Fuel Cost Calculator

Calculate trip fuel cost from distance, efficiency, and price.

₹
Fuel-saving tips
Drive at 80–90 km/h— saves ~15% fuel vs 120 km/h
Check tyre pressure— under-inflation costs 3–5% more fuel
Remove roof racks when unused— reduces drag, saves ~5%
Use A/C sparingly— A/C adds ~10% fuel consumption

Plan your road trip budget

Knowing your fuel cost before a trip helps you budget accurately, decide whether to drive or take a train, and split costs fairly among passengers. This calculator supports one-way and return trips, all common efficiency units, and quick passenger cost-splitting.

Comparing different vehicles

Use the efficiency comparison table to see exactly how much you would save in a more fuel-efficient car. The difference between a 12 km/L SUV and a 20 km/L hatchback on a 1,000 km round trip is approximately ₹2,800 — enough to pay for a night's stay.

EV vs petrol cost comparison

An electric vehicle consuming 6 km/kWh at ₹8/unit costs ₹1.33 per km. A petrol car at 15 km/L and ₹103/L costs ₹6.87 per km — over 5× more. Over 15,000 km per year, the EV saves approximately ₹83,000 in fuel costs annually, not counting home vs public charging differences.

Frequently asked questions

How do I calculate fuel cost for a road trip?
Fuel cost = (Distance ÷ Fuel efficiency) × Fuel price per litre. For example, a 350 km trip in a car that does 15 km/L, with petrol at ₹103/L: (350 ÷ 15) × 103 = 23.33 litres × ₹103 = ₹2,403. This tool handles the calculation instantly and also shows cost per km and per-person split.
What is a good fuel efficiency for Indian cars?
Hatchbacks (Alto, WagonR): 18–22 km/L city. Sedans (City, Verna): 14–18 km/L. SUVs (Creta, Seltos): 12–16 km/L. Diesel SUVs: 15–18 km/L. Highway mileage is typically 15–20% higher than city. CNG vehicles achieve equivalent of 25–30 km per kg. EVs: 5–8 km per unit (kWh).
What is L/100km and how is it different from km/L?
km/L (kilometres per litre) — higher is better. India, UK, and most Asian countries use this. L/100km (litres per 100 kilometres) — lower is better. Europe uses this format. To convert: L/100km = 100 ÷ km/L. So 15 km/L = 6.67 L/100km. MPG (miles per gallon) is the US standard; 1 MPG ≈ 0.425 km/L.
How much does petrol and diesel cost in India?
Fuel prices vary by city and change monthly. As of mid-2025, petrol averages ₹100–107/litre and diesel ₹88–95/litre across major cities. Metro cities typically have slightly higher prices. Check your local petrol station app or the My Petrol Price website for current local rates.
How can I improve my car's fuel efficiency?
Drive at 80–90 km/h on highways (optimal for most cars). Maintain correct tyre pressure — every 10 PSI drop costs ~1% efficiency. Service air filter and spark plugs on schedule. Use engine oil of the right grade. Avoid unnecessary idling. Remove roof racks when not in use. Use cruise control on highways.
