Electric Bill Calculator: what will your bill be?
Enter your ZIP code and monthly usage. The calculator uses the average residential price your utility actually charged in 2025 (EIA Form 861, fees and taxes on the bill included), not a national guess. The U.S. average was 17.2¢ per kWh and $151 a month.
How the bill is calculated
Bill = kWh used × average price per kWh. The average price we use is your utility's total residential revenue divided by the kWh it sold to homes in 2025, as reported to the U.S. Energy Information Administration. That figure already spreads the fixed monthly customer charge, riders and fuel adjustments across every kWh, so it is close to what you pay per kWh "all in" at typical usage. At very low usage your real price per kWh is higher, because the fixed charge is spread over fewer kWh.
In states with retail choice (Texas, Pennsylvania, Ohio, Illinois, New York and others), customers who buy their energy from a retail supplier pay the utility only for delivery. For them, the utility's own average describes the default service price, and the supplier's contract price replaces the energy part.
Average monthly usage and bill by state
See the full table on average electric bill by state. The highest average bills are in states with high usage (air conditioning in the South) or very high prices (New England, California, Hawaii), not always both.
Frequently asked questions
How many kWh does an average home use per month?
874 kWh in 2025 across the U.S. It ranges from about 494 kWh in the lowest state to 1,225 kWh in the highest.
Why is my bill higher than kWh × rate?
Your bill may list a fixed customer charge, delivery and transmission charges, fuel or power-cost adjustments and taxes separately. The average price used here includes all of them on average. If you have your bill, divide the total by the kWh used: that is your personal all-in price, and you can enter it above.
How much does it cost to run an appliance?
Watts × hours per day × 30.4 days ÷ 1,000 = kWh per month, times your price per kWh. A 1,500-watt space heater running 4 hours a day uses about 182 kWh a month, which is about $31 at the U.S. average price.
