## How to calculate media mail cost?

The following example explains how to calculate the cost of sending media via mail.

First, determine if the media weighs more than 1 pound. For anything under 1 pound, there is a flat rate of $2.66. For this example, the media is found to be greater than a pound.

Next, determine the total weight being sent. In this case, a book weighing 7.5 pounds is being sent.

Finally, calculate the cost to send the book using the formula above:

C = $2.66 + $.51 * (W-1)

C = $2.66 + $.51 * (7.5-1)

C = $5.97
