A fuel cost calculator is a practical tool that estimates how much money you will spend on fuel for a given trip or journey based on your vehicle's fuel efficiency, the distance to be covered, and the current fuel price. With petrol prices consistently above ₹100 per litre in most Indian cities, calculating fuel costs before any road trip or commute has become a standard practice for budget-conscious travellers and daily commuters alike.
Calculator Expert's Fuel Cost Calculator supports petrol, diesel, CNG, and electric vehicles. It calculates the total cost, fuel consumed in litres, cost per kilometre, and per-person share when travelling in a group — all instantly.
Petrol bikes (100–125cc): 50–70 km/L. Petrol bikes (150–200cc): 35–50 km/L. Small hatchback (petrol): 16–22 km/L. Sedan/crossover (petrol): 13–18 km/L. SUV (petrol): 10–15 km/L. Diesel hatchback: 20–26 km/L. Diesel SUV: 15–22 km/L. CNG cars: 25–32 km/kg. Electric cars: 5–8 km/kWh (very cheap to run). Fuel efficiency drops 10–20% in city traffic compared to highway.
Planning a long road trip and budgeting for fuel stops. Comparing petrol vs diesel vs CNG cost for the same journey. Calculating fair cost-sharing for carpooling. Deciding whether to rent a car or take a train based on fuel cost comparison. Fleet managers calculating monthly fuel budgets for vehicles. Delivery services estimating per-order fuel cost. Families planning annual road trips with fuel budget.
Maintain steady speed (60–80 km/h is most fuel-efficient on highways). Avoid rapid acceleration and hard braking. Keep tires properly inflated — low pressure increases fuel consumption by 3–5%. Service your vehicle regularly (clean air filter, fresh spark plugs improve efficiency). Use AC judiciously at city speeds — at highway speeds, closed windows with AC is more efficient than open windows. Carpool when possible — dividing fuel cost among 4 people saves 75% per person.
Petrol is widely available but typically 10–15% more expensive per km than diesel. Diesel vehicles cost more upfront but save money over high mileage. CNG is the cheapest fuel option (typically 40–50% cheaper per km than petrol) but refilling infrastructure is limited. Electric vehicles have the lowest per-km cost (₹1–1.5/km vs ₹5–8/km for petrol) but require home charging or charging stations. The best choice depends on your driving pattern, mileage, and available infrastructure.
Select your fuel type. Enter the trip distance and select the unit (km or miles). Enter your vehicle's fuel efficiency and select the unit. Enter the current fuel price per litre (check your local petrol station). Optionally enter number of trips and passengers. Click Calculate — the tool shows total cost, litres consumed, cost per km, and cost per person. The comparison table shows how cost changes at different fuel prices for easy planning.
Fuel prices in the reference table are approximate and change daily — always check your local petrol station for exact rates. Fuel efficiency in real-world conditions varies by 10–30% from manufacturer-stated figures depending on driving style, road conditions, AC usage, and vehicle load. Electric vehicle calculations use a simplified kWh model and may vary based on battery health and driving conditions. CNG efficiency is measured per kg, not per litre — ensure you enter price per kg when using CNG mode.
