How this calculator works
The bill estimate is your monthly usage in kWh multiplied by the average residential price of electricity in your state.
State prices come from the U.S. Energy Information Administration’s Electric Power Monthly, table 5.6.A (March 2026 data). The default usage of 865 kWh is the 2024 U.S. average per home, from EIA.
Average prices already include most delivery costs, but your utility may add fixed monthly charges, taxes and fees, and rates often change with the season and the time of day.
Example: 865 kWh a month in Texas
- Average rate in Texas: 16.39¢ per kWh.
- Estimated bill: 865 × $0.1639 = $141.77, about $142 a month.
