# How to Sum Groups of Every N Values in a Row in Excel In this article, we will learn How to Sum Groups of Every N Values in a Row in Excel.

Scenario:

For Instance, you have a large list of data and you need to find the SUM of the numbers having a set of n values .

For this article we will be needing the use the following functions:

1. SUM Function
2. OFFSET function

Sum Groups of Every N Values formula in Excel

Now we will make a formula out of these functions. Here we will be given the data and we needed to find the SUM having a specified number of cells.

Formula

 = SUM ( OFFSET ( reference , ro , co , he , wi ) )

explained

• OFFSET function starts from the reference and traverse ro number of rows and co number of columns from the cell reference.
• Now the function starts picking groups of numbers having the number of values in the column and the number of values in the row.
• The OFFSET function now returns the array of numbers to the SUM function.
• SUM function adds up all the numbers and returns the SUM.

Example :

All of these might be confusing to understand. Let's understand how to use the function using an example. Here we have a data from A1 : D16. we need to find the SUM of Quantity & Total Price in a group of 5 with the given reference from the A1 cell. First we need to find the SUM of first 5 quantity which are values { 100 , 23 , 38 , 91 , 53 }

Use the Formula:

 = SUM ( OFFSET ( A1 , 1 , 2 , 5 , 1 ) )

Explanation:

• OFFSET function starts from the A1 cell and reaches the C2 cell traversing the 1 row and 2 columns.
• We need first 5 cells from C2 to C6 cell. So the height 5 and width will return us the numbers as shown below.

= SUM ( { 100 ; 23 ; 38 ; 91 ; 53 } )

• Now the SUM function returns the SUM of the values.

Here the A1 is given as cell reference & rest of the arguments are provided directly to the function. As you can see in the above snapshot the SUM of first five quantity comes out to be 305 .

Now we will get the SUM for all the other groups of 5 by changing the Row argument of the function

Use the Formula:

 = SUM ( OFFSET ( A1 , 6 , 2 , 5 , 1 ) ) As you can see the SUM of next five in the snapshot above. For the next five change the row argument to 11. Get the SUM of TotalPrice for the same by changing the Column argument to the function. As you can see from the above formula that you can get the SUM values by groups using the OFFSET function.

Here are all the observational notes using the formula in Excel
Notes :

1. The function returns #VALUE! error if the argument to the function is non-numeric.
2. The formula only works with numbers.
3. The argument array must be of the same length else the function.
