Electrical Consumption Calculator

The Electrical Consumption Calculator is capable of calculating the amount of electrical energy that has been consumed by the household's electric devices and, therefore, compute the total cost of using them. However, it is important to note that the cost is calculated when the price per kilowatt per hour (kWh) is has been entered.

In the list down below you can see the approximate wattage of each item. This means that this data will be used for carrying out calculations, if the user does not insert the real wattage of a particular appliance.

The wattage that is specific to a particular appliance can be typed in the "Actual" column.

If a situation occurs when the wattage of a device is unknown, then it can be figured out by applying a simple formula from physics which involved the "Volts" and "Amps" boxes. Recall, that the formula consists of multiplying the voltage by the current (Watt = Volts x Amps).

(Normally, devices have this general voltage and current information labeled on themselves, however, sometimes this information is provided in the instructions and documentation papers that go together with the appliances).

One more important advantage of the Electrical Consumption Calculator is that it can calculate both kWh and cost, daily and annually in separate boxes simultaneously. So, as long as the user inputs the necessary information, then the calculator will compute automatically the cost and the consumption per day and per year of each appliance.
