Enter the total cost and the total quantity of any variable “X” into the calculator to determine the cost per x.

Cost Per “X” Formula

The following equation is used to calculate the Cost Per “X”.

CPX = TC / Q "X" 
  • Where CPX is the cost per variable X ($/X)
  • TC is the total cost ($)
  • Q”X” is the quantity of the variable X

To calculate the cost per X of any variable, divide the total cost by the quantity of the variable.

What is Cost Per “X”?


Cost Per X describes the cost of something per unit of an X variable. This X variable can be anything from units, to pounds, to days.

How to Calculate Cost Per “X”?

Example Problem:

The following example outlines the steps and information needed to calculate Cost Per “X”.

First, determine the X variable. In this example, the X variable is pounds.

Next, determine the total cost of the item. In this example, the item costs $325.00..

Next, determine the weight of the item in pounds since that is what the X variable is. For this problem, the weight is 10 pounds.

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

CPX = TC / Q “X”

CPX = $325.00 / 10

CPX = $32.50 / X


What types of variables can “X” represent in cost per X calculations?

“X” can represent any measurable unit relevant to the item or service being evaluated. This includes, but is not limited to, units, pounds, hours, pieces, or any other quantifiable measure that can be used to distribute the total cost evenly across.

Why is calculating the cost per X important?

Calculating the cost per X is crucial for understanding the value of goods or services, making informed purchasing decisions, budgeting, and price setting. It helps in comparing costs effectively across different quantities or units, ensuring financial efficiency and transparency.

Can the cost per X formula be applied to services as well as physical goods?

Yes, the cost per X formula can be applied to both services and physical goods. For services, “X” might represent hours of labor, number of sessions, or any other measurable unit of service provision. This allows for a clear understanding of the cost distribution for services rendered.
