How is daily rental billing calculated?

Rentals are billed based on a 24-hour clock. If you return the rental within 24 hours or less, you will be charged for one day. Fleet Services allows a grace period of 1 hour. The 26th hour will be billed at 1/3 of the daily rate, the 27th hour will be billed at 2/3 of the daily rate. Subsequent hours will result in a full day charge. For example, if you check out a vehicle at 8am on Monday and return the vehicle at 4pm on Tuesday, you will be charged 2 rental days. Another example would be if you checked out a vehicle at 8am on Monday and returned it at 10am on Tuesday, you would be charged 1.33 rental days.
