Note that we entere the $10,000 as a postve value because t s the cash nflow you wll receve 3.5 years from now. The answer s negatve because t represents the nvestment (cash outflow) that must be mae toay. Roune to the cent, the ntal nvestment requre s $8695.61. 3 1 2 EXAMPLE 8.4B CALCULATING AN EQUIVALENT VALUE OF TWO PAYMENTS Two payments of $10,000 each must be mae one year an four years from now. If money can earn 9% compoune monthly, what sngle payment two years from now woul be equvalent to the two scheule payments? Gven: j 9% compoune monthly makng m 12 an j m 9% 12 0.75% Other ata an the soluton strategy are shown on the tmelne below. FV 1 represents the future value of the frst scheule payment an 2 represents the present value of the secon payment. 0 1 2 4 Years $10,000 $10,000 = 0.75%, n = 24 = 0.75%, n = 12 2 FV 1

2 Example Problems Solve Usng the Sharp EL-733A Calculator The sngle equvalent payment s FV 1 2. Before we start crunchng numbers, let s exercse your ntuton. Do you thnk the equvalent payment wll be greater or smaller than $20,000? It s clear that FV 1 s greater than $10,000 an that 2 s less than $10,000. When the two amounts are ae, wll the sum be more than or less than $20,000? We can answer ths queston by comparng the tme ntervals through whch we shft each of the $10,000 payments. The frst payment wll have one year s growth ae but the secon payment wll be scounte by two years growth. Therefore, 2 s farther below $10,000 than FV 1 s above $10,000. Hence, the equvalent payment wll be less than $20,000. If your calculate equvalent payment turne out to be more than $20,000, you woul know that your soluton ha an error. Returnng to the calculatons, FV 1 : 10000 0.75 12 n 0 FV Answer: 10,938.069 1 : Do not clear the values an settngs currently n memory.

EXAMPLE 8.4C CALCULATING TWO UNKNOWN LOAN PAYMENTS Kramer borrowe $4000 from George at an nterest rate of 7% compoune semannually. The loan s to be repa n three nstalments. The frst payment, $1000, s ue two years after the ate of the loan. The secon an thr payments are ue three an fve years, respectvely, after the ntal loan. Calculate the amounts of the secon an thr payments f the secon payment s to be twce the sze of the thr payment. Gven: j 7% compoune semannually makng m 2 an j m 7% 2 3.5% Let x represent the thr payment. Then the secon payment must be 2x. As ncate n the followng agram, 1, 2, an 3 represent the present values of the frst, secon, an thr payments. 0 2 3 5 Years 1 + 2 + 3 $4000 n = 4, = 3.5% $1000 n = 6, = 3.5% n = 10, = 3.5% 2x x Snce the sum of the present values of all payments equals the orgnal loan, then 1 2 3 $4000 1 : 1000 FV 4 n 3.5 0 Answer: 871.442 At frst, we may be stumpe as to how to procee for 2 an 3.

We can compute the present value of just $1 from the x ollars. 1 FV 10 n Answer: 0.7089188 The present value of $1 pa fve years from now s $0.7089188 (almost $0.71). Conser the followng questons (Q) an ther answers (A). Q: What s the present value of $2? A: It s about 2 $0.71 $1.42. Q: What s the present value of $5? A: It s about 5 $0.71 $3.55.

EXAMPLE 11.3A FINDING THE RATE OF RETURN ON FUNDS USED TO PURCHASE AN ANNUITY A lfe nsurance company avertses that $50,000 wll purchase a 20-year annuty payng $341.13 at the en of each month. What nomnal rate of return an effectve rate of return oes the annuty nvestment earn? The purchase prce of an annuty equals the present value of all payments. Hence, the rate of return on the $50,000 purchase prce s the scount rate that makes the present value of the payments equal to $50,000.
