# Create a Calculated Column (Tutorial)

Looking for help with Power Pivot in Excel 2013? Go to Power Pivot Help on Office.com.

In this lesson you'll create new data in your PowerPivot workbook by adding calculated columns. A calculated column is based on data that already exists in your PowerPivot workbook.

You will create a calculated column named Total Profit based on the existing revenue and cost information in your data. In addition, you will also create calculated columns in the DimProducts table that reference product category values in other tables. Later, youâ€™ll use these related columns in a new hierarchy that includes product category, subcategory, and product names. As you will see, adding columns from related tables improves PivotTable exploration through hierarchies that include fields from other tables. For more information, see Calculated Columns.
