Excel Percentile Function Results

Note that in the above examples:

  • The value of k can be input as a decimal or a percentage – for example, value 0.2 in cell B1, is the same as 20%, – the 20th percentile
  • The 50th percentile (see cell B3) falls between the values of 3 and 4. Therefore, Excel has interpolated, to produce the result 3.5

#NUM! Occurs if the supplied value of k is less than 0 or greater than 1
