The cost of a US first class stamp determines how much you pay to mail letters and small flats via the United States Postal Service. Prices adjust periodically, so knowing the latest rate helps you budget and avoid checkout surprises.
Below is a quick reference that highlights the current pricing and related mailing options you can choose from.
| Mail Type | Current Price (2024) | Included Weight | Delivery Timeframe |
|---|---|---|---|
| First Class Letter (1 oz) | $0.66 | 1 oz | 1–3 business days |
| First Class Large Envelope (1 oz) | $0.66 | 1 oz | 1–3 business days |
| Postcard (non-machinable) | $0.66 | N/A | 1–3 business days |
| Additional Ounce (each) | $0.24 | Per ounce | Same delivery window |
Current Pricing and Rate Changes
USPS updates rates annually, usually in January and sometimes in July. These changes reflect inflation, processing costs, and operational adjustments. For the most accurate first class stamp cost, always check the official USPS website or a retailer listing before you mail.
Comparing First Class to Other Services
Choosing the right service depends on speed, size, and price. First class is economical for lightweight letters, while other options serve different needs.
| Service | Price (Starting) | Delivery Time | Best For |
|---|---|---|---|
| First Class | $0.66 | 1–3 days | Letters, postcards, lightweight flats |
| Priority Mail | $9.35 | 1–3 days | Small packages, time-sensitive items |
| Media Mail | $3.21 | 2–8 days | Books, CDs, educational materials |
| Retail Rate | Variable | 1–3 days | Higher cost at retail stores, but convenience |
How Weight and Size Affect Cost
First class pricing covers up to 1 oz for the base rate. Once your item exceeds that threshold, each additional ounce or fraction thereof adds $0.24. Lengthy or rigid pieces may also be classified as nonmachinable, which adds an extra surcharge.
Weight Tiers and Costs
Understanding how weight impacts what you pay can help you save. Below is a simple breakdown for first class letters or flats:
| Weight | Price | Notes |
|---|---|---|
| 0–1 oz | $0.66 | Standard base rate |
| 1–2 oz | $0.90 | Base + 1 additional ounce |

| Over 3 oz | Contact USPS | Pricing moves to parcel services |
Where to Buy and Save
You can purchase first class stamps at post offices, grocery stores, banks, and online retailers. Buying in booklets often matches the official rate, while rolling meters or online print-and-mail discounts can lower your cost per piece for bulk mailings.
