The Excel PERCENTILE Function


In Excel 2010, the PERCENTILE function has been renamed the Percentile.Inc function.

Although it has been replaced, the Percentile function is still available in current versions of Excel (stored in the list of compatibility functions), to allow compatibility with earlier versions of Excel.

However, the Percentile function may not be available in future versions of Excel, so it is advised that you use the Percentile.Inc function if possible.
