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, there are many online tools that can help you estimate the average electricity bill and usage of a home by using a home address.

Your average electricity bill is more impacted by the efficiency of your appliances than the size of your home!

Other ways to accurately predict the energy costs of a home is by making predictions based on known data points. For example, The US Energy Information Administration, in 2018,  determined that the average electricity bill in the United States was $117.65. 

Therefore, it is safe to say that the average household used 914 kilowatt-hours of electricity purchased at an average cost of 12.87 cents. To determine the average electricity bill, like I did, you can follow this formula:

Average kW⋅h used × Average ¢ per kW⋅h ÷ 100 = Average Electric Bill.

(Average kilowatt-hour used multiplied by average cents per kilowatt-hour divided by 100 equals average electric bill)

With that said, the average electricity bill for a 3-bedroom house with two residents would be anywhere between $87 and $93. Whereas, the average electricity bill for a 3-bedroom house with three residents would be around $93 to $100.

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, Alaska, Massachusetts, Connecticut, and Rhode Island. It shouldn’t be surprising to see states with the coldest winters with also the highest cost of electricity. In the states with the highest electricity price, the average monthly electric bill was above $160.

On the other hand, states with the lowest electricity prices were North Dakota, Idaho, Arkansas, Washington, and Louisiana. States with the lowest electricity price had an average monthly bill of under $150 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, Connecticut had the highest average bill for electricity at a monthly cost of $165.32. Whereas, New Mexico had the lowest average bill for electricity at a monthly cost of $75.28. Therefore, it is safe to say that with the same usage, the average electricity bill for a 3-bedroom house in Connecticut will be substantially higher than in New Mexico. 


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 the size of your home. 


Generally speaking the electricity bill of a home costs an average of .7 to $0.10 per square foot.

Why is my Electric Bill so High?

If your 3-bedroom home has a very high electric bill, then your home might be in need of some updating. For example, a LED light bulb can power your house for 30000 hours at the cost of around $30. An incandescent light bulb would cost roughly $200 to light your home for the same length of time. Converting your home to LED lightbulbs is well worth the investment! 


When searching for new appliances, you should also look for the energy star symbol. The energy star symbol ensures that a product you are purchasing is optimized to be energy-efficient. Dated appliances use up a lot more energy and cost you more in the long run.  


There is also an untrue assumption that energy efficient products cost more money than non energy efficient products. However modern technology has led to lower prices and more affordability in terms of energy efficiency. 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.

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 simply multiple your homes square feet by .7 or .10. If you realize that your bill is coming out higher than the national average, then 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 bill. 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.  

The Mercury News, a Bay Area New 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 cost of the kilowatt-hours. 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.

Tips to Save Money

Energy Sage shows that a clothes dryer that is energy efficient can save you around $210 a year. Whereas, a clothes washer that is energy efficient  can save you up to $50 a year. Just by replacing an old washer and dryer system, you would be saving around $260 a year.


Another option is to reduce the areas where heat is fleeing your home. An easy way to do this is by adding draft protections like:



However, before you work on reducing your heating bill (which will reduce your electric bill), make sure you make some basic changes. For example, all of your lightbulbs need to be LED. If you have done that, then update all of your power surges (light strips) to a power conserving model


These simple changes should drastically reduce your electric bill! 

However, 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 you consume a lot of energy, then 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 a HVAC system will have a significantly higher electric bill then 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 control over how much electricity you should use. If you think your bill is too high, then there are various steps you can take to reduce your bills.
