11 Steps to Create a Pivot Table that Subtracts Opposite Numbers

Pivot tables are a powerful tool in Excel that can be used to summarize and analyze data. One of the many things that pivot tables can do is subtract opposite numbers. This can be useful for tasks such as finding the difference between two sets of numbers, or for calculating the net income or loss for a business. When you create a pivot table, you can specify which fields you want to use as rows, columns, and values. In order for the pivot table to subtract opposite numbers, you must use a numeric field as the values field. For example, if you have a data set that includes sales figures for different products, you could create a pivot table that shows the total sales for each product. In the values field, you would select the sales figures field. Once you have created the pivot table, you can use the Summarize Values By option to specify how the values should be summarized.

The Summarize Values By option allows you to choose from a variety of summary functions, including sum, average, and count. If you want to subtract opposite numbers, you should select the sum function. Once you have selected the sum function, you can click on the OK button to create the pivot table. The pivot table will display the total sales for each product. If there are any negative sales figures, they will be subtracted from the total. For example, if one of the products had total sales of $100 and another product had total sales of -$50, the pivot table would display the net sales as $50. You can use the pivot table to analyze the data and identify trends and patterns. The pivot table can also be used to create charts and graphs that can help you visualize the data.

Pivot tables are a versatile tool that can be used for a variety of tasks. By understanding how to use the Summarize Values By option, you can use pivot tables to subtract opposite numbers and perform other calculations. This can be useful for a variety of tasks, such as analyzing financial data, calculating averages, and finding differences between two sets of numbers. With a little practice, you can use pivot tables to efficiently and effectively analyze your data.

Understanding Pivot Tables

Pivot tables are powerful tools in Microsoft Excel and Google Sheets that allow you to summarize and analyze data efficiently. They let you create interactive tables that can be reconfigured by dragging and dropping fields, providing a comprehensive view of your data from various perspectives.

At their core, pivot tables consist of four main components: rows, columns, values, and filters. Rows and columns represent the categories or groups of data you want to analyze, while values provide the numerical data associated with those groups. Filters allow you to narrow down the data to specific subsets, focusing on the aspects that are most relevant to your analysis.

Pivot tables offer a versatile platform for data manipulation and exploration. They enable you to perform calculations, such as sums, averages, and counts, on the data and create clear, concise reports that highlight the key insights and patterns within your dataset.

Subtracting Numbers

Subtracting numbers in a pivot table is a straightforward process that allows you to compare different values and identify deltas or differences. To subtract numbers in a pivot table, follow these steps:

Click on the cell where you want to display the subtraction result.
Go to the “Formula Bar” at the top of the window.
Enter a formula that subtracts the values of two cells. For example, to subtract the value in cell A2 from the value in cell B2, enter the formula “=B2-A2”.
Press “Enter” and the result will be displayed in the cell.

You can also use the “Calculated Field” feature in pivot tables to create a new field that represents the difference between two values. This allows you to save the resulting calculation and reuse it in other parts of the pivot table or in other calculations.

Step 1: Set Up the Pivot Table Source Data

2. Specify the Data Range

Precisely selecting the data range is crucial for an accurate pivot table. To do this, ensure you highlight all the pertinent cells within your dataset. Avoid leaving out any necessary columns or rows, as this could result in incorrect data or missing values in the generated pivot table. For clarity, it’s recommended to use named ranges or specific cell references within the data source when defining the data range.

When defining the data range, meticulous attention should be paid to the inclusion of header rows and columns. If your dataset contains headers, make sure they are included within the selected range. However, if the headers are not present, ensure they are excluded to avoid potential errors in the pivot table creation process.

Consider the following table as an example:

Month	Sales	Returns
January	$10,000	$1,000
February	$12,000	$800
March	$15,000	$900

To define the data range for this example, you would highlight cells A1:C4, ensuring that both the header row and the data rows are included in the selection.

Step 2: Insert the Pivot Table

Set Up the Pivot Table

Now, let’s create the pivot table itself. Follow these steps:

Select the Data: Highlight the range of cells containing the data you want to analyze.
Insert the Pivot Table: Go to the "Insert" tab and click on "PivotTable."
Choose the Destination: A pop-up window will appear. Select the location where you want the pivot table to be placed. You can choose an existing worksheet or create a new one.

Add Fields to the Pivot Table

Once the pivot table is inserted, you need to add fields to it for further analysis. Here’s how:

Drag and Drop Fields: From the "PivotTable Fields" pane on the right, drag fields into the "Rows," "Columns," or "Values" areas of the pivot table.
Choose Fields: Select the fields that are relevant to your analysis. For example, drag the "Category" field to "Rows" and the "Amount" field to "Values."

