Adding a Calculated Field in Power BI
Power BI allows users to create calculated fields, which are new columns created based on formulas or expressions created by the user. These calculated fields can be used to perform various calculations or create custom aggregations in your Power BI reports. Here’s how you can add a calculated field in Power BI:
- Open your Power BI Desktop application.
- Load your data source into Power BI by going to Home tab and clicking on Get Data button.
- Select your data source from the available options and follow the prompts to connect and load your data into Power BI.
- Once your data is loaded, navigate to the Data tab in the Power BI Desktop application.
- In the Fields pane on the right-hand side, locate the table or source that you want to add the calculated field to.
- Right-click on the table or source and select New Column from the context menu.
- In the formula bar that appears at the top, enter your desired formula or expression for the calculated field.
- For example, let’s say you want to create a calculated field called “Total Sales” that sums up the “Sales” column and multiplies it by a factor of 1.1. You can enter the following formula in the formula bar:
Total Sales = SUM('Table'[Sales]) * 1.1 - Press Enter to apply the formula and create the calculated field.
- The calculated field will now be added as a new column in the table or source.
- You can use the calculated field in visualizations, measures, or any other calculations within your Power BI report.
That’s it! You have successfully added a calculated field in Power BI. Remember, calculated fields can be powerful tools to create custom calculations and aggregations based on your data, allowing for more flexibility and insights in your reports.
