How Electricity Costs Are Calculated
Electricity is measured in kilowatt-hours (kWh). To find daily usage, multiply the appliance wattage by hours used, then divide by 1,000. Multiply by your rate per kWh to get the cost. The US national average rate is approximately $0.16/kWh (2025), but rates vary significantly by state, from $0.10/kWh in Louisiana to $0.43/kWh in Hawaii.
