Time lines & Future Value
CompoundingThe arithmetic process of determining the final value of a cash flow or series of cash flows when compound interest is applied.
Future value (FV)the amount cash flow(s) will grow over a given period of time when compounded at a given interest rate.
Time lines & Future Value
PV=present value (beginning amount).PV = $100
i = interest rate for one yeari = 5%, or i = 0.05
INT = dollars of interest earned during the yearINT = $100(0.5) = $5
FVn = the value n years into the futuren = number of periods in the analysis, n = 1
FVn = FV1 = PV + $105

FVN = PV(1 + i)n
The equation has 4 variables. If we know any 3 we can solve for the 4th.
Problem format:

-100 FV=?
FVN = PV(1 + i)n = $100(1.05)5
Present Value
Opportunity cost rate The rate of return on the best available alternative
investment of equal risk, or the rate of return you could earn on an alternative
investment of similar risk. Present Value (PV)
The value today of a future cash flow or series of cash flows The $100 is defined as the present value (PV) of
$126.63 due in 5 years when the opportunity cost rate is 5%.
If an alternative security is less than $100, buy it If an alternative security is more than $100, ignore it
Present Value
Fair (Equilibrium) ValueThe price at which investors are indifferent between buying or selling a security
DiscountingThe process of finding the present value of a cash flow or a series of cash flows; discounting is the reverse of compounding
Present Value
The present value of a cash flow due in n years is the amount, if in hand today, would grow to equal the future amount

PV = ? 127.63
Present Value
Discounting equation Start with the future value equation and solve for PV:
FVN = PV(1 + i)n
PV = FVN / (1 + i)n

Annuities
AnnuityA series of payments of an equal amount (PMT) at fixed intervals for a specified number of periods
Ordinary (deferred) annuityPMT occur at the end of each period
Annuity duePMT occur at the beginning of each period
Perpetuitiesa stream of equal payments expected to continue forever
Interest rates
Nominal (Quoted, Stated, APR) interest rateThe contracted, or quoted, or stated interest rate
Effective (Equivalent) annual rate (EFF% or EAR)The actual rate of interest actually being earned, as opposed to the quoted rate. Also called “equivalent annual rate.” Used to convert any nominal rate to an equivalent
annual rate These two rates may differ.
Amortized loans
Amortized* loansA loan that is repaid in equal payments over its life.
Amortized scheduleA table that shows how a loan will be repaid, showing how much is interest and how much is principal repayment
Example: $1,000 loan, 6% interest on loan balance$1,000 represents the PV of an annuity of PMT dollars per year for n years, discounted at 6%
Partial amortization with a balloon paymentpage 248
*mors = Latin for “kill”
