The QUARTILE.EXC function returns the quartile of the data set, based on percentile values from 0…1, exclusive.

  • This function was introduced in Excel 2010 and so is not available in earlier versions.




Argument Description
array The range of data values for which you want to calculate the specified quartile
quart An integer between 1 and 3, representing the required quartile

  If quart = 1 or 3, the supplied array must contain more than 2 values

Note: The QUARTILE.EXC function can’t calculate the 0’th or the 4’th quartile as the calculation is based on the range 0 to 1 exclusive.

If the requested quartile falls between two of the values in the supplied array, Excel interpolates between these values to calculate the quartile value.


  A B C D E
1 Data   Formula Result Notes
2 9   =QUARTILE.EXC(A2:A10,1) 11.5 Locates the position of the first quartile
3 37   =QUARTILE.EXC(A2:A10,2) 20 Locates the position of the second quartile
4 6   =QUARTILE.EXC(A2:A10,3) 32 Locates the position of the third quartile
5 16        
6 26        
7 32        
8 32        
9 14        

Note: The Quartile.Inc function is closely related to the PERCENTILE.EXC 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

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 < 1 or > 3
  the supplied array is empty
  the supplied array has fewer than 3 values, and quart is 1 or 3

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.
