PRODUCTX

Calculates the product of an expression evaluated for each row in a table.

What is the PRODUCTX Function?

The PRODUCTX function in DAX is like a skilled chef, taking individual ingredients from each row and multiplying them together based on a specified expression. It allows for dynamic calculations, making it ideal for scenarios where the values depend on other columns in your dataset! 🍽️✨

Example 1: Total Investment Growth with Contributions

Imagine you’re evaluating the growth of various investments where each investment has a different initial amount and a growth factor. Here’s how your data might look:

To find the total revenue from these investments after growth, you would use the PRODUCTX function like this:

Total Revenue = 
PRODUCTX(InvestmentGrowth, 
InvestmentGrowth[Initial Amount ($)] * 
InvestmentGrowth[Growth Factor])

In this scenario, the function evaluates the expression for each row, calculating the revenue for each investment:

In this scenario, the function evaluates the expression for each row, calculating the revenue for each investment:

• Stock A: 10,000 x 1.05 = 10,500
• Stock B: 15,000 x 1.08 = 16,200
• Stock C: 20,000 x 1.03 = 20,600
• Stock D: 5,000 x 1.10 = 5,500

Now, to find the total revenue from all investments, PRODUCTX would multiply the calculated values together:

• Total Revenue: 10,500 x 16,200 x 20,600 x 5,500 =

This would yield the overall revenue after growth based on each investment’s contribution multiplied! 💰📈

Example 2: Future Value of an Investment with Fixed Interest Rate

Imagine you’re evaluating an investment’s future value over a set number of years, where you have a fixed present value (initial investment) and a fixed interest rate applied annually. Here’s how your data might look:

Let’s say your current investment is $10,000. To calculate the future value after applying the interest rate over the annuity periods, you can use the following DAX expression:

Future Value = 
[Current Investment] * PRODUCTX(InvestmentTable, 
1 + (InvestmentTable[Fixed Interest Rate (%)]/100))

In this example, we are effectively calculating:

1. After Year 1: 10,000 x 1.05 = 10,500
2. After Year 2: 10.500 x 1.05 = 11,025
3. After Year 3: 11,025 x 1.06 = 11,706.50
4. After Year 4: 11,706.50 x 1.06 = 12,387.69

By incorporating the varying interest rates, the total future value of the investment after four years is approximately $12,387.69. 💰 🧐
