Fuel Calculator
Plan your road trip budget with our fuel cost calculator. Simply enter your trip distance, vehicle fuel economy, and current gas price to see exactly how much your journey will cost in fuel.
How to Calculate Fuel Cost
Calculating fuel cost for a trip is straightforward: divide your total distance by your vehicle's fuel economy (MPG) to find gallons needed, then multiply by the price per gallon. Our calculator does this automatically and also shows your cost per mile.
The formula is: Total Cost = (Distance ÷ MPG) × Price per Gallon. For example, a 300-mile trip in a car that gets 25 MPG at $3.50/gallon costs: (300 ÷ 25) × $3.50 = $42.00.
Understanding fuel costs helps you budget for travel, compare vehicle efficiency, and make informed decisions about transportation options.

Tips to Improve Fuel Efficiency
- ✓
Drive Steadily: Maintain a consistent speed and use cruise control on highways. Rapid acceleration and braking waste fuel.
- ✓
Reduce Speed: Fuel efficiency drops significantly above 50 mph. Driving at 55 mph instead of 65 can improve fuel economy by 10-15%.
- ✓
Remove Excess Weight: Extra weight reduces fuel economy. Remove roof racks and unnecessary items from your vehicle.
- ✓
Maintain Your Vehicle: Regular oil changes, air filter replacements, and proper tire pressure keep your car running efficiently.
