Percentile Calculator
The Percentile Calculator computes your percentile rank given your score and the total number of students, or calculates what score corresponds to a given percentile. Essential for JEE, NEET, CAT, and all competitive exam results.

What Is Percentile and How Is It Calculated?
A percentile tells you what percentage of a group scored at or below your score. A 95th percentile means you scored better than 95% of the group. Percentile is NOT the same as percentage — 75% marks could be the 50th or the 99th percentile depending on how difficult the exam was and how others performed.
JEE Main uses the NTA percentile formula: NTA Percentile = 100 × (Number of candidates with raw score equal to or less than the candidate's score) ÷ (Total number of candidates). This is calculated separately for each session and then normalised across sessions.
In statistics, the percentile divides a dataset into 100 equal parts. The median is the 50th percentile. The first quartile (Q1) is the 25th percentile, and the third quartile (Q3) is the 75th percentile. These are widely used in standardised testing, growth charts, and salary surveys.
🔬 Methodology & Accuracy
Formula: Uses the standard mathematical formula shown in the Formula & Method section above. All computations run client-side in your browser — no data is sent to our servers.
Data sources: Tax bands, contribution limits and regulatory rates are taken from official US (IRS, SSA) and UK (HMRC, gov.uk) publications for the current tax year, and updated when bands change.
Last reviewed: June 2026 · Accuracy: Results are precise to two decimal places using IEEE-754 double-precision arithmetic. Intended for educational and planning use only.
