Monthly electricity cost calculator
Pick your state, enter monthly kWh usage, and see an estimated electricity cost using each state's residential all-in average electricity rate.
Estimated monthly electricity cost: $164.79
Rate applied: 18.31 ¢/kWh
Depending on the state, roughly 23–68% of a typical bill is delivery, riders, fees, and taxes — see what's inside the all-in rate.

Fees are already included: this uses the all-in average rate — energy, delivery, and utility fees together, not just the electricity.
The calculator above starts at the U.S. average rate — switch to your state for a local monthly electric bill estimate from kWh × residential electricity rate. For a specific kWh amount (any number, not just common tiers), use the kWh cost calculator. Further down you'll find links to state calculators, fixed usage examples, appliance tools, and related guides.
Rates come from the same U.S. Energy Information Administration residential dataset used across this site's state pages, average bill comparisons, usage-cost examples, and appliance calculators.
What electricity costs by kWh at the U.S. average rate
Every row is kWh × 18.31 ¢/kWh, the U.S. average all-in residential rate — delivery, fixed fees, and utility charges are already inside it. If a value is your monthly usage, the cost shown is a monthly supply estimate; state rates run from 12.72 ¢/kWh to 48.00 ¢/kWh, so use the calculator above for your state's number.

How electricity cost is calculated
Monthly electric bill estimate = monthly kWh usage × state electricity rate (in dollars per kWh). That means the same home usage can produce very different bill outcomes as you move between states.
For common search scenarios, we also publish fixed usage examples (by kWh tier) and state-specific pages; those deeper pages live under the electricity usage cost section.
State electricity cost calculators
Each card shows the state's cost per kWh and the bill per month at 900 kWh. Every state calculator links onward to average bill pages, price-per-kWh pages, usage-tier pages, trend pages, appliance calculators, and appliance cost-to-run pages.
