What is an Electricity Bill Calculator?
An electricity bill calculator estimates your monthly electric costs based on the appliances you use, their wattage, and how many hours they run. Understanding what consumes the most electricity helps you reduce your bills and make smarter energy choices.
Your electricity bill is calculated in kilowatt-hours (kWh)—the amount of energy used. A 1000-watt device running for 1 hour uses 1 kWh. The average US rate is about $0.12-0.15 per kWh, but it varies significantly by state and utility company.
