Get FREE Advanced Excel Exercises with Solutions!

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 formula 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. Read More: How to Average a Column in Excel

### 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. ## Conclusion
