Microsoft Power BI allows you to create custom or calculated columns from existing ones. In this section, we show you how to create calculated columns with examples.
To demonstrate these calculated columns, we will use the SQL Data Source that we created in Connect to SQL Server article. So, refer to the same.
How to Create Calculated Columns in Power BI
In order to create it, please click on the New Column option under the Modeling tab.
Clicking the New tab opens the Power BI DAX formula bar, as shown below.
You can rename this as per your requirement. Let me rename the column as Profit.
For this Calculated Columns demo purpose, we select Sales Amount and Total Product Cost from the Fact Internet Sales table. As you can see from the screenshot below, Power BI IntelliSense is showing the suggestions while I was typing.
From the screenshot below, you can see that we are calculating the Profit by removing the Total Product Cost from Sales Amount. Next, a new col called profit is created by clicking the enter.
Let me add the calculated col we created earlier to the table. Remember, this is the table that we designed in the Table Report article.
