# How to Sum by Group in Excel

Sometimes we may have the requirement that subtotal data by group in a table. To just subtotal data in a column, we can use **SUM** function directly; for data in a column, amount data in another column, we can use **SUMIF** function to subtotal data. But to subtotal data in group, we need to classify data by group firstly, then subtotal data which belongs to the same group. Above all, to subtotal data by group, we need to use formula based on **IF** function and **SUMIF** function. **IF** function is used for confirm ‘if value in a cell equals to its cell above’, if yes, then **SUMIF** function will be triggered and returns the corresponding total amount. This tutorial will help you to know the method with simple description, screenshots and explanation clearly. You can refer to below example for understanding well.

See example below:

You can see that fruits are classified to different groups, if you want to subtotal data by group, do you know the proper formula in this instance?

In C2, enter the formula **=IF(A2=A1,” “,SUMIF($A$2:$A$13,A2,$B$2:$B$13))**.

In this instance, we use **IF** function to return the subtotal value. We know that for **IF **function, **=IF(logical_test, [value if true], [value if false])**. In this formula, we use A2=A1 to classify data, if the two values are the same, nothing will be returned due to they belong to the same group, if they are different, that means a new group is detected, the **SUMIF** function will be used here.

And for **SUMIF** function **=SUMIF(range, criteria, [sum range])**, in this instance, we need to subtotal data by group,** $A$2:$A$3** is an absolute range for criteria, each data in column A is a criteria, **$B$2:$B$3** is an absolute range for matching values, so if we enter **SUM($A$2:$A$3,A2, $B$2:$B$3)** here, excel will search A2 value ‘**Apple**’ in **$A$2:$A$3**, and find all ‘**Apple**’ in this range, then subtotal all matching values in **$B$2:$B$3**, then return **SUMIF** value in C2 finally.

Click **Enter** to get returned value. We can see that 400 is correct.

Drag down the cell to copy formula. We can see that subtotal is recorded in the first row of each group. That’s because in this row, the data in column A is different with its cell above, a new group is found.

**Notes:**

1. In this instance, it is easy to locate the beginning data and ending data in a column, if there are multiple rows in the table and you are hard to find the ending data, you can use the full column as reference. Then formula will update to **=IF(A2=A1,” “,SUMIF(A:A,A2,B:B))**, it does work.

2. If you want to record subtotal in the last tow of each group, just enter the formula in the last row of the first group, and copy cell for the following cells.
