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
Worked example
Using the default values shown in the calculator:
| Your rank (1 = top) | 37 |
|---|---|
| Class size | 420 |
- Rank 37 of 420 is the top 8.8%, the 91.2% percentile.
Result:
| Top percent | 8.8% |
|---|---|
| Percentile (share of the class below you) | 91.2% |
| Rank needed for the top 10% | 42 |
| Rank needed for the top 25% | 105 |
| Decile | Decile 1 (1 = top tenth) |
