After studying Chapter 3, After studying Chapter 3, 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.

The future value of an ordinary annuity can be viewed as
occurring at the endend of the last cash flow period, whereas the future value of an annuity due can be viewed as occurring at the beginningbeginning of the last cash

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.

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)
RR = $10,000$10,000 / 3.605 = $2,774$2,774
