How to Calculate Percentile in JEE Mains 2025 from NTA Score: If you’re preparing for JEE Mains 2025, understanding how to calculate your percentile from your NTA score is crucial. The National Testing Agency (NTA) follows a specific normalization process to calculate percentiles, ensuring fairness across different shifts. Unlike traditional percentage calculations, the percentile score is a relative ranking system that shows where you stand among all test-takers. Let’s dive into the complete method to calculate your JEE Mains percentile in an easy and human-friendly way.

Understanding Percentile Score in JEE Mains
The percentile score is not the raw marks you score in the exam but a value that represents your relative performance compared to other students. It is based on the number of candidates who scored equal to or less than you in your session. The formula used by NTA to calculate the percentile is:
Percentile Score = (Total number of candidates in the session who scored equal to or less than you / Total number of candidates in the session) × 100
This means if your percentile is 90, you performed better than 90% of the students in your session. Since JEE Mains is conducted in multiple shifts, NTA uses a normalization process to account for variations in difficulty across different slots.
Step-by-Step Process to Calculate Your JEE Mains Percentile
Step 1: Identify Your NTA Score
Your NTA Score is the normalized score given by NTA after considering variations in the difficulty level of different sessions. This score is provided in your result sheet.
Step 2: Determine the Number of Candidates Below You
NTA considers how many students scored equal to or below your score in your session. This data is provided in official statistics released by NTA after the exam.
Step 3: Use the Percentile Formula
Once you have the total number of students and the number of students below you, apply the formula:
Percentile Score = (Candidates below you / Total candidates in your session) × 100
For example, suppose 50,000 students appeared in your session, and your rank (based on raw marks) is 5,000. Then, the number of candidates below you is:
50,000 – 5,000 = 45,000
Now, apply the formula:
Percentile Score = (45,000 / 50,000) × 100 = 90.00
This means your percentile score is 90.00.
Key Points About JEE Mains Percentile Calculation
- Percentile is Different from Percentage: Many students confuse percentile with percentage. A percentile of 90 does not mean you scored 90% of the total marks but rather that you performed better than 90% of students.
- Multiple Sessions & Normalization: Since JEE Mains is held in multiple sessions, your raw marks are first converted into a normalized NTA score, which is then used to calculate your final percentile.
- Higher Marks = Higher Percentile: The more marks you score, the higher your percentile will be. However, a small difference in marks at higher scores can cause significant percentile fluctuations.
- Final Rank Calculation: Your All India Rank (AIR) is determined based on your final percentile score. If multiple students have the same percentile, tie-breaking rules are applied based on their subject-wise scores.
Expected JEE Mains Percentile vs. Marks (Approximate)
To give you a rough idea, here is an estimated correlation between JEE Mains marks and percentiles:
- 250+ Marks → 99+ Percentile
- 220 – 250 Marks → 98 – 99 Percentile
- 180 – 220 Marks → 95 – 98 Percentile
- 150 – 180 Marks → 90 – 95 Percentile
- 120 – 150 Marks → 85 – 90 Percentile
- 90 – 120 Marks → 75 – 85 Percentile
- Below 90 Marks → Below 75 Percentile
Keep in mind that these are approximate values and can change based on the overall performance of students in a given year.
Frequently Asked Questions (FAQs)
Q1: How is the JEE Mains percentile different from my raw score?
A: Your raw score is the actual marks you obtain based on correct and incorrect answers, while the percentile score is a relative ranking based on how many candidates scored lower than you.
Q2: How does normalization affect my percentile?
A: Since JEE Mains is conducted in multiple shifts, normalization ensures fairness by adjusting scores based on the difficulty level of each session, so no student is at a disadvantage.
Q3: Can my percentile decrease if others perform better?
A: Yes, percentile is a comparative score. If a large number of students score higher, your percentile might decrease even if your marks remain the same.
Q4: Is there a fixed marks-to-percentile conversion?
A: No, the conversion varies every year based on overall student performance and difficulty levels.
Q5: Can two students have the same percentile?
A: Yes, in such cases, NTA applies tie-breaking criteria based on subject-wise scores.
Conclusion
Calculating your JEE Mains 2025 percentile from your NTA score is straightforward once you understand the process. The percentile score is a ranking mechanism that tells you how you performed relative to other candidates in your session. Since multiple sessions exist, normalization ensures fairness in the calculation. By understanding how percentiles are derived, you can estimate your performance and plan your preparation accordingly. Keep practicing, stay focused, and aim for a high percentile to secure admission to your dream engineering college. Best of luck with your JEE Mains 2025 journey! 🚀
