## Excel PERCENTILE function and Excel PERCENTRANK function: Overview

Excel 2013 has *four* options for finding a percentile. Which one you use depends on what you want to do. In previous editions of Excel there were two percentile functions: PERCENTRANK and PERCENTILE. The Excel PERCENTRANK function gave you a percentile for a particular rank, while PERCENTILE returned the particular score from a list. In Excel 2013 there are now **four** options:

- PERCENTILE.INC Finds a score given a percentile. For example, you can ask Excel to find
**what score is in the 50th percentile.**The “INC” part of the function means to include 0% and 100% in the tallies. - PERCENTILE.EXC is exactly the same as PERCENTILE.INC with one difference: 0% and 100% are excluded. For example, it will calculate the 99th percentile but not the 100th percentile.
- PERCENTRANK.INC will return the ranking for a particular data item. for example, if you have a list of scores for a test, the function will give you a percentage ranking (i.e. 99th percent) for a particular data item. In other words,
**if you have a score of, say 50 on a test, you can find out what your ranking is. It included 0% and 100%.** - PERCENTRANK.EXC is exactly the same as PERCENTRANK.INC but it excludes 0% and 100%
