How to Calculate Cost Per Item?

Example Problem:

The following example outlines the steps and information needed to calculate the Cost Per Item.

First, determine the total number of items purchased. In this case, we are looking at 10 different pieces of clothing.

Next, determine the total cost of all of the items. In this case, all the items come out to $320.00.

Finally, calculate the cost per item using the formula above:

CPI = TC / #I

CPI = $320.00 / 10

CPI = $32.00/item
