The EV Charging Cost Calculator estimates energy required and charging cost from battery capacity, charge percentage, electricity rate, and charging efficiency.

$\text{Energy from grid}=\frac{\text{Battery capacity}\times\text{Charge percentage}}{\text{Efficiency}}$ $\text{Charging cost}=\text{Grid energy}\times\text{Rate per kWh}$

Limitations

Charging losses, time-of-use rates, demand charges, battery conditioning, and station fees can change actual cost.
