About this calculator

Electric cars shift cost from the fuel pump to the meter. Whether that wins depends on the on-road premium, your annual km and the blend of home versus public charging.

This tool keeps the comparison transparent: energy maths first, then an approximate break-even against the EV premium you enter.

Formula summary

Petrol annual vs EV kWh cost; net EV premium against cumulative energy savings.

Assumptions

  • Real-world mileage is often lower than brochure ARAI figures, especially in city traffic with AC.
  • Fuel and electricity tariffs change by city and time; enter local rates.
  • Figures are approximate and for planning only.
  • Battery degradation, home charger install and public idle fees are not auto-included.

FAQs

Do I need a home charger for this to work?

Home charging usually unlocks the biggest saving. If you rely on public DC, raise the electricity rate or use the EV charging cost calculator with a higher public share.

What about FAME or state subsidies?

Reduce the EV premium input by any incentive you truly receive; policies change, so verify current schemes.
