Formula Used

Gallons of fuel needed = Distance (miles) ÷ Fuel efficiency (MPG)

Total Cost Calculation

Total cost = Gallons of fuel needed × Price per gallon

Cost per Mile Calculation

Cost per mile = Total cost ÷ Distance (miles)

These formulas provide a straightforward way to estimate your fuel expenses. Keep in mind that real-world factors like traffic conditions and driving habits may affect your actual results.

Worked Example

Let's say you're planning a 300-mile road trip with a car that gets 25 miles per gallon, and the current gasoline price is $3.50 per gallon.

  1. Gallons needed: 300 miles ÷ 25 MPG = 12 gallons
  2. Total cost: 12 gallons × $3.50 = $42
  3. Cost per mile: $42 ÷ 300 miles = $0.14 per mile

This example shows that for this trip, you would need 12 gallons of fuel, costing $42 in total, or $0.14 per mile.
