Kilowatt Hour Cost Formula: Cost Per kWh x Wattage of Appliance /1000 x Hours Appliance is Running

Kilowatt Hour Cost Definition Use our free Kilowatt Hour Cost Calculator to quickly perform your calculations! If you have noticed that your electric utility bills have been steadily increasing, you can easily figure out how much each of your appliances and other gadgets costs to run. Learning how much energy you and your family are consuming in such precise detail will enable you to quickly take steps to drastically reduce your usage, as well as your bill.

There are Only Three Pieces of Information to Enter:

Type in the cost per kilowatt hour (KWH). You can find this information on your latest electric utility bill, or call the utility to ask them if you don’t have your bill handy. For example, you might type in “.05509.”

Type in the wattage of the appliance. For example, a lamp in your living room may take a 60-watt bulb, so you type in “60.”

Type in the hours the appliance or other item is running. For example, your family may watch TV every night from 5 p.m. until midnight, so you would enter 7 hours to find out how much energy the TV consumes per day, or 49 hours to get the weekly amount.

Click the “Calculate” button to find out the energy cost of your designated appliance. You can repeat the calculation for as many different appliances as you want. What’s more, you can experiment by typing in different wattage amounts to see how much money you can save by using a more efficient device.

Take Steps to Reduce the Amount of Electric Power You Consume:

Go around your home and identify each high-wattage light bulb. See which ones you can feel comfortable about replacing with compact fluorescent bulbs. You can get fluorescent bulbs that consume only 13 watts while providing the same amount of light as a standard light bulb that consumes 60 watts.

Make a habit of turning off lights when you leave a room. Encourage each family member to follow your example. Why waste energy and inflate your electric utility bill when you can easily turn off an unneeded lamp?

Use your thermostat to precisely regulate how hot and how cold you want the temperature for your home. If you have an older analog thermostat, have a digital model installed that enables you to enter the exact temperature you want. You can also program the thermostat to begin cooling down the house an hour before you come home from work, if you don’t want to run the air conditioning all day.

Wear lighter clothes in the summer and put on sweaters and slippers in the winter to further reduce the electricity you and your family consume from heating and cooling the home.

Set up a clothesline in your backyard or anywhere else you have room. Electric dryers consume a lot of kilowatts, and you can save energy and money by first hanging up your clothing, sheets and towels up to dry. After they have completely dried off in the free sunlight and wind, fluff them up in the dryer for 15 minutes. Your pocketbook will thank you.
