How to Create a Calculated Field in Excel
Creating a calculated field in Excel allows users to perform custom calculations in PivotTables, enabling more dynamic data analysis. This functionality is crucial for applying specific formulas that standard summary functions cannot accommodate.
Steps to Add a Calculated Field
Start by clicking on the PivotTable that needs the calculated field. Navigate to the 'Analyze' tab, then click on 'Fields, Items, & Sets'. Select 'Calculated Field'. In the dialog box that appears, type a name for your new field in the 'Name' box. Enter the desired formula in the 'Formula' box. Finally, click 'Add' to save and apply the calculated field.
Editing and Deleting Calculated Fields
To modify an existing calculated field, select the PivotTable and go to the 'Analyze' tab. Choose 'Fields, Items, & Sets', then 'Calculated Field'. Select the field you wish to edit from the list, change the formula in the 'Formula' box, and click 'Modify' to save the changes. To delete a calculated field, follow the same steps, but instead of modifying, select the field and click 'Delete'.
Use Cases and Examples
Calculated fields are versatile in various scenarios, such as calculating sales commissions that vary by region, or running totals of sales across different types. Examples include using a formula 0.15 * Sales for calculating a 15% commission on sales or summing up values for a grand total.
By following these guidelines, Excel users can efficiently use PivotTables to explore and analyze their data through custom calculations tailored to specific needs.
How to Create a Calculated Field in Excel
To effectively utilize data within pivot tables in Microsoft Excel, creating a calculated field can enhance your analytical capabilities. This guide provides a straightforward approach to adding calculated fields to your Excel pivot tables.
Initiate Calculated Field Creation
Select any cell within your pivot table. Navigate to the PivotTable Analyze tab on the Ribbon. Continue by selecting the Calculations group. Here, you will find the option Fields, Items, & Sets. By clicking it, you can access the Calculated Field command.
Configure and Save the Field
With the Calculated Field dialog box open, enter a distinctive name for your new field in the Name box. Formulate your calculation in the Formula box, ensuring not to reference worksheet cells directly. Utilize the SUM function to involve other pivot fields in your formula. Click Add to include this calculated field in your pivot table's data set.
Using and Modifying Your Calculated Field
Once added, your calculated field is integrated and available across any pivot tables sharing the same pivot cache. Should you need to adjust the formula of your calculated field, access the Analyze tab, click Fields, Items, & Sets, and select Calculated Field. From here, choose the field to modify, update the formula, and click Modify to save changes.
Finalizing and Maintenance
If the calculated field needs to be removed, follow the process of adjusting it, but instead click Delete in the dialog box. This action will remove the field from all related pivot tables. For ongoing management, these steps ensure that your calculated fields correctly reflect the data analysis you need. Keep your pivot table efficient by periodically reviewing and updating the calculations as necessary.
Incorporating calculated fields in Excel not only broadens the scope of your data analysis but also enhances the dynamic nature of your reports, enabling more sophisticated decision-making based on comprehensive data insights.

Examples of Creating Calculated Fields in Excel
Example 1: Calculating Total Sales
To calculate total sales, create a calculated field that multiplies the number of units sold by the price per unit. Suppose column A contains units sold, and column B holds prices, input the formula =A2*B2 in column C to compute the total for each row.
Example 2: Determining Average Scores
Average scores can be calculated by summing all individual scores and dividing by the count of scores. If scores are in column D from D2 to D10, use =AVERAGE(D2:D10) in another cell to find the average.
Example 3: Calculating Yearly Growth
To determine yearly growth, subtract the previous year's data from the current year's data, then divide by the previous year’s data. For year 1 in E2 and year 2 in F2, apply the formula =((F2-E2)/E2) to calculate growth percentage.
Example 4: Computing Loan Interest
For calculating interest on a loan using a constant interest rate, multiply the principal amount by the interest rate. If G2 is the principal and H2 the rate, use =G2*H2 to get the interest amount in a new column.
Example 5: Sum of Expenses
Summing total expenses from multiple categories can be efficiently managed using the SUM function. If columns J to N represent different expense categories from rows 2 to 5, insert =SUM(J2:N2) at the end of row 2 and drag down to row 5 to get total expenses for each record.
