Future Values
Future Value - Amount to which an
investment will grow after earning interest.

Compound Interest - Interest earned on
interest.

Simple Interest - Interest earned only on the
original investment.
Future Values
Example - Simple Interest
Interest earned at a rate of 6% for five years on
a principal balance of \$100.

Interest Earned Per Year = 100 x .06 = \$ 6
Future Values
Example - Simple Interest
Interest earned at a rate of 6% for three years
on a principal balance of \$100.

Value           100      106       112 118

Value at the end of Year 3 = \$118
Future Values
Example - Compound Interest
Interest earned at a rate of 6% for three years on
the previous year’s balance.

Interest Earned Per Year =Prior Year Balance x
.06
Future Values
Example - Compound Interest

Number of Years
Example: Mutual Fund Fees and
Retirement Savings
Prof. Finance moves to a new university and has
\$100,000 in retirement savings to invest (rollover)
into a new retirement account.
Prof. Finance wants to invest this money for 25
years into an indexed stock fund, which is
expected to return 9% annually.
Prof. has two choices: Vanguard Total Equity
Fund with a 0.4% annual expense fee and
Onguard Total Fencing Fund with an 1.2% annual
expense fee.
What is the difference in Prof. Finance’s expected
future retirement savings between the two funds?
Present Values
Present Value                     Discount Factor
Value today of a                   Present value of
future cash                        a \$1 future
flow.                            payment.

Discount Rate
Interest rate used
to compute
present values of
future cash flows.
Present Values

Present Value = PV

Future Value after t periods
PV =              (1+r) t
Example: Paying for Baby’s
MBA
Just had a baby. You think the baby will
take after you and earn academic
scholarships to attend college to earn a
Bachelor’s degree. However, you want
send your baby to a top-notch 2-year MBA
program when baby is 25. You have
estimated the future cost of the MBA at
\$85,000 for year 1 and \$89,000 for year 2.
Example: Paying for Baby’s
MBA
Today, you want to finance both years of
baby’s MBA program with one payment
(deposit) into an account paying 8%
interest compounded annually.
How large must this deposit be?

Annuities
Annuity: a sequence of equal cash flows,
occurring at the end of each period. This
is known as an ordinary annuity.

Examples of Ordinary Annuities:
semi-annual coupon interest payments
over the life of the bond.
If you borrow money to buy a house or a
car, you will pay a stream of equal
payments.

occurring at the beginning of each period.

Example: Invest Early in an IRA
How much would you have at age 65 if
you deposit \$2,500 at the end of each
year in an account paying 9% annually
starting at:
   (A) age 41?
   (B) age 22?
Why an IRA?
Imagine in the last example, you didn’t take
advantage of the tax-sheltered environment of
an IRA.
Your annual investment return would be taxed!
With a 28% tax rate, our annual after-tax return
would fall from 9% to 6.48% (=9%(1-.28)).
At age 65: I would have \$135,519 vs. \$191,975.
You would have \$535,392 vs. \$1,102,114: 52%
less!! The IRS killed Kenny,…!
Example: Enjoying your
Retirement
You go ahead and make the contributions
starting at age 22 in the last example, giving you
\$1,102,114 at age 65.
You expect to live to age 85. So, you want to
make 20 annual withdrawals from your IRA
paying 9% at the beginning of each year starting
at age 65.
How large can this annual withdrawal be?
More annuity fun, enjoying your
release from baseball
Bob B. is released from the last year of his
guaranteed contract from a New York
baseball team. He is due \$5.9 million from
the last year of this contract. Bob and the
team agree to defer the \$5.9 million at 8%
interest for 15 years. At this time (15 years
from today), the team will begin the first of 15
equal annual payments at 8% interest.
The press is reporting the payments will total
\$30 million. Are they correct?
Non-Annual Interest
Compounding
When interest is compounded more frequently than once
a year.
Important non-annual compounding terms and things to
know:
   Quoted Annual Rate, or Annual Percentage Rate (APR):
Stated nominal annual rate before compounding.
   Effective Annual Rate (EAR): the actual (effective) annual
interest rate earned or paid.
   Periodic Interest Rate: the interest rate paid or charged
each interest compounding period = quoted rate/m, where
m = number of compounding periods per year.
Effective Interest Rates
example
Given a monthly rate of 1%, what is the Effective
Annual Rate(EAR)? What is the Annual
Percentage Rate (APR)?
12
EAR = (1 + .01) - 1 = r
12
EAR = (1 + .01) - 1 = .1268 or 12.68%

APR = .01 x 12 = .12 or 12.00%
FV and PV with non-annual
interest compounding
n = number of years
m = number of times interest is paid per
year
APR = nominal annual rate (APR)
APR/m = periodic rate
Single CF
FVnm = PV(1+ARR/m)nm
PV = FVnm/(1+APR/m)nm
Non-annual annuities
Ordinary:
PV = C(PVAFAPR/m,nm)
FVnm = C(PVAFAPR/m,nm)(1+APR/m)nm

Annuity-Due:
PV = C(PVAFAPR/m,nm)(1+APR/m)
FVnm = C(PVAFAPR/m,nm)(1+APR/m)nm+1
Example: Low Rate or Rebate?

The Frontier family want to buy a sport ut (SUV). They decide
on a 4-wheel drive Jeep Grand Cherokee. The purchase price
with tax of the vehicle is \$32,500. The Frontiers have \$4,000
as a down payment.
Jeep offers the choice of two incentives on the 4-door Grand
Cherokee.
   0% APR Financing for 60 months, or
   \$3,000 rebate which would be applied toward the purchase price.
If the Frontiers elect to take the rebate, they can get 4.49% APR
financing for 60 months.
   Question: Which incentive would give the Frontiers the lowest
monthly payment?
Example: The \$200 national ISP
signup credit: good deal for whom?
A national ISP all provide \$200 for new customers to use
at a particular electronics store chain if they sign-up for a
2-year internet service contract at \$21.95/month.
What interest rate (APR) are you paying on this “free
money” if you wanted internet service and could get it for
free? (200 PV, -21.95 PMT, 24 N 0 FV, CPT I/Y =
9.8%/month x 12= 117.8% APR!!)
What interest rate (APR) are you paying on this “free
money” if you wanted internet service and could get it for
\$9.95/month?(-12 PMT CPT I/Y = 3.15%/mo x 12 =
37.8%! Thanks, but no thanks!
Inflation
Inflation - Rate at which prices as a whole
are increasing.

Nominal Interest Rate - Rate at which
money invested grows.

Real Interest Rate - Rate at which the
increases.
Inflation
1+ nominal interest rate
1  real interest rate =     1+inflation rate

approximation formula

Real int. rate  nominal int. rate - inflation rate
Inflation
Example
If the interest rate on one year govt. bonds is
5.0% and the inflation rate is 2.2%, what is the
real interest rate?
1+.050
1  real int erestrat e = 1+.022       Savings

1  real int erestrat e = 1.027          Bond

real int erestrat e = .027 or 2.7%

ion
Approximat = .050 - .022 = .028or 2.8%
Example: Real retirement income
Going back to your retirement in 43 years,
you expect 3% inflation along with your
9% nominal investment rate annually and
want to withdraw \$32,000 in real terms at
the beginning of each year for 20 years
once you retire.
How will this change your retirement
saving plans?
