# Excel Pivot Table Calculated Field

“Pivot Table calculated field” is an option to include more data or calculations in the pivot table. Often, we need to add our own custom calculations that can refer to other fields in the data set for our reports.

In the below examples we create a sales report by-product with an additional column “**Sales Differences**” [2020_Sales – 2019_Sales]. Calculated field “**Sales Differences**” calculation refers to other fields in the dataset [subtract 2019_Sales from 2020_Sales].

**Eg:** We have a data set in four columns “**Product**”, ”**Customer**”, “**2019_Sales**” and “**2020_Sales**” as below
