4-4 When we have UNEQUAL Payments over UNEQUAL number of periods We cant use Annuity… Uneven Cash flow Stream… Uneven Cash Flows

5
4-5 Present Value 10% Ali will receive the set of cash flows below. What is the Present Value at a discount rate of 10%? Uneven Cash Flows 5 0 1 2 3 4 5 Rs.600 Rs.600 Rs.400 Rs.400 Rs.100 Rs.600 Rs.600 Rs.400 Rs.400 Rs.100 PV 0 10%

4-9 General Formula: PV FV n = PV(1 + [i/m]) mn n: Number of Years m: Compounding Periods per Yeari: Annual Interest Rate FV n,m : FV at the end of Year n PV 0 : PV 0 : PV of the Cash Flow today Frequency of Compounding

10
4-10 Frequency of Compounding CompoundingInterest Year (i/m)No of Periods (nxm) Annually Semi-Annually Quarterly Monthly Daily

11
4-11 Rs.1,000 Ali has Rs.1,000 to invest for 2 years at an annual interest rate of 12%. Annual FV = Semi FV = Impact of Frequency

12
4-12 Qrtly FV Monthly FV= Daily FV= Impact of Frequency

13
4-13 Rs.1,000 Ali has to make equal payments of Rs.1,000 to for 3 years at an annual interest rate of 12% in order to have some amount in future. Annual FV = Semi FV = Impact of Frequency

14
4-14 For Present Value: Impact of Frequency

15
4-15 The actual rate of interest earned (paid) after adjusting the nominal rate for factors such as the number of compounding periods per year. Formula: Effective Annual Interest Rate

16
4-16 EAR Basket Wonders (BW) has a Rs.1,000 CD at the bank. The interest rate is 6% compounded quarterly for 1 year. What is the Effective Annual Interest Rate (EAR)? EAR EAR= ( 1 + 6% / 4 ) 4 - 1 = 1.0614 - 1 6.14%! =.0614 or 6.14%! BW’s Effective Annual Interest Rate

17
4-17 Suppose you borrow either through credit card which charges 12 % per month for a year or through bank loan with 12% interest rate that is compounded quarterly. What should you choose? Effective Annual Interest Rate

18
4-18 Loan Amortization If a loan is to be repaid in equal periodic payments, it is said to be amortized loan. It is an application of compounding interest and annuity. Example: Car Loan, Mortgage Loan, Student Loan

19
4-19 1.Calculate the payment per period. 2.Determine the interest in Period t. (interest x Beg. Amt) principal payment 3.Compute principal payment in Period t. (Payment - interest from Step 2) principal payment 4.Determine ending balance in Period t. (Balance - principal payment from Step 3) 5.Start again at Step 2 and repeat. Steps to Amortizing a Loan
