2. WHY THIS TOPIC MATTERS
TO YOU
IN PROFESSIONAL LIFE:
ACCOUNTING:
You need to understand time-value-of-money
calculations to account for certain transactions
such as loan amortization, lease payments, and
bond interest rates.
3. INFORMATION SYSTEM:
You need to understand time-value-of-money
calculations to design systems that accurately
measure and value the firm’s cash flows.
MANAGEMENT:
You need to understand time-value-of-money
calculations so that you can manage cash
receipts and disbursements in a way that will
enable the firm to receive the greatest value
from its cash flows.
4. MARKETING
You need to understand time value of money
because funding for new programs and products
must be justified financially using time-value-ofmoney techniques.
OPERATIONS
You need to understand time value of money
because the value of investments in new
equipment, in new processes, and in inventory will
be affected by the time value of money.
5. IN YOUR PERSONAL LIFE
Time value techniques are widely used in
personal financial planning. You can use them
to calculate the value of savings at given future
dates and to estimate the amount you need
now to accumulate a given amount at a future
date.
You also can apply them to value lump-sum
amounts or streams of periodic cash flows and
to the interest rate or amount of time needed to
achieve a given financial goal.
6. Learning Objectives
• Discuss the role of time value in finance and the use
of computational aids used to simplify its application.
• Understand the concept of future value, its calculation
for a single amount, and the effects of compounding
interest more frequently than annually.
• Find the future value of an ordinary annuity and an
annuity due and compare these two types of annuities.
• Understand the concept of present value, its
calculation for a single amount, and its relationship to
future value.
7. Learning Objectives
• Calculate the present value of a mixed stream of cash
flows, an annuity, a mixed stream with an embedded
annuity, and a perpetuity.
• Describe the procedures involved in:
– determining deposits to accumulate a future sum,
– loan amortization, and
– finding interest or growth rates
8. The Role of Time Value in Finance
• Most financial decisions involve costs & benefits that
are spread out over time.
• Time value of money allows comparison of cash flows
from different periods.
Question?
Would it be better for a company to invest
$100,000 in a product that would return a total of
$200,000 in one year, or one that would return
$500,000 after two years?
9. The Role of Time Value in Finance
• Most financial decisions involve costs & benefits that
are spread out over time.
• Time value of money allows comparison of cash flows
from different periods.
Answer!
It depends on the interest rate!
10. Present Value and Future Value
PRESENT VALUE
FUTURE VALUE
•
Is the cash on hand today
•
•
It is the amount you need
today in to reach a future value
•
•
PRESENT VALUE
TECHNIQUE uses
discounting to find its present
valueof each cash flow at time
zero and then sums these
values to find the investment’s
value today
•
Is cash you will receive at a
given future date
It is the amount you will
receive in the future from your
cash on hand
FUTURE VALUE TECHNIQUE
uses compounding to find
future value of each cash flow
at the end of the investment’s
life and then sums these
values to find the investment’s
future value

19. BASIC PATTERNS OF CASH FLOW
• SINGLE AMOUNT: a lump sum amount
either currently held or expected at some
future date
• ANNUITY: a level periodic stream of cash
flow
• MIXED STREAM: a stream of unequal cash
flows that reflect no particular pattern
20. Future Value Example
Algebraically and Using FVIF Tables
You deposit $2,000 today at 6%
interest. How much will you have in 5
years?
$2,000 x (1.06)5 = $2,000 x FVIF6%,5
$2,000 x 1.3382 = $2,676.40

22. Compounding More Frequently
than Annually
• Compounding more frequently than once a year
results in a higher effective interest rate because you
are earning on interest on interest more frequently.
• As a result, the effective interest rate is greater than
the nominal (annual) interest rate.
• Furthermore, the effective rate of interest will increase
the more frequently interest is compounded.
23. Compounding More Frequently
than Annually
• For example, what would be the difference in future
value if I deposit $100 for 5 years and earn 12%
annual interest compounded (a) annually, (b)
semiannually, (c) quarterly, an (d) monthly?
Annually:
100 x (1 + .12)5 =
$176.23
Semiannually:
100 x (1 + .06)10 =
$179.09
Quarterly:
100 x (1 + .03)20 =
$180.61
Monthly:
100 x (1 + .01)60 =