Configure Pivot Table Settings

After adding fields, you can adjust various settings in the pivot table to customize its appearance and behavior:

Field Settings: Right-click on a field in the "Rows," "Columns," or "Values" area to access field settings. You can change the sort order, grouping, and other options.
PivotTable Options: Click on the "PivotTable Options" button in the "PivotTable Analyze" tab to control various settings, such as show gridlines, enable drill-down, and apply filters.

Step 3: Place Fields in the Pivot Table

Drag Value Field to “Values” Area

To show the differences between numbers, you need to add the field that contains the numerical values to the “Values” area of the Pivot Table. This area is typically located at the bottom right corner of the Pivot Table. Simply drag and drop the value field into the “Values” area.

Drag Row Label Field to “Rows” Area

The Row Labels area determines the rows in your Pivot Table. Drag and drop the field that you want to use as row labels into the “Rows” area. This field typically provides a specific category or group for each row.

Drag Column Label Field to “Columns” Area

Similar to the Row Labels, the Column Labels area determines the columns in your Pivot Table. Drag and drop the field that you want to use as column labels into the “Columns” area. This field typically represents a different category or group for each column.

Configure Value Field Settings

Once you have placed the fields, right-click on the value field in the “Values” area. In the context menu, select “Value Field Settings”. This will open a dialog box where you can configure how the values are displayed.

In the “Summarize value field by” drop-down list, select “Subtract” to display the differences between the numbers.

Additional Tips

You can drag multiple fields into the “Rows” or “Columns” areas to create a more detailed Pivot Table.
You can use the “Sort & Filter” options in the Pivot Table toolbar to customize the order and filtering of the data.
You can also use Slicers, which are interactive filters, to dynamically filter the data in the Pivot Table.

Step 4: Create Calculated Field for Subtraction

5. Define the Calculation

Now, let’s define the calculation to subtract the opposite numbers. Click on the “Insert” tab in the PivotTable Tools section, then select “Calculated Field”. In the “Name” field, enter a descriptive name for your calculated field, such as “Subtracted Values.”

In the “Formula” field, use the following syntax:

“`
=FieldName1 – FieldName2
“`

Replace “FieldName1” with the name of the field containing the positive numbers and “FieldName2” with the name of the field containing the negative numbers. In our example, the positive numbers are in the “Sales” field and the negative numbers are in the “Returns” field, so the formula would be:

“`
=Sales – Returns
“`

Once you’ve entered the formula, click “OK” to add the calculated field to your pivot table. The calculated field will now be displayed in the “Fields” list and can be added to the Rows, Columns, or Values sections of the pivot table.

Example:

Let’s say you have the following data table:

Month	Sales	Returns
January	$100,000	$10,000
February	$120,000	$12,000
March	$140,000	$14,000

After creating a calculated field using the “Sales – Returns” formula, the pivot table would show the following values:

Month	Sales	Returns	Subtracted Values
January	$100,000	$10,000	$90,000
February	$120,000	$12,000	$108,000
March	$140,000	$14,000	$126,000

Step 5: Subtract Corresponding Values

To subtract corresponding values in a pivot table, you will need to use the CALCULATE function. The CALCULATE function allows you to perform calculations on data in a pivot table, and it can be used to subtract values from different rows or columns.

To use the CALCULATE function to subtract corresponding values, you will need to specify the following arguments:

1. Expression: The expression that you want to calculate. In this case, you will want to specify the difference between two values.
2. Filter1: The filter that you want to apply to the first value.
3. Filter2: The filter that you want to apply to the second value.

For example, the following formula would subtract the value in the “Sales” column for the “East” region from the value in the “Sales” column for the “West” region:

“`
=CALCULATE([Sales], [Region] = “East”) – CALCULATE([Sales], [Region] = “West”)
“`

You can also use the CALCULATE function to subtract corresponding values from different rows. For example, the following formula would subtract the value in the “Sales” column for the first row from the value in the “Sales” column for the second row:

“`
=CALCULATE([Sales], ROW() = 1) – CALCULATE([Sales], ROW() = 2)
“`

The CALCULATE function is a powerful tool that can be used to perform a variety of calculations on data in a pivot table. By understanding how to use the CALCULATE function, you can create pivot tables that provide you with the information you need to make informed decisions.

Subtracting Corresponding Values from Different Tables

In some cases, you may want to subtract corresponding values from different tables. For example, you may want to subtract the sales from one table from the sales from another table. To do this, you will need to use the RELATED function. The RELATED function allows you to retrieve data from a related table.

To use the RELATED function to subtract corresponding values from different tables, you will need to specify the following arguments:

1. Expression: The expression that you want to calculate. In this case, you will want to specify the difference between two values.
2. Table: The table that you want to retrieve data from.
3. Filter: The filter that you want to apply to the data.

