Often you may want to sum the values of some dataset in Excel based on a category or group.

For example, suppose we have the following dataset and we’d like to sum the total “points” by team:

The following step-by-step example shows how to do so.

**Step 1: Enter the Data**

First, enter the data values into Excel:

**Step 2: Find the Unique Categories**

Next, we need to use the **=UNIQUE()** function to produce a list of unique values in a certain range.

In our example, we’ll type the following formula in cell **E2**:

=UNIQUE(B2:B12)

This will produce a list of unique teams:

**Step 3: Find the Sum by Category**

Next, we will use the **SUMIF(range, criterion, sum_range)** function to find the sum of the points scored by each team.

In our example, we’ll type the following formula in cell **F3**:

=SUMIF($B$2:$C$12, E3, $C$2:$C$12)

This will calculate the sum of points scored by each team:

This tells us:

- The total points scored by players on the Lakers is
**21.6**. - The total points scored by players on the Mavericks is
**56.4**. - The total points scored by players on the Spurs is
**48.8**. - The total points scored by players on the Warriors is
**65**.
