How to use this tool#
To find out the energy cost:
- Enter the cost of 1 kWh of electric energy. This is exact price of energy you pay every month to you electric energy provider.
The best way to find the real energy cost: try finding your last energy invoice and find the "price for 1 kWh".
- Specify all electric devices
You can click on "Click here to add one simple device" in the calculator - then enter the nominal electric power of the device, and the average time that this device is turned on every day.
You can also use some shorcuts below - we prepared a list of frequently used devices in a typical household. Just click "washing machine", and the typical washing machine will be added. Of course, you can adjust the power consumption and time of daily usage for the particular device.
- The results #1 - in the table, next to the specified devices, you can find the cost and the energy usage by daily, montly and annual scale.
- The results #2 - below the "shortcut devices", you can find the resulting table in a more "compact" format. This also displays costs by year, month and day usage.
- results #1 and results #2 are the computed the same way, the only difference is they are displayed in a different manner.
