How Does the Electricity Bill Calculator Work?
This calculator estimates your monthly electricity bill based on your home size and the number of people in your household. Select your primary state, choose a state to compare, pick your home size and household size — and get an instant side-by-side cost comparison.
The calculation uses average residential electricity rates by state from the U.S. Energy Information Administration (EIA). Base usage ranges from approximately 400 kWh/month for a studio to 1,500 kWh/month for a 4+ bedroom home. Household size adjusts usage by up to 40% to reflect real consumption patterns.
Results show your estimated monthly bill in dollars, the rate in cents per kilowatt-hour (¢/kWh), and how your state compares to the US national average. You can also view a 12-month price history chart for both states.
About the Data
All electricity price data comes directly from the U.S. Energy Information Administration (EIA) — the official US government source for energy statistics. Data covers all 50 states plus Washington D.C. and is updated monthly. Note that EIA publishes data with a 1–2 month delay, so the most recent month shown may not reflect today's current rates.
Frequently Asked Questions
What is the average electric bill in the US?
The average monthly residential electricity bill in the United States is approximately $130–$180, depending on home size, location, and season. States like Hawaii and Connecticut have the highest rates, while states like Louisiana and Oklahoma tend to have the lowest.
Which US state has the cheapest electricity?
Louisiana, Oklahoma, Arkansas, and Idaho consistently have some of the lowest residential electricity rates in the country — often under 12¢/kWh. This is largely due to access to cheap natural gas and hydroelectric power.
Which US state has the most expensive electricity?
Hawaii has by far the most expensive electricity in the US, often exceeding 40¢/kWh due to its reliance on imported oil. On the mainland, Connecticut, Massachusetts, and California tend to have the highest rates.
How much electricity does a 2-bedroom apartment use per month?
A typical 2-bedroom home in the US uses approximately 900–1,100 kWh per month, though this varies by climate, appliances, and whether heating and cooling are electric. At the US average rate of around 17¢/kWh, that translates to roughly $150–$190/month.
Why is my electric bill so high compared to my state's average?
Your bill can be higher than average due to electric heating or cooling, older appliances, poor insulation, a larger home, or a higher local utility rate. The state average reflects all household types — individual bills can vary significantly.
