What is a measure in Power BI conceptually?

< 1 min read

A measure in Power BI is a dynamic calculation created using DAX that is evaluated based on filter context.
It does not store data physically; it calculates results at query time.
For example, Total Sales = SUM(Sales[Amount]) changes based on filters like date or region.
In one project, I created measures like Revenue, Profit %, and YTD Sales.
These automatically updated when users selected slicers in the report.
Measures are mainly used for aggregations and KPIs.
They help keep calculations centralized in the model instead of repeating logic in visuals.
