user11288: 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? 

user7897: 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.
