1/ Curious about the power duo of #PowerBI - Measures and Calculated Columns? Let's break down when to use each and why they're essential in your data analysis toolkit! 📊🧵

2/ 𝐌𝐞𝐚𝐬𝐮𝐫𝐞𝐬: These dynamic calculations evaluate based on the context of the visualization. They're flexible and change according to the filters and slicers you apply. Ideal for real-time calculations that shift with user interactions. 🔄

3/ 𝐂𝐚𝐥𝐜𝐮𝐥𝐚𝐭𝐞𝐝 𝐂𝐨𝐥𝐮𝐦𝐧𝐬: These static calculations apply to each row of data in your table. Think of them as formulas baked into your data—perfect for complex logic that you want to reuse across multiple visualizations. 🧩

4/ So when should you use each?
✅ Measures for real-time calculations that change based on user interaction
✅ Calculated Columns for complex calculations to reuse or when you need to drag fields into rows/columns of a visual

5/ But wait! ⚠️ Be cautious with Calculated Columns. Overusing them can slow down your data model and cause performance issues. Whenever possible, prepare your logic in Power Query or SQL instead. 🚀
