Home Energy Use Calculator
Estimate monthly kWh and cost from common household appliances and your own devices.
How it is calculated
Daily energy (kWh) = watts × quantity × hours ÷ 1,000. Monthly energy = daily energy × days. Cost = monthly kWh × your rate.
Results are estimates for planning, not bills or professional advice. For generator hookups use a transfer switch installed by a licensed electrician.
