How to calculate the average electricity bill for a 3-bedroom house
The average electricity bill of a 3-bedroom house depends on the size and age of the house. Your electric bill may also fluctuate based on the age and efficiency of your appliances. While it is impossible to estimate the exact electric bill of a 3-bedroom house, there are methods you can use to determine a close estimate. For example, many online tools can help you estimate the average electricity bill and home usage using a home address.
Your average electricity bill is more impacted by your appliances’ efficiency than the size of your home!

Other ways to accurately predict energy costs are by making predictions based on known data points. For example, The US Energy Information Administration, in 2020, determined that the average electricity bill in the United States was $117.46.
Therefore, it is safe to say that the average household used 893 kilowatt-hours of electricity purchased at an average cost of 13.15 cents. To determine the average electricity bill, as I did, you can follow this formula:
Average kW⋅h used × Average ¢ per kW⋅h ÷ 100 = Average Electric Bill.
With that said, the average electricity bill for a 3-bedroom house with two residents would be anywhere between $88 and $97. In comparison, the average electricity bill for a 3-bedroom house with three residents would be around $97 to $105.
States with the Highest and Lowest Electricity Prices

It is also important to note that various states have different electricity prices. For example, the states with the highest electricity prices are Hawaii, Connecticut, Alaska, Rhode Island, and Massachusetts. It shouldn’t be surprising to see states with the coldest winters with the highest electricity cost. In the states with the highest electricity price, the average monthly electric bill for a 3-bedroom house was above $160.
On the other hand, states with the lowest electricity prices were Louisiana, Washington, Idaho, Oklahoma, and Arkansas. States with the lowest electricity price had an average monthly bill of under $140 a month. Knowing your state’s electricity price is essential in determining the electric bill you can expect with purchasing a 3-bedroom house.
In 2020, Hawaii had the highest average bill for electricity at a monthly cost of $162.66. In comparison, Utah had the lowest average bill for electricity at a monthly cost of $80.24.
States with the Highest Average Price of Electricity (cents/kWh) | States with the Lowest Average Price of Electricity (cents/kWh) |
1. Hawaii – 30.28 | 1. Louisiana – 9.67 |
2. Connecticut – 22.71 | 2. Washington – 9.87 |
3. Alaska – 22.57 | 3. Idaho – 9.95 |
4. Rhode Island – 22.01 | 4. Oklahoma – 10.12 |
5. Massachusetts – 21.97 | 5. Arkansas – 10.41 |
Electricity prices are ever-changing and there is no one cause for this. Electricity market competition can alter prices; new technologies may be invented; weather changes; federal policies; economic trends may affect the cost of energy. Thus, it is wise to look for a better deal in terms of the only utility in your home.
Use Sq Ft to determine the Average electricity bill for a 3-bedroom house.
However, to accurately determine the average electricity bill for a 3-bedroom house, you must determine the energy usage and cost of electricity in your area based on your home’s size.
Generally speaking, a home’s electricity bill costs an average of .7 to $0.10 per square foot.
Why is my Electric Bill so High?
It’s a question that plagues many homeowners: why is my electric bill so high? One of the most common reasons for this is leaving lights on when you leave the room or house. To combat this, turn off any lights in rooms that are not being used and install motion-sensitive lighting outdoors to avoid forgetting to turn them off. This wastes electricity and sends your bill skyrocketing. However, there may be a variety of factors behind your high monthly charge—and the best approach to address it.
Old Appliances Cost More in the Long Run
There is a common misconception that energy-efficient products cost more money than non-energy-efficient ones. But this isn’t always the case as technology continues to lower prices and make them accessible for everyone who needs one! Therefore, when searching for new appliances, you should look for the energy star symbol. The energy star symbol is your friend when it comes time to purchase new appliances. Dated products use more electricity and cost you in the long run, so make sure that any appliance purchased has the Energy Star logo on its label!
The US Department of Energy estimates that you can save around $2,200 a year through energy-efficient measures. Remember, your home is an investment, and sometimes spending a little more upfront can save you more in the long run.
Another way to save money on your electricity bills is by turning down the temperature on your thermostat during colder months or using space heaters when it gets too hot outside. The more energy-efficient appliances you use, the less energy you use. Finally, hiring an HVAC expert to check for air leaks around doors and windows can help prevent heat loss, which, in turn, can help lower your bill.
