Organization of Chapter Financial math will be presented in the context of
personal finance. Later chapters will apply financial math to various finance applications for a hospitality firm.
Financial math topics covered include: Computation of future values, present values, annuity
payments, interest rates, etc. Perpetuities and non-constants cash flows Effective annual rates and compounding periods other
than annual

Future Value of a Lump Sum
The future value in 2 years of $1,000 earning 5% annually is an example of computing the future value of a lump sum. We can compute this in any one of three ways:
Using a calculator programmed for financial math
Solve the mathematical equation Using financial math tables (Table 5.1)

Solve for the Future Value
The general equation for future value is:
FVn = PV x (1+i)n
Computing the future value in the example:
FV2 = $1,000 x (1+5%)2 = $1,102.50

Present Value of a Lump Sum
How much do you need to invest today so you can make a single payment of $30,000 in 18 years if the interest rate is 8%? This is an example of the present value of a lump sum.
Again we can solve it using a programmed calculator, solving the math or using Table 5.2.

Annuities
Two or more periodic payments
All payments are equal in size.
Periods between each payment are equal in length.

PV Versus FV of an Annuity The value of an annuity can be expressed
as an equivalent lump sum value.
The PV of an annuity is the lump sum value of an annuity at a point in time earlier than the payments.
The FV of an annuity is the lump sum value of an annuity at a point in time later than the payments.

Ordinary Annuity Versus Annuity Due The PV of an ordinary annuity is located one period
before the first annuity payment.
The PV of an annuity due is located on the same date as the first annuity payment.
The FV of an ordinary annuity is located on the same date as the last annuity payment.
The FV of an annuity due is located one period after the last annuity payment.

Future Value of an Annuity Suppose you plan to deposit $1,000 annually
into an account at the end of each of the next 5 years. If the account pays 12% annually, what is the value of the account at the end of 5 years? This is a future value of an annuity example.
We can solve this problem using a programmed calculator, solving the math, or using Table 5.3.

Present Value of an Annuity You plan to withdraw $1,000 annually from an
account at the end of each of the next 5 years. If the account pays 12% annually, what must you deposit in the account today? This is an example of a present value of an annuity.
We can solve this problem using a programmed calculator, solving the math, or using Table 5.4.

Perpetuity—An Infinite Annuity
A perpetuity is essentially an infinite annuity. An example is an investment which costs you
$1,000 today and promises to return to you $100 at the end of each forever!
What is your rate of return or the interest rate?

The Present Value of a Perpetuity Another investment pays $90 at the end of
each year forever. If 10% is the relevant interest rate, what is the value of this investment to you today? We need to solve for the present value of the perpetuity.

Present Value of a Deferred Annuity
There are 3 different PV of annuity computations:
The payments on an ordinary annuity begin one period after the PV.
The payments on an annuity due begin on the same date as the PV.
The payments on a deferred annuity begin 2 or more periods after the PV. Thus it is called a deferred annuity since the payments are deferred more than one period from the present.

Computing the PV of a Deferred Annuity An investment promises to pay $100 annually
beginning at the end of 5 years and continuing until the end of 10 years. What is the value of this investment today at a 7% interest rate? Because the payments are deferred 5 years, this is a PV of deferred annuity problem.

PV of a Series of Non-Constant Cash Flows
The PV of a series of non-constant cash flows is just the sum of the individual PV equations for each cash flow.
Where the Cfi’s are a series of non-constant cash flows from year 1 to year n.

Compounding Periods Other Than Annual
Annuity computations require the annuity period and the compounding period to be the same.
For example, suppose a car loan for $12,000 required 48 equal monthly payments and uses a 9% annual rate compounded monthly. The annuity payments and the compounding periods are
both monthly. The interest rate needs to be expressed as a monthly rate:

Amortized Loans
Amortized loans are paid off in equal payments over a set period of time and can be viewed as the PV of an ordinary annuity.
An amortization schedule follows for a $120,000 mortgage to be paid of with 360 monthly payments of $965.55 each over 30 years. The interest rate is 9% annually compounded monthly or 0.75% per month.

Loan Amortization Schedule A loan amortization schedule shows:
The amount of each payment apportioned to pay interest. The amount paid towards interest declines since the principal balance is declining.
The amount of each payment apportioned to pay principal balance. The amount paid towards principal balance increases as the interest amount declines.
The remaining balance after each payment.
