Fuel-cost and break-even calculator
A lower fuel bill only offsets a higher purchase price if you drive enough. Enter your costs and distance to see whether the premium pays back during your ownership.
Start with a hypothetical scenario, then replace every assumption with your own. Compare equally equipped cars using the same purchase-price basis.
Your fuel-only result
- Petrol energy cost
- ₹6.67/km
- Alternative energy cost
- ₹4.00/km
Break-even: 56,250 km, or about 56.2 months. Within your ownership period.
Over 5 years: petrol energy ₹4,00,000; alternative energy ₹2,40,000.
Net saving after premium: ₹10,000
Includes the extra purchase cost and energy only. Excludes finance, service, insurance differences, charger installation and resale. Zero purchase premium with positive savings breaks even immediately.
How is break-even calculated?
Energy cost per kilometre is energy price divided by mileage. For an EV, battery efficiency is also adjusted for grid-to-battery charging losses. For CNG, we use the same 90% CNG / 10% petrol-distance allowance as the catalogue.
Break-even distance = extra purchase cost ÷ saving per kilometre. Break-even months = distance ÷ monthly driving. No positive saving means there is no fuel-saving break-even; no driving means the premium cannot be recovered through driving.
A hypothetical example
A ₹1,50,000 premium and ₹3/km saving need 50,000 km to recover. At 1,000 km per month, that is 50 months. These are illustrative numbers, not a manufacturer claim or live fuel-price quote.
What should I include in my decision?
Use comparable on-road purchase costs for equally equipped variants, your expected real-world mileage and local energy prices. This fuel-only tool excludes financing, maintenance, insurance differences, resale and charger installation. Public charging, refuelling access and luggage needs also matter.
