1
Time Value of Money Many financial decisions require comparisons of cash payments at different dates Example: 2 investments that require an initial investment of $100 Timing Inv 1 Inv 2 After 1 year $30 $20 After 2 years $30 $20 After 3 years $30 $40 After 4 years $30 $60 If you should choose one of them, which would you choose?

2
Compounding Future Value: amount to which an investment will grow after earning interest Compounding: the process of accumulating interest in an investment over time to earn more interest Compound interest: Interest earned on both the initial principal and the reinvested interest from prior periods

3
**Time principal Interest 0 $100 $0 1 $100 $10 2 $110 $11 **

Future Value FV of $100 in 2 years if k=10% Time principal Interest 0 $100 $0 1 $100 $10 2 $110 $11 So $100 today $121 in 2 years

4
**simple and compounded interest?**

What is the difference between simple and compounded interest? Compound interest assumes accumulated interest is reinvested (therefore, interest earns interest). Simple interest assumes interest is not reinvested. Interest is earned each period on the original principal only.

5
**Present Value and Discounting**

Present Value: value today of a future cash flow PV is simply the reverse of future value PV works backward through time, while future value goes forward through time Discounting: finding present value of some future amount

6
**Example 3 different ways to find future value of a single cash flow**

Find FV of $100 in 2 10% FV2= 100*(1+10%) formula = 100 FVIF2,10% table PV i n FV financial calculator in general FVn= PV (1+i)n PV, FV formulas are based on this equation 4 variables given any 3, you can calculate the 4th

7
**solving for n in how many years will $100 grow to $121 @ i= 10%**

Formula way: 100*(1+10%)n =121 (1+10%)n =1.21 n ln(1+10%)=ln 1.21 Table way: 100 FVIFn,10% =121 FVIFn,10% =1.21 Refer to FVIF Table. Look down the 10% column to find 1.21. Financial calculator way: PV i FV n

8
Solving for i At what rate of return will $100 grow to $121 in 2 years Formula way: 100*(1+i)2 =121 (1+i)2 = 1.21 1+i = (1.21)1/2 =1.10 i = 0.10 = 10% Table way: 100 FVIF2,i =121 FVIF2.i =1.21 Refer to FVIF Table. Look across 2 period row to find 1.21. Financial calculator way: PV n FV i

9
**Present and future value of multiple cash flows**

Calculate PV(FV) of each cash flow and add them up: e.g. i=10% PV = 100/(1+10%)+ 300/(1+10%) /(1+10%) formula way PV = 100 PVIF1,10% PVIF2,10% PVIF3,10% table way 10 i CFi CFi CFi CFi NPV financial calculator

**Valuing Level Cash Flows: Annuities and Perpetuities**

We often deal with situations where cash flows are same throughout the problem. For example, a car loan, rent payment etc. An annuity is a level stream of cash flows for a fixed period of time. Cash flow must be the same in each period. Ordinary annuity: Payments are at the end of period Annuity due: Payments are at the beginning of period Unless stated otherwise, assume you deal with ordinary annuity

11
**Future value of an annuity**

FVA3 = A (1+i)2 + A (1+i) + A formula way = A {(1+i)2 + (1+i) + 1} = A FVIFA3,i% table way A PMT r i n FV financial calculator way again given any 3, we can solve for the 4th

12
**Present value of an annuity**

PVA3 = A/(1+i)3 + A/(1+i)2 + A/(1+i) formula way = A {1/(1+i)3 + 1/(1+i)2 + 1/(1+i)} = A PVIFA3,i% table way A PMT r i n PV financial calculator way

13
**deriving the PVIFA3,i% formula**

use sum of infinite geometric series formula: asa one can show that

14
**deriving the PVIFA3,i% formula**

15
Perpetuities A special case of an annuity is when the cash flows continue forever. The most common application of perpetuities in finance is preferred stock Preferred stock offers a fixed cash dividend every period (usually every quarter) forever. The dividend never increases in value, so it’s similar to a bond with a fixed interest payment. Present value of a perpetuity

16
**Comparing Interest Rates**

How do you compare interest rates? Rates can be quoted monthly, annually or something in between, and it quickly becomes confusing to try and determine the “real” interest rate. Stated Rate ( also called APR, Quoted Rate, Nominal Rate): rate before considering any compounding effects e.g. 10% APR quarterly compounding Periodic Rate: APR/(# of times compounding occurs in a year) It is the effective or “real” rate. It considers the compounding effects.

17
Effective Annual Rate Effective Annual Rate (EAR) Rate on an annual basis that reflects all compounding effects EAR= (1+APR/n)n – 1 You can compare different interest rate quotations by using EAR

18
**Timing of cash flows tells you what the period is **

Note: in TVM problems Timing of cash flows tells you what the period is Find and use the periodic rate that is consistent with the period definition

19
**Loan Amortization: There are many different kinds of loans available**

Pure discount loan With such a loan, the borrower receives money today and repays a single lump sum at some time in the future. Interest-only loans This kind of loan repayment plan calls for the borrower to pay interest each period and repay the entire principal at some point in the future.

20
**different types of loans**

Amortized loans With a pure discount or interest-only loan, the principal is paid all in once. An alternative is an amortized loan where the lender may require the borrower to repay parts of the loan amount over time. The process of paying off a loan by making regular principal reductions is called amortizing the loan. Partially amortizing loan Similar to amortized loan except the borrower makes a single, much larger final payment called a “balloon” to pay off the loan.

21
Example You get a $10,000 car loan. It is a five year amortized loan with annual installments. 12% is the interest rate charged by the bank. Develop the amortization schedule.
