How the CAT Percentile Calculator works
Educational percentile from rank
CAT reports section-wise and overall percentiles from scaled scores after equating across slots. The exact equating model is not fully published as a student-facing closed formula. This tool uses educational rank-based percentile: 100 × (1 − (rank − 1) / N).
Educational approximation — CAT scaled-score equating is proprietary to the convenor IIM. Official percentiles appear only on the CAT scorecard.
About Common Admission Test
CAT is the gateway exam for IIMs and many other MBA programmes. Scores are scaled across morning/afternoon slots; a raw score in one slot is not comparable to another slot’s raw score without that year’s equating.
One test day with multiple slots, usually late November.
What this tool does not do
This is not a CAT rank predictor and does not invent cutoffs. Enter your own session or rank stats; the math is shown step by step.
Frequently asked questions
Is this an official CAT calculator from IIMs (rotating convenor IIM)?
No — it is a free Knwdle helper. Methodology follows published public concepts (educational rank-based percentile) and cites sources on the page. Always trust your official scorecard.
Does this predict CAT ranks or college cutoffs?
No. We deliberately do not ship rank predictors or fake cutoffs. Percentile tools only compute transparent relative-standing maths from numbers you enter.
What is unique about CAT?
CAT is the gateway exam for IIMs and many other MBA programmes. Scores are scaled across morning/afternoon slots; a raw score in one slot is not comparable to another slot’s raw score without that year’s equating.
Why is this labeled an educational approximation?
Educational approximation — CAT scaled-score equating is proprietary to the convenor IIM. Official percentiles appear only on the CAT scorecard.
Can I change the exam date on the countdown?
Yes — the countdown date is always editable. The prefilled 2026-11-29 is an example only (Example only — CAT is typically the last Sunday of November; edit after the convenor IIM announces the date.).
