See how much you would save on fuel by switching from one car to a more efficient one. Enter the MPG of your current car and the car you are considering, along with your yearly mileage and the price of fuel. This calculator shows the annual fuel cost of each car, the yearly saving, and the total saving over five years, which is often the number that decides whether a more efficient car is worth a higher price. Small MPG differences add up fast at high mileage, and the savings are not linear because fuel cost depends on the inverse of economy. That is why going from 20 to 25 MPG saves more fuel than going from 40 to 45. All calculations run locally in your browser and nothing you enter is stored or sent.
