Electricity calculator

Understanding how energy is used in your home is an important step to managing your energy costs. Our calculator can help.

Simply enter how many of each item you have in each room and the approximate hours per month the item is used. For time periods shorter than one hour, enter a decimal (e.g. 15 minutes = 0.25).

Note: you don't have to fill out the entire form. You can simply see what your toaster costs you a month.
