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
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
| Vehicle | Fuel | Avg Efficiency |
|---|---|---|
| Small hatchback (Maruti Alto) | Petrol | 22–24 km/L |
| Mid-size sedan (Honda City) | Petrol | 17–19 km/L |
| SUV (Creta, Seltos) | Diesel | 18–20 km/L |
| Motorcycle (Splendor) | Petrol | 65–70 km/L |
| CNG Car (Wagon R) | CNG | 30–32 km/kg |
| Electric Car (Nexon EV) | Electric | 300–350 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.
Frequently Asked Questions
We multiply the trip distance by your vehicle's fuel consumption rate, then multiply the total liters used by the local fuel price.
Fuel efficiency measures how far a vehicle can travel on a set amount of fuel (e.g., kilometers per liter, or miles per gallon).
Yes, the calculator allows you to enter the number of passengers to split the total fuel cost equally.
