What is an Excel 2013 Calculated Field?

In Excel 2013, a calculated field is a custom formula that you can add to a PivotTable to perform calculations using the values from other fields in that PivotTable. It allows you to create new, virtual columns of data without altering your original source data. For example, if your data contains ‘Units Sold’ and ‘Price per Unit’, you can create a calculated field to compute ‘Total Revenue’ by multiplying these two fields. This is a powerful feature for data analysis, enabling on-the-fly calculations directly within your summary report.

This functionality is essential for business analysts, financial planners, and anyone who uses PivotTables to summarize and analyze data, as it provides flexibility to extend the analysis beyond the raw data available.

The Formula for Calculated Fields

The syntax for a calculated field formula in Excel 2013 always begins with an equals sign (=). The formula uses the names of existing PivotTable fields as variables. If a field name contains spaces or special characters, it must be enclosed in single quotes.

For example, to create a field named ‘Sales Tax’ by calculating 7.5% of a ‘Total Sales’ field, the formula would be:

='Total Sales' * 0.075

Formula Variables & Operators

Component	Meaning	Unit	Example
Field Name	A reference to an existing data field in the PivotTable.	Varies (e.g., Currency, Count, Percentage)	‘Units Sold’, ‘Revenue’
Operator	Standard mathematical operators for calculations.	Unitless	+, -, *, /
Constant	A fixed number used in the calculation.	Unitless	1.15 (for a 15% markup)

Practical Examples of Calculated Fields

Example 1: Calculating Total Revenue

Imagine your source data has columns for ‘Quantity’ and ‘Unit Price’. You can create a calculated field to find the total revenue for each item in your PivotTable.

• Inputs: A ‘Quantity’ field and a ‘Unit Price’ field.
• Formula: ='Quantity' * 'Unit Price'
• Result: A new ‘Total Revenue’ field appears in your PivotTable, showing the calculated revenue for each row item.

Example 2: Calculating Profit Margin Percentage

If your data includes ‘Profit’ and ‘Revenue’, you can calculate the profit margin without adding a new column to your source data.

• Inputs: A ‘Profit’ field and a ‘Revenue’ field.
• Formula: ='Profit' / 'Revenue'
• Result: A new field showing the profit margin as a decimal. You can then format this field as a percentage in the PivotTable’s Value Field Settings. For more advanced formulas, see our guide on .

How to Use This Calculated Field Simulator

This interactive tool helps you understand the mechanics of excel 2013 using formulas in calculated fields:

1. Review the Source Data: Examine the static “Source Data: Regional Sales” table to understand the available fields: ‘Region’, ‘Product’, ‘Units Sold’, and ‘Unit Cost’.
2. Enter a Formula: In the “Calculated Field Formula” input box, type a formula. A default formula (='Units Sold' * 'Unit Cost') is provided. You can try others, like ='Units Sold' * 1.1 to simulate a 10% increase in units.
3. Apply the Formula: Click the “Apply Formula” button. The tool will process your formula against each row of the source data.
4. Interpret the Results:
   • The “Resulting PivotTable View” will update, showing the original fields plus a new column with your calculated results.
   • The “Total of Calculated Field” shows the sum of your new virtual column, similar to a PivotTable’s Grand Total.
   • The bar chart provides a visual comparison of the calculated values, grouped by product.

Key Factors That Affect Calculated Fields

Understanding these factors is crucial for accurate analysis when using formulas in calculated fields.

• Order of Operations: Excel follows standard mathematical order (PEMDAS/BODMAS). Use parentheses to control the calculation sequence.
• Summarization of Fields: A calculated field formula operates on the SUM of the fields it references, not on the individual rows. For instance, ='Field A' + 'Field B' adds the SUM of Field A to the SUM of Field B. It does not sum the row-by-row additions. This is a common point of confusion.
• Data Types: Ensure you are performing calculations on numeric fields. Applying mathematical operators to text fields will result in a #VALUE! error. Our guide to can help prevent such issues.
• Using Constants: You can include fixed numbers (constants) in your formulas, such as for calculating taxes (e.g., ='Sales' * 1.05) or commission rates.
• Calculated Items vs. Calculated Fields: A calculated field adds a new “column” to the PivotTable. A calculated item, by contrast, adds a new “row” within a field by calculating based on other items in the same field.
• Source Data Integrity: The accuracy of your calculated field depends entirely on the accuracy of the underlying source data.

Frequently Asked Questions (FAQ)

1. What’s the difference between a calculated field and a calculated item?

A calculated field is a new field (like a column) that performs calculations on other fields. A calculated item is a new item within an existing field (like a row) that performs calculations on other items within that same field.

2. Can I use complex Excel functions like IF or VLOOKUP in a calculated field?

You can use simple functions that don’t require cell references or array functions. IF statements are usable, but functions like VLOOKUP that need specific cell ranges are not supported.

3. Why is my calculated field total incorrect?

This usually happens because calculated fields operate on the sum of the underlying data, not the individual records. The Grand Total line applies the same formula to the sum of the inputs, which can yield a different result than summing the individual calculated results.

4. How do I edit or delete a calculated field in Excel 2013?

To edit or delete, select the PivotTable, go to the Analyze tab, click ‘Fields, Items, & Sets’, and choose ‘Calculated Field’. In the dialog box, you can select the field from the dropdown to modify or delete it.

5. Do calculated fields update automatically if my source data changes?

Yes, but you must first refresh the PivotTable. After changing the source data, right-click the PivotTable and select “Refresh”. The calculated field will then update based on the new data.

6. Can I use a calculated field in a slicer or filter?

No, calculated fields cannot be used in slicers or report filters. They are designed to be value fields within the PivotTable itself.

7. What does the #VALUE! error mean in my calculated field?

This error typically occurs when your formula attempts to perform a mathematical operation on non-numeric (text) data or if the formula syntax is invalid.

8. Can I use field names with spaces in my formula?

Yes, but you must enclose the field name in single quotes (e.g., =’Unit Price’ * ‘Units Sold’). If you don’t use quotes, Excel will return an error.
