Q

What can interest rates be thought off - 3 ways (3)

A

First, they can be considered required rates of return—that is, the minimum rate of return an investor must receive in order to accept the investment.

Second, interest rates can be considered discount rates. In the example above, 5.26 percent is that rate at which we discounted the $10,000 future amount to find its value today. Thus, we use the terms “interest rate” and “discount rate” almost interchangeably.

Third, interest rates can be considered opportunity costs.

Q

Real risk-free interest rate - definition

A

The real risk-free interest rate
is the single-period interest rate for a completely risk-free security if no inflation were expected. In economic theory, the real risk-free rate reflects the time preferences of individuals for current versus future real consumption.

A

Q

Stated annual interest rate or Quoted interest rate - definition

A

Stated annual interest rate or Quoted interest rate
A quoted interest rate that does not account for compounding within the year. Also called stated annual interest rate. = rs.

20
Q

Effective annual rate (EAR) - defintion

A

Effective annual rate (EAR)
The amount by which a unit of currency will grow in a year with interest on interest included.

Q

Future value of a sum in N years with continuous compounding - Equation

22
Q

Effective annual rate (EAR) - definition

A

Effective annual rate (EAR)

25
Q

Periodic interest rate - definition

A

The periodic interest rate
is the stated annual interest rate divided by m, where m is the number of compounding periods in one year.

26
Q

Annual percentage rate (APR) - definition

A

Annual percentage rate (APR)
Measures the cost of borrowing expressed as a yearly rate.

27
Q

Present Value - Equation

A
28
Q

Non-annual compounding (Present Value) - Equation

A 
m = number of compounding periods per year 
rs = quoted annual interest rate 
N = number of years
29
Q

What happens to the PV when the discount rate is larger?

A

Holding time constant, the larger the discount rate, the smaller the present value of a future amount.

30
Q

What happens to the PV when the discount rate the farther in the future the amount to be received?

A

For a given discount rate, the farther in the future the amount to be received, the smaller that amount’s present value.

31
Q

An annuity - definition

A

An annuity
is a finite set of level sequential cash flows. Two types:
1) ordinary annuity
2) annuity due

Annuities may be handled in a similar approach as single payments if we use annuity factors rather than single-payment factors.

32
Q

An ordinary annuity - definition

A

An ordinary annuity
has a first cash flow that occurs one period from now (indexed at t = 1).

33
Q

An annuity due - definition

A

An annuity due
has a first cash flow that occurs/is paid immediately (indexed at t = 0).

34
Q

A perpetuity - definition

A

A perpetuity
is a perpetual annuity, or a set of level never-ending sequential cash flows, with the first cash flow occurring one period from now. A bond that does not mature.

35
Q

Present Value of a Series of Equal Cash Flows - Equation

A 
A = the annuity amount
r = the interest rate per period corresponding to the frequency of annuity

payments (for example, annual, quarterly, or monthly) N = the number of annuity payments

36
Q

General annuity formula (future value) - Equation

A

General annuity formula if we define the annuity amount as A, the number of time periods as N, and the interest rate per period as r.

37
Q

Ordinary annuity is called a perpetuity (a perpetual annuity) - Equation

A
38
Q

The present value of a perpetuity - Equation

A

where A is the periodic payment to be received forever.

39
Q

When present values, future values, and a series of cash flow are indexed at the same point in time what does this mean?

A

A lump sum can be seen as equivalent to an annuity, and an annuity can be seen as equivalent to its future value. Thus, present values, future values, and a series of cash flows can all be considered equivalent as long as they are indexed at the same point in time.

40
Q

The cash flow additivity principle - definition

A

The cash flow additivity principle
the idea that amounts of money indexed at the same point in time are additive—is one of the most important concepts in time value of money mathematics.

41
Q

Growth rate - Equation
