How much electricity does a house use?
About 900 kWh a month for an average US home, close to 10,800 a year. Your bill gives your own number; the calculator turns it into kWh a day and compares it with the average.
Compare your home
The US average: roughly 10,700 to 10,800 kWh a year, about 900 a month. Small homes use near 500 a month, large ones over 1,500.
Reading your own number
Your bill states the electricity you used in kilowatt-hours, measured by the utility meter between two readings. The number of days changes from bill to bill, so kWh a day is the fair way to compare one month with another. Twelve bills added together give your yearly use, which smooths out summer and winter.
Why homes differ so much
The average hides a wide spread: about 500 kWh a month in a small home, over 1,500 in a large one. Size, the number of people and the climate do most of it. Heating, air conditioning and water heating are the biggest single uses, and their share moves with the weather, which is why a bill in July or January can look nothing like one in May.
