Plan Your Trip Costs
Whether you're planning a road trip or just curious about your daily commute costs, this calculator gives you an instant estimate. Enter your distance, your vehicle's fuel efficiency, and the current fuel price — done. It auto-detects your country for the right unit defaults (MPG for the US, km/L or L/100km elsewhere).
All Fuel Efficiency Formats
Different countries measure fuel efficiency differently. This calculator supports all three major formats: km/L (common in Asia, South America), L/100km (Europe, Australia), and MPG (US, UK). Mix and match — enter distance in km but efficiency in MPG if you want.
Split the Cost
Road trip with friends? Set the number of passengers and see the per-person cost instantly. Carpooling also reduces your carbon footprint — the calculator shows CO₂ estimates to put things in perspective.
Tips to Save on Fuel
- Keep tires inflated — under-inflated tires increase fuel consumption by up to 3%.
- Drive smoothly — aggressive acceleration and braking can increase fuel use by 15–30%.
- Use cruise control — maintaining a steady speed on highways saves significant fuel.
- Reduce weight — every 45 kg (100 lbs) of extra weight reduces efficiency by about 1%.
