Multiple Cash Flows In the previous chapter, we laid the groundwork for  discounted  cash flow valuation  with single cash flows. Now, we learn how to deal with multiple cash flows, which is  more realistic in making financial decisions. Usually a large cash outflow is followed by an stream of future  cash inflows.  From this point forward, we will assume compound  interest in all our work. 6
Timelines Visualizing what is happening is helpful in  setting up the problem. Draw at  timeline  for the following scenarios: Deposit \$1,000 per year into your savings account  for four years, starting now, to save for a house. Receive lottery winnings of \$10,000 a year for five  years starting one year from now. Invest \$1,000 toward retirement today and invest  7

Multiple Cash Flows - FV Let’s solve the first one…you deposit \$1,000 per  year into your savings account for four years,  starting now, to save for a house.  How much  money will you have at the end of four years? What are we missing?? 12
Multiple Cash Flows - FV 13 r  = .08 0 1 2 3 4 \$1,000 \$1,000 \$1,000 \$1,000 Why can’t we just add the four amounts and  grow them at 8% like we did before? We already know that we can calculate  equivalent values for single cash flows in the  future. ??

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

Kiran Temple University Fox School of Business ‘17, Course Hero Intern

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

Dana University of Pennsylvania ‘17, Course Hero Intern

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