Incandescent Lightbulbs are Stealing your Money
If your home is currently using incandescent lightbulbs then you are spending way too much money!
Did you know that an incandescent light bulb costs $200 to light your home for 30000 hours? However, you can save 85% of that cost, per lightbulb, by converting all of your lightbulbs to LED. In other words: A LED light bulb can power your house for 30000 hours at the cost of around $30. This adds up depending on the number of lightbulbs you use, and the savings can be huge.
Heat is Escaping your Home
If your home is feeling a little drafty or you have noticed that the temperature in your home doesn’t feel as warm or comfortable as it once did then you may be losing a lot of heat through air leaks. Fixing air leaks is not only a great way to save money but also increases comfort levels throughout your house.
As mentioned previously, air sealing and insulation are effective ways to reduce heat loss. Siding, weather-stripping doors and windows, caulking cracks, and attics are all simple ways to save money on your energy bills.
The Washington Post has a wonderful infographic on where heat may be escaping that can be quite insightful!
Use Less & Save More
These are just a few ways to fight high energy bills! Not only will you save money, but you can also feel better about your home’s impact on the environment.
Remember that the majority of electricity that powers homes are generated through non-renewable sources, so using less gives us one more way to be good stewards of our Earth.
In the end, knowing why your electric bill is high can help you identify simple yet effective ways to cut costs and live a healthier lifestyle.
The average electric bill for 4 bedroom house
The average electricity bill for a 4 bedroom house should be similar to that of a 3 bedroom house. As mentioned above, your electric bill will be determined by your house size and appliances.
However, in a recent article, The Fioneers stated that due to an “increase in square feet and a decrease in the household size, the average square feet per person [has] almost doubled (560 to 1068 SF/person) from 1975 to 2015.”
Using that data, we could assume that a 3 bedroom house with three people should cost between $50-110 in electricity. However, the average electric bill for 4 bedroom house would increase to $55-$120. This is assuming that the average cost of electricity is .7 to $0.10 per square foot.
Another option is to multiply your home’s square feet by .7 or .10. If you realize that your bill is coming out higher than the national average, you may need to make some cost-cutting changes.
Average pg&e bill for 3 bedroom house
A lot of homeowners are seeing an increase in their PG&E electricity bills. That is because as of October 2020, California imposed statewide fees on PG&E. So, PG&E increased their prices to make up for an increase in their fees along with the additional costs incurred by recent wildfires.
California ranks #6 for Highest Electricty Cost in the nation
The Mercury News, a Bay Area News Group, states, “The new increase for October in monthly bills for PG&E residential customers is 31 cents a month and resulted from the commission’s mandate. As of August, PG&E’s residential customers experienced an average bill of $181.21 a month. That included an average residential electric bill of $127.40 and an average gas bill of $53.81, according to PG&E spokesperson James Noonan.”
It is expected for these price increases to continue upward. By next year, it is expected for monthly bills to increase by an additional $3.
To determine the average pg&e bill for a 3 bedroom house, you will need to determine kilowatt-hours used time the kilowatt-hours cost. With the recent fee increases, pg&e has their cost of electricity between 24¢ & 38¢.
With that in mind, a household of 3 bedrooms with 3-4 residents would see an average bill of between $130-$170.
Determining Your Electricity Bill Requires Time!

In the end, the exact amount that a three-bedroom home costs per month in electricity will vary. If you have very dated appliances and consume a lot of energy, you can expect a bill of over $150 a month. However, an energy-efficient home can expect an average monthly electric bill of under $110.
Don’t Forget! The average electricity bill for a 3-bedroom house needs 12 months of data!
Averages are determined based on a year’s worth of electric bills. Therefore, it is completely normal to see some months with a higher bill than others. For example, a winter where you are consistently running an HVAC system will have a significantly higher electric bill than a month in the fall, where most of your heating and cooling systems are used less.
The good news is that you have a lot of discretion over how much energy you use. If your bill seems excessive, there are a variety of measures you can take to decrease it. Furthermore, look at the average electricity expense of your state: here!
