I believe the formula for this is  B*R=P
Percentage = Base x Rate
Base = Percentage / Rate
Rate = Percentage / Base 
I wish i could help you more than that, but i'm short of doing this as well. 
Base = the number you start with.
Rate = the % (like) 6% or .06
Percentage = the number you end up with.
Sorry, this is the best i can do.
