The QUARTILE.INC function returns the quartile of a data set, based on percentile values from 0…1, inclusive.

  • This function was introduced in Excel 2010 and so is not available in earlier versions.
  • The QUARTILE.INC function replaces the QUARTILE function included in earlier versions of Excel.




Argument Description
array The range of data values for which you want to calculate the specified quartile
quart An integer between 0 and 4, representing the required quartile

  If quart equals QUARTILE.INC returns
  0 Minimum value
  1 First quartile (25th percentile)
  2 Median value (50th percentile)
  3 Third quartile (75th percentile)
  4 Maximum value

Note: The Quartile.Inc function is closely related to the PERCENTILE.INC such that:

  • The 1st quartile is the same as the 25th percentile
  • The 2nd quartile is the same as the 50th percentile
  • The 3rd quartile is the same as the 75th percentile
  • The 4th quartile is the same as the 100th percentile – the maximum value in the range

Common Function Error(s)

Problem What went wrong
#VALUE! Occurs if the supplied value of quart cannot be interpreted as a numeric value
#NUM! Occurs if either:

  the supplied value of quart is is < 0 or > 4
  the supplied array is empty

The 1st, 2nd, 3rd or 4th quartile of a range of data is the value that 25%, 50%, 75% or 100% (respectively) of the data values fall within.

The QUARTILE.INC and QUARTILE.EXC functions both find a requested quartile of a supplied data set. The difference between these two functions is that the QUARTILE.INC function bases its calculation on a percentile range of 0 to 1 inclusive, while the QUARTILE.EXE function bases its calculation on a percentile range of 0 to 1 exclusive.
