), while a Forever Stamp costs $0.55. Using a second Forever Stamp when only 2.5 extra ounces are added may result in overpaying. However, many prefer using Forever Stamps to simplify the process.

## Weighing Your Mail to Figure Out Postage

For most standard-sized envelopes, a single Forever Stamp covers postage. However, weighing the envelope can help ensure accurate postage, especially for heavier items. Kitchen scales can provide precise weight measurements. If the weight exceeds an ounce, additional postage, either with fractional stamps or extra Forever Stamps, is needed.

## How Many Stamps Will I Need for Larger Envelopes?

While postage stamps can cover shipping costs for larger envelopes or small packages, they may not be sufficient for expensive shipments. For instance, six Forever Stamps can cover a three-dollar First Class delivery. But for higher costs, stamps alone may not be enough. For such cases, using other shipping methods may be necessary.

## The Easiest Way to Know How Many Stamps You’ll Need

To avoid any confusion, visiting the post office is the best option to determine the exact number of stamps needed for your letter. USPS employees can weigh your mail, calculate the postage, and provide the correct amount of stamps for successful delivery.
