How to sum before average in a Pivot Table

When working with Pivot Tables in Excel, you may come across a situation where you need to sum a set of values before calculating the average. This can be a bit tricky, especially for entry-level users. In this article, we will guide you through the process of summing before averaging in a Pivot Table.

Step 1: Create a Pivot Table

The first step is to create a Pivot Table using your data. To do this, follow these steps:

1. Select the range of data that you want to analyze.
2. Go to the "Insert" tab in the Excel ribbon.
3. Click on the "PivotTable" button.
4. In the "Create PivotTable" dialog box, make sure the range is correct and choose where you want the Pivot Table to be placed.
5. Click "OK" to create the Pivot Table.

Step 2: Add Fields to the Pivot Table

Once you have created the Pivot Table, you need to add the fields that you want to analyze. To do this, follow these steps:

1. On the right side of the Excel window, you will see the "PivotTable Field List" pane.
2. Drag and drop the fields from your data into the "Rows" and "Values" areas of the PivotTable Field List.
3. In the "Values" area, you can choose the type of calculation you want to perform. In this case, we want to sum the values before averaging, so choose "Sum" for the desired field.

Step 3: Calculate the Average

Now that you have added the fields to the Pivot Table, you can calculate the average. To do this, follow these steps:

1. Right-click on the value field in the Pivot Table.
2. Select "Value Field Settings" from the context menu.
3. In the "Value Field Settings" dialog box, choose "Average" from the list of summary functions.
4. Click "OK" to apply the changes.

Step 4: Sum Before Average

By default, Excel calculates the average first and then sums the values. However, if you want to sum the values before averaging, you can use a calculated field. Here's how:

1. Right-click on any cell in the Pivot Table.
2. Select "Show Field List" from the context menu.
3. In the "PivotTable Field List" pane, click on the "Fields, Items & Sets" button.
4. Select "Calculated Field" from the dropdown menu.
5. In the "Insert Calculated Field" dialog box, enter a name for the calculated field (e.g., "SumBeforeAvg").
6. In the "Formula" field, enter the formula to sum the values before averaging. For example, if your original field is called "Amount," the formula would be =SUM(Amount)/COUNT(Amount).
7. Click "OK" to create the calculated field.

Now, you will see a new field in the Pivot Table that calculates the average after summing the values.

Summing before averaging in a Pivot Table can be a useful technique when analyzing data. By following the steps outlined in this article, you can easily perform this calculation and gain valuable insights from your data.
