How to Calculate Growth in Power BI
In Power BI, you can calculate growth using various formulas and techniques. The following example demonstrates one way to calculate growth using measures and calculations in Power BI.
Example
Suppose you have a dataset with monthly sales data for a particular product. You want to calculate the monthly growth rate based on the previous month’s sales.
1. Start by creating a new measure to calculate the previous month’s sales:
PrevMonthSales = CALCULATE(SUM(SalesTable[Sales]), PREVIOUSMONTH(SalesTable[Date]))
This measure uses the CALCULATE function to calculate the sum of sales for the previous month. The PREVIOUSMONTH function is used to generate the previous month’s date context.
2. Next, create another measure to calculate the growth rate:
MonthlyGrowth = DIVIDE(SUM(SalesTable[Sales]) - [PrevMonthSales], [PrevMonthSales])
The DIVIDE function is used to divide the difference between the current month’s sales and the previous month’s sales by the previous month’s sales. This will give you the growth rate.
3. Finally, display the MonthlyGrowth measure in a visual in Power BI to see the growth rate for each month.
By following these steps and adapting them to your specific data and requirements, you can easily calculate growth in Power BI.
