Enter the total watts (W), the total time (hr), and the cost per watt-hour ($/WH) into the Watt to Cost Calculator. The calculator will evaluate and display the Watt to Cost. 

Watt to Cost Formula

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

WTC = W * T * CPW

  • Where WTC is the Watt to Cost ($)
  • W is the total watts (W) 
  • T is the total time (hr) 
  • CPW is the cost per watt-hour ($/WH) 

How to Calculate Watt to Cost?

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

Example Problem #1

  1. First, determine the total watts (W). The total watts (W) is given as 5000 .
  2. Next, determine the total time (hr). The total time (hr) is calculated as  3 .
  3. Next, determine the cost per watt-hour ($/WH). The cost per watt-hour ($/WH) is found to be .25.
  4. Finally, calculate the Watt to Cost using the formula above: 

WTC = W * T * CPW

Inserting the values from above yields: 

WTC = 5000 * 3 * .25 = 3,750.00 ($)


Example Problem #2

The variables needed for this problem are provided below:

total watts (W) = 7000

total time (hr) = 8

cost per watt-hour ($/WH) = .10

Entering these values and solving gives:

WTC = 7000 * 8 * .10 = 5,600.00 ($)
