time value of money
money can be invested today to earn interest and grow to a larger dollar amt in the future
has nothing to do with the worth or buying power of the dollars
ex:
invested in bank $100
annual yield is 6%
FV is $106
time value of money is useful for
valuing a variety of assets/liabilities and rev/exp
interest
amount of money paid/received in excess of the amt of money borrowed or lent
simple interest
initial investment x annual interest rate x period of time
can also do: [ I x R x T ]/100
compound interest
includes interest not only on the initial investment, but also on the accumulated interest in previous periods
when money remains invested for multiple periods
how else can you calculate compound interest
future value of a single amount
effective rate
actual rate at which money grows per year
interest rate per compounding period for effective rate (what must be done to %)
semiannually –>
12% / 2 = 6%
quarterly –>
12% / 4 = 3%
monthly –>
12% / 12 = 1%
future value (of a single amount)
is the amt of money that a dollar will grow to at some point in the future
also principle + interest
formula for future value (of a single amount)
FV = I (1+i)^n
FV = FV of invested amt
I = amt invested at the beginning period
i = interest rate per compounding period
n = number of compounding periods
what must change to the FV formula when interest is compounded semiannually
if its 1,000 @ 10%, for three years
semi annual is 2 times a year
must multiply n x 2
divide r / 2
so:
1000 [1+ (.01/2)] ^ 3 x 2
NOTE: if using table, your table amount would be multiplied by 1,000
BUT what is the formula for future value of a single amt when using the table
FV = I x FV Factor
example: assume invested $1,000 in an investment account for three years paying 10% interest compounded annually
FV = $1,000 x FV Factor
FV = $1,000 x 1.331
FV = $1,331
present value (of a single amount)
PV = [FV]/[(1 + i)^n]
example: present value of $1,331 received at the end of three years when the interest rate is 10%
PV = FV x PV Factor
PV = $1,331 x .75131
PV = $1,000
What is a result of PV
requires the removal of compound interest
higher the interest rate –> lower the present value
further into the future –> lower the present value
determining an unknown interest rate
PV = 500
FV = 605
n = 2
FV/PV = 605/500 = 1.21 (in table)
look under n=2
so i = 10%
Determining an unknown number of periods
PV = 10,000
FV = 16,000
i = 10%
n =?
10,000/16,000 = .625
under 10% –> .625 –> n = 5
valuing a note: one payment, explicit interest
company sold shoes to Sporting Goods Inc. for $50,000.
Shoe Company agrees to accept a note in payment for the shoes requiring payment for $50,000 in one year plus interest at 10%
FV is 55,000
because 50,000 –> then 10% of 50,000
what is PV today?
55,000 x .90909 = 50,000
.90909 comes from table (n=1, i = 10)
valuing a note: one payment, no interest stated
Shoe Co sells shoes to Sporting Goods Inc.
Terms of sale require Sporting Goods Inc to sign a non-interest bearing note of 60,500 with payment due in 2yrs
know that the FV is 60,500
n = 2
i = 10%
what is PV?
to find PV (price of shoes) have to know either the cash price of the shoes? or the interest rate? (we were given interest rate)
60,500 (fv) x .82645 = 50,000 (pv)
.82645 comes from table ( n= 2, i = 10%)
annuity
series of cash flows of the same amount received or paid each period
examples of when need annuities
loan where periodic interest is paid in equal amounts
a lease paid in equal installments during a specified period
ordinary annuity
cash payments occur at the END of each period
if have to make payments “due at the end of each year” –>
today (NO)
1: end of year one
2: end of year two
3: end of year three
annuity due
cash payments occur at the beginning of each period
so if have to make three payments “immediately” –> 1: today,
2: end of year 1,
3: end of year two
future value of ordinary annuity
“accumulate” ,
rather than investing single amount today,
investing 10,000 over the next three years,
10% interest compounded annually,
first payment is made one year from today,
how much will accumulate in the acct by the end of year 3?
SOLVE:
- formula
- PMT x table value
Future value of annuity due
not investing single amount today,
growing to future value, decide to invest 10,000 a year over the next three years, 10% interest compounded annually,
making the first payment immediately
how much will you have in acct at end of three years?
SOLVE:
- formula
- PMT x table
