Monthly cost = (kWh x rate) + fixed charge, then multiplied by (1 + tax%).
Yearly cost = monthly cost x 12.
US average: ~$0.16/kWh (2025). Rates vary widely by state.

Electricity bills consist of usage charges (based on kilowatt-hours consumed), fixed monthly service fees, and taxes or surcharges. The average US household uses about 900 kWh per month, but this varies significantly by region and season. Industrial and commercial facilities can use orders of magnitude more.
Comparing rates from different providers or time-of-use plans can yield significant savings. Even a $0.02/kWh difference translates to hundreds of dollars annually for a typical home.
