EV Charging Cost Calculator
Estimate charging cost and ideal time.
A planning estimate, not a charging promise
Use average effective power, not a charger’s advertised peak. Cold batteries, tapering, shared power and vehicle limits affect actual time. Energy loss increases billed input energy; idle and parking fees must be added manually.
Formula & assumptions
Battery energy = capacity × (target% − start%) ÷ 100. Input energy = battery energy ÷ (1 − loss%). Cost = input energy × tariff + fees. Ideal time = battery energy ÷ effective power.
