Hi,

The calculation of JEE mains percentile follows a normalization process . Basically, your raw score is calculated which is then compared with others and then a comparative figure is calculated which is determined by: 100* (no.of students who scored more than or equal to you/  total no. of students)

You can refer to this for more details: https://engineering.careers360.com/articles/jee-main-marks-vs-percentile

I hope this helped you.
