# Power BI Average Article byJeevan A Y ## Average Function in Power BI

Some of the formulas in MS Excel are directly incorporated into Power BI as well, in fact, there is a group of formulas that are exactly the same both with MS Excel and Power BI. In this article, we are going to discuss one of the i.e. AVERAGE DAX Function in detail.

### What Does AVERAGE Function Do in Power BI?

This is very simple this will aggregate the column that we mention and takes the average value of numerical values. For example, if an employee has achieved 100 K USD sales value in 12 months then using the we can get the average sales amount for that particular employee.

Column is simply the numerical column that we need to take the average of.

Since the AVERAGE function takes only numerical values for its evaluation we need to be aware of non-numerical values and their behavior, below are the points to be kept in mind with the non-numerical values column.

• Any column which contains non-numerical values is ignored for aggregation and DAX function returns the blank result.
• Logical results like TRUE & FALSE are ignored from the .
• Empty cells are ignored from calculation and cells with 0 are considered for calculation purposes.

### Examples of AVERAGE Function in Power BI

Below are examples of the average function in Power BI. You can download the workbook to use the same file as we used in this example.

#### Example #1

We are going to use the above data to demonstrate the AVERAGE function in Power BI, you can download the excel workbook to practice along with us.

Steps to use an Average function in Power BI are as follows.

1. Upload the above data table to the Power BI file. This data table name is “Sales_Table”. 2. First, insert table visual to show employee-wise sales values. 3. Now we will try to find the average sales value per month of each employee. Right-click on the table and choose “New Measure”. 4. For this new measure give the name “Average Sales per Month”. 5. Open the AVERAGE function now. 6. For this AVERAGE function we simply need to choose the column that we need to take the average of, so choose the “Sales” column. 7. Close the bracket and hit enter key to get the result. Now measure is created in the table. 8. Drag and drop this new measure to the existing table to get each employee average sales. Here we have average sales for each employee.

One more thing you need to know here is without entering the AVERAGE DAX function also we can get the average total of each employee.

After dragging and dropping the “Sales” column to the field of the table or any other visual click on the drop-down list of the “Sales” column in the fields section.

As soon as you click on this drop-down list we can see these options for this column.

As of now “SUM” is the current set of actions is performed, so simply choose the option of “Average” to get the average value instead of overall summation of values.

As soon as you choose this option our visual shows the average values not overall sales values.

#### Example #2

Now scenario situation where you need to create an average for each individual employee i.e. conditional average measure. For example, we need to find the average only for the employee “Ricky”.

So, this can be done by using CALCULATE and FILTER functions along with the AVERAGE function.

Right-click on the table and choose New Measure and give the name to this measure as “Avg of Ricky”.

Open the CALCULATE function.

Expression is nothing but the kind of calculation that we need to perform, in this case, we need to perform AVERAGE calculation, so open AVERAGE function now.

Choose the necessary column that needs to be considered for average, in this case, the “Sales” column.

Next, we need to apply the FILTER function to specify for which employee we need to take the average of, so open FILTER function.

Mention the table name as “Sales_Table”.

For Filter Expression choose the “Sales Person” column.

To apply the filter for one specific employee i.e. “Ricky” put the equal sign and enter the employee name in double-quotes.

Ok, that’s all close two brackets and hit enter key to get the result.

Now to see how Average DAX measure functioning in power BI will drag and drop this new measure to the existing table.

As you can see above only for the employee “Ricky” new measure showing the average value.

Note: Power BI dashboard file can also be downloaded from the link below and the final output can be viewed.

• Empty cells are ignored and cells with zero value are considered for average calculation.
• Conditional average performed along with CALCULATE and FILTER function.
