How to calculate percentile rank
Percentile rank shows what percentage of observations in a dataset fall below a specific score — a standard way to express relative standing within a distribution.
How the calculation works
Percentile rank = (Values below score ÷ Total observations) × 100.
Example
340 values below a given score out of 400 total observations: (340÷400)×100 = 85%, meaning this score is at the 85th percentile.

Pro Tips for Percentile Rank
- A percentile rank of 50 means the value is at the median — exactly half of observations fall below it.
- Percentile rank describes relative standing within a specific dataset, not an absolute measure — the same raw score could have a different percentile rank in a different dataset.
Common Percentile Rank Mistakes to Avoid
- Treating percentile rank as a fixed, absolute property of a score, when it's actually relative to the specific comparison group or dataset being used.
