Calculate trip fuel costs, compare vehicles, estimate monthly expenses & track mileage. Plan trips with fuel stops, cost sharing & CO₂ emissions tracking. Free fuel calculator with multi-currency support.
Calculate fuel cost for a single journey
Pro Tip: The calculator supports multiple currencies (₹, $, €, £) and units (km/miles, km/L/MPG/L/100km). All calculations update in real-time as you adjust values.
Fuel efficiency measures how far your vehicle travels per unit of fuel consumed. It's expressed in different units globally: km/L (kilometers per liter) in India and Asia, MPG (miles per gallon) in the US, and L/100km (liters per 100 kilometers) in Europe. Higher km/L or MPG means better efficiency, while lower L/100km indicates better performance.
The basic fuel cost formula is: Fuel Cost = (Distance ÷ Fuel Efficiency) × Fuel Price. For example, if you drive 100 km with 15 km/L efficiency and fuel costs ₹100/L, you'll need 6.67 liters costing ₹667. Our calculator handles all unit conversions automatically.
Common in India, Asia. Higher is better. Typical range: 10-25 km/L for cars.
Used in USA. Higher is better. Typical range: 20-40 MPG for cars.
European standard. Lower is better. Typical range: 4-10 L/100km for cars.
Proper trip planning helps avoid fuel emergencies and saves money. Our trip planner calculates total fuel needed, number of refueling stops, and cost per passenger for shared trips. Always plan fuel stops before entering remote areas.
Understanding your monthly and yearly fuel costs helps with financial planning. Track your daily commute distance and driving frequency to get accurate estimates. Our calculator provides both monthly and annual projections based on your driving patterns.
Monthly Cost = (Daily Distance × Days per Week × 4.33 × Fuel Price) ÷ Fuel Efficiency
Yearly Cost = Monthly Cost × 12
The 4.33 factor represents average weeks per month (52 weeks ÷ 12 months).
When buying a new vehicle or comparing your current car with alternatives, fuel cost comparison is crucial. A vehicle with better fuel efficiency may have higher upfront cost but saves money long-term. Our comparison tool shows exact savings and percentage difference.
When comparing vehicles with different purchase prices, calculate break-even point: Break-Even Distance = Price Difference ÷ (Cost per km of Vehicle 1 - Cost per km of Vehicle 2). If you drive more than this distance, the fuel-efficient vehicle saves money overall.
Every liter of fuel burned produces approximately 2.31 kg of CO₂ (petrol) or 2.68 kg (diesel). Our calculator tracks your carbon footprint, helping you understand environmental impact. Reducing fuel consumption directly reduces emissions.
Hybrid/Electric vehicles, efficient driving, regular maintenance
Target: <100g CO₂/km
Average cars with normal driving patterns
Range: 100-150g CO₂/km
SUVs, poor maintenance, aggressive driving
Above: >150g CO₂/km
To calculate fuel cost: (1) Divide trip distance by your vehicle's fuel efficiency to get liters needed, (2) Multiply liters by fuel price per liter. Formula: Fuel Cost = (Distance ÷ Efficiency) × Price. For example, 200 km trip with 15 km/L efficiency at ₹100/L costs ₹1,333. The calculator supports multiple units (km/miles, km/L/MPG/L/100km) for instant calculations.
Good fuel efficiency varies by vehicle type: Small cars: 18-25 km/L (42-59 MPG),Sedans: 15-20 km/L (35-47 MPG), SUVs: 10-15 km/L (24-35 MPG),Trucks: 8-12 km/L (19-28 MPG). Hybrid vehicles achieve 20-30 km/L (47-70 MPG). Electric vehicles measure efficiency in km/kWh instead. Higher numbers indicate better efficiency and lower fuel costs.
Reduce fuel costs by: Driving habits - smooth acceleration, steady speed, avoid idling.Maintenance - proper tire pressure (+3-5% efficiency), regular service, clean air filter.Vehicle choice - fuel-efficient model, right size for needs. Trip planning - combine errands, avoid traffic, shortest routes. Weight reduction - remove unnecessary items.Speed management - optimal 50-80 km/h. AC usage - use wisely. These strategies can reduce fuel costs by 20-40%.
