How Many kWh Does A House Use Per Day, Per Month, & Per Year

How many kWh does a house use will depend on the wattage of the appliances you're using and for how long. Read along to find out the average kWh consumption per day, month, and year.

Table of Contents

Most American households consume 29 or 30kWh per day of electricity or 870 or 900kWh per month. However, the exact electricity consumption will depend on the size of your home, number of households, and your lifestyle. If you're wondering how many kWh does a house use, you can check out the total wattage consumption of the appliances you're using at your home.

Jackery Solar Generators are reliable, safe, and eco-friendly charging solutions for households. They are portable by nature and can charge small or heavy-duty appliances for long hours to save money on high electricity bills. Read this guide to learn how many kWh a house uses per day, per month, and per year. Also, check out how to reduce home power consumption.

How Many kWh Does A House Use?

Kilowatt-hour, or kWh, is a unit of energy that measures how much electricity an appliance or home consumes in an hour. In 2023, the average annual electricity consumption for a US residential electricity usage was 10,557 kWh. The monthly kWh consumption of residential space was nearly 880 kWh.

There are a few different yet simple ways to calculate your home’s electricity usage. But, before finding out how many kWh your home uses, it’s essential to understand a few related terms – watts and kilowatts.

Wattage measures the electrical power and can be calculated using a simple formula.

Watts = (kWh × 1000) ÷ Hours

Once you have the watts, you can easily calculate kilowatts by dividing the result by 1000.

How Many kWh Does A House Use Per Day, Per Month, and Per Year in the US?

Now let us answer the most commonly asked question, “How many kWh does a house use per day, month, or year.”

In short, there is no single correct answer to the question. A household’s energy consumption may vary depending on factors such as home size, number of home appliances, geographical location, etc.

Let us reveal the daily, monthly, yearly, and instantaneous power usage of a single home in the below table.

What is the Average kWh Usage Per Day?

The average kWh usage per day of a normal household is nearly 29kWh. However, it may vary depending on the size of your house, the wattage of the appliances you are using, and other factors. If you want to calculate the average kWh usage per month, consider calculating the wattage consumption of the appliances you use on a daily basis.

How Many kWh Per Day is Normal?

The average US household electricity consumption is 29kWh per day, which means kWh usage of 870kWh per month. It's worth noting that the electricity consumption might vary depending on the house size, location, and number of members in the household.

For instance, it's normal to draw anywhere around 37kWh per day in the hot, sticky South of the US. This is because you'll be running the air conditioner day and night. On the other hand, if you live in the Northwest or West region, you'll require less energy to heat and cool your home.

What is the Average Kilowatt Usage Per Month?

The average kilowatt usage per month is around 890kWh, which might vary depending on multiple factors. The average electricity bill for a 2 person household in the US is around $150 per month, assuming your monthly consumption is 887kWh per month.

What Uses the Most Electricity in a Home?

Every household appliance has different power requirements, which makes it difficult to understand what appliance consumes more energy. You can always generalize that heavy-duty appliances like washers/dryers, hairdryers, ovens, or ACs are major energy users. Here are the appliances that draw more energy from the grid:

Space Cooling: 16.23%

Space Heating: 15.87%

Water Heating: 11.4%

Refrigerators and Freezers: 6.93%

Lighting: 4.36%

TVs and Related Equipment: 3.52%

Computers and Related Equipment: 2.28%

All Other Users: 39.4%

What Factors Affect How Many kWh Does A House Use?

Several factors can affect a home’s monthly electricity bill and average household electricity consumption kWh per day, including the appliances used daily, where you live, and how big the house is. Let us discuss these factors briefly.

Number & Type of Appliances

If you use more appliances that consume high power, your home will eventually use more kWh. Therefore, the ideal way to lower energy consumption is by using energy-efficient Energy Star-certified appliances.

Home Location

The location of your home has a direct impact on the working of heating and cooling systems. For instance, if you live in a cool area, you will have to run space heaters longer than someone living in a moderate climate.

Average kWh Per Square Foot

As a general thumb rule, a larger home will consume more electricity than a small space. The table below provides monthly kWh consumption and average electricity bill based on square footage:
