Module 04 · DAX basics
Your first measure
A calculation that responds to filters and context.
-
Step 1: Table tools → New measure, then type:
DAXTotal Revenue = SUM(Sales[Revenue]) -
Step 2: Drop the measure into a Card visual — it recalculates as you slice.
-
Step 3: Format the measure (currency, decimals) once in Measure tools — it sticks everywhere the measure is used.
Tip: Measures don’t use storage and are the heart of Power BI. Reach for them first.
