It is a calculator which helps you determine the cost of electrical energy used by your electric appliance. It is simple to use and requires you to fill in the right units in the appropriate text fields. You can begin by selecting the country of your origin. If you cannot find it on the list, then you should choose the ‘Other' option. Proceed to the typical appliance where you decide the type of electric device you would like to determine the energy cost.

The power consumption will be projected automatically upon selecting your electrical device. You have an option of choosing the units in watts or kilowatts. You can then fill the hours your device uses in a day. One Kilowatt-hour will cost twelve cents. You can also choose the currency on the right options available. Afterward, you can click on Calculate button which performs the calculations in a single click. The energy consumed per day will be filled automatically.

For example, if you are in the United States, and you are using a vacuum cleaner, its power consumption will be 1600 watts (W). Assuming that it is used for 4 hours, one Kilowatt-hour costing 12 cents, then your energy consumed per day will be 6.4 (kWh/day). Your energy costs are also projected periodically as $0.768 per day, $23.04 per month and $280.32 per year.

The procedure is simple and only requires you to select your country, the typical appliance and the number of hours used in a day. The rest of the calculations are performed by the calculator and indicated below the Calculate and Reset buttons. In case you need to determine the energy cost of another calculator, then you can use the reset button which erases everything in the text fields.

There are formulas which the calculator uses in performing the calculation.

Calculation of energy consumption
E (kWh/day) = P (W) x t (h/day) / 1000 (W/kW). It means that the energy in Kilowatt-hours is calculated by the power in watts multiplied by the number of hours’ usage, dividing the result by 1000 watts per kilowatts.

Calculation of energy cost
Cost ($/day) = E (kWh/day) x Cost (cent/kWh) / 100 (cent/$). It means that the energy cost in dollars per day is calculated by multiplying the power consumption in Kilowatt-hours per day by the energy cost of one Kilowatt-hours in (Cent / kWh) and then dividing the result by 100 cents per dollar.

The calculator is programmed to calculate the energy consumption and cost accord to your country of origin and the electrical appliance you use at home. If you want to determine the energy cost of other devices, you can always use the Reset button to remove all the text fields.
