USPS First Class Mail Rates Explained

The cost of sending First Class Mail through the USPS depends on the weight and size of the package. For example, a 1-ounce letter costs $0.58 to send.

Letters weighing up to 1 ounce are charged at a flat rate, but the cost increases with weight. This means that a 2-ounce letter costs $1.16, a 3-ounce letter costs $1.74, and so on.

If you're sending a package that's over 1 pound, the cost is calculated based on the weight and zone of delivery. For example, a 2-pound package sent to a zone 1 destination costs $3.80, while the same package sent to a zone 4 destination costs $5.20.

The USPS also offers discounts for bulk mailings, which can be a cost-effective option for businesses or individuals sending large quantities of mail.
