How are Total Usage charges calculated?
If the item involves a per day charge, then it is calculated as follows.
Per day charge X Number of days= Total Usage Charges.
Number of days = Requested Delivery date - Return Courier dispatch date
If the item has a one time cost for entire duration then that cost is taken as the usage charge for the entire duration.
Note : Both days are included in the calculation. The days in Courier are not included for calculation of charges.
