Hello Vaibhav,

You can use the formulae given below to claculate your rank -

Rank Formula = (100 - your total score) X 874469 /100. 

874469 are the number of candidates appeared for JEE mains 2019 January attempt.

All the best!

Thanku.

You score good Percentile score.But it will be difficult to predict raw score from percentile score as it only tells about relative performance of the candidates in their respective session.I can give you rough idea about your rank in general category.Your rank will be around 22.3k.It is good rank through this rank you will get lot of NIT through seat allocation program.

For assurance wait till NTA decalres rank.NTA will declares rank after 2nd phase of jee mains 2019.

GOOD LUCK!
