How accurate is the percentile to rank formula?

It is highly accurate (within 1-3%) when the total number of unique candidates is known accurately.

What is CRL in JEE Main?

CRL stands for Common Rank List. It is the unreserved All India merit list of all students who took the exam regardless of their category.

JEE Main Percentile to Rank Estimator

Calculate your estimated All India Common Rank List (CRL) and Category rank from your JEE Main NTA percentile score.

NTA Percentile Score (0 – 100)

Total Candidates AppearedApprox 14.5 Lakh unique aspirants in recent sessions.

CategoryCategory rank is approximated from demographic shares.

Estimated Common Rank List (CRL)

#21,751

Estimated CRL Range: #20,011 – #23,491

Category Rank (OPEN)

Same as CRL

Based on ((100 - P) / 100) × 14,50,000 formula.

This rank is a statistical estimate based on the formula ((100 - Percentile) / 100) * Candidates. Official ranks are determined exclusively by NTA using subject tie-breaker rules and normalization.

JEE Main Percentile to All India Rank (CRL) Formula

Your All India Rank (CRL) is derived from your NTA percentile by calculating how many unique candidates scored higher than you across all sessions.

Estimated CRL Rank = Math.floor(((100 - Percentile) / 100) * Total Unique Candidates) + 1

Calculation Steps

1Subtract your NTA percentile from 100 to determine the top percentage of test takers.
2Multiply by the total number of unique candidates who appeared across both Session 1 and Session 2.
3Add 1 to determine your exact rank standing.
4For Category Rank, apply the statutory reservation seat and candidate proportion factor (OBC ~27%, EWS ~10%, SC ~15%, ST ~7.5%).

Practical Example

Scenario: Candidate with 99.20 percentile and 14,50,000 unique test takers

Inputs: NTA Percentile: 99.20 | Total Candidates: 14,50,000

Calculation: ((100 - 99.20) / 100) * 1,450,000 + 1 = 0.008 * 1,450,000 + 1 = 11,600 + 1

Result: Estimated All India CRL Rank: ~11,601 (Margin of error ±500)

Assumptions & Disclaimers

Key Assumptions:

Total unique candidates across both sessions estimated at 14,50,000.
NTA tie-breaking rules (higher marks in Math > Physics > Chem > Age) are not simulated.

Rank predictions are mathematical projections. Final official All India Common Rank List (CRL) and Category ranks are announced exclusively by the NTA after Session 2 results are declared.
