How to Calculate Fuel Cost

Fuel Cost FormulaFuel Required (L) = Distance (km) ÷ Efficiency (km/L)
Total Cost = Fuel Required × Price per Litre
Cost per KM = Total Cost ÷ Distance

Example: 500 km trip · 15 km/L · ₹105/L
Fuel = 33.33L · Cost = ₹3,500 · Per km = ₹7

Average Fuel Efficiency by Vehicle Type

VehicleFuelAvg Efficiency
Small hatchback (Maruti Alto)Petrol22–24 km/L
Mid-size sedan (Honda City)Petrol17–19 km/L
SUV (Creta, Seltos)Diesel18–20 km/L
Motorcycle (Splendor)Petrol65–70 km/L
CNG Car (Wagon R)CNG30–32 km/kg
Electric Car (Nexon EV)Electric300–350 Wh/km

Tips to Improve Fuel Efficiency

  • Maintain steady speed: Avoid rapid acceleration and sudden braking — both waste fuel significantly.
  • Correct tyre pressure: Under-inflated tyres increase rolling resistance. Check monthly.
  • Regular servicing: Clean air filters, fresh engine oil and properly gapped spark plugs improve efficiency by 5–15%.
  • Remove excess weight: Every 50 kg of extra weight reduces efficiency by approximately 2%.
  • Use AC wisely: AC increases fuel consumption by 8–15%, especially at city speeds.
