Time ValueA. Process of expressing
1. The present value of $1 invested now in future terms. (Compounding)
Compounding – Process by which interest is paid on interest that was previously earned.
2. The future value of $1 invested in terms of the present
Future Value of a dollar – Amount to which a single payment will grow at some rate of interest.
B. Payments are either: 1. a single payment 2. A series of equal payments (an annuity)
3
Time Value
C. Time value of money problems may be solved by using:1. Interest tables2. Financial calculators3. Software
4
Variables for Time Value of Money Problems
PV = present valueFV = future valuePMT = annual paymentN = number of time periodsI = interest rate per period
5
Future Value
Future value of $1 takes a single payment in the present into the future.
General equation for the future value of $1:
P0(1 + i)n = Pn
FV = PV (1 + i)n
7
Greater Terminal Values
Higher interest rates
Longer time periods
Result in greater terminal values
9
Present Value
Present value of $1 brings a single payment in the future back to the present.Present Value – Current value of a dollar to be
received in the future.Discounting – Process of determining present
value.
10
Present Value
General equation for the present value of $1:P0 = Pn
(1+i)n
PV = FV [ 1 / (1 + i)n ]
1. PV = Present Value
2. FV = Future Value
3. i = Interest Rate per Period
4. n = Number of Compounding Periods
14
Financial Calculators and Excel
Express the cash inputs (PV, FV, and PMT) as cash inflows and cash outflows
At least one of the cash variables must be –an inflow (+)–an outflow (-)
15
Simple Interest
Simple Interest – No Compounding– Good to have if you withdraw interest each
period.
– SI = Principal (PV) x rate (i) x time (n)
16
Future Value of a Single Amount Example
You buy a stock for $10 and expect the price to increase 9 percent annually. After 10 years, what is the anticipated price of the stock?
17
Future Value of a Single Amount Example
The unknown: FVThe givens:
–PV = 10
–PMT = 0
–N = 10
–I = 9
The answer: $23.67
18
FV Interpretation
A $10 stock will be worth $23.67 after 10 years if its price grows 9% annually.
19
Present Value of a Single Amount Example
What is the cost of a stock that was sold for $23.67, held for 10 years and whose value appreciated 9 percent annually?
20
Present Value of a Single Amount Example
The unknown: PVThe givens:
–FV = 23.67
–PMT = 0
–N = 10
–I = 9
The answer:$10
21
Interpretation
$23.67 received after ten years is worth $10 today if the rate of return is 9 percent.
22
Interpretation of Future and Present Values
These two problems are mirror images: In the first case, the $10 is compounded
into its future value ($23.67).In the second case, the future value
($23.67) is discounted back to its present value ($10).
23
Rate of Return Example
A stock was purchased for $10 and sold for $23.67 after 10 years. What was the return?
24
Future Determination of the Interest Rate(can use Present too)
The unknown: IThe givens:
–PV = 10
–PMT = 0
–N = 0
–FV = 23.67
The answer: 9%
26
Non-annual Compounding
More than one interest payment a year
State Interest rates are always annual interest rates.
More frequent compounding
27
Non-annual Compounding
Multiply number of years by frequency of compounding
Divide interest rate by frequency of compounding
28
Periods less than One Year
Same variables as in all time value problems except N < 1.
Calculate by dividing the number of days by 365.
29
Illustration for Return on Investment
What is the return on an investment that costs $98,543 and pays $100,000 after 45 days?
30
Determination of Return
The unknown: IThe givens:
–PV = -98,543
–N = 0.1233 (45/365)
–FV = 100,000
–PMT = 0
The answer: 12.64%
