The fuel cost calculator estimates how much you will spend on petrol or diesel for any trip. Enter the distance, your vehicle's fuel efficiency (mileage in km/L), and the current fuel price per litre. The calculator works for both km/L (common in India) and L/100km (common in Europe). Fuel prices in India vary by city and are revised daily by oil marketing companies.
Your actual fuel consumption depends on driving conditions. City driving with frequent stops uses 20–30% more fuel than highway driving. Air conditioning, tyre pressure, vehicle load, and driving speed also significantly affect mileage. Most petrol cars in India deliver 12–20 km/L on the highway and 8–14 km/L in city traffic.
Frequently Asked Questions
What is the current petrol price in India?
Petrol prices in India vary by city due to local taxes. As of recent data, prices range from approximately ₹94–106 per litre across major cities. Check the Indian Oil, BPCL, or HPCL app or website for today's price in your city.
How do I calculate fuel cost for a road trip?
Fuel cost = (Distance ÷ Mileage) × Fuel price per litre. For example, a 400 km trip in a car with 15 km/L mileage at ₹100/L costs (400 ÷ 15) × 100 = ₹2,667.
How can I improve my car's fuel efficiency?
Maintain correct tyre pressure, avoid aggressive acceleration and braking, drive at steady speeds (60–80 km/h is most efficient), service the engine regularly, use the recommended engine oil, and avoid excessive idling. Reducing AC use at lower speeds also helps.
Is diesel cheaper to run than petrol in India?
Diesel is priced lower than petrol in India and diesel engines are more fuel-efficient. However, diesel cars cost more upfront and maintenance is higher. Diesel is typically more economical if you drive 1,500+ km per month. For lower mileage, a petrol or CNG vehicle may be more cost-effective.
