Fuel Cost Calculator for Road Trips Fuel cost calculation is one formula: distance divided by fuel efficiency, multiplied by price per litre. A Mumbai-to-Goa drive (approximately 590 km) in a car achieving 14 km/L costs ₹4,214 in fuel at ₹100/litre — before tolls, food, or accommodation. --- See our Complete Guide to Financial Calculators What is The Fuel Cost Formula? Example: Delhi to Jaipur (~275 km) Vehicle: Maruti Swift (17 km/L on highway) Petrol price: ₹95/litre (Delhi 2026 average) Fuel = 275 ÷ 17 = 16.18 litres Cost = 16.18 × ₹95 = ₹1,537 For the return trip, double the fuel cost to ₹3,074. The trip fuel budget, before other expenses, is approximately ₹3,100. What is Fuel Efficiency by Vehicle Type (India, 2026)? | Vehicle Type | City km/L | Highway km/L | Example Models |…
Frequently Asked Questions
How do I calculate fuel cost for a trip?
Fuel cost = (Distance ÷ Fuel efficiency) × Fuel price per litre. For a 400 km drive in a car with 15 km/L efficiency at ₹100/litre: fuel needed = 400 ÷ 15 = 26.67 litres. Fuel cost = 26.67 × ₹100 = ₹2,667.
What is fuel efficiency and how is it measured?
Fuel efficiency measures how far a vehicle travels per unit of fuel. In India and most countries it is expressed in km/L (kilometres per litre). The UK and some others use L/100km (lower = better). The US uses MPG (miles per gallon). A car with 15 km/L consumes 6.67 litres per 100 km.
How do I convert MPG to L/100km?
L/100km = 282.5 ÷ MPG (for US gallons). A car achieving 30 MPG uses approximately 282.5 ÷ 30 = 9.4 L/100km. For km/L: km/L = MPG × 0.4251. A 30 MPG car achieves about 12.75 km/L.
How does vehicle weight affect fuel consumption?
Heavier vehicles require more energy to accelerate and maintain speed. The US Department of Energy estimates that every 100 pounds (45 kg) of extra weight reduces fuel efficiency by about 1–2%. A loaded SUV can consume 20–30% more fuel than an empty one on the same route.
How can I reduce my fuel costs?
Six proven methods: maintain correct tyre pressure (under-inflation increases consumption by 3%), drive at consistent speeds (highway fuel economy peaks at 90–100 km/h), reduce idling time, remove roof racks and cargo when not needed, ensure regular engine servicing, and use cruise control on highways.
