- Youve just been notified that you hold the
winning ticket in the Missouri lottery. The
jackpot is 1 million. You are given the option
of receiving 450,000 today, or 50,000 annually
at the end of each of the next 20 years. Assume
your opportunity rate is 10, and that taxes are
not an issue. Which option should you take?

- Bill and Sam are both 25 years old and plan to
retire at age 65. Suppose Bill begins investing
2,000 annually next year and does so through his
65th birthday. Sam doesnt begin investing until
his 46th birthday, but invests 10,000 annually
through age 65. Both earn 10 annually. Which one
has more money at retirement?

12TVM APPLICATIONRETIREMENT PLANNING
Waldo is 35 and wishes to retire in 30 years. He
would like to make 25 100,000 withdrawals from
his IRA, the first at age 66. Waldo also needs to
accumulate enough money to put his four-year-old
daughter, Laura, through college. He believes
she will require 25,000 at the beginning of each
of her four years in college. Assume Waldo can
earn a 9 after-tax return on his invested
capital, and plans to make 30 equal annual
deposits, the first to occur one year from today.
How large must each deposit be for Waldo to
accomplish his goals?
13SOLVING COMPLEX TIME VALUE PROBLEMS
- MARTINS METHOD
- Step 1 Draw a timeline, detail the cash
inflows and outflows - Step 2 Choose a focal point on the timeline
- Step 3 Equate the inflows and outflows at
the focal point solve for the unknown.

15TVM APPLICATION INTRAYEAR COMPOUNDING
You are looking at a home in Sunset Hills. The
selling price is 330,000 you plan to put
30,000 down. If you borrow the balance on a
30-year 8 1/8 fixed-rate mortgage, how much will
each monthly payment be? (Note the first payment
is due in one month.) How much interest will
you pay over the life of the loan? Suppose
that mortgage rates rise to 9 while you are
negotiating with the seller, and you didnt lock
in your rate. Now how much will each monthly
payment be? How much more interest will you pay
over the life of the loan?
