The Excel PERCENTRANK.INC function returns the relative rank of a value in a data set as a percentage representing the number of values less than or equal to the value. Percentile rank is commonly used as a way to interpret standing in standardized tests.

**Syntax**:= PERCENTRANK.INC (array, x, [significance])

The PERCENTRANK.INC function syntax has the following arguments:

**Array**Required. The array or range of data with numeric values that defines relative standing.**X**Required. The value for which you want to know the rank.-
**Significance**Optional. A value that identifies the number of significant digits for the returned percentage value. If omitted, PERCENTRANK.INC uses three digits (0.xxx).

**Example**: Let’s look at some Excel PERCENTRANK.INC function examples and explore how to use the PERCENTRANK.INC function as a worksheet function in Microsoft Excel:

**Syntax**: =PERCENTRANK.INC($B$2:$B$17,B2)

**Result**: 0.866

Based on the Excel spreadsheet above, the following PERCENTRANK.INC examples would return:

**Syntax**: =PERCENTRANK.INC($B$2:$B$17,B3)

**Result**: 0.666

**Syntax**: =PERCENTRANK.INC($B$2:$B$17,B4)

**Result**: 0

**Syntax**: =PERCENTRANK.INC($B$2:$B$17,B5)

**Result**: 0.266

**Syntax**: =PERCENTRANK.INC($B$2:$B$17,B6)

**Result**: 0.533

**Syntax**: =PERCENTRANK.INC($B$2:$B$17,B7)

**Result**: 1

**Syntax**: =PERCENTRANK.INC($B$2:$B$17,B8)

**Result**: 0.2

**Syntax**: =PERCENTRANK.INC($B$2:$B$17,9.3)

**Result**: 0.906

**Syntax**: =PERCENTRANK.INC($B$2:$B$17,7.7)

**Result**: 0.366

**Syntax**: =PERCENTRANK.INC($B$2:$B$17,8.8)

**Result**: 0.84

**Syntax**: =PERCENTRANK.INC($B$2:$B$17,B12,2)

**Result**: 0

**Syntax**: =PERCENTRANK.INC($B$2:$B$17,B13,2)

**Result**: 0.33

**Syntax**: =PERCENTRANK.INC($B$2:$B$17,B14,2)

**Result**: 0.66

**Syntax**: =PERCENTRANK.INC($B$2:$B$17,B15,1)

**Result**: 0.9

**Syntax**: =PERCENTRANK.INC($B$2:$B$17,B16,1)

**Result**: 0.6

**Syntax**: =PERCENTRANK.INC($B$2:$B$17,B17,1)

**Result**: 0.4

**Note**:

- If x does not match one of the values in array, PERCENTRANK.INC interpolates to return the correct percentage rank.
- If array is empty, PERCENTRANK.INC returns the #NUM! error value.
- If significance < 1, PERCENTRANK.INC returns the #NUM! error value.
- If the supplied x is smaller than the minimum, or greater than the maximum value in the supplied array, PERCENTRANK.INC returns the #N/A error value.
