How to calculate JEE Main 2021 rank based on NTA Percentile score?

So, to convert your JEE Main Percentile into a Rank, you need the following figures:

  1. Your NTA score
  2. Total number of students who have appeared for the exam
  3. Percentage of students below or equal to your marks
  4. Percentage of students above your marks
  5. Number of students above your marks

 While the data for the first two aspects are easily available, the figures for the other three data points is difficult to find. To calculate these, here’s what you need to do.

Let’s suppose:

Your NTA score = P
Total Number of Students = N
Percentage of students below or equal to your marks = P


Example: if you have secured a 70 percentile in JEE Main, which means that 70% of the candidates who appeared for JEE Main are below or at the same level as you are

Percentage of students above your marks = 100 – P
Number of students above your marks ((100 – P)/100)*N

Formula to calculate JEE Main 2021 Rank from Percentile Score

Now, the formula to calculate JEE Main 2021 Rank from Percentile Score is: [(100 – P)/100)]*N + 1

The rank generated will be the probable All India Rank you can expect to secure in JEE Main 2021. The actual rank might differ owing to different factors.

Let us see an example here:

Two Candidates X & Y both appeared for the JEE Main 2021 in January and April as well. If candidate X gets 94 percentile in January and 65 percentile in April. Whereas, the student Y gets 80 percentile in January and 98 percentile in April.

  • For the 8 students with percentile 90 in Shift 1 and percentile 90 in Shift 2 and so on… the tie-breaker will be on the basis of
  • Percentile in Math followed by
  • Percentile in Physics followed by
  • Percentile in Chem followed by
