About the Percentile Calculator

The Percentile Calculator finds the percentile rank of a value within a dataset, or finds the value at a chosen percentile. It is useful for test scores, growth charts, salaries and any ranked data.

The percentile rank tells you the percentage of data points that fall below a value. If you score at the 90th percentile, you did better than about 90 percent of the group. There are several definitions of percentile in statistics, so results can differ slightly between tools, especially for small datasets.

How to use it

  1. Enter your data separated by commas or spaces.
  2. Enter a value to find its percentile rank, or a percentile to find its value.
  3. Read the result.
  4. Compare with expected ranges.
