Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Battery energy added = usable capacity × charge increase. Grid energy divides by charging efficiency. Time = grid energy ÷ charger power; cost = grid energy × electricity rate.

FAQ
EV Charging Cost Calculator questions
Why is grid energy greater than battery energy?+
Charging losses occur in conversion, wiring, battery conditioning and vehicle systems.
Why can actual charging take longer?+
The vehicle may limit power or taper charging as battery temperature and state of charge change.
Does this include public charging fees?+
Only when the entered per-kWh price represents the complete charging tariff.
