Time value • What is the difference between simple interest and compound interest? https://www.youtube.com/watch?feature=player_embedded&v=-qgdMTbTJlA
Let’s Look at the worksheet • In the worksheet, is there something special that needs to be done for a present value amount?
FV Example • If you were to invest $3,000 today, what would it be worth in 1 year if you can earn 10% on your investments on average? 2 Years? 5 years?
PV Example • When you were 10 years old your grandfather tells you that upon college graduation (age 22) he will give you $30,000. Inflation is expected to be 3.5%. What is this amount worth as a 10 year old?
PV example • When you retire at age 65, your retirement fund promises to pay you $150,000 the first year of your retirement. You are now 25. If inflation is 4%, what is this worth to you in today’s money? • If the company can earn 12% on its retirement investments, how much must they put away today to get the above payment?
Annuities • What are some examples of cash flows that are annuity cash flow streams? • What is the difference between an annuity due and an ordinary annuity?
Annuity Example • If you started at age 19 to save 2,000 per year at the end of the year and could average 11% per year in earnings, how much would you have at retirement at age 65?
Would it make a difference if you started at the beginning of the year instead of the end? How much?