For example, the following formula would subtract the value in the “Sales” column from the “Sales” table from the value in the “Sales” column from the “Orders” table:

“`
=CALCULATE([Sales], RELATED([Sales Table])) – CALCULATE([Sales], RELATED([Orders Table]))
“`

The RELATED function is a powerful tool that can be used to perform a variety of calculations on data from different tables. By understanding how to use the RELATED function, you can create pivot tables that provide you with the information you need to make informed decisions.

Step 6: Adjust Pivot Table Formatting

Cell Formatting

Customize the appearance of cells by selecting them and applying formatting options from the “Home” tab. You can change font, size, color, and background color. For negative numbers, right-click on the selected cells, select “Format Cells”, and set the “Number” format to a custom format with negative numbers displayed in a different color or brackets.

Column Width and Row Height

Adjust the width of columns and the height of rows to make the table easier to read. Select a column or row header and drag its border to the desired size. You can also double-click on the border to automatically fit the content.

Hide or Show Grand Totals

Grand totals can be hidden or shown as needed. Right-click on the grand total cell and select “Hide Grand Total” or “Show Grand Total”.

Add Calculated Fields

Calculated fields allow you to perform calculations on the data in the pivot table. Select the “Analyze” tab and click on “Calculated Field”. Enter a name and formula for the calculated field, such as “(Value1) – (Value2)” to subtract two values.

Freeze Panes

Freeze panes to keep certain rows or columns in place while scrolling. Select the rows or columns you want to freeze and go to the “View” tab. Click on “Freeze Panes” and select the desired option, such as “Freeze Top Row” or “Freeze First Column”.

Create a Calculated Field to Subtract Opposite Numbers

To create a calculated field that subtracts opposite numbers, follow these steps:

Select the “Analyze” tab and click on “Calculated Field”.
Enter a name for the field, such as “Difference”.
In the formula field, enter the formula “IF([Value] < 0, [Value] * -1, [Value])”.
Click “OK” to create the calculated field.

Value	Difference
10	10
-5	5
0	0

Step 7: Use Filters and Slicers for Refinement

To further refine your pivot table, you can apply filters and slicers to specific data fields, allowing you to focus on relevant subsets of information. For instance:

8. Utilize Slicers for Interactive Filtering

Slicers provide an interactive way to filter your data. By clicking on specific values in a slicer, you can instantly filter the pivot table to display only the data that meets the selected criteria. This allows you to quickly isolate specific trends or patterns in your data.

To add a slicer, select the field you want to filter by from the PivotTable Fields list. Drag it to the Slicer section of the Field List. Multiple slicers can be added, enabling you to filter by multiple criteria simultaneously.

Here’s an example of using a slicer to filter a pivot table that summarizes sales data by region and product:

Region	Sales
Central	$10,000
East	$12,000
West	$15,000

By clicking on the “Central” value in the Region slicer, you can isolate the sales data for the Central region:

Product	Sales
A	$3,000
B	$4,000
C	$3,000

Step 8: Customize Pivot Table Design

Once you have created your pivot table, you can customize its design to make it more visually appealing and easier to read. To do this, select the pivot table and click on the “Design” tab in the ribbon. Here you can change the font, color, and size of the text, as well as the borders and shading of the cells.

Customizing Number Formats

One important aspect of customizing your pivot table is to format the numbers correctly. By default, pivot tables will display numbers in a general format, but you can change this to a more specific format, such as currency, percentage, or date.

To change the number format, select the column or cell that you want to format and click on the “Number Format” drop-down menu in the “Number” group on the “Home” tab. Here you can choose from a variety of pre-defined formats, or you can create your own custom format.

Pre-defined Formats	Description
Currency	Displays numbers as currency, with a currency symbol and thousands separator.
Percentage	Displays numbers as percentages, with a percent sign.
Date	Displays numbers as dates, with a date format that you specify.
Custom	Allows you to create your own custom number format, using a variety of placeholders and symbols.

By customizing the number formats in your pivot table, you can make it easier to read and interpret the data.

Best Practices for Pivot Table Subtraction

10. Handle Negative Values Carefully

Pivot tables automatically subtract positive and negative values, but negative values can sometimes lead to misleading results. To prevent this, follow these best practices:

Use absolute values. Convert negative values to their absolute values (e.g., -5 to 5) before performing subtraction to ensure that the result is always positive.
Use the SUMIFS function. The SUMIFS function allows you to specify multiple criteria, including whether a value is positive or negative. This enables you to exclude negative values from the calculation.
Create a separate field for negative values. If you need to display both positive and negative values in your pivot table, create a separate field for negative values and use the SUM function to calculate the sum.

Method	Pros	Cons
Absolute values	Ensures positive results	Can distort the underlying data
SUMIFS function	Allows for precise filtering	Can be complex to implement
Separate field for negative values	Preserves the original data	Requires additional setup
