• CP is the total cost of power ($) • W is the wattage usage (watts) • T is the time (hrs) ## How to Calculate Wattage Price? The following example problems outline how to calculate Wattage Price. Example Problem #1 1. First, determine the total cost of power ($).
1. The total cost of power ($) is given as 4,000. 2. Next, determine the wattage usage (watts). 1. The wattage usage (watts) is calculated as: 500. 3. Next, determine the time (hrs). 1. The time (hrs) is found to be: 2. 4. Finally, calculate the Wattage Price using the formula above: WP = CP / (W*T) Inserting the values from above yields: WP = 4000/ (500*2) = 4.00 ($/Whr)

Example Problem #2

The variables needed for this problem are provided below:

total cost of power ($) = 50 wattage usage (watts) = 29 time (hrs) = 120 This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer. WP = CP / (W*T) = ($/Whr)
