Decision verdict
EV Strongly Recommended
Based on your 1,500 km/month driving pattern, EV becomes financially advantageous after about 27 months. Estimates exclude resale, financing, and city-specific taxes.
When an EV Might Not Be the Best Choice
EVs are not automatically the right choice for every driver. Based on usage patterns, charging access and ownership goals, petrol or CNG can sometimes be the better fit.
You Drive Less Than 500 km/Month
If your monthly driving distance is very low, fuel savings may be too small to recover the upfront EV premium during your ownership period.
No Reliable Home Charging
Drivers relying heavily on public fast charging may see reduced savings because public charging costs are usually higher than home electricity tariffs.
Planning to Keep the Vehicle for Less Than 2-3 Years
When ownership duration is shorter than the projected break-even point, petrol or CNG may be financially safer.
Frequent Long-Distance Highway Travel
Long intercity journeys may require additional charging stops and can reduce real-world EV efficiency at sustained highway speeds.
✅ Your Usage Pattern Supports EV Ownership
These are planning considerations only and should be combined with factors like resale value, vehicle availability, charging infrastructure and personal driving needs.

Fuel spend option
SBI BPCL Octane Credit Card
You're spending approximately ₹1,34,935/year on petrol. Fuel reward cards may help offset some of these costs. The card advertises up to 7.25% value back on eligible BPCL petrol purchases; actual rewards, caps and fees depend on issuer terms.

EV financing
Check SBI Green Car Loan terms
Your usage pattern makes EV economics attractive. Some promotions may advertise a 0.50% interest concession; confirm current availability, its basis, eligibility and total loan cost directly with the lender.

Compare motor insurance cover
Review coverage, exclusions and premiums for your chosen vehicle. EV owners should confirm battery protection and exclusions with the insurer in writing.

Explore rooftop solar for home charging
Home charging users may further reduce charging costs with rooftop solar. Check current central and state scheme eligibility, installation costs and export rules before making a decision.
Review rooftop solar schemeEnergy and efficiency inputs
Reference prices: petrol ₹105/L, CNG ₹83/kg, home electricity ₹8/kWh and public DC charging ₹22/kWh.
Baseline efficiencies are reduced by 18%: petrol 17 to 13.94 km/L; CNG 24 to 19.68 km/kg; EV 8 to 6.56 km/kWh.
EV charging blend used: 80% home / 20% public at an effective ₹10.80/kWh.
Ownership and break-even method
Annual ownership outflow = (monthly distance × cost/km × 12) + annual overhead. Modeled overhead: petrol ₹12,000, CNG ₹14,500 and EV ₹5,500 per year.
Variant premiums over petrol: CNG ₹1,00,000 and EV ₹2,50,000. Break-even months = premium ÷ annual petrol-versus-option outflow difference × 12.
The overhead is a blended placeholder for insurance risk, servicing and tyre wear; the CNG figure includes a hydro-testing allowance. Loan interest differentials, actual insurance quotes, resale, depreciation and taxes are not included because no defensible values were supplied.
Why Simple Distance-to-Fuel Equations Fail in Indian Stop-and-Go Traffic
ARAI test-cycle efficiency is measured under standardized conditions, not every owner's route. Congestion, idling, short trips, gradients, tyre pressure, vehicle load and summer air-conditioning can widen the gap between a laboratory claim and real Indian city consumption. The 18% correction here is a planning assumption, not a guarantee for a specific model.
EV range and energy use can also shift with cabin cooling, fast-charging patterns and high ambient temperatures. Battery capacity changes gradually with age and use; chemistry, thermal management and charging habits affect degradation, so a single fixed percentage would imply more certainty than this calculator has.
CNG cylinder inspection and testing should follow the applicable vehicle and PESO safety requirements and an authorized testing schedule. The Indian Stamp Act is not the governing cylinder-testing rule. Confirm requirements with the vehicle manufacturer, authorized test centre and relevant transport authority.
Planning estimate only, not financial, lending, insurance or vehicle-purchase advice. Fuel tariffs, reward rates, loan offers and rules can change; verify current terms with the relevant provider.
Frequently Asked Questions
Answers update with the distance, charging and ownership inputs above.
Is EV cheaper than petrol in India?
₹1.65/km for the modeled EV versus ₹7.50/km for petrol. Over 5 years at your current distance, EV has the lowest estimated total ownership cost (₹4,25,671).
How many kilometers are needed to recover EV cost?
Estimated EV break-even is about 27 months, or roughly 40,250 km at your current monthly distance.
What is EV running cost per km?
The current estimate is ₹1.65/km, using an 80% home and 20% public charging blend and the modeled real-world efficiency.
Petrol vs CNG: which is cheaper?
CNG is estimated at ₹4.19/km compared with petrol at ₹7.50/km. The 5-year total including modeled premium and overhead is ₹5,49,787 for CNG and ₹7,34,677 for petrol.
Is an EV worth buying for daily commuting?
Based on your 1,500 km/month driving pattern, EV becomes financially advantageous after about 27 months. The estimate uses 1,500 km of monthly travel; actual suitability also depends on charging access, route, resale, financing and local tariffs.
How does home charging affect EV costs?
With home charging enabled, the model assumes 80% home electricity at ₹8/kWh and 20% public charging at ₹22/kWh, producing an effective tariff of ₹10.80/kWh and estimated EV energy cost of ₹1.65/km.
These estimates use real-world correction factors and planning assumptions. Actual costs vary by city, driving style, electricity tariff, policy changes, financing terms, maintenance, and resale value.
