How to Create Subtotals in Excel

Here’s what we’re going to achieve: We will group your Excel data and automatically calculate subtotals for each group. This will make it much easier to analyze large datasets and pull specific insights.

Step 1: Organize Your Data

First, make sure your data is structured in a table format with headers for each column.

Properly organized data is crucial for this feature to work. Ensure your table has no blank rows or columns, and each column has a header.

Step 2: Sort Your Data

Sort your data by the column you want to use for grouping.

To do this, select the column header, then go to the Data tab and click the Sort A to Z or Sort Z to A button. Sorting helps Excel know how to group the data.

Step 3: Select the Data

Highlight the entire range of data you want to subtotal.

Click and drag to select the data range or click inside the table and press Ctrl+A to select all.

Step 4: Open the Subtotal Dialog Box

Go to the Data tab and click on the Subtotal button.

This will open the Subtotal dialog box where you can set your grouping and summarizing preferences.

Step 5: Configure Subtotal Options

In the Subtotal dialog box, choose the column to group by, the function to use (like SUM), and the columns to subtotal.

For example, if you want to group by "Department" and sum the "Sales" column, set these options accordingly. Then click OK.

Once you’ve completed these steps, Excel will automatically insert rows displaying the subtotal for each group. It also adds a grand total at the bottom.
