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.
