This JEE Main percentile calculator turns your right and wrong answers into a score out of 300, then into an approximate percentile band and rank range. If you know how many candidates in your shift scored at or below you, it also gives the exact NTA percentile to seven decimals. No sign-up, nothing stored.

Enter your counts and press Calculate score. You'll get marks by subject, an approximate percentile band and a rank band.
Exact percentile
Useful once shift-wise data is out. Before that, the approximate band above is the better guide.
Where a score out of 300 usually lands. The percentile column is the part this calculator estimates; rank is (100 − percentile) ÷ 100 × about 14 lakh candidates.
| Marks (out of 300) | NTA percentile | All-India rank (CRL) |
|---|---|---|
| 250–300 | 99.96–100.00 | 1 – 620 |
| 220–249 | 99.87–99.96 | 660 – 2,000 |
| 200–219 | 99.75–99.86 | 2,100 – 3,900 |
| 180–199 | 99.55–99.74 | 4,000 – 6,900 |
| 160–179 | 99.25–99.53 | 7,200 – 12,000 |
| 140–159 | 98.80–99.23 | 12,000 – 18,000 |
| 120–139 | 98.00–98.76 | 19,000 – 31,000 |
| 100–119 | 96.60–97.93 | 32,000 – 52,000 |
| 80–99 | 94.00–96.49 | 54,000 – 92,000 |
| 60–79 | 89.50–93.80 | 95,000 – 1,62,000 |
| 40–59 | 80.50–89.15 | 1,67,000 – 3,00,000 |
| 20–39 | 55.00–79.55 | 3,15,000 – 6,93,000 |
| 0–19 | 8.00–52.50 | 7,32,000 – 14,17,000 |
Approximate, based on 2024–2026 results and published analyses. The same marks can map to a different percentile in a different shift. Not official NTA data.
BrainStride is an AI tutor for JEE, NEET and Olympiad preparation that runs a 20-minute diagnostic, maps your weak chapters and writes a daily plan, with every solution checked by teachers. This calculator is the free, no-account part: your score, and what it probably means.
Since 2025, JEE Main Paper 1 has 75 compulsory questions — 25 each in Physics, Chemistry and Mathematics, each subject with 20 MCQs and 5 numerical-value questions. Every correct answer is +4 and every incorrect answer is −1, for MCQs and numericals alike. Unattempted questions score 0. So 18 right and 4 wrong in Physics is 72 − 4 = 68 marks.
NTA does not rank raw marks. Inside each shift it calculates:
NTA percentile = 100 × (candidates in the shift with a raw score equal to or below yours) ÷ (total candidates in the shift)
The result is reported to seven decimal places. The topper of every shift gets 100, which is why percentiles from an easy shift and a hard shift can be compared. If you write both sessions, the better of your two NTA scores is used for your rank.
Suppose 1,20,000 candidates sat your shift and 1,18,560 of them scored equal to or below you. Your NTA score is 100 × 1,18,560 ÷ 1,20,000 = 98.8000000. If 1,19,988 scored at or below you, it is 99.9900000. If you were the shift topper, every candidate scored at or below you and the score is 100.
Now suppose a friend with the same raw marks sat an easier shift of 1,20,000 where only 1,17,600 scored at or below them: 100 × 1,17,600 ÷ 1,20,000 = 98.0000000. Same marks, lower percentile — which is the point of the formula. It measures where you stood in your shift, and that is what makes shifts comparable.
On our curve from the 2024–2026 sessions, 150 marks sits around the 99.0 percentile, 120 around 98.0 and 100 around 96.6, each moving a point or so either way with the shift. The full every-5-marks table and one-line answers for every score are on the marks vs percentile vs rank page; this calculator is for your own correct/incorrect count and for the exact formula once shift data is out.
Before shift-wise data is out, nobody outside NTA knows how many candidates scored at or below you. So we read a marks-to-percentile curve built from published analyses of the 2024–2026 sessions, 6 marks below and above your score. That spread stands in for the difference between shifts.

After you get your score
Count right and wrong answers per subject against your recorded responses when NTA releases the provisional key. Scoring from memory tends to overstate marks.
In 2025, General candidates needed the 93.1023262 percentile to write JEE Advanced. Compare your band with the cutoff for your category.
Every wrong answer costs five marks against getting it right. If one subject shows more than five negatives, that is the fastest percentile you can win back.
Use the rank predictor with the same marks to see where the band sits for JoSAA, then re-run it after every mock.
JEE Main percentile is calculated inside each shift as 100 × the number of candidates in that shift with a raw score equal to or below yours ÷ the total number of candidates in the shift. NTA reports it to seven decimal places. It is a relative score, so the same marks can give a different percentile in an easier or harder shift.
In the 2024 and 2025 JEE Main sessions, 150 marks out of 300 usually meant roughly the 98.9–99.2 percentile, which works out to an all-India rank of about 12,000–16,000. That is an approximate band from published analyses, not an NTA figure. A tougher shift pushes the same marks towards the top of the band.
No. A JEE Main percentage would be your marks out of 300, while the JEE Main percentile shows the share of candidates in your shift who scored at or below you. 150 marks is 50% of the paper but, in recent sessions, close to the 99th percentile, because most candidates score far lower.
Yes. Since JEE Main 2025, all 75 questions are compulsory and numerical-value questions carry −1 for an incorrect answer, the same as MCQs. The optional section of 2021–2024, where you chose 5 of 10 numericals without negative marking, was removed. Unattempted questions still score zero.
If you write both JEE Main sessions, NTA uses the better of your two NTA scores for the all-India rank. Each session percentile is calculated separately within its own shift. Writing Session 2 cannot lower your rank, but it only helps if you beat your Session 1 percentile.
Only if you know two numbers for your shift: how many candidates scored at or below you and how many wrote the shift. NTA does not publish those before the result, so any percentile before then — including this JEE Main percentile calculator’s band — is an estimate built from past sessions.
The percentile formula and marking scheme follow NTA’s information bulletin. The marks-vs-percentile curve is our approximation from 2024–2025 published analyses, not NTA data.
