This article illustrates how to calculate the average age in excel. The average age of a group of people can be easily calculated by adding their age and then dividing the sum by the number of people in that group. But this can be very tedious to do manually for a large set of data. In that case, you should do that in excel instead. Here, you will learn 7 different ways to calculate the average age of a group of people in excel.

## 7 Ways to Calculate Average Age in Excel

Assume you have the following dataset. Then follow the methods below to calculate the average age of this group of people.

### 1. Calculate Average Age with Average Command

Follow the steps below to calculate the average age using the **Average** command in excel.

📌** Steps**

- First, select cell
**D14**. This cell should be the cell below the age column. If the data is in a row instead, this cell should be the adjacent cell to the right of the data row. - Then, select
**Home >> Editing >> AutoSum >> Average**as shown below.

- After that, a formula will be inserted automatically.

- Now press
**Enter**to get the desired result as follows.

- But, if there is a break in the data column i.e. an empty cell then the command won’t be able to detect the entire data.

### 2. Average Age with AVERAGE Function in Excel

Alternatively, you can use the **AVERAGE function** to get the same result. Apply the following formula in cell **D14** for that.

`=AVERAGE(D5:D12)`

### 3. Determine Average Age with Excel SUBTOTAL Function

The **SUBTOTAL function** also allows us to calculate the average age in excel. Enter the following formula in cell **D14** to do that.

`=SUBTOTAL(1,D5:D12)`

- This formula allows you to
**filter**your dataset. Here,**1**indicates the**AVERAGE function**.

- The earlier formula includes the hidden rows also. Enter the following formula instead to exclude the hidden rows.

`=SUBTOTAL(101,D5:D12)`

### 4. Get the Average Age with SUM & COUNT Functions

Alternatively, you can combine the **SUM** and the **COUNT** functions to get the same results. Enter the following formula in cell **D14** for that.

`=SUM(D5:D12)/COUNT(D5:D12)`

### 5. Calculate Average Based on Single Criteria

#### 5.1 Using AVERAGEIF Function

Now assume you want to calculate the average age of the people who are more than 25 years old. Then, apply the following formula with the **AVERAGEIF function** in cell **D14**.

`=AVERAGEIF(D5:D12,">25")`

#### 5.2 Combining SUMIF & COUNTIF Functions

Alternatively, you can get the same result by combining the **SUMIF** and the **COUNTIF** functions. Enter the following formula in cell **D14** to do that.

`=SUMIF(D5:D12,">25")/COUNTIF(D5:D12,">25")`

### 6. Calculate Average Age Based on Multiple Criteria

#### 6.1 Using AVERAGEIFS Function

Now assume you want to calculate the average age of the people who are married and more than 25 years old. Then enter the following formula with the **AVERAGEIFS function** to do that.

`=AVERAGEIFS(D5:D12,C5:C12,"=Married",D5:D12,">25")`

#### 6.2 Combining SUMIFS & COUNTIFS Functions

Alternatively, you can use the following formula with the **SUMIFS** and the **COUNTIFS** functions.

`=SUMIFS(D5:D12,C5:C12,"=Married",D5:D12,">25")/COUNTIFS(C5:C12,"=Married",D5:D12,">25")`

### 7. Calculate Average of Current Ages

Now imagine you have the birth dates instead of the ages of the people in **column D**. Then enter the following formula in cell **D14** (should be formatted as General) to calculate their average age. Here, the **TODAY function** returns the current date.

`=AVERAGE(TODAY()-D5:D12)/365`

## Things to Remember

- You may need to enter the
**Array Formulas**with**CTRL+SHIFT+ENTER**. - You can apply the above formulas to calculate the average of any group of numbers too.
