Unit 2: Time Value of Money



            If the company needs a total of   3,00,000 on June 30, 2010, how much would it have to deposit  Notes
            every year? Here we have to solve for the rent, given the future value, as follows:
                                      FV = Rent × f (n =5, i =11%)
                                   3,00,000 = Rent × 6.22780

                     Rent =  3,00,000/6.22780 =   48,171.10
            The company has to deposit   48,171 each time in order to accumulate the necessary   3,00,0000
            by June 30, 2010.

            2.3.2  Present Value of Annuity of   1

            The present value of an annuity is the sum that must be invested today at compound interest in
            order to obtain periodic rents over some future time.

            Notice that we use the abbreviation PV for the present value of an annuity, as differentiated
            from the lower case pv for the present value of  1. By using the present value of  1, we can obtain
            a table for the present value of an  ordinary annuity of  1. The present value of an ordinary
            annuity of  1 can be illustrated as follows:
                                              Figure  2.3












            With each rent available at the end of each period, when compounding takes place, the number
            of rents is the same as the number of periods. By discounting each future event to the present, we
            find the present value of the entire annuity.

                          Present value of  1 discounted for 1 period at 8% =    0.92593
                          Present value of  1 discounted for 2 periods at 8% =  0.85734
                          Present value of  1 discounted for 3 periods at 8% = 0.79383
                          Present value of  1 discounted for 4 periods at 8% = 0.73503
                                 Present value of annuity of 4 rents at 8% =    3.31213

            The first rent is worth more than others because it is received earlier. Table on present value of
            annuities may be used to solve problems in this regard. The formula used to construct the table
            is:
                                                  1
                                             1 -
                                               (1  + i) n
                                      PV =
                                                i
                   Example: Mr. F, the owner of F Corporation is retiring and wants to use the money from
            the sale of his company to establish a retirement plan for himself. The plan is to provide an
            income of   5,00,000 per year for the rest of his life. An insurance company calculates that his life
            expectancy is 32 more years and offers an annuity that yields 9 per cent compounded annually.
            How much the insurance company wants now in exchange for the future annuity payments?
