What this tool does
Charging losses mean the meter records more energy than the battery receives, typically 8–12 % more on AC charging. The calculator bills you for what comes out of the socket, which is what actually appears on the electricity bill.
Formula
cost = capacity × % load ÷ yield × price kWh
