In this program you will be asked to enter:

• An amount to save/invest each month
  
• The interest rate you earn on your savings/investments
  
• The number of months you save/invest for
  

and the program will calculate the amount of money you have
in your nest egg at the end.
This assumes that you make a contribution at the end of month 0
(which is the start of month 1) and at the end of each month.
In 5 years you will make 60 contributions.
