India EV Charging Cost Calculator
Calculate monthly and annual EV charging costs using your state's DISCOM tariff, home vs public charging split, and charger type — then compare against petrol.
How this works
Charging cost = (home kWh × home tariff) + (public kWh × EVSE rate). Per-km cost = total / monthly km
Methodology
State electricity tariffs sourced from respective DISCOM published rate schedules (domestic slab ≤200 units/month). Public EVSE rates based on operator-published tariffs for ChargeZone, TATA Power EZ Charge, and Ather Grid. Monthly kWh = distance × efficiency / 1000.
