Plan Your Journey

Road trips are better when the logistics are simple. This calculator helps you determine exactly how much you'll spend on gas so you can budget for the rest of your adventure. Whether you're splitting the cost with friends or just tracking your own expenses, precision helps avoid surprises at the pump.

Metric vs. Imperial

We support both standard systems. In Europe and much of the world, efficiency is measured in Liters per 100km (lower is better). In the US and UK, it's typically Miles per Gallon (higher is better).

Cost = (Distance / 100 × L/100km) × Price

Travel FAQs

How do I find my car's efficiency?

Most modern cars display 'Average Consumption' on the dashboard. You can also find your official rating on sites like FuelEconomy.gov.

Should I split costs equally?

Usually yes, but some groups prefer to have the driver pay less to account for wear and tear on their vehicle.

Does air conditioning affect trip cost?

Yes. Using AC can reduce fuel efficiency by about 5-20% depending on the outside temperature and car model.

Estimate Note

Actual fuel consumption depends on traffic, weather, altitude changes, and driving style. This tool provides a mathematical estimate based on your inputs.
