For your problem, the general formula is

    Future value = 500%2A%281%2B0.11%2F12%29%5En,

where "n" is the number of months.



For example,  for 1 month  (n= 1)

    Future value = 500%2A%281%2B0.11%2F12%29%5E1 = 504.58 dollars.



Next, for 6 months

    Future value = 500%2A%281%2B0.11%2F12%29%5E6 = 528.14 dollars.



Do the rest by the same way.
