Electrical Energy Cost Calculator

This is designed to give an idea of the costs of various daily things we do in our homes that are electrical in nature. This calculator is generic in that it assumes averages for various appliances. The cost per KWH is found at the top, the default is the national U.S. average cost per KWH $0.1099 as of January 2011 (found at U.S. Energy information Administration), but you can input whatever rate you pay per KWH found on your energy bill.

How much does it cost to wash a load of clothes or sleep under the electric blanket? What does it cost to leave a light on all night? We have collected national average values of energy use to find out how much you are paying to operate the different devices in your home. If you know the EXACT information for your device or appliance, you might want to see our equipment cost calculator for commercial use, or see our appliance cost calculator for residential use. You might also find our energy pollution calculator for additional information, and our carbon pollution calculator, interesting.

Lighting
To find out how much your lighting costs, enter the number of bulbs you use, then choose a bulb type. (A common incandescent bulb is 60 (we have stated 60 as typical), 75 or 100 watts, and a standard fluorescent bulb is 40 (we have stated 40 as typical) or 60 watts. An outdoor spotlight or floodlight may use 150 (we have stated 150 as typical) to 500 watts. Light bulb wattage is usually printed right on the bulb. We have provided six sets of data entry fields and a wide array of lamps types for the likely event you must use different types of light bulbs. You may have to run the calculator several times for a total.

All of this electrical power would cost on your electric bill.

Kitchen Appliances
In order to determine how much your kitchen appliances cost for general usage, select the appliances you want to calculate for by checking the Include box, or if applicable, the drop down box value, then select the amount of time the appliance will be on. (In the case of the dishwasher and coffee pot, you will enter the number of uses instead of minutes.) In this set of calculations, an electric water heater is assumed. These results are calculates using national averages for a typical device. Some devices will obviously vary.
