Class Rank Percentile Calculator

About Class Rank Percentile Calculator
Percentile counts those below while top percentage counts your position from the top, so the two are complements. Universities usually state requirements as a top percentage rather than a percentile. Rank means little without cohort size: fortieth in a class of four hundred is top ten per cent, while fortieth in a class of fifty is not.
Formula
Class Rank Percentile
Percentile = students ranked below ÷ class size × 100
- percentile
- Share of the cohort ranked below you
