Using this calculator is simple and takes less than a minute. Follow these steps:

  1. Enter Distance (miles)
    • Input the total miles you’ll be driving. For round trips, include both ways.
  2. Enter Fuel Efficiency (MPG)
    • Check your car’s manual, fuel economy rating, or trip computer to find your vehicle’s average miles per gallon.
  3. Enter Gas Price per Gallon
    • Look up current gas prices in your area or along your travel route.
  4. Click Calculate

Example Calculation

Let’s say you’re planning a road trip from Los Angeles to Las Vegas, about 270 miles one way (540 miles round trip).

  • Distance: 540 miles
  • Fuel Efficiency (MPG): 25
  • Gas Price per Gallon: $4.20

Calculation:

  • Gas Needed = 540 ÷ 25 = 21.6 gallons
  • Trip Cost = 21.6 × 4.20 = $90.72

So, your round-trip fuel expense will be approximately $90.72.
