Frequently Asked Questions
Is an EV really cheaper than petrol cars?
Per-kilometer cost of EVs is typically 40-60% cheaper than petrol cars. However, factors like higher upfront cost, battery replacement, and driving patterns affect total cost of ownership. This calculator focuses on fuel/electricity costs only.
What fuel consumption values should I use?
For petrol cars: typical sedans get 12-16 km/l, SUVs get 8-12 km/l. For accurate values, check your vehicle's specifications. Current petrol prices vary by location; use your local rates.
How do I find EV efficiency (km per ₹)?
Check your EV's energy consumption (kWh per 100 km) and divide by local electricity rate. For example: if consumption is 15 kWh per 100 km with electricity at ₹8/kWh, cost is ₹1.2 per km, so efficiency is about 0.83 km per rupee.
Should I include battery replacement cost?
Battery replacement is a major cost for EVs (₹3-8 lakhs). This calculator focuses on fuel costs. For total cost of ownership, add battery replacement amortized over the years.
What other costs should I consider?
