This calculator will help you to determine any savings that might occur if you were to choose a transportation alternative (walking, biking, bus ride, etc.) to driving your car. You can either compute your savings for a one-time trip or for multiple
reoccurring trips over any number of years. Plus, you can choose whether to compute the savings using the Gasoline Method (cost of gasoline only) or using the Mileage Method (average cost per mile to own, operate, maintain and insure your car).
Instructions: Enter the number of miles for the trip you are computing the savings for, enter any applicable trip costs, choose "One-time" or
"Reoccurring", choose "Gasoline Method" or "Mileage Method" and click the "Compute Savings" button. Note that you are free to change any of the default values that appear -- which are only included to serve as an example of the entry format you are required to use.
