You can use the following formula to combine the **SUBTOTAL** and **AVERAGEIF **functions in Excel:

=AVERAGE(IF(SUBTOTAL(2,OFFSET(C2,ROW(C2:C11)-ROW(C2),0)),IF(B2:B11="Guard",C2:C11)))

This particular formula allows you to calculate the average of values in the range C2:C11 where the corresponding value in the range B2:B11 is equal to “Guard” even after that range of cells has been filtered in some way.

The following example shows how to use this formula in practice.

**Example: How to Use SUBTOTAL with AVERAGEIF in Excel**

Suppose we have the following dataset that contains information about various basketball players:

Next, let’s filter the data to only show the rows where the players are in the **West** conference.

To do so, highlight the cell range **A1:C11**. Then click the **Data **tab along the top ribbon and click the **Filter** button.

Then click the dropdown arrow next to **Conference **and make sure that only the box next to **West** is checked, then click **OK**:

The data will automatically be filtered to only show the rows where the Conference column is equal to **West**:

If we attempt to use the **AVERAGEIF()** function to calculate the average of the values in the Points column where the value in the Position column is equal to “Guard”, it will actually return the average of points for the rows equal to “Guard” in the original dataset:

Instead, we need to use the following formula:

=AVERAGE(IF(SUBTOTAL(2,OFFSET(C2,ROW(C2:C11)-ROW(C2),0)),IF(B2:B11="Guard",C2:C11)))

The following screenshot shows how to use this formula in practice:

This formula returns the correct average of **21.25**.

We can confirm this is correct by manually calculating the average of the points values for the rows where the Position column is equal to “Guard”:

Average of Points for Guards: (12 + 28 + 30 + 15) / 4 = **21.25**.
