Per-appliance daily kWh = watts × hours / 1000. Monthly cost = daily kWh × billing days × rate per kWh. US average residential rate as of May 2026 is ~$0.16/kWh (EIA), with high-cost states (HI, CA, MA, NY) at $0.30-0.45/kWh and low-cost states (LA, ID, ND) at $0.10-0.12/kWh. Central AC is typically 40-60% of summer bills in hot regions; EV charging at home adds ~$30-60/month depending on miles driven. LED bulbs use 80-90% less than incandescents.
