Teaching Notes for Chapter 16
Before this chapter, many students have not studied the time value of money concept.
Although students have some intuitive sense of the concept (they want their money now
rather than later), they frequently have trouble with applications such as computing
interest, analyzing cash flows, and reading interest tables. This chapter introduces the
time value of money concept. It is more important to teach the basic concept than it is to
cover all of the details. To this end, we focus only on determining present values. We
leave discussion of future values to advanced courses. Likewise, we limit discussion to
ordinary annuities, leaving treatment of annuities due to future courses. Still, many
students will find this chapter challenging. We caution you to move your class at a pace
that promotes understanding rather than memorization.
Detailed Outline of a Lesson Plan for Chapter 16
I. Open the class using an entertaining example with which most students can
identify. Ask the class if they have been finalists in a Publisher’s Clearing
House $10,000,000 Sweepstakes. Point out that a winner (if there is one) does
not receive a check for $10,000,000. Instead, the winner would receive $500,000
per year for 20 years. Ask students to imagine that they win this annuity. Ask
them if they would be willing to accept $9,000,000 today rather than $500,000 per
year for the next 20 years. Most of them are likely to accept the $9 million
option. Now point out that the present value of one dollar to be collected in the
future is less than one dollar. In other words, students are willing to give up
$10,000,000 future dollars to get $9,000,000 present dollars. Next, ask students
how much less than $10,000,000 they would be willing to accept. Ask how many
students would take $8, $7, $6, $5, $4, $3, $2, or $1 million instead of the
$500,000 annuity. Students will likely choose different amounts. As students
notice the variety of drop out points their peers choose, they will be motivated to
learn a formal method for calculating the present value of an annuity.
II. Show students how to use the present value tables.
A. An interest rate or desired rate of return is used to convert future dollars to
their present values. Given a specified interest rate, you can use simple
algebra to make the conversion. For example, suppose a manager estimates
that a particular investment will yield a $33,000 cash inflow one year from
today. The business desires to earn a 10% rate of return. How much should
the manager be willing to pay for the investment today? In other words, what
is the present value of $33,000 to be received one year into the future? The
answer can be determined as follows:
Investment + (.10 x Investment) = Future Cash Inflow
