Calculated column
Calculated table
Measure
Visual calculation
Returns the geometric mean of the numbers in a column.
To return the geometric mean of an expression evaluated for each row in a table, use GEOMEANX function.
Syntax
GEOMEAN(<column>)
Parameters
| Term | Definition |
|---|---|
| column | The column that contains the numbers for which the geometric mean is to be computed. |
Return value
A decimal number.
Remarks
Only the numbers in the column are counted. Blanks, logical values, and text are ignored.
GEOMEAN( Table[Column] ) is equivalent to GEOMEANX( Table, Table[Column] )
This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules.

The following computes the geometric mean of the Return column in the Investment table:
= GEOMEAN( Investment[Return] )
