CAT Rank to Percentile Calculator 2026 (With the Real N)
CAT percentile is ((N − your rank) ÷ N) × 100, where N is the number of candidates who appeared, not the number who registered. For CAT 2025 that was about 2.58 lakh. For CAT 2026 nobody knows N yet: about 2.84 lakh have registered (press report, October), and if the same share turns up as last year (87.5%), roughly 2.5 lakh will appear. The calculator below shows all three.
Why N is the number that matters
Registrations are the headline number, and they’re the wrong one. In 2025, 2.95 lakh people registered for CAT but only about 2.58 lakh sat the exam, which is 87.5%. Percentile is calculated against the people who actually appeared.
For 2026, registrations are reported at about 2.84 lakh (Indian Express via Careers360, October 2026). Apply last year’s 87.5% and you get about 2.49 lakh. Attendance was 88% in 2023, 89% in 2024 and 86 to 87% in 2025, which puts the plausible range at roughly 2.44 to 2.53 lakh, and 2.49 sits in the middle. That’s our projection, not an official figure; IIM Indore will publish the real number with the result, after the 29 November exam.
It changes the answer more than you’d expect. A rank of 1,00,000 converts to 61.2 percentile at 2.58 lakh, 59.8 at 2.49 lakh and 64.8 at 2.84 lakh: a gap of about five percentile points from the same rank.
What this calculator can’t tell you
Two honest limits. First, CAT’s scorecard gives you a percentile, not a rank, so any rank you have came from a mock-test platform or a predictor. Treat it as an estimate. Second, a bigger N doesn’t only change the formula; it also changes where a given score lands. If more people appear, the same performance usually sits further down the list, so your rank gets worse as N grows. The number that counts is the percentile on your scorecard, due between late December and the first week of January (here’s the likely date).
Common ranks, converted
| Rank | Percentile at N = 2.58 lakh | At N = 2.49 lakh (projection) | Colleges |
|---|---|---|---|
| 10,000 | 96.1 | 96.0 | Colleges for a 10,000 rank |
| 20,000 | 92.2 | 92.0 | Colleges for a 20,000 rank |
| 30,000 | 88.4 | 88.0 | Colleges for a 30,000 rank |
| 50,000 | 80.6 | 79.9 | Colleges for a 50,000 rank |
| 75,000 | 70.9 | 69.9 | Colleges for a 75,000 rank |
| 1,00,000 | 61.2 | 59.8 | Colleges for a 1,00,000 rank |
| 1,50,000 | 41.9 | 39.8 | Colleges for a 1,50,000 rank |
Percentile bands and the colleges that admit in each are in CAT percentile vs colleges. For what a rank means in the first place, see CAT rank vs college, and for the conversion the other way round (percentile to rank), see CAT percentile vs rank.
Questions people ask
How is CAT percentile calculated?
Percentile = ((N − rank) ÷ N) × 100, where N is the number of candidates who appeared. For example, rank 50,000 with N = 2.58 lakh gives about 80.6 percentile.
How many candidates appeared in CAT 2025?
About 2.58 lakh, out of 2.95 lakh registered, which is roughly 87.5%.
How many candidates will appear in CAT 2026?
Not known until after the 29 November exam. About 2.84 lakh have registered (press report, October 2026); at last year’s attendance, about 2.5 lakh would appear. That is a projection.
Does CAT publish a rank?
The scorecard shows overall and section-wise percentiles and scaled scores, not a rank. Ranks you see come from mock platforms or predictors.
Is the registered number the same as N?
No. N is the number who appeared. Using registrations understates your percentile.
Where this comes from
2025 registered and appeared counts are from Cracku; the 2026 registration figure (about 2.84 lakh) is from Careers360, citing the Indian Express. The scorecard contents are from MBAUniverse. The 2026 N is our projection.
