Go to how fast will your savings grow, at
http://cgi.money.cnn.com/tools/savingscalc/savingscalc.html
  and check how much your money could grow if you enter the number of years.
Play with several of the values like savings per month and expected rate of return and notice how the number of yours changes.

1. What happens to the length of time it takes you to become a millionaire when you increase your savings per month?
2. What happens when you increase the expected rate of return?
3. How do taxes impact your accumulation? Why are marginal tax rates important instead of average?
4. What rate should you use for an expected return?
5. What should you do if you want to become a millionaire sooner than the calculator indicates?

Each of you have DIFFERENT conditions and constraints.
You do not need to answer all five. Answer any one, two, at most three(3).
Comment on one of your peers also.
