Electric Vehicle Calculator India — FY 2025-26
Is an electric car or scooter actually cheaper than petrol? Compare the total cost of ownership over 5 years, calculate your monthly charging cost vs petrol, and find out exactly when the EV pays for itself. Includes PM E-DRIVE subsidy, home vs public charging rates, and Indian number formatting.

How to Use This Calculator
EV vs Petrol TCO tab
Select your vehicle type (scooter or car), enter the on-road prices of both EV and petrol options, your monthly distance, and holding period. The calculator computes the total cost of ownership including purchase price, fuel/charging, maintenance, insurance, and resale value. Use "More options" to fine-tune electricity rates, petrol mileage, and PM E-DRIVE subsidy.
Charging Cost tab
Enter your daily commute distance, EV efficiency (Wh/km), and electricity rate. The calculator shows your monthly EV charging cost vs petrol cost side by side. You can also specify what percentage of charging happens at public fast chargers (which cost more) vs home charging.
Break-Even Point tab
Enter the EV price premium (how much more the EV costs compared to the petrol option) and your monthly fuel saving. The calculator shows exactly how many months it takes for fuel savings to pay back the extra cost of going electric, with a year-by-year savings timeline.

The Formula
Total Cost of Ownership is calculated by summing all costs over the holding period:
TCO = Purchase Price + Fuel Cost + Maintenance + Insurance − Resale Value
EV Charging Cost:
Monthly cost = (Daily km × 26 days × Wh/km / 1000) × &rupee;/kWh
Petrol Fuel Cost:
Monthly cost = (Daily km × 26 days / km per litre) × &rupee;/litre
Break-Even (months):
Break-even = EV Price Premium / Monthly Fuel Saving
Where:
Wh/km = EV energy consumption (scooter ~30, car ~150)
26 days = approximate working days per month
Resale value accounts for higher depreciation of EVs (20-30% more than ICE)
The TCO calculation is a simplified model. Real-world costs vary based on driving patterns, electricity slab rates, actual fuel efficiency, and battery degradation over time. Road tax exemptions available in some states are not included.
Example
Rahul — Pune IT professional, comparing Ather 450X vs Honda Activa
Rahul commutes 25 km daily (round trip) in Pune. He is deciding between an Ather 450X (EV scooter, &rupee;1,40,000 on-road) and a Honda Activa (petrol, &rupee;85,000 on-road). He plans to keep the scooter for 5 years.
Step 1: Monthly fuel cost comparison
Step 2: Monthly costs
Step 3: 5-year TCO
Step 4: Break-even
For Rahul's usage, the EV scooter breaks even in under 4 years on fuel savings alone. Including lower maintenance costs, the EV becomes cheaper overall by year 5. For higher daily commutes (40+ km), EVs become clearly cheaper within 2-3 years.
