About This Fuel Cost Calculator
Calculate how much fuel you'll need and what it will cost for any trip. Supports metric (L/100km) and imperial (mpg) efficiency ratings, and both liters and gallons for pricing. The result is unitless — enter your local fuel price and get your cost in the same currency.
Tips to Reduce Fuel Costs
- Maintain steady speed — aggressive acceleration and braking wastes 20–30% more fuel.
- Keep tires properly inflated — underinflation increases consumption by up to 3%.
- Reduce weight — remove unnecessary cargo from the trunk.
- Use cruise control on highways to maintain optimal speed.
- Plan routes to avoid traffic, since idling burns fuel with zero mileage.
Frequently Asked Questions
What does L/100km mean?
Liters per 100 kilometers (L/100km) is the standard fuel efficiency metric in most countries. It tells you how many liters of fuel are consumed for every 100 km traveled. Lower is better — a car using 6L/100km is more efficient than one using 12L/100km.
How do I convert mpg to L/100km?
Divide 235.21 by your mpg value. For example, 30 mpg = 235.21 / 30 ≈ 7.84 L/100km. This calculator handles the conversion automatically.
Does the calculator account for city vs highway driving?
No — it uses a single efficiency value. For mixed driving, use the combined fuel efficiency rating from your vehicle's specifications. City driving typically uses 20–40% more fuel than highway driving.
Typical Efficiencies
- Small car: 6–9 L/100km
- Mid-size car: 9–12 L/100km
- SUV/Truck: 12–18 L/100km
- Hybrid: 4–6 L/100km
- Electric: ~2 kWh/10km
