Understanding Your Electricity Bill
Electricity is measured in kilowatt-hours (kWh). One kWh is the energy consumed by a 1,000-watt appliance running for one hour. Your monthly bill is calculated by multiplying total kWh consumed by your utility rate. The formula is: kWh = (Watts x Hours per Day x 30) / 1000.
