But thereâs another value listed: how much energy you actually used. If you are a perfectly average American living in a perfectly average household, your monthly electricity bill will read 903 kilowatt hours (kWh), which costs $107, per household. But most of us donât live in perfectly average households. (The state that comes closest to matching the average monthly electricity usage is Ohio). Depending on whether a state is hot or cold, urban or rural, an average household can use as little as 531 kWh a month (Maine) or as much as 1,245 kWh (Louisiana). Costs vary state-by-state, too. Hawaiians pay the most for electricity ($203 a month) and New Mexicans pay the least ($75 a month).
