What is the per mile charge?

The per mile charge is a charge included by the rental car companies to earn money for each mile you drive the vehicle. Some companies offer a free number of miles and then each additional mile you drive is on a per mile charge. This per mile charge is basically the amount you have to pay for each mile you drive the vehicle. For example, some companies offer $0.25 a mile. So when you rent the car, for each mile that you drive, you have to pay $0.25. This can turn out to be fairly expensive for long road trips. It is wise to look for packages that offer a number of free miles. This will help reduce the rental costs.
