Class Rank Percentile Calculator by TheCalcTools

How the Class Rank Percentile Calculator works

‘Top X%’ = rank ÷ class size × 100. The percentile is the share of the class ranked below you: (class size − rank) ÷ class size × 100.

Colleges and scholarships sometimes ask for a top 10% or top 25% rank. Ties and weighted grades are handled differently by each school.

The formula

Top % = rank ÷ size × 100; percentile = (size − rank) ÷ size × 100

Using the default values shown in the calculator:

Your rank (1 = top)37
