While working with Excel, we are able to average values that satisfy a given criteria by using the **AVERAGEIF **function. This step by step tutorial will assist all levels of Excel users in the usage and syntax of AVERAGEIF function.

*Figure 1. Final result: Excel AVERAGEIF function*

**Formula 1:** **=AVERAGEIF(C3:C9,E3,C3:C9)**

**Formula 2:** **=AVERAGEIF(B3:B9,E4,C3:C9)**

**Syntax of the AVERAGEIF Function**

`=`

**AVERAGEIF**(**range**, **criteria**, [**average_range**])

**range**– the data range that we will evaluate using the criteria**criteria**– the criteria or condition that determines which cells will be averaged**average_range**–*optional*; the cells that will be averaged; if left blank, “average_range” = “range” which means that the range of data that will be averaged is the same range of data evaluated

**Setting up our Data**

Our data consists of two columns : Date (column B) and Output (column C). In cells E3 and E4, we enter the criteria for our AVERAGEIF function. We want to calculate the average of outputs greater than 500 and the average of outputs on January 3. The results will be recorded in cells F3 and F4.

* Figure 2. Sample data for the AVERAGEIF function*

**Calculate the average of outputs greater than 500**

We want to calculate the average of outputs greater than 500 by using the AVERAGEIF function. Let us follow these steps:

**Step 1**. Select cell F3

**Step 2**. Enter the formula: `=AVERAGEIF(C3:C9,E3,C3:C9)`

**Step 3**. Press ENTER

* Figure 3. Using AVERAGEIF to calculate the average of outputs > 500*

The data range that we will evaluate is **C3:C9**. Our criteria in cell E3 is “**>500**”, which finds outputs greater than 500. The data range of values we want to average is also **C3:C9**, which contains the outputs.

As a result, our formula calculates the average of **600**, **700**, **750 **and **800**. Finally, the result in cell F3 is **712.5**, which is the average of the four values.

**Calculate the average of outputs on January 3**

We want to calculate the average of outputs produced on January 3. Let us follow these steps:

**Step 1**. Select cell F4

**Step 2**. Enter the formula: `=AVERAGEIF(B3:B9,E4,C3:C9)`

**Step 3**. Press ENTER

* Figure 4. Using AVERAGEIF to calculate the average output on 3-Jan*

The data range that we will evaluate is **B3:B9**. Our criteria in cell E4 is “**3-Jan**”. The data range of values we want to average is **C3:C9**, which contains the outputs.

As a result, our formula calculates the average of **700 **and **750**, which are the outputs on 3-Jan. Finally, the result in cell F4 is **725**, which is the average of the two values.

**Notes:**

- Cells that are empty, or cells containing TRUE or FALSE are ignored
- AVERAGEIF allows the use of wildcard characters such as the question mark “?” (means a single character) and asterisk “*” (means any number of characters)
- If no cells in the range meet the criteria, AVERAGEIF returns the error value #DIV/0!
