In Microsoft Power BI, you can create a custom calculated measure (or numeric aggregated calculation) from existing columns. This article shows you how to create calculated measures with an example.
To demonstrate these Power BI calculated measures, we will use the Data Source we created in Connect to SQL Server article.
How to Create Calculated Measures in Power BI
In order to create it, please click on the New Measure option under the Modeling tab.
Clicking the Power BI New tab opens the DAX formula bar with the default measures name, as shown below.
You can rename this as per your requirement. Let me rename this one as Total Sale.
For the Power BI calculated measures demo purpose, we add the Internet Sales Amount, Reseller Sales Amount from Fact Internet Sales, and Fact Reseller Sales tables. Unlike calculated columns, you have to use the aggregated function to create it.
As you can see from the screenshot below, Power BI IntelliSense was showing the suggestions while I was typing.
By clicking enter or any key, a new Measure called TotalSale will create.
Let me add the calculated Measure that we created earlier to a Power BI Table. Please refer Table Report article to understand the steps involved in creating a table.
Let me minimize the Fields tab and Visualization so you can focus on table values.
You can also apply filters on these too. From the screenshot below, you can see that we selected a few areas in our Pie Chart, and the same has also been reflected in the table.
