2,500 sq ft – 1,250 to 2,500 kWh
3,000 sq ft – 1,500 to 3,000 kWh
3,500 sq ft – 1,750 to 3,500 kWh
4,000 sq ft – 2,000 to 4,000 kWh
4,500 sq ft – 2,250 to 4,500 kWh
5,000 sq ft – 2,500 to 5,000 kWh
Remember that your actual usage depends on many factors, such as weather, number of occupants, appliances, and more.
Use our kWh calculator for a more customized estimate, and review past bills to understand your unique usage patterns.

Thank you for helping me find the best price based on how much energy I used in the last 12 months. This saved me a lot of time. We don’t use exactly 1,000 kWh every month, so using that number doesn’t show us the best price. I actually picked the second cheapest because I wanted 100% green energy. Great website, everything was easy to do!

kWh Electricity Calculator FAQs
How is kWh calculated?
kWh is calculated by multiplying an appliance’s power in kilowatts by the hours you use it. It’s like figuring out how much gas your car uses on a trip. A 2-kilowatt air conditioner running for 3 hours uses 6 kWh. This simple math helps you understand your energy use.
How to calculate kWh?
To calculate kWh, multiply your device’s power (in kilowatts) by how long you use it. Do you have watts? Just divide by 1000 first. So, a 100-watt bulb (0.1 kW) for 10 hours uses 1 kWh. It’s an easy way to monitor your electricity consumption.
How to calculate kWh cost?
Calculating kWh cost is like totaling a grocery bill. Multiply the kWh you’ve used by your electricity rate. If you used 500 kWh at 12 cents per kWh, you’re looking at $60. This simple calculation helps you understand and manage your energy spending.
How to calculate kWh per day?
To calculate your daily kWh, add up the energy used by all your appliances in 24 hours. For each device, multiply its power by how long you use it daily. This process is like creating an energy diary for your home, helping you spot where you might be using more power than you realize.
What does kWh mean?
kWh stands for kilowatt-hour. Think of it as the ‘gallon’ of electricity use. It measures how much power you’re using over time. One kWh is the energy a 1000-watt appliance uses in an hour. Understanding kWh helps you make sense of your electricity bill.
How many kWh will I use?
Your kWh use depends on your home size, appliances, and habits. An average Texas home uses about 1,000 kWh monthly. Check your past bills or use an online calculator for a personalized estimate. It’s like predicting how much gas you’ll use on a road trip.
Is 50 kWh a day a lot?
Yes, 50 kWh a day is a lot. It’s like leaving all your lights on 24/7. The average Texas home uses about 33 kWh daily. If you’re hitting 50, you might want to check for energy-hungry appliances or habits that need tweaking.
How much time is 1 kWh of electricity?
1 kWh is like an energy budget that different appliances spend at different rates. It could power a 100-watt light bulb for 10 hours or a 2,000-watt hair dryer for 30 minutes. How long it lasts depends on what you’re powering; just like how far a gallon of gas gets, it depends on your car.
How to calculate kWh from watts?
To calculate kWh from watts, divide the watts by 1000 to get kilowatts. Then multiply by the hours used. A 60-watt bulb used for 5 hours? That’s 0.3 kWh: (60 ÷ 1000) × 5 = 0.3 kWh. It’s a handy skill for understanding your energy use.
How much kWh does a house use?
The average residential electricity consumption in the United States is about 10,715 kWh per year, which translates to approximately 893 kWh per month, according to data from the U.S. Energy Information Administration (EIA).
According to the U.S. Energy Information Administration (EIA), the average annual electricity consumption for a Texas residential utility customer is about 14,112 kWh per year. This translates to approximately 1,176 kWh per month.
