How to use GEOMEAN Function in Excel

The Excel GEOMEAN function returns the geometric mean for a set of numeric values. Geometric mean can be used to calculate average rate of return with variable rates.

Syntax:=GEOMEAN (number1, [number2], …)

The GEOMEAN function syntax has the following arguments:

  • Number1, number2, …    Number1 is required, subsequent numbers are optional. 1 to 255 arguments for which you want to calculate the mean. You can also use a single array or a reference to an array instead of arguments separated by commas.

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

Syntax:  =GEOMEAN(A2:G2)

Result: 5.47698697

Based on the Excel spreadsheet above, the following GEOMEAN examples would return:

Syntax: =GEOMEAN(A3:G3)
Result: 2.393483066

Syntax: =GEOMEAN(A4:F4)
Result: 5.440086846

Syntax: =GEOMEAN(A5:D5)
Result: 6.160140576

Syntax: =GEOMEAN(A6:E6)
Result: 7.200411487

Syntax: =GEOMEAN(A7:G7)
Result: 34.86198727

Cells containing Text values, logical values, or no value are ignored by Excel GEOMEAN Function.


  • Arguments can either be numbers or names, arrays, or references that contain numbers.
  • Logical values and text representations of numbers that you type directly into the list of arguments are counted.
  • If an array or reference argument contains text, logical values, or empty cells, those values are ignored; however, cells with the value zero are included.
  • Arguments that are error values or text that cannot be translated into numbers cause errors.
  • If any data point ≤ 0, GEOMEAN returns the #NUM! error value.
  • The equation for the geometric mean is:
