Understanding USPS Rates

When mailing a 5.7-ounce 9x12 envelope as of August 2023, you should refer to the United States Postal Service (USPS) rates. The USPS offers various services, and First-Class Mail is typically used for lightweight envelopes. To determine the exact amount, you need to consider the weight and the service type.

USPS First-Class Mail Rates as of 2023

For a 9x12 envelope weighing over 1 ounce, the following rates apply:

First Ounce: $0.66 Each Additional Ounce: $0.24

Calculating Postage for a 5.7-Ounce Envelope

Let’s break down the calculation step-by-step:

For the first ounce, the cost is $0.66. The envelope weighs 5.7 ounces, and to calculate the additional weight, we subtract the first ounce: 5.7 - 1 4.7 ounces. Since the weight is rounded up to the nearest whole number, the additional weight is 5 ounces (rounding 4.7 up to 5). For the additional 5 ounces, multiply 5 by $0.24: 5 x $0.24 $1.20. Total postage: $0.66 $1.20 $1.86.

It's important to check for any updates or changes in postal rates after August 2023, as they can affect the final cost.
