Formula
percentile = 100 × (candidates in the session with a score equal to or lower than yours) ÷ (candidates who appeared in the session)rank (no ties) = N − (candidates at or below you) + 1
- N is the number of candidates who appeared in the session
- Ties share the best rank and the same percentile
Your percentile is the share of the session's candidates who scored no higher than you.
Worked examples
Percentile from a session rank
- What do you want to find?
- Percentile — from my rank in the session
- Candidates who appeared in the session
- 100,000
- Your rank within the session
- 1,000
Percentile
99.001%
Candidates at or below your score: 99,001
Candidates strictly above you: 999
Rank from a percentile
- What do you want to find?
- Rank — from a percentile
- Candidates who appeared in the session
- 100,000
- Percentile
- 99 %
Approximate rank
1,001
Candidates at or below that score: 99,000
Candidates ahead of you: 1,000
How it works
The National Testing Agency reports JEE Main results as a percentile calculated within each exam session. The definition is simple: take the number of candidates in your session who scored equal to or less than you, divide by the number who appeared in that session, and multiply by 100. The NTA reports the result to seven decimal places.
That definition is all this calculator applies, so it needs real figures: how many candidates appeared in your session and either your rank in it or how many scored at or below you. It can also run the other way and show the best rank a percentile corresponds to.
What it cannot do is turn raw marks into a percentile. The same marks give different percentiles in different sessions and years because the candidate pool and paper difficulty change, so any table of fixed marks-to-percentile values would be invented. To add up marks first, use the JEE Main Marks Calculator; the CAT Percentile Calculator uses the same idea for another exam.
Assumptions and limits
- Uses the definition in NTA's normalisation notes: candidates with a score equal to or lower than yours, divided by candidates appeared in the session.
- You must supply real figures for your own session. Nothing here estimates a rank from marks.
- The ranks reported by the NTA depend on the final normalised results; this tool is an arithmetic aid and not an official result.
