Discounted Cash Flow Analysis
(Time Value of Money)
? Discounted Cash Flow (DCF) analysis is the foundation of
valuation in corporate finance
? To use DCF we need to know three things
? The size of the expected cash flows
? The timing of the cash flows
? The proper discount (interest) rate
? DCF allows us to compare the values of alternative cash
flow streams in dollars today (Present Value)

FUTURE VALUE
(COMPOUNDING):
What will $100 grow to after 1 year at 10% ?

|----------------------|
-100
interest

end of period value 110
FV1 = PV0 (1+r) = 100 (1.1) = 110
where FV1 is the future value in period 1
PV0 is the present value in period 0 (today)
NOTE: When r=10%, $100 received now (t=0) is
equivalent to $110 received in one year (t=1).
What will $100 grow to after 2 years at 10% ?

FV2 = PV0 (1+r) (1+r)= PV0 (1+r)2
= 100 (1.1)2 = 100 (1.21) = 121
NOTE: $100 received now (t=0) is equivalent to
$110 received in one year (t=1) which is also
equivalent to $121 in 2 years (t=2).

The general formula for future value in year N (FVN)
FVN = PV0 (1+r)N
What will $100 grow to after 8 years at 6% ?
What is the present value of $159.40 received
in 8 years at 6%?
Or
How much would you have to invest today at 6%
in order to have $159.40 in 8 years?

PRESENT VALUE IS THE RECIPROCAL
OF FUTURE VALUE:
PV0 = FVN /(1+r)N
Note: Brealey & Myers refer to 1/(1+r)N as a
¡°discount factor¡±.
The discount factor for 8 years at 6% is
1/(1+.06)8 = 0.627
Thus, the present value of $1.00 in 8 years
at 6% is $0.627.
What¡¯s the present value of $50 in 8 years?

PRESENT VALUE PROBLEMS
Which would you prefer at r=10%?
$1000 today vs. $2000 in 10 years
There are 4 variables in the analysis
PV, FV, N, and r
Given three, you can always solve
for the other
