What is Percentile Calculator?

Percentile Calculator helps you locate a score within the distribution of values you provide.

The main result is cohort percentile estimate. The formula, example and assumptions below explain how to interpret it.

How to use Percentile Calculator

Use the example to get familiar with the form, then enter your own figures. Any rates in the example are illustrative. Check the field labels and units before calculating.

  1. Gather candidates scoring at or below your score and total candidates in the same cohort / session. Use values from the same situation or reporting period.
  2. Replace the example candidates scoring at or below your score with your own value, then complete the other fields. Check the displayed units.
  3. Select Calculate and read cohort percentile estimate. Change one input and calculate again to compare a second scenario. Reset restores the original example.
  • Enter candidates scoring at or below your score, at least 0. Use a whole number.
  • Enter total candidates in the same cohort / session, at least 1. Use a whole number.

Understanding the Percentile result

The main output is cohort percentile estimate, expressed in %. It applies to the inputs and operation you selected.

Displayed results use a readable number of decimal places. When checking a result by hand, keep extra precision until the last step. To compare scenarios, change one input at a time and keep the others fixed.
