What is Fuel Cost Calculator?
The Fuel Cost Calculator is a comprehensive tool for calculating fuel-related expenses and efficiency. It helps you estimate trip costs, determine fuel efficiency (MPG or L/100 km), calculate distances, convert units, and find how much fuel you need. Essential for road trip planning, budgeting, and tracking vehicle fuel economy.
Key Formulas
Cost = (Distance / Efficiency) × Price
Fuel = Distance / Efficiency
Distance = Fuel × Efficiency
MPG = 235.214 / (L/100 km)
1 mile = 1.60934 km • 1 gallon = 3.78541 liters
7 Calculation Types
Total Trip Cost
Enter distance, efficiency, and price. Get total fuel cost.
Cost Per Mile / km
Enter efficiency and price. Get cost per distance unit.
Fuel Efficiency
Enter distance and fuel used. Get MPG or L/100 km.
Distance
Enter fuel used and efficiency. Get distance you can travel.
Fuel Needed
Enter distance and efficiency. Get fuel needed.
Convert Units
Convert miles ↔ km and gallons ↔ liters.
Typical Fuel Efficiency
| Vehicle Type | MPG | L/100 km |
|---|---|---|
| Hybrid Car | 45 – 60 | 3.9 – 5.2 |
| Economy Car | 30 – 40 | 5.9 – 7.8 |
| SUV / Truck | 15 – 25 | 9.4 – 15.7 |
| Sports Car | 15 – 25 | 9.4 – 15.7 |
Important Notes
- All values must be positive (non-negative).
- Higher MPG = lower L/100 km = better fuel economy.
- Actual fuel economy varies with driving conditions.
- Fuel prices vary by location and over time.
