Essential DAX Formulas
DAX (Data Analysis Expressions) is the formula language that powers Power BI calculations. Master these essential formulas:
// Year-over-Year Growth
YoY Growth =
VAR CurrentYear = [Total Sales]
VAR PreviousYear = CALCULATE(
[Total Sales],
SAMEPERIODLASTYEAR(Date[Date])
)
RETURN
DIVIDE(CurrentYear - PreviousYear, PreviousYear, 0)
// Running Total
Running Total =
CALCULATE(
[Total Sales],
FILTER(
ALL(Date),
Date[Date] <= MAX(Date[Date])
)
)
// Moving Average (3 months)
Moving Avg 3M =
AVERAGEX(
DATESINPERIOD(Date[Date], MAX(Date[Date]), -3, MONTH),
[Total Sales]
