PERCENTRANK.INC & PERCENTRANK.EXC Functions

The Percentrank.Inc and Percentrank.Exc functions both calculate the relative position of a specified value, within a supplied array of values, and return this value, as a percentage.

The difference between these two functions is that the Percentrank.Inc function calculates a value in the range 0 to 1 inclusive, whereas the Percentrank.Exc function calculates a value in the range 0 to 1 exclusive.

Function Description

The Excel Percentrank.Exc function calculates the relative position, between 0 and 1 (exclusive), of a specified value within a supplied array.

The function is new in Excel 2010 and so is not available in earlier versions of Excel.

The syntax of the function is:

PERCENTRANK.EXC( array, x, [significance] )

where the function arguments are:

array - The array of values within which you want to find the relative position of a specific value.
x -

The value that you want to calculate the relative position of.

(x must be within the range of the values in the supplied array, but it does not need to be exactly equal to one of the values. If x is not found in the array, the array values are interpolated to calculate the percentage rank).
[significance] -

An optional argument that specifies the number of significant digits that the returned percentage value is rounded to.

(By default the returned percentage value is accurate to 3 significant digits).

Percentrank.Exc Function Errors

If you get an error from the Excel Percentrank.Exc function this is likely to be one of the following:

Common Errors
#N/A - Occurs if the supplied value of x is smaller than the minimum, or greater than the maximum value in the supplied array.
#NUM! -

Occurs if either:

  • The supplied [significance] value is < 1
or
  • The supplied array is empty.

Also, the following formatting problem is encountered by some users:

Common Formatting Problem

If the result of your Percentrank.Exc function is presented as a decimal, or shows 0%, this is likely to be due to the formatting of the cell containing the function.

This can therefore be fixed by formatting the cell as a percentage, with decimal places, if required.

The easiest way to format a cell to display a percentage is to select the cell(s) to be formatted and then select the percentage button from the 'Number' group on the Home tab of the Excel ribbon (see below):

Excel Format Cells As Percentage Button and Dialog Box Launcher

This uses the default percentage formatting style for your computer system which might be exactly what you require.

However, if you want to change the number of decimal places that are displayed, this can be done within the 'Format Cells' Dialog Box, which is brought up by clicking on the dialog box launcher (shown in the above image).

Excel Format Cells Dialog Box Percentage Option

Within 'Format Cells' dialog box:

  • From within the 'Category' list on the left side of the dialog box, select the Percentage type.
  • The Decimal places: option will appear in the dialog box. Use this to specify the number of decimal places that you want to display.
  • Click OK.
