About this calculator
Diesel’s efficiency advantage only matters if you actually drive enough kilometres before you sell. This calculator frames that trade-off in rupees and years.
Enter the on-road premium for diesel, both mileages and local fuel prices. The net after premium is indicative — maintenance and resale can still swing the decision.
Formula summary
Annual fuel each = (km ÷ mileage) × price; savings vs diesel premium → break-even years.
Assumptions
- Real-world mileage is often lower than brochure ARAI figures, especially in city traffic with AC.
- Fuel and electricity tariffs change by city and time; enter local rates.
- Figures are approximate and for planning only.
- Ignores diesel AMC differences, AdBlue and resale unless you adjust the premium.
