The percentile formula calculator will find the score for the desired percentile for a data set.  First, enter the data set and desired percentile and you’ll get the answer. Then, you will get a step-by-step explanation on how to do it yourself.  The desired percentile represents the percent of numbers in the data set that have values at or below the number that we’ll calculate.

Afterward, see the Percentile Calculator if you have a score and need to find its percentile rank.  You GOT this!
