About the Fuel Cost Calculator

Estimate how much fuel a trip will use and what it will cost, based on distance, your vehicle's fuel efficiency, and the price of fuel.

  2. Enter your vehicle's fuel efficiency (MPG or L/100km).
  3. Enter the price per gallon or liter.
  4. Press Calculate to see the fuel needed and total trip cost.

Tips for the Fuel Cost Calculator

  • Highway driving typically gets better MPG than city driving — use a figure close to how you'll actually be driving for a more accurate estimate.

Formula used by the Fuel Cost Calculator

Fuel needed = Distance ÷ MPG Total cost = Fuel needed × Price per gallon

Example: Fuel Cost Calculator

A 300-mile road trip at 28 MPG with gas at an illustrative $3.50/gallon

  • Distance: 300 miles
  • Fuel efficiency: 28 MPG
  • Price per gallon: $3.50 (illustrative)

Result: Fuel needed 10.71 gallons — total cost ≈ $37.50

Fuel needed = 300 ÷ 28 ≈ 10.71 gallons; total cost = 10.71 × $3.50 ≈ $37.50.
