Electricity Cost Calculator
Estimate electricity usage and cost from appliance wattage, daily use, number of days, and your electricity rate.
How this calculator works
Appliance wattage is converted to kilowatts, multiplied by the hours used each day, then by the number of days. The result in kilowatt-hours is multiplied by your electricity rate.
Formula:
Cost = (Watts ÷ 1000) × Hours per Day × Days × Rate per kWh
