Sometimes, while working in Excel, users need to average cell values for working purposes. While working in a big data set, doing the average of cells one by one is a tiresome and tedious process. The process will become much easier if users can average every nth row by just using one formula or command. In this article, I will show you how to average every nth row in Excel.

## How to Average Every Nth Row in Excel: 3 Ways

In this article, you will see three different ways to average every nth row in Excel. First of all, I will combine some Excel functions to calculate the average. Then, in the second approach, I will merge some functions of Excel for the same purpose. Lastly, I will use a VBA code to calculate the average of a particular row range.

To explain my article further, I will use the following sample data set. Here, I have the random data for sales for the twenty-five days of a company.

### 1. Combining Functions to Average Every Nth Row

In the first method, I will combine some Excel functions to average every nth row in Excel. In order to do that, I will combine the **ROW**, **OFFSET***,* and **AVERAGE** functions of Excel. I will explain the role of each of these functions in the calculation of this discussion. See the below-given steps to learn more about this procedure.

**Steps:**

- First of all, I will calculate the average of the data in the
*Sales*column for every three rows. - In order to do that, write the following formula in cell
**D5**.

`=AVERAGE(OFFSET($C$5,(ROW()-ROW($D$5))*3,,3,))`

**Formula Breakdown**

**OFFSET($C$5,(ROW()-ROW($D$5))*3,,3,)**: The**OFFSET**function with the help of the**ROW**function will fetch the data starting from cell**C5**for calculation. Here, the row height is 3 so this function will collect three rows of height downward starting from cell**C5**.**AVERAGE(OFFSET($C$5,(ROW()-ROW($D$5))*5,,5,))**: Finally, the**AVERAGE**function will calculate the average of the values, found from the previous steps.

- Next, press
**Enter**to see the average of the first three rows in cell**D5**. - Then, use AutoFill to drag the formulaÂ to the lower cells of this column.
- Here, you will see a numerical value, till the formula finds values for calculations.
- After a certain period, it will show
*#DIV/0!*as an error.

- Now, modify the formula a little bit and you will see the average for every five rows.

### 2. Merging Functions to Average Every Nth Row

In my second approach, I will merge different functions of Excel to find the average. In this merge, I will use the combination of **AVERAGE**, **INDEX ,** and

**ROW**functions of Excel.

**Steps:**

- Firstly, I will determine the average sales for every three rows.
- To do that, in cell
**D5**, use the following merging formula.

`=AVERAGE(INDEX(C:C,5+3*(ROW()-ROW($D$5))):INDEX(C:C,4+3*(ROW()-ROW($D$5)+1)))`

**Formula Breakdown**

**INDEX(C:C,5+3*(ROW()-ROW($D$5)))**: The**INDEX**function will find the value from the cell range or column**C**that falls in row**5**. The row number is calculated using the**ROW**function.**INDEX(C:C,4+3*(ROW()-ROW($D$5)+1))**: Similarly, the**INDEX**function will find the value from the third row of the data set, which is row**9**in the worksheet.**AVERAGE(INDEX(C:C,5+3*(ROW()-ROW($D$5))):****INDEX(C:C,4+3*(ROW()-ROW($D$5)+1)))**: Finally, the**AVERAGE**function will calculate the average of these two-row ranges found in the previous two sections.

- Press
**Enter**to find out the average of the first three rows. - Then, drag the same formula to the lower cells of the column by using the
**Fill Handle**. - Consequently, the formula will show numerical values based on the size of your data set.
- After a certain period, it will show
*#DIV/0!*as an error.

- Furthermore, to get the average for every five rows with the same formula, you have to modify the formula a little bit.

### 3. Applying VBA to Average Nth Row in Excel

As the last procedure of this task, I will apply a** VBA** code. By giving proper sequence and command into the code, I will determine the average of a fixed cell range.

**Steps:**

- First of all, go to the
**Developer**tab of the ribbon. - From the
**Code**group, select**Visual Basic**.

- Next, the
**Visual Basic**window will appear after the previous step. - Then, from the
**Insert**tab choose**Module**.

- Copy the following code into the module.
- Here, I have entered
**C5:C7**as the range to calculate the average that represents the first three rows of the data set.

```
Sub Average_Row_Range()
Dim x As Integer
'Assign the row range for calculating average
x = WorksheetFunction.Average(Range("C5:C9"))
'Displaying the result in a msgbox
MsgBox "The average of this row range is " & x
End Sub
```

**VBA Breakdown**

- Firstly, naming the sub-procedure.

`Sub Average_Row_Range()`

- Then, declare the variables.

`Dim x As Integer`

- Assign the desired drow range for calculating the average.

`x = WorksheetFunction.Average(Range("C5:C9"))`

- Finally, use a message box to display the result.

`MsgBox "The average of this row range is " & x`

- Save the code, and then after keeping the cursor in the module press
**F5**or the**Run**button to run the code.

- Finally, you will see the average of the row range as a result after running the code.

- Consequently, change the cell range in the code, and you will see the average for the first five rows in the message box.

## Sum Every Nth Row in Excel

After discussing how to average every nth row in Excel, we will now see a simple procedure to sum every nth row in Excel. To do this, we will have to use three Excel functions that are- **SUM**, **MOD**, and **ROW** functions.

**Steps:**

- Firstly, I will show the row numbers that will be summed up by those Excel functions.
- In order to do that, insert the following formula into cell
**D5**.

`=MOD(ROW(C5)-4,5)=0`

- I want to sum every third row from the data set, by using the above formula. You can see which row will be added to the main formula.

- Enter the following formula in cell
**E5**, to sum up every third row and show the result.

`=SUM(C5:C29*(MOD(ROW(C5:C29)-1,3)=0))`

**Formula Breakdown**

**MOD(ROW(C5:C29)-1,3)=0**: The**MOD**function will return 0 for every third row in the range**C5:C29**. As the data set does not start from cell**A1**, to find out the correct value of the row for this cell range, -1 has been used in the formula.**SUM(C5:C29*(MOD(ROW(C5:C29)-1,3)=0))**: Finally, the**SUM**function will sum up values from the rows that are true for the**MOD**function.

- Press
**Enter**and see the desired result in cell**E5**.

- Moreover, by modifying the above formula, you can determine the sum of every five rows from the data set.
