Common questions
- How is EV cost per kilometre calculated?
- Cost per kilometre for an EV is the electricity tariff per kWh divided by the EV efficiency in kilometres per kWh. For example, Rs 45 per kWh at 6 km per kWh gives Rs 7.50 per km.
- What does break-even mean in this calculator?
- Break-even is the time the monthly running-cost savings need to cover the extra purchase price of the EV. It is the price difference between the two cars divided by the monthly saving.
- Does this include maintenance or insurance?
- No. This calculator compares fuel and charging costs only, so the saving shown is the pure running-cost saving.
