Fuel Cost Calculator

How this fuel cost calculator works

Enter your trip distance, your vehicle's fuel efficiency, and the current fuel price. The calculator shows the total fuel needed and the total cost.

The fuel cost formula

Imperial: Cost = (Distance ÷ MPG) × Price per gallon

Metric: Cost = (Distance ÷ 100) × L/100km × Price per liter

Tips to reduce fuel costs

• Maintain proper tire pressure — underinflated tires cut MPG by 0.3% per 1 psi
• Remove excess weight — 100 lbs of cargo reduces MPG by ~1%
• Drive at 50-60 mph on highways — aerodynamic drag rises exponentially above 60
• Avoid idling — 10 minutes of idling wastes about 0.1 gallons
