Electricity Cost FAQ
Where do I find my kWh price?
It is printed on your electricity bill; the tool notes typical reference rates of about $0.17 per kWh in the US, $0.30 in the UK and $0.40 in Germany.
How do multiple devices count?
The device count multiplies daily energy directly, and the breakdown reports the total for all of them together as well as the cost per individual device per year.
What about appliances with standby power?
Measure or look up the standby draw and add a second calculation with its 24-hour usage โ a device on standby all year can still cost several dollars or more.
