Electricity Consumption Calculator
Estimate appliance energy use in kWh and electricity cost from watts, hours per day, days per month, quantity and USD per kWh.
Enter your utility rate in dollars per kWh. Defaults are illustrative US-style examples.
Time-of-use mode estimates peak and shoulder energy from the non-off-peak share.
Appliance kWh and cost
