Miles Per Gallon Calculator
This calculator will compute your car's Miles Per Gallon and forecast your gasoline expense for one month and for one year. It also allows you to see how much money you would save if you were driving a car that got better gas mileage.
Once you have calculated your Current MPG you can change the Comparison MPG and the calculator will instantly recalculate the savings (click on the MPG selection box and use the down-arrow on your keyboard to quickly scroll to higher MPG comparisons).
