Percentile Calculator
Calculate the percentile rank of a target value from a set of comma-separated scores.
Sorted list (10 values):
76, 78, 84, 85, 88, 89, 90, 91, 92, 95
Result
Percentile Rank
55.0th percentile
Values Below Target
5 of 10
Values Equal to Target
1 of 10
Values Above Target
4 of 10
How to use the percentile calculator?
Enter a set of scores as comma-separated numbers, then enter the target value whose percentile rank you want to find. The calculator sorts the data, counts how many values fall below, equal, or above the target, and computes the percentile rank using the standard formula.
Formula
Percentile Rank = ((Number of values below target + 0.5 × Number equal to target) / Total values) × 100
Example
In the dataset 85, 90, 78, 92, 88, 76, 95, 89, 84, 91, the target value 89 has 6 values below it and 1 equal to it. The percentile rank is ((6 + 0.5 × 1) / 10) × 100 = 65.0 — meaning 89 scores higher than about 65% of the dataset.
FAQs
- What does "65th percentile" mean? A 65th-percentile score is higher than approximately 65% of the values in the dataset. It does not mean the score is 65 out of 100.
- What formula is used? This calculator uses the standard percentile rank formula: (below + 0.5 × equal) / total × 100. Other methods (e.g., below / total × 100) exist and may give slightly different results.
- Can I enter negative numbers or decimals? Yes — the calculator accepts any valid numeric values, including negatives and decimals.
Common Use Cases
- Finding a student's percentile rank on a standardized test.
- Comparing an individual score against a distribution of benchmark scores.
- Understanding where a data point falls within a dataset for performance analysis.
