How to Calculate Gas Mileage (MPG)

Gas mileage — measured in miles per gallon (MPG) — tells you how far your vehicle travels on one gallon of gas. Knowing your gas mileage is essential for budgeting fuel costs on road trips and daily commutes.

Step-by-Step Gas Mileage Calculation

  1. 1Fill your gas tank completely and note the odometer reading
  2. 2Drive normally until you need to refuel
  3. 3Fill the tank again and note gallons added and new odometer reading
  4. 4Divide miles driven by gallons used = your MPG

Gas Mileage (MPG) = Miles Driven ÷ Gallons Used

Example: 350 miles ÷ 11.5 gallons = 30.4 MPG
