You can use the following formula to calculate the average value of a range in Google Sheets only if every cell in the range is not blank:

**=IF(COUNT(A1:A10),AVERAGE(A1:A10),0)
**

This formula calculates the average value of cells in the range **A1:A10**. If every value in the range is blank, then the formula simply returns **0**.

You could also use the following formula to return a blank instead:

**=IF(COUNT(A1:A10),AVERAGE(A1:A10),"")**

The following examples show how to use these formulas in practice.

**Example 1: Average If Not Blank (Return a Value)**

The following screenshot shows how to calculate the average value in column B where there are only a few missing values:

Since there were only a few missing values, the formula simply returned the average of the non-missing values.

**Example 2: Average If Not Blank (Return a Zero)**

The following screenshot shows how to calculate the average value in column B where every single value is missing:

Since every single value was missing in column B, the formula simply returned a value of 0.

**Example 3: Average If Not Blank (Return a Blank)**

The following screenshot shows how to calculate the average value in column B where every single value is missing:

Since every single value was missing in column B, the formula simply returned a blank.
