Excel find the percentile of a number using PERCENTRANK.EXC function

This Excel tutorial explains how to find the percentile of a number from an array using PERCENTRANK.EXC function.

Excel Percentile

Percentile is a statistics term used to describe the Nth observation in a data set after sorting in ascending order. For example, 40th percentile (P40) refers to the approximately 40th data of the 100 data. If the data set is not exactly 100, say 200, we find the location of observation at 40% of total data.

Some companies may have salary guideline of P75, which means they generally pay better than the market in order to attract and retain talents. Percentile is a better measure than average because extreme data are disregarded using percentile.
