Estimate electricity use, utility costs, solar economics, and electric vehicle charging.
Use these calculators to compare household energy costs, understand consumption, and evaluate changes such as installing solar panels or switching to an electric vehicle. The Electricity Cost Calculator estimates appliance operating costs, the Electric Bill Calculator models monthly charges, the Solar Panel Cost Calculator explores system size and installed cost, and the EV Charging Cost Calculator compares home charging with gasoline expenses.
Work out the cost of charging an electric vehicle at home, the cost per mile, and the monthly comparison against a gasoline car.
Estimate your monthly electric bill from the kilowatt-hours you use, your rate per kWh, fixed service charges, and taxes.
Estimate what any appliance or device costs to run per day, month, and year from its wattage, hours of use, and your electricity rate.
Size a home solar system from your monthly electricity use and sun hours, then estimate the installed cost before and after incentives.
Project year-one and lifetime savings, simple payback, and return on investment for a home solar system from its size, your electricity rate, and net cost.
Convert watts and hours of use into kilowatt-hours, or kilowatt-hours back into average watts, and see what that energy costs at your rate.
