Here we can see, “How to Add a Calculated Column in Power Bi”
When it comes to computations, Power BI is a very helpful tool. However, many users of Power BI are having trouble adding a calculated column.
On the official forum, a user-provided the following description of the issue:
I’m quite new with Power Bi and i am using a matrix to group my data like this (image below). Now I want to add a new column which allow me to make a new calculation = ([q’ty per unit of 3rd month] – [q’ty per unit of 2nd month]) * [Price per Unit of 3rd month]
Is there any simple way help me to do so since I’m not an expect with DAX. Thanks for your help.
The OP wishes to add a new column to enable a new calculation. Today, we’ll walk you through the process step-by-step.
Steps to add a calculated column in Power BI
1. Create a measure using DAX
The mathematical language of Power BI is called DAX, which stands for Data Analysis Expression. As seen in the image below, you can add formulas and functions for your columns here.
Add the following to the upper case (second arrow):
Result = VAR qty_per_unit_of_3rd_month = CALCULATE ( MAX ( Table[q’ty per unit] ), FILTER ( Table, Table[Month] = 3 ) ) VAR qty_per_unit_of_2rd_month = CALCULATE ( MAX ( Table[q’ty per unit] ), FILTER ( Table, Table[Month] = 2 ) ) VAR Price_per_Unit_of_3rd_month = CALCULATE ( MAX ( Table[Price per Unit] ), FILTER ( Table, Table[Month] = 3 ) ) RETURN qty_per_unit_of_3rd_month – qty_per_unit_of_2rd_month * Price_per_Unit_of_3rd_month
To make the formulas applicable to your situation, modify the values.
2. Apply the measure directly to the slicer
Additionally, you can change the action as follows:
Result = VAR qty_per_unit_of_first_month_in_slicer = CALCULATE ( MIN ( Table[q’ty per unit] ), ALLSELECTED ( Table ) ) VAR qty_per_unit_of_last_month_in_slicer = CALCULATE ( MAX ( Table[q’ty per unit] ), ALLSELECTED ( Table ) ) VAR Price_per_Unit_of_last_month = CALCULATE ( MAX ( Table[Price per Unit] ), FILTER ( Table, Table[Month] = qty_per_unit_of_last_month_in_slicer ) ) RETURN qty_per_unit_of_last_month_in_slicer – qty_per_unit_of_first_month_in_slicer * Price_per_Unit_of_last_month
You can compare several months, such as the first and last, using the second measure because it directly affects the slicer.

User Questions
1. In power bi, how do I add a calculated column?
Click the drop-down menu next to ProductSubcategory in the Fields pane and choose the New column. A newly calculated column is given the name Column by default. The Formula bar, which is available for you to name your column and write a DAX formula, displays along the top of the Report canvas when you choose the New column.
2. Is it possible to construct calculated columns in the power BI service?
Power View, the experience for creating and consuming reports, and dashboards are the only components of Power BI Service. Only Power BI Desktop offers the Power Pivot/data modelling component. This covers full DAX features, such as adding measurements, calculated columns, and relationship definitions.
3. What distinguishes a measure from a calculated column?
The context of the judgement makes a difference. A calculated column is computed at the row level within the table it belongs to. In contrast, a measure is evaluated in the context of the cell evaluated in a report or in a DAX query.
