How it Works

This tool calculates the estimated fuel cost for a trip based on the distance, your vehicle's fuel efficiency, and the current fuel price.

Calculation Formulas:

Metric

Fuel (L) = Distance (km) × Efficiency (L/100km) ÷ 100
Cost = Fuel (L) × Price ($/L)

Imperial

Fuel (Gal) = Distance (Miles) ÷ MPG
Cost = Fuel (Gal) × Price ($/Gal)

Common Scenarios

Estimate the fuel cost for a long road trip to plan your holiday budget effectively.

🤝 Carpool Cost Splitting

Fairly split gas money with friends or colleagues for shared rides or daily commutes.

📊 Commute Analysis

FAQ

How do I find my car's MPG or L/100km?

Check your car's dashboard display for average fuel economy, or look up your car model's specifications online (EPA ratings). Real-world usage often varies, so using your own historical average is best.

What is the difference between MPG and L/100km?

L/100km measures how much fuel is obtained to drive 100 kilometers (lower is better). MPG (Miles Per Gallon) measures how far you can drive on one gallon (higher is better).

Is the calculated cost exact?

It's an estimate. Actual cost depends on traffic conditions, driving style, terrain, and weather. We recommend adding a 10-15% buffer for budgeting.

Should I include tolls in the cost?

Yes, for a complete trip cost, you should add tolls and parking fees manually. This calculator focuses strictly on fuel consumption.

Does AC affect fuel consumption?

Yes, using air conditioning can increase fuel consumption by up to 20%, especially at lower speeds or when idling.

Can I use this for electric vehicles (EVs)?

Yes, just treat "Price" as "Electricity Cost per kWh" and "Efficiency" as "kWh per 100km/miles" (adjusting the math slightly if your EV uses Wh/km).

Does speed affect MPG?

Significantly. Most cars are most efficient between 50-80 km/h (30-50 mph). Driving very fast creates more air resistance, reducing efficiency.

How can I save money on fuel?

Drive smoothly, maintain proper tire pressure, remove excess weight from the car, and use cruise control on highways to improve efficiency.
