After studying this part,After studying this part,
you should be able to:you should be able to:
1. Understand what is meant by "the time value of money."
2. Understand the relationship between present and future value.
3. Describe how the interest rate can be used to adjust the value of
cash flows – both forward and backward – to a single point in
time.
4. Calculate both the future and present value of: (a) an amount
invested today; (b) a stream of equal cash flows (an annuity);
and (c) a stream of mixed cash flows.
5. Distinguish between an “ordinary annuity” and an “annuity due.”
6. Use interest factor tables and understand how they provide a
shortcut to calculating present and future values.
7. Use interest factor tables to find an unknown interest rate or
growth rate when the number of time periods and future and
present values are known.
8. Build an “amortization schedule” for an installment-style loan.

Hint on Annuity ValuationHint on Annuity Valuation
The present value of an ordinary
annuity can be viewed as
occurring at the beginningbeginning of the
first cash flow period, whereas
the future value of an annuity
due can be viewed as occurring
at the endend of the first cash flow
period.

Defining the calculator variables:
For CF0: This is ALWAYS the cash flow occurring
at time t=0 (usually 0 for these problems)
For Cnn:* This is the cash flow SIZE of the nth
group of cash flows. Note that a “group” may only
contain a single cash flow (e.g., $351.76).
For Fnn:* This is the cash flow FREQUENCY of the
nth group of cash flows. Note that this is always a
positive whole number (e.g., 1, 2, 20, etc.).

Julie Miller is borrowing $10,000$10,000 at a
compound annual interest rate of 12%.
Amortize the loan if annual payments are
made for 5 years.
Step 1: Payment
PVPV00 = R (PVIFA i%,n)
$10,000$10,000 = R (PVIFA 12%,5)
$10,000$10,000 = R (3.605)
