What is Savings?

Saving is the portion of income not spent on current expenditures. In other words, it is the money set aside for future use and not spent immediately.

Here, cost of mattress = $ 1399

         cost of EMI = $ 78

         Duration of EMI = 18 months

         Total payable amount = 18 X 78

                                               = $ 1404

         Current account balance = $ 250

         Per month savings = $ 50

Duration at which total balance is equivalent to payable amount

                                                                                              = (1404 - 250)/50

                                                                                             = 1154/50

                                                                                             = 23.08

Thus, At least 24 times he need to deposit $ 50 to paying off his total purchase.
