Understanding how your electricity bill is calculated can help you better manage your energy use and monthly costs. Your bill is based on several factors, including how much electricity your home uses, your electricity rate and other applicable charges. By learning how these pieces work together, you can estimate your electricity costs and identify ways to use energy more efficiently.
(Total kilowatt-hours (kWh) used in a month x Electricity rate) + Taxes and fees = Monthly electricity bill
For example, if your home uses 1,000 kWh and your rate is 15¢ per kWh, your electricity cost would be approximately $150 before additional charges.
Understanding how much electricity your household uses each month can be an important step toward managing your energy efficiency. See how usage, rates and other charges can affect an average electric bill to further review what impacts monthly electricity costs.
Most electric bills show a single kWh usage amount and cost. The amount and cost lump together usage from appliances, electronics and your HVAC, which is typically considered a high-usage system in a home. Identifying and calculating individual appliances that use the most energy helps you make more informed choices about when and how often you use them.
A kilowatt shows how fast an appliance uses electricity at a given moment, while a kilowatt-hour shows how much electricity it uses over time. So, a 1.5-kW window AC unit running for 4 hours would use 6 kWh.
1. Calculate daily kWh
Watts × hours used per day ÷ 1,000 = daily kWh
2. Estimate daily cost
Daily kWh × electricity rate = estimated daily cost
3. Estimate monthly cost
Estimated daily cost × days used per month = estimated monthly cost
Learning the kWh total helps you estimate the energy-use portion of your bill, though your final amount may also include delivery charges, taxes, fees and other plan-specific charges.
An EFL shows the average price per kWh at 500, 1,000 and 2,000 kWh of monthly usage. Reviewing the required EFL for your chosen electricity plan makes it easier to compare plan details and estimate costs for AC use, EV charging and more.
Follow these steps to learn about each major home appliance’s energy consumption.
Multiply the appliance wattage by the number of hours you use it each day.
Example: 120-watt television × 4 hours per day = 480 watt-hours per day
Divide watt-hours by 1,000 to convert the number into daily kWh.
Example: 480 ÷ 1,000 = 0.48 kWh per day
Multiply daily kWh by the number of days used each month, then multiply that monthly kWh total by your electricity rate.
Example monthly usage: 0.48 kWh per day × 30 days = 14.4 kWh per month
Example monthly cost: 14.4 kWh × $0.12 per kWh = $1.73 per month
For this example, a 120-watt television costs about $1.73 per month to run.

Uncover what uses the most electricity in your home and how different appliances can affect your overall usage.
Use the yellow EnergyGuide label to compare similar appliance models by estimated yearly energy use, annual operating cost and cost range. Then you can multiply the annual kWh by your electricity rate for a more personalized estimate.
Every appliance in your home plays a role in your overall energy consumption, but some use far more electricity than others. Understanding how to save energy for each major appliance type can help you cut costs without sacrificing comfort. Along with choosing ENERGY STAR-certified appliances and electronics, a few simple tips can help you save electricity at home.
Based on a report from the U.S. Energy Information Administration, Texans have or use these 3 appliances more often than others.
In many Texas areas, you can choose your retail electricity provider, but your local TDSP still delivers power and maintains poles, wires, transformers and meters. Your bill may include supply charges based on your plan and usage, plus TDSP delivery charges. Delivery charges can include a monthly charge and a per-kWh charge.
June through September cooling peak
Texas residential electricity use often increases in summer, with August commonly being the highest-usage month.1
Spring and fall dip
March through May and November are often lower-usage months because HVAC runtime is typically lower.1,2
Electric heating in winter
Winter usage is usually lower, but electric resistance heating or frequent heat pump use can noticeably increase your energy use.1,3
An EnergyGuide label is a yellow label found on many home appliances that shows estimated annual energy use and operating costs. It helps you compare the energy efficiency of similar models so you can make an informed purchasing decision.
To estimate your electric bill, multiply the number of kilowatt-hours (kWh) you use by your electricity rate. Then add any fixed fees, taxes or charges included in your electric plan. Your monthly usage can typically be found on your utility bill or energy dashboard.
To estimate the cost to run an appliance, find the appliance wattage, divide by 1,000 to convert watts to kilowatts, then multiply by the number of hours used and your electricity rate per kWh. For a monthly estimate, multiply that daily cost by the number of days the appliance is used each month.
The basic formula is: Electric bill = Energy usage (kWh) × Electricity rate ($/kWh) + fees and taxes. This calculation provides an estimate of your total cost based on how much electricity you use and the rate charged by your provider.
The average U.S. residential customer uses about 900 kWh of electricity per month, while the average in Texas is about 1,100 kWh per month, according to the U.S. Energy Information Administration. Actual electricity use can vary based on home size, number of occupants, weather, appliances and heating and cooling needs. Reviewing the kWh usage on your monthly electric bill can help you understand how your home compares and identify opportunities to save energy.
A higher-than-normal electric bill can result from increased electricity usage, seasonal weather changes, higher air conditioning or heating use, additional household occupants, or appliances that consume more energy than expected. Changes in electricity rates, delivery charges, taxes and fees can also affect your total bill. Comparing your current bill with previous months can help identify the cause of the increase.
Heating and cooling systems are often among the largest electricity users in many homes. Other common high-energy appliances include water heaters, refrigerators, clothes dryers, electric ovens and cooking appliances. The amount of electricity these appliances use depends on factors such as age, efficiency, settings and how often they are operated.
Delivery charges help cover the cost of transmitting and distributing electricity to your home. These charges are separate from the electricity supply portion of your bill and may include a fixed monthly fee, a usage-based charge or both. In Texas, delivery charges are typically assessed by the local Transmission and Distribution Service Provider (TDSP) and are added to your total electric bill.
To estimate your next electric bill, calculate your expected electricity usage in kilowatt-hours (kWh) and multiply it by your electricity rate. Then add any fixed monthly fees, delivery charges, taxes, and other applicable charges. Reviewing past bills, seasonal weather patterns, and expected appliance usage can help you create a more accurate estimate.
Unplugging certain electronics and devices can help reduce electricity costs by eliminating standby power consumption, sometimes called "phantom" or "vampire" energy use. Devices such as televisions, gaming consoles, chargers and computer equipment may continue using small amounts of power when not actively in use. Using smart power strips can make it easier to manage multiple devices and reduce unnecessary energy use.
Electricity rates in Texas can vary based on factors such as location, provider, plan type, contract length and market conditions. Rather than focusing on a single "good" rate, it's important to compare the total average price shown on an Electricity Facts Label (EFL), including energy charges and delivery charges. Reviewing plans based on your typical monthly kWh usage can help you find the best fit for your needs.
Smart meters automatically record your home's electricity usage and securely transmit that information to the utility or grid operator. Unlike traditional meters that require manual readings, smart meters collect usage data throughout the billing period, helping improve billing accuracy and providing insights into energy consumption patterns. Some energy providers and online account tools may use this data to help customers better understand their electricity usage.
