Fuel Consumption Calculator: Calculate Trip Fuel Cost

Planning a road trip or regularly commuting? Knowing your vehicle's fuel consumption and calculating trip costs helps budget effectively and compare different routes or vehicle options. Our Fuel Consumption Calculator computes fuel needed for any journey and the associated cost at current fuel prices.

Fuel Efficiency Metrics

India uses km/L (kilometers per liter) as the primary efficiency measure. ARAI (Automotive Research Association of India) certifies official mileage under controlled conditions. Real-world mileage is typically 15-25% lower than ARAI figures due to traffic conditions, driving style, AC usage, and load. Always use your actual measured mileage for accurate trip calculations, not manufacturer claims.

Trip Fuel Calculation

Fuel needed (liters) = Trip distance (km) ÷ Fuel efficiency (km/L). Fuel cost = Fuel needed × Price per liter.

Example: Mumbai to Pune (150 km) in a car averaging 15 km/L at ₹105/L. Fuel = 150 ÷ 15 = 10 liters. Cost = 10 × ₹105 = ₹1,050 one-way, ₹2,100 round-trip.

Comparing Vehicles for a Route

CNG vehicle at 25 km/kg and CNG at ₹90/kg vs. petrol at 15 km/L and petrol at ₹105/L for the same 150 km route. CNG: 150÷25 = 6 kg × ₹90 = ₹540. Petrol: ₹1,050. CNG saves ₹510 per trip — significant for daily commuters covering 50-100 km/day.

Fuel Cost Per KM

Running cost per km = Fuel price ÷ Fuel efficiency. At 15 km/L and ₹105/L: ₹7/km. At 20 km/L and ₹105/L: ₹5.25/km. This metric is useful for comparing true operating costs of different vehicles and calculating accurate expense reimbursements.
