What is DAX?
DAX stands for Data Analysis Expressions — a collection of functions, operators, and constants used in Power BI, Excel Power Pivot, and Analysis Services. It allows users to build formulas and expressions that define custom calculations, going beyond simple aggregation like SUM or AVERAGE.
Unlike Excel formulas, DAX works with data models that understand relationships between tables, enabling cross-table computations and time intelligence analysis. It helps you answer complex questions such as:
- What is the sales growth percentage year-over-year?
- Who are my top-performing customers?
- How does profit margin trend by region over time?
Here’s a list of 10 different examples of using DAX (Data Analysis Expressions) in Power BI, spanning common calculations, time intelligence, filtering, and more.
1. Calculated Column: Profit
Create a new column to calculate profit per row:
Profit = Sales[Revenue] - Sales[Cost]
✅ Simple arithmetic for row-level calculations.
2. Measure: Total Sales
Aggregate total sales across your data:
Total Sales = SUM(Sales[Revenue])
✅ Measures are dynamic and adjust with filters.
3. Measure: Year-to-Date (YTD) Sales
Use time intelligence to calculate cumulative sales:
Sales YTD = TOTALYTD(SUM(Sales[Revenue]), 'Date'[Date])
✅ Great for comparing performance over time.
4. Measure: Percentage of Total
Calculate the contribution of each category to total sales:
Sales % of Total = DIVIDE(SUM(Sales[Revenue]), [Total Sales], 0)
✅ DIVIDE avoids divide-by-zero errors.
5. Calculated Column: Sales Category
Categorize sales into buckets:
Sales Category =
IF(Sales[Revenue] > 1000, "High", "Low")
✅ Useful for segmentation and conditional logic.
6. Measure: Running Total
Calculate cumulative sales over time:
Running Total =
CALCULATE(
SUM(Sales[Revenue]),
FILTER(
ALL('Date'),
'Date'[Date] <= MAX('Date'[Date])
)
)
✅ Dynamic running totals for line charts.
7. Measure: Sales Last Year
Compare this year vs last year:
Sales LY = CALCULATE(SUM(Sales[Revenue]), SAMEPERIODLASTYEAR('Date'[Date]))
✅ Perfect for trend analysis.
8. Measure: Count of Unique Customers
Count distinct values:
Unique Customers = DISTINCTCOUNT(Sales[CustomerID])
✅ Useful for customer analytics.
9. Measure: Filtered Measure
Calculate sales only for a specific product category:
Sales Electronics = CALCULATE(SUM(Sales[Revenue]), Sales[Category] = "Electronics")
✅ CALCULATE changes context for flexible metrics.
10. Measure: Average Sales per Customer
Combine aggregation and distinct counts:
Avg Sales per Customer = DIVIDE([Total Sales], [Unique Customers], 0)
✅ Useful for deriving customer-level KPIs.