25. Continuous Compounding
• With continuous compounding the number of
compounding periods per year approaches infinity.
• Through the use of calculus, the equation thus
becomes:
FVn (continuous compounding) = PV x (ekxn)
where “e” has a value of 2.7183.
• Continuing with the previous example, find the Future
value of the $100 deposit after 5 years if interest is
compounded continuously.
26. Continuous Compounding

compounding periods per year approaches infinity.
• Through the use of calculus, the equation thus
becomes:
FVn (continuous compounding) = PV x (ekxn)
where “e” has a value of 2.7183.
FVn = 100 x (2.7183).12x5 = $182.22
27. Present Value Example
Algebraically and Using PVIF Tables
How much must you deposit today in order to
have $2,000 in 5 years if you can earn 6%
interest on your deposit?
$2,000 x [1/(1.06)5] = $2,000 x PVIF6%,5
$2,000 x 0.74758 = $1,494.52

29. Annuities
• Annuities are equally-spaced cash flows of equal size.
• Annuities can be either inflows or outflows.
• An ordinary (deferred) annuity has cash flows that
occur at the end of each period.
• An annuity due has cash flows that occur at the
beginning of each period.
• An annuity due will always be greater than an
otherwise equivalent ordinary annuity because interest
will compound for an additional period.
31. Future Value of an Ordinary Annuity
Using the FVIFA Tables
• Annuity = Equal Annual Series of Cash Flows
• Example: How much will your deposits grow to if you
deposit $100 at the end of each year at 5% interest for
three years.
FVA = 100(FVIFA,5%,3) = $315.25
Year 1 $100 deposited at end of year
=
$100.00
Year 2 $100 x .05 = $5.00 + $100 + $100
=
$205.00
Year 3 $205 x .05 = $10.25 + $205 + $100 =
$315.25

• A perpetuity is a special kind of annuity.
• With a perpetuity, the periodic annuity or cash flow
stream continues forever.
PV = Annuity/k
• For example, how much would I have to deposit today
in order to withdraw $1,000 each year forever if I can
earn 8% on my deposit?

44. Compounding Interest More
Frequently Than Annually
• Interest is often compounded more frequently than
once a year. Savings institutions compound interest
semi-annually, quarterly, monthly, weekly, daily, or
even continuously.
SEMIANNUAL COMPOUNDING of interest involves
two compounding periods within the year. Instead of
the stated interest rate being paid once a year, onehalf of the stated interest rate is paid twice a year.
QUARTERLY COMPOUNDING of interest involves four
compounding periods within the year. One-fourth of
the stated interest rate is paid four times a year.

• The nominal interest rate is the stated or contractual
rate of interest charged by a lender or promised by a
borrower.
• The effective interest rate is the rate actually paid or
earned.
• In general, the effective rate > nominal rate whenever
compounding occurs more than once per year
EAR = (1 + i/m) m -1
56. Nominal & Effective Rates
• For example, what is the effective rate of interest on
your credit card if the nominal rate is 18% per year,
compounded monthly?
EAR = (1 + .18/12) 12 -1
EAR = 19.56%
57. Special Applications of Time Value
Future value and present value techniques
have a number of important applications in
finance. We’ll study four of them in this
section:
1.Determining deposits needed to accumulate
a future sum.
2.Loan amortization
3.Finding interest or growth rates, and
4.Finding an unknown number of periods
58. Determining Deposits Needed to
Accumulate a Future Sum
Supposed you want to buy a house 5 years from now,
and you estimate that an initial down payment of
P30,000 will be required at that time. To accumulate
the P30,000, you will wish to make equal annual end-ofyear deposits into an account paying annual interest of
6 percent.

61. Loan Amortization
The term loan amortization refers to the
determination of equal periodic loan
payments.
Lenders use a loan amortization schedule to
determine these payment amounts and the
allocation of each payment to interest and
principal.
Amortizing a loan actually involves creating
an annuity out of a present amount.
62. Loan Amortization
You borrow P6000 at 10 percent and agree to
make equal annual end of year payments over
4 years.

• At times, it may be desirable to determine the
compound interest rate or growth rate implied by a
series of cash flows.
• For example, you invested $1,000 in a mutual fund in
1994 which grew as shown in the table below?

It is first important to note
that although there are 7
years show, there are only 6
time periods between the
initial deposit and the final
value.
69. Determining Interest or Growth Rates
• At times, it may be desirable to determine the
compound interest rate or growth rate implied by a
series of cash flows.
• For example, you invested $1,000 in a mutual fund in
1994 which grew as shown in the table below?

71. Finding an unknown Number of
Periods
• Ann Bates wishes to determine the number of years it
will take for her initial P1000 deposit, earning 8% annual
interest, to grow to equal P2,500. Simply stated, at an
8% annual rate of interest, how many years, n will it take
for Ann’s P1000,PV, to grow to P2,500,FV?
• Table Use:
• We begin by dividing the amount deposited in the
earliest year by the amount received in the latest year.
This will result to present value interest factor
• Use Table A-2
