The United States Postal Service (USPS) sets mailing rates that change periodically throughout the year. As of 2024, knowing these rates helps you budget for sending mail and understand what you pay for different types of correspondence. Postage rates vary depending on the mail class you choose, the weight of your item, and where it's being sent.

First-Class Mail is the most common type of postage for letters and small packages. A standard letter weighing one ounce currently costs 68 cents to mail within the United States. This rate applies to envelopes and cards you send through regular mail service. Each additional ounce adds 24 cents to your postage cost. This means a two-ounce letter costs 92 cents, and a three-ounce letter costs $1.16.
The USPS last adjusted rates in July 2023 and again in January 2024. These adjustments happen several times per year. Rates typically increase slightly each year due to operational costs. The Postal Regulatory Commission must review and approve rate changes before they take effect. You can find the most current rates by visiting USPS.com or visiting your local post office.
Different mail classes serve different purposes and have different costs. First-Class Mail arrives in 1-3 business days. Priority Mail Express provides overnight delivery for important documents and packages. Priority Mail is a mid-range option that typically arrives in 1-3 business days and costs more than First-Class Mail but offers tracking. Media Mail is the least expensive option for books and educational materials but takes 2-8 business days.
Practical takeaway: Before mailing anything, weigh your item and confirm which mail class fits your timeline and budget. A postage scale costs $10-30 and helps you determine exact postage costs. This prevents paying too little postage, which can result in your mail being returned or delayed.
First-Class Mail is the standard mail service most people use for letters, bills, and greeting cards. This service includes tracking for mail pieces over 13 ounces and automatic insurance coverage for Priority Mail Express. The current rate for a one-ounce letter is 68 cents within the United States. Postcards cost 53 cents. Large envelopes (known as "flats") that weigh up to one ounce cost $1.24.

Weight determines your First-Class Mail cost more than anything else. The USPS divides First-Class Mail into categories based on size and weight. Letters that fit in a standard envelope and weigh one ounce or less fall into the basic letter rate. If your letter weighs 1.1 to 2 ounces, you pay the one-ounce rate plus 24 cents. This incremental pricing continues for each additional ounce up to 13 ounces. Once mail reaches 13 ounces, it must be sent as Priority Mail instead.
First-Class Mail pieces receive delivery within 1-3 business days. This timeframe is not guaranteed, but the USPS aims to meet this standard. Mail sent to nearby addresses typically arrives in 1-2 days, while mail sent across the country may take 2-3 days. Weather events, holidays, and high mail volumes can affect delivery times. Pieces mailed on Friday may not arrive until the following Tuesday or Wednesday.
The contents of First-Class Mail are protected from inspection unless there is reasonable suspicion of illegal activity. This privacy protection is one reason people choose First-Class Mail for sensitive documents. The USPS will not open First-Class Mail pieces to check contents unless required by law. This applies to letters, cards, and sealed envelopes.
One advantage of First-Class Mail is that postage is relatively affordable for most correspondence. A single letter costs less than a dollar, making it economical for routine communications. Bulk mail senders can negotiate discounts through commercial accounts, which reduces per-piece costs significantly. Nonprofit organizations may qualify for reduced postage rates on certain mail pieces.
Practical takeaway: Use First-Class Mail for regular letters, bills, and greeting cards. Always use a postage scale to confirm weight before sealing your envelope. Overpaying postage wastes money, while underpaying causes mail to be returned. Stamps purchased in books of 20 or rolls of 100 cost the same per stamp as individual stamps and never expire, making them a practical way to stock up.
Priority Mail provides faster delivery than First-Class Mail and includes tracking and insurance at no extra cost. Priority Mail rates depend on weight and the distance the package travels. A Priority Mail package weighing up to one pound costs $10.45 to mail within the United States. Packages weighing 1 to 2 pounds cost $15.60. Prices continue to increase based on weight, reaching $50.35 for packages weighing up to 70 pounds.

Priority Mail guarantees delivery within 1-3 business days, though many packages arrive sooner. The exact delivery timeframe depends on the distance and the current mail volume. Packages sent to nearby addresses often arrive in 1 day, while cross-country packages typically take 2-3 days. The USPS provides a delivery tracking number with each Priority Mail package, allowing senders and recipients to monitor progress.
Priority Mail Express is the fastest USPS service and guarantees next-business-day delivery to most addresses. A Priority Mail Express envelope weighing up to half a pound costs $32.70. Larger packages cost more based on weight and destination. Priority Mail Express service includes $100 in insurance coverage at no cost. If your package is lost or damaged, you can file a claim for reimbursement up to the insurance limit.
Flat-rate options provide predictable pricing for Priority Mail and Priority Mail Express. A Priority Mail Flat Rate Small Box costs $10.45 regardless of what you put inside (as long as it fits and weighs a reasonable amount). A Medium Flat Rate Box costs $15.60. A Large Flat Rate Box costs $21.60. These options work well when you know the size but are uncertain about exact weight, or when the contents are heavy relative to the size.
Priority Mail and Priority Mail Express both come with online tracking. You can check tracking information on USPS.com by entering your tracking number. Many postal workers will also provide tracking information if you ask them about your package. Tracking shows when your package is picked up, when it arrives at sorting facilities, and when it is out for delivery. Final tracking updates show when the package is delivered and often include a photo of the delivery location.
Practical takeaway: Choose Priority Mail for packages that need to arrive within a few days and cost less than overnight shipping. Use Priority Mail Express only when next-day delivery is essential, as the higher cost may not justify it for routine packages. Flat-rate options work well for small or medium boxes, especially if the contents are heavier than they appear.
Media Mail is a specialized mailing service designed for books, educational materials, DVDs, and similar items. It is the least expensive USPS option for qualifying items. A Media Mail package weighing up to one pound costs $3.45. Packages weighing 1 to 2 pounds cost $4.45. Larger packages cost $5.45 for weights up to 70 pounds. The price difference between Media Mail and Priority Mail is substantial—a two-pound package costs $4.45 via Media Mail but $15.60 via Priority Mail.

Media Mail delivery typically takes 2-8 business days, making it suitable for non-urgent items. The USPS handles Media Mail with less priority than First-Class Mail or Priority Mail, which explains the lower cost. Media Mail pieces are not tracked or insured unless you purchase additional services. This makes Media Mail appropriate for items of lower monetary value or for situations where exact delivery timing is not critical.
Parcel Select Ground is another budget option for packages. It costs less than Priority Mail but more than Media Mail and typically takes 2-8 business days for delivery. Parcel Select Ground works well for heavier items that do not need priority handling. A one-pound Parcel Select Ground package costs approximately $8-12 depending on the destination zone. Like Media Mail, Parcel Select Ground is not
