Frequently Asked Questions
How is electricity cost calculated?
Electricity cost = (Watts ÷ 1000) × Hours × Price per kWh. Example: A 1,500W space heater running 8 hours/day at \$0.13/kWh costs: (1500 ÷ 1000) × 8 × 0.13 = \$1.56/day or about \$47/month.
What is a kilowatt-hour (kWh)?
One kilowatt-hour is the energy used by a 1,000-watt device running for one hour. It is the unit used by utility companies to measure and bill electricity. The average US household uses about 900 kWh per month.
