You can use the following simple formula to calculate the sum of values by group in an Excel spreadsheet:

=SUMIF(group_range, "group name", sum_range)

The following example shows how to use this formula in practice.

**Example: Sum by Group in Excel**

Suppose we have the following dataset that shows the total points scored by 15 different basketball players:

Now suppose we’d like to find the sum of the points scored, grouped by team.

To do so, we can use the **=UNIQUE()** function to first create a list of the unique teams. We’ll type the following formula into cell F2:

=UNIQUE(B2:B16)

Once we press enter, a list of unique team names will be displayed:

Next, we can use the **=SUMIF()** function to find the sum of points scored by players on each team.

We’ll type in the following formula into cell G2:

**=SUMIF(B2:B16, F2, C2:C16)**

We’ll then copy and paste this formula into the remaining cells in column G:

That’s it!

Column F displays each of the unique teams and column G displays the sum of the points scored by each team.
