If you are wanting to calculate your home’s kWh usage you can use this kWh calculator below to calculate kWh. This calculator uses the same kWh formula found on Formula for kWh Calculator. You may also be interested in a kWh meter to monitor certain electrical devices in your home or even your entire home. You can use a whole home kWh meter to see if your electric company is billing you for the correct amount of kWh usage.

This really sucks, I needed the amount for only 6 hours of use not 1 freaking months worth much less 1 year. It’s a cool idea but is executed atrociously and what is this ugly font???????

Gerret,
You can enter the device, watts, and 6 hours and take the total for the year and divide by 365.25 and you will get the 1 day usage for the 6 hours.

Understandable and it’s very easy to use

My monthly use is 1690 kwh per month. What size battery bank will I need?

Rob,
This is hard to say without more data, need to know total usage, max current draw, generator size, type of generator, if and how long you want your battery bank to provide power if generator fails.
