How Fuel Cost Calculation Works
Fuel Cost = (Distance ÷ Mileage) × Fuel PriceDistance: The total kilometers or miles you plan to travel. For round trips, use the complete journey distance (one way × 2).
Mileage: Your vehicle's fuel efficiency, measured as kilometers per liter (km/L) in India or miles per gallon (MPG) in the US and UK.
Fuel Price: The current cost of petrol or diesel per liter or gallon at your local fuel station.
Example: A 300 km trip with a vehicle giving 15 km/L mileage at ₹105 per liter = (300 ÷ 15) × 105 = 20 liters × ₹105 = ₹2,100 total fuel cost.
Practical Examples
🇮🇳 Rajesh from Bangalore
Planning a weekend trip to Mysore (150 km one way) with his Honda City giving 14 km/L mileage.
Round trip distance: 300 km | Petrol price: ₹102.50/L
Fuel needed: 300 ÷ 14 = 21.43 liters
🇮🇳 Priya from Mumbai
Daily office commute of 25 km each way on her Activa scooter with 45 km/L mileage.
Daily round trip: 50 km | Petrol price: ₹105.45/L
Fuel needed: 50 ÷ 45 = 1.11 liters
🇮🇳 Vikram from Delhi
Long-haul truck driver calculating Delhi to Jaipur (280 km) in his diesel truck getting 4 km/L.
One-way distance: 280 km | Diesel price: ₹92.30/L
Fuel needed: 280 ÷ 4 = 70 liters
🇺🇸 Michael from Texas, USA
Road trip from Dallas to Houston (240 miles) in his pickup truck getting 22 MPG.
One-way distance: 240 miles | Gas price: $3.45/gallon
Fuel needed: 240 ÷ 22 = 10.91 gallons
