The current price of a US first-class stamp is determined by the United States Postal Service (USPS) and is subject to periodic adjustments. As of the most recent update in 2024, a single first-class Forever Stamp is priced at $0.66 for a 1-ounce letter mailed domestically. Additional ounce increments carry specific, published charges. Rates vary by destination, mail shape or size, and service type, with Priority Mail, Priority Mail Express, and Retail Ground each having distinct price points. This guide clarifies pricing structures, where to verify live rates, and how to choose the right option for your mailing needs.
How the Current Price of US Stamps Is Determined
Postage prices are set by the USPS based on service level, weight, dimensions, and delivery speed. The primary cost metric is the First-Class Mail price for a 1-ounce letter, which anchors the Forever Stamp value. Heavier letters, larger envelopes, and parcels are priced using zone-based or distance-independent models depending on the service. Retail prices apply to individual customers, while commercial and bulk customers may qualify for volume discounts and presorted rates. The official source for current pricing is the USPS Price Calculator or the USPS retail price list.
Key Pricing Factors
- Weight: Measured in ounces for letters and first-class items; pounds for larger parcels.
- Dimensions: Flats (large envelopes) and packages have different rate tables than letters.
- Service Level: First-Class, Priority, Express, and Retail Ground each have distinct price points.
- Distance: Some services, like Priority Mail, use zones for domestic rates.
- Delivery Speed: Faster services, such as Priority Mail Express, cost more.

How to Find the Current Price for Your Mail
To determine the exact price for your item, start with the USPS tools and verify the latest rates. Prices change periodically, and using outdated information can lead to underpayment or delays. The most accurate and current approach is to use official USPS channels and understand what influences the final cost.
Practical Steps to Check Pricing
- Visit the USPS Retail Price List or use the online Price Calculator.
- Enter the item’s weight, dimensions, origin and destination ZIP codes, and service type.

- Purchase stamps or labels at a Post Office, via USPS.com, or through approved vendors.
Types of US Stamps and Their Uses
