Enter the total amount of power generated in kilowatts and the total cost into the calculator to determine the cost per kilowatt.

Cost Per Kilowatt Formula

The following equation is used to calculate the Cost Per Kilowatt.


  • Where CPKW is the cost per kilowatt ($/kw)
  • TC is the total cost ($)
  • P(KW) is the power in kilowatts (kw)

To calculate the cost per kilowatt, simply divide the total cost by the number of kilowatts (kw)

What is Cost Per Kilowatt?


A cost per kilowatt measures the cost per unit of power. In this case the power is in kilowatts.

How to Calculate Cost Per Kilowatt?

Example Problem:

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

First, determine the total cost. In this example problem, the total cost is calculated to be $210.00.

Next, determine the number of kilowatts. For this example, the number of kilowatts is 10.

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


CPKW = $210 / 10

CPKW = $21 /kw
