## What Is GEOMEAN Function In Excel?

The

Geometric Mean or theGEOMEAN Excel functioncalculates the average growth rate or the rate of return with variable rates in a given dataset. The geometric mean is different from the arithmetic mean and is always less than the arithmetic mean/average.

The **GEOMEAN function** **in** **Excel **is an inbuilt “**Statistical**” function, so we can insert the formula from the “**Function Library**” or enter it directly in the worksheet. For example, we will calculate the **GEOMEAN function **for the values in the image below.

Select cell **B2**, enter the formula ** =GEOMEAN(A2:A3), **and press “

**Enter**”.

The result is ‘**14.142**’, as shown below.

###### Key Takeaways

- The
**GEOMEAN Excel function**calculates the geometric average/mean of an array or cell range of positive numbers that are greater than zero. - The arguments can be numbers, names, arrays, or cell references that contain numbers.
- If there are empty cells and cells that contain text or logical values, the function ignores them and calculates the rest.
- The function can take up to 255 different arguments, such as numbers, cell references, ranges, arrays, and constants.
- The mathematical formula for geometric mean is shown below, i.e., for a set of numbers [y
_{1}, y_{2}, …, y_{n}], the geometric mean is the**n**root of the product of the^{th }**n**numbers

### How To Use GEOMEAN Excel Function?

We can use the **GEOMEAN function **in 2 ways, namely,

**Access from the Excel ribbon.****Enter in the worksheet manually.**

#### Method #1 – Access from the Excel ribbon

Choose an empty cell for the output 🡪 select the **“Formulas” **tab 🡪 go to the “**Function Library**” group 🡪 click the **“More Functions” **option drop-down 🡪 click the **“Statistical”** option right arrow 🡪 select the **“GEOMEAN”** function, as shown below.

The **“Function Arguments” **window appears. Enter the arguments in the **“Number1”, **and **“Number2” **fields 🡪 click “OK”, as shown below.

#### Method #2 – Enter in the worksheet manually

- Select an empty cell for the output.
- Type =
**GEOMEAN**( in the selected cell. [Alternatively, type**=G**or**=GE**and double-click the**GEOMEAN function**from the list of suggestions shown by Excel.] - Enter the arguments as cell values or Excel cell references and close the brackets.
- Press the “
**Enter**” key.

Let us take a basic example to understand its application.

We will calculate the geometric average **using** **GEOMEAN Excel function**.

In the table, the data is,

- Column A, B, & C contains the Data.
- Column D contains the Output.

The steps to calculate **using** **GEOMEAN Excel function** are,

**Select cell D2, and enter the formula =GEOMEAN(A2:A5, i.e., the numeric value.****Enter the value of ‘number2’ as B2:B5. The formula now is =GEOMEAN(A2:A5,B2:B5,****Enter the value of ‘number3’ as C2:C5, i.e., the numeric value, and close the brackets. The complete formula is =GEOMEAN(A2:A5,B2:B5,C2:C5)****Press the “Enter” key. The result is “3.5359”, as shown below.**

### Examples

We will understand some advanced scenarios using the **GEOMEAN Excel function examples.**

#### Example #1

We will calculate the average using the **GEOMEAN function** for the data in percentage.

In the table, the data is,

- Column A contains the Rates.
- Column B displays the calculated Output.

The procedure to calculate using the **GEOMEAN formula** is,

Select cell **B2**, enter the formula ** =GEOMEAN(A2:A6),** and press the “

**Enter**” key.

The result is “**24%**”, as shown above.

#### Example #2

We will calculate the average using the **GEOMEAN function** for the data in decimal.

In the table, the data is,

- Column A contains the Numbers.
- Column B displays the calculated Output.

The procedure to calculate using the **GEOMEAN formula** is,

Select cell **B2**, enter the formula ** =GEOMEAN(A2:A5),** and press the “

**Enter**” key.

The result is “**2.4347**”, as shown above.

#### Example #3

We will calculate the error using the **GEOMEAN function** for the data.

In the table, the data is,

- Column A contains the Data.
- Column B displays the calculated Output.

The procedure to calculate using the **GEOMEAN formula** is,

Enter the formula ** =GEOMEAN(A2:A3) **in cell

**B2**

*,***in cell**

*=GEOMEAN(“abc”)***B3**, and press the “

**Enter**” key after entering each formula

The results are a **“#NUM!”** error in cell **B2**, and a **“#VALUE!”** error in cell **B3**, as shown above. Column C is for our reference.

### Important Things To Note

- The “#NUM!” error occurs when,
- The provided values are less than or equal to zero.
- One or more cell values are negative numbers.

- The “#VALUE!” error occurs when,
- The supplied value is non-numeric.
- One or more cell values are an error or contain an error value.
