This document discusses concepts related to the time value of money, including present and future value calculations. It covers key topics like compound interest, discounting cash flows, loan amortization schedules, and the internal rate of return. Examples are provided to illustrate how to use formulas to calculate future values, present values, loan payments, and identify the internal rate of return for an investment project. The goal is to understand how to adjust cash flows for differences in timing and risk.
Time value concepts
- 1. Concepts of Value and ReturnCHAPTE R 2 Faculty: Ahamed Riaz
- 2. LEARNING OBJECTIVES Understand what gives money its time value. Explain the methods of calculating present and future values. Highlight the use of present value technique (discounting) in financial decisions. Introduce the concept of internal rate of return. 2
- 3. Time Preference for Money Time preference for money is an individual’s preference for possession of a given amount of money now, rather than the same amount at some future time. Three reasons may be attributed to the individual’s time preference for money: risk preference for consumption investment opportunities 3
- 4. Required Rate of Return The time preference for money is generally expressed by an interest rate. This rate will be positive even in the absence of any risk. It may be therefore called the risk-free rate. An investor requires compensation for assuming risk, which is called risk premium. The investor’s required rate of return is: Risk-free rate + Risk premium. 4
- 5. Required Rate of Return Would an investor want Rs. 100 today or after one year? Cash flows occurring in different time periods are not comparable. It is necessary to adjust cash flows for their differences in timing and risk. Example : If preference rate =10 percent An investor can invest if Rs. 100 if he is offered Rs 110 after one year. Rs 110 is the future value of Rs 100 today at 10% interest rate. Also, Rs 100 today is the present value of Rs 110 after a year at 10% interest rate. If the investor gets less than Rs. 110 then he will not invest. Anything above Rs. 110 is favourable. 5
- 6. Time Value Adjustment Two most common methods of adjusting cash flows for time value of money: Compounding—the process of calculating future values of cash flows and Discounting—the process of calculating present values of cash flows. 6
- 7. Future Value Compounding is the process of finding the future values of cash flows by applying the concept of compound interest. Compound interest is the interest that is received on the original amount (principal) as well as on any interest earned but not withdrawn during earlier periods. Simple interest is the interest that is calculated only on the original amount (principal), and thus, no compounding of interest takes place. 7
- 9. Future Value In Microsoft Excel: Use FV function. FV(rate,nper,pmt,pv,type) Where: rate= interest rate. nper= n periods, pmt= annuity value, pv= present value, type= 1 for beginning of the period and 0 for end for end of period. 9

- 15. Present Value Present value of a future cash flow (inflow or outflow) is the amount of current cash that is of equivalent value to the decision-maker. Discounting is the process of determining present value of a series of future cash flows. The interest rate used for discounting cash flows is also called the discount rate. 15

- 20. Capital Recovery and Loan Amortisation20
- 21. Loan Amortisation Schedule 21 End Payment Interest Principal Outstanding ofYear Repayment Balance 0 10,000 1 3,951 900 3,051 6,949 2 3,951 625 3,326 3,623 3 3,951 326 3,625* 0
- 22. Present Value of an Uneven Periodic Sum In most instances the firm receives a stream of uneven cash flows. Thus the present value factors for an annuity cannot be used. The procedure is to calculate the present value of each cash flow and aggregate all present values. 22
- 23. PV of Uneven Cash Flows: Example23
- 24. Present Value of Perpetuity 24
- 25. Present Value of a Perpetuity: Example25
- 26. Present Value of Growing Annuities26
- 27. Example 27
- 28. Example 28
- 29. Value of an Annuity Due 29
- 30. Future Value of An Annuity: Example30
- 31. Example The present value of Re 1 paid at the beginning of each year for 4 years is 1 × 3.170 × 1.10 = Rs 3.487 31
- 36. Present Value and Rate of Return A bond that pays some specified amount in future (without periodic interest) in exchange for the current price today is called a zero-interest bond or zero-coupon bond. In such situations, one would be interested to know what rate of interest the advertiser is offering. One can use the concept of present value to find out the rate of return or yield of these offers. The rate of return of an investment is called internal rate of return since it depends exclusively on the cash flows of the investment. 36
