How to read your electric bill
Your bill has more lines than the price per kWh. Here is what is in it and how to estimate the energy part yourself.
The parts of a bill
Most bills show: an energy charge (kWh used times a price), a delivery charge for wires and poles, a fixed monthly customer charge, riders and taxes. This site covers the average price, which is total revenue divided by kWh sold. It is not your plan rate.
| Part of the bill | What it is | In our data? |
|---|---|---|
| Energy charge | kWh used times a price per kWh | Yes, as the average price |
| Delivery charge | Poles, wires and meters; separate from energy in choice states | Only for Texas wires companies (EIA-861 2024) |
| Customer charge | A flat amount each month | No |
| Riders and surcharges | Programs added by the utility or state | No |
| Taxes and fees | State and local | No |
A quick estimate
Multiply your kWh by the price in cents and divide by 100. In 2025 the U.S. home average was 17.30 cents, so 900 kWh costs about $156 in energy. Fixed charges and taxes come on top.
To find your own kWh, look for the usage line on the bill, labeled kWh, usually with a bar chart of the last 12 months. Compare the same month a year ago before you compare with a neighbor.
