Details

Important Assumption: The ROI calculation assumes you charge your EV 100% at home at the specified residential electricity rate. If you frequently use public DC fast chargers (which cost ₹18 to ₹25 per unit), your EV running cost per KM will increase, delaying your break-even point. Also, EVs have lower maintenance costs (no engine oil changes) which adds an extra hidden ~30% to your yearly savings!

EV vs Petrol/Diesel ROI Calculator: Is Electric Really Cheaper? (2026)

💡 Bhai Ki Advice (The EV Trap): Log sochte hain EV ka running cost ₹1/KM hai, toh EV best hai. Par sach suno! Ek average EV apni petrol counter-part se ₹3 se ₹4 Lakh mehengi aati hai. Agar aapki daily running sirf 15-20 KM hai, toh wo 4 lakh wasool karne mein aapko 8-10 saal lag jayenge, aur tab tak EV ki battery change karne ka time aa jayega (jiski cost bohot high hai). EV tabhi financially sense banati hai jab aapki daily running minimum 40-50 KM ya usse zyada ho. Is tool mein apni daily running daal kar apna ‘Asli Break-Even’ zarur check karo!

The shift to Electric Vehicles (EVs) in India is accelerating, but the biggest question for any car buyer remains: “Does the higher upfront cost of an EV justify the fuel savings?” Our EV vs Petrol/Diesel Cost Comparison Calculator uses real-world parameters like your daily running kilometers, local electricity per-unit cost, and current fuel prices to calculate your Return on Investment (ROI). We help you find your exact ‘Break-Even Point’—the exact month and year when your EV fuel savings finally cover the extra premium you paid for the car.

How to Calculate Your EV ROI & Savings

Make a smart, data-driven car buying decision by following these steps:

  1. Enter Vehicle Costs: Input the On-Road price of the EV and the exact Petrol/Diesel equivalent model (e.g., Tata Nexon EV vs Nexon Petrol).
  2. Set Your Daily Running: Estimate how many kilometers you drive daily or monthly. Pro Tip: Higher daily running dramatically speeds up your ROI.
  3. Input Fuel & Electricity Rates: Enter the current Petrol/Diesel price (₹/Liter) and your home electricity rate (₹/Unit). A standard EV consumes about 1 unit of electricity for every 7-8 kilometers.
  4. Discover Your Break-Even: The calculator will show your monthly savings and exactly how many years it will take to recover the extra upfront cost.

Frequently Asked Questions (EV vs ICE Cars)

1. What is the real-world range of EVs in India?
While ARAI claimed ranges look impressive (e.g., 400+ km), real-world EV range in Indian city traffic with the AC on is typically 25% to 30% lower than the claimed figures. Always base your calculations on the real-world range.
2. How much does it cost to replace an EV battery?
Currently, replacing a 30kWh EV battery can cost anywhere between ₹4 Lakh to ₹6 Lakh out of warranty. However, most manufacturers in India offer an 8-Year/1,60,000 KM warranty on the battery pack, providing long-term peace of mind.
3. Is EV maintenance really cheaper than petrol cars?
Yes, absolutely. EVs have far fewer moving parts. There is no engine oil to change, no spark plugs, no clutch, and no timing belts. Desi Fact: EV ki regular service mein sirf software update, AC filter check, aur brake pads inspection hota hai, jo ICE cars se bohot sasta padta hai.
4. Should I charge my EV at home or public fast chargers?
To get the maximum financial benefit, you should charge your EV at home overnight using a standard AC wall box (usually costs ₹6-₹8 per unit). Public DC fast chargers are convenient for highway trips but are 2x to 3x more expensive (₹18-₹25 per unit), which increases your running cost.
5. What is the resale value of EVs compared to petrol cars?
Currently, the resale value of EVs is slightly lower and more unpredictable compared to established petrol/diesel cars. As battery technology evolves rapidly, older EV models depreciate faster. Factor this into your 5-year ownership cost.
