Enter the total kWh and the cost per kWh ($/kWh) into the KWH to Cost Calculator. The calculator will evaluate and display the KWH to Cost. 

KWH to Cost Formula

The following formula is used to calculate the KWH to Cost. 

TC = TKWH * CPKWH

  • Where TC is the KWH to Cost ($)
  • TKWH is the total kWh 
  • CPKWH is the cost per kWh ($/kWh) 

How to Calculate KWH to Cost?

The following example problems outline how to calculate KWH to Cost.

Example Problem #1:

  1. First, determine the total kWh. The total kWh is given as 900.
  2. Next, determine the cost per kWh ($/kWh). The cost per kWh ($/kWh) is provided as 3.
  3. Finally, calculate the KWH to Cost using the equation above: 

TC = TKWH * CPKWH

The values given above are inserted into the equation below:

TC = 900 * 3 = 2700 ($)


Example Problem #2: 

The variables needed for this problem are provided below:

total kWh = 1200

cost per kWh ($/kWh) = 4

Entering these values and solving gives:

TC = TKWH * CPKWH = 4800.00 ($)
