How does the electricity cost calculator work?

It's rather simple. If you know the value for power consumption, energy price and usage time, the calculator will automatically display how much power you consume per day and generate the exact annual price for electricity. You can also change the units at will (for example change days to months or watts to kilowatts).

Energy cost calculation

The energy cost per day in dollars is equal to the energy consumption E in kWh per day times the energy cost of 1 kWh in cents/kWh divided by 100 cents per dollar:

Cost_($/day) = E_(kWh/day) × Cost_(cent/kWh) / 100_(cent/$)
