Energy Bill Estimator by Reliant Energy
People look for tools and tips to help them plan and budget for future utility bills. Utility cost calculators can also help customers see if they are paying more or less than the average consumer.
Why use an electricity bill estimator?
The Reliant Bill Estimator® calculates only your potential electricity bill, not other utilities like gas or water.
• We use historical information on the provided address, then calculate an estimated monthly electricity bill based on past usage, starting with a 10.9 cent per kWh price.
• Enter the amount you pay per kWh — or the per kWh rate as listed on the site where you are shopping for electricity — and recalculate your estimated monthly costs.
Estimating your electric bill with the Reliant Bill Estimator®
Calculating your electric bill with the Reliant Bill Estimator® can help you make an informed decision about which plan fits your budget and how much you can expect to pay depending on the size and location of your home. Remember that factors like the weather, your own preferences on HVAC use and even landscaping can affect what you will actually pay. Nonetheless, this is a great place to start.
How can I estimate my electricity bill?
Enter your address into our tool to estimate your electricity bill. We use the address’s historical energy usage, multiply it by 10 cents per kWh or an average electricity price of your choice, and estimate what you may owe1.
If you want to find a more exact estimate, find the kWh of each appliance and multiply each number by your current electricity rate. To do this, you need to follow these four steps:
- Find the appliance’s wattage and multiply it by the number of hours it is used
- Divide the number by 1,000 to convert it from watts-hours to kilowatts-hours (kWh)
- Multiply the kWh by the electricity rate on your bill
- Repeat these steps to find the cost of energy for each appliance and add them together to find the cost of energy of your entire house each month
This will give you a more accurate look at your electricity cost per month, but it can be time-consuming. For an easier solution, try our bill estimator tool and alter the cost per kWh to find the price you want. If you already have an account, sign up for weekly summary emails to see your household energy usage.

Average electricity bill in Texas
Your monthly electricity usage and subsequent costs will largely depend on the size of your home and the season. You’ll likely see a rise in your electricity bill during warmer and colder months because of increased air conditioner and heater use to maintain comfortable home temperatures. That said, the U.S. Energy Information Administration (EIA) releases average residential electricity usage and cost information every year. Based on their data from 20152, some of the average electricity figures for homes in Texas (including regulated and deregulated markets) are as follows:
Average residential electricity usage and cost3
The average monthly residential electricity bill in Texas is $136
The average residential electricity rate in Texas is 11.56¢/kWh4
Residential electricity usage in Texas averages 1,176 kWh per month
Remember that bills can vary widely by season. Our Reliant energy experts estimate that a summertime electricity bill for an average Houston, Texas, home of about 2,400 square feet could be around $288, whereas a bill during a month with less extreme temperatures could be as low as $72. The weather in Texas is unpredictable, and house sizes and general energy efficiency vary greatly. Keep that in mind when trying to predict what your future bills might be.
The figures above depict overall averages in Texas. This information, along with the Reliant Bill Estimator® should be used for informational purposes only. Your exact figures will vary depending on the area you live in, the size and age of your home, the age of your appliances, weather conditions and a variety of other factors. For a more in-depth list of factors that could affect your electricity usage, see below.

How do electricity providers calculate electricity cost per month?
Reliant calculates the electricity cost per month by multiplying the home’s energy usage (kWh/month) by the electric rate in your chosen electricity plan. If you don’t know your electric rate or need a quick estimate, our bill estimator tool takes the historical energy usage at the address entered and calculates the estimated electricity cost per month, starting with 10 cents per kWh. Our tool can also estimate the electricity cost per month of the area as well as provide results based on different electricity rates. This estimate does not include additional fees associated with your electricity bill, such as TDSP, taxes, and base charges. These fees are a significant portion of your electricity bill and should be taken into consideration.

How do I find out what utility company delivers electricity to my property?
The best way to find out which utility company services your property is to look at your current electricity bill. If you can’t find the information on your bill, then it is best to call your current energy provider and ask them for the utility company’s information. It’s important to know your utility company in the case of a power outage or other emergency in your area.
How much is the average electric bill for an apartment?
The average electric bill for Texas apartments is estimated around $89. Using data from the U.S. Energy Information Administration (EIA), the average energy usage for an apartment is approximately 741 kWh/month1 and the average cost of electricity for Texas is around 12 cents per kWh2. If we multiply these two numbers together, the average monthly electric bill for an apartment comes out to $89 (all numbers have been rounded to the nearest whole number). This estimated number is an average and will fluctuate depending on your energy usage, the size of your home, your electric rate and other fees.
For a Texas home, the average electricity bill is $154. Using the same data as before, the average energy usage in a single-family home is 1,280 kWh/month1. Multiplying this number by 12 cents per kWh2, the average electric bill for a Texas home is $154 (all numbers have been rounded to the nearest whole number). This number is also an estimated average and will fluctuate depending on your unique situation.
