Percentile Rank Calculator

Calculate percentile rank of a value within a dataset

Calculate Percentile Rank

Enter numbers separated by commas, spaces, or line breaks

The value doesn't need to be in your dataset

Example Calculation

Test Scores Example

Dataset: 6, 12, 13, 17, 17, 18, 20, 23, 24, 24, 25, 26, 27, 27, 30, 32, 33

Your score: 25

Total students: 17

Students scoring ≤ 25: 11

Calculation

PR = (L / N) × 100

PR = (11 / 17) × 100

PR = 64.7%

This means you scored better than or equal to 64.7% of students.

Understanding Percentile Rank

What is Percentile Rank?

Percentile rank indicates the percentage of values in a dataset that are less than or equal to a specific value. It's a way to understand where a particular value stands relative to others in the same dataset.

Applications

  • Educational assessment and test scoring
  • Medical growth charts and health metrics
  • Performance evaluation and benchmarking
  • Financial analysis and market research

Formula Explanation

PR = (L / N) × 100

  • PR: Percentile rank (0-100)
  • L: Number of values ≤ target value
  • N: Total number of values in dataset

Example: If you score better than 75% of test takers, your percentile rank is 75, meaning you're in the 75th percentile.
