5. 4-5 Rs. 10,000 today Obviously, Rs. 10,000 today. TIME VALUE TO MONEY You already recognize that there is TIME VALUE TO MONEY!! The Interest Rate Rs. 10,000 today Rs. 10,000 in 5 years Which would you prefer – Rs. 10,000 today or Rs. 10,000 in 5 years?

6. 4-6 The worth or value of MONEY at different points in time is “Time value of Money” Time Value of Money TIME Why is TIME such an important element in your decision?

7. 4-7 Types of Interest Compound Interest Compound Interest Interest paid (earned) on any previous interest earned, as well as on the principal borrowed (lent). u Simple Interest Interest paid (earned) on only the original amount, or principal borrowed (lent).

8. 4-8 Simple Interest We require: Value:Simple Interest PV:Deposit today (t=0) i:Interest Rate per Period n:Number of Time Periods Two types of Values: Present Value Future Value

9. 4-9 Future Value (FV) FV is the value at some future time of a present amount of money, or a series of payments, evaluated at a given interest rate. Compounding The process of going from today’s value to future values is called Compounding FV = PV (1 + i)ⁿ FV = PV (1 + i)ⁿ FV = Future Value PV= Present Value i= interest rate n = No of years

10. 4-10 FV Example Assume that you deposit Rs.1,000 in an account earning 7% simple interest for 2 years. What is the accumulated interest at the end of the 2nd year? FV = PV (1 + i)ⁿ FV = PV (1 + i)ⁿ

11. 4-11 Rs.1,000 2 years Assume that you deposit Rs.1,000 at a compound interest rate of 7% for 2 years. Future Value Single Deposit (Graphic) 2 0 1 2 Rs.1,000 FV 2 7%

12. 4-12 Why Compound Interest? Future Value (U.S. Dollars)

13. 4-13 FV 1 PVRs.1,000 Rs.1,070 FV 1 = PV(1+i) 1 = Rs.1,000 (1.07) = Rs.1,070 Compound Interest You earned Rs.70 interest on your Rs.1,000 deposit over the first year. This is the same amount of interest you would earn under simple interest. Future Value Single Deposit (Formula)

14. 4-14 FV 1 PVRs.1,000 Rs.1,070 FV 1 = PV(1+i) 1 = Rs.1,000 (1.07) = Rs.1,070 FV 2 PV Rs.1,000 PVRs.1,000 Rs.1,144.90 FV 2 = FV 1 (1+i) 1 = PV (1+i)(1+i) = Rs.1,000(1.07)(1.07) = PV(1+i) 2 = Rs.1,000(1.07) 2 = Rs.1,144.90 Rs.4.90 You earned an EXTRA Rs.4.90 in Year 2 with compound over simple interest.

15. 4-15 FV 1 FV 1 = PV(1+i) 1 FV 2 FV 2 = PV(1+i) 2 Future Value General Future Value Formula: FV n FV n = PV(1+i) n FV n FVIF or FV n = PV(FVIF i,n ) General Future Value Formula etc.

16. 4-16 FVIF FVIF i,n Valuation Using Table 1.145

17. 4-17 FV 2 FVIF Rs.1,145 FV 2 = Rs.1,000 (FVIF 7%,2 ) = Rs.1,000 (1.145) = Rs.1,145 [Due to Rounding] Using Future Value Tables

18. 4-18 Rs.10,000 5 years Julie Miller wants to know how large her deposit of Rs.10,000 today will become at a compound annual interest rate of 10% for 5 years. Problem Example 5 0 1 2 3 4 5 Rs.10,000 FV 5 10%

19. 4-19 FV 5 FVIF Calculation based on Table: FV 5 = Rs.10,000 (FVIF 10%, 5 ) Story Problem Solution FV n FV 5 u Calculation based on general formula: FV n = PV(1+i) n FV 5 =

20. 4-20 Present Value (PV) PV is the current value of a future amount of money, or a series of payments, evaluated at a given interest rate Discounting The process of finding future values is called Discounting PV = FV (1 + i)⁻ⁿ PV = FV (1 + i)⁻ⁿ FV = Future Value PV= Present Value i= interest rate n = No of years

21. 4-21 Present Value (PV) Rs. 1,000 2 years. Assume that you need Rs. 1,000 in 2 years. Let’s examine the process to determine how much you need to deposit today at a discount rate of 7% compounded annually. PV = FV (1 + i)⁻ⁿ PV = FV (1 + i)⁻ⁿ
