- 3. See your standingGet the percentile by two methods, your top share and students beaten.
Formulas used
With rank r among N students, and e students sharing your rank, the number of students below you is B = N − r − e + 1.
Percentile (at or below) = (B + e) ÷ N × 100. This is the style used by NTA, which counts students with a score equal to or lower than yours.
Percentile rank (mid-point) = (B + ½e) ÷ N × 100. This is the textbook definition, which counts half the ties.
Worked example with the defaults: rank 12 of 180 with no ties. B = 168. At-or-below percentile = 169 ÷ 180 = 93.89. Mid-point percentile = 168.5 ÷ 180 = 93.61. You are in the top 12 ÷ 180 = 6.67%.
Percentile to rank
To go the other way, the tool uses rank ≈ (100 − percentile) ÷ 100 × N, rounded up. With a percentile of 93.5 among 180 students, the rank is about 12. Ties and rounding mean the real rank can differ slightly.
Percentile is not the same as percentage. A percentage is your marks out of 100; a percentile tells you how many people scored at or below you. Exams define percentile in their own way, so read the official method for a national exam. To find percentiles of a full list of scores, use the percentile calculator.
Frequently asked questions
Is percentile the same as percentage?
No. A percentage is your share of the marks. A percentile shows your position compared with other students.
Why are there two percentile figures?
Different sources treat ties differently. The NTA style counts everyone at or below your score; the mid-point method counts half of those tied with you.
Can I use this for JEE or CUET?
You can get a rough idea, but those exams publish their own percentile method and normalisation. Use the official figures.
Is this tool free?
Yes. You enter your name and WhatsApp number once when you see your result, and other Uncodemy tools then open without the form.
