How do I get my FIDE percentile? How do I get the percentile rating? 

This is the rank:   

World (all players):    97112
World (active players): 45540

How many players are there in the world that are members of FIDE?
According to this question on quora.com, there are ~486,000 players as of January 2015.  (They reference a FIDE rating list here.)  Not an exact number, but most likely close enough for percentile purposes.

If you're not sure how to calculate a percentile rating, I found this question, which gives the following formula:

R = P / 100 (N + 1)


... where R represents the rank order of the score, P represents the percentile rank, and N represents the number of scores.
