How to Calculate Average Ignore Non-Numeric Values and Errors

In daily work we often need to calculate the average of some numbers in a range for further analysis. Thus, we need to know some basic functions of calculate average in Excel. From now on, we will introduce you some basic functions like AVERAGE, AVERAGEIF, and show you some common formulas to calculate average value.

In this article, we will let you know how to calculate average by AVERAGE function easily and the way to calculate average based on a given criteria by AVERAGEIF function. We will introduce you the syntax, arguments, and basic usage about the two functions, and let you know the working process of our created formulas.


How to Calculate Average Ignore Non-Numeric Values and Errors 1

Refer to “Numbers” column, some numbers are listed in range A2:A11. C2 is used for entering a formula which can calculate the average of numbers in range A2:A11. In fact, Excel has amount of built-in functions and they can execute most simple calculations properly, and AVERAGE is one of the most common used functions.

In C2, enter “=AVERAGE(A2:A11)”.

Then press Enter, AVERAGE function returns 63.8.

You can adjust decimal places by “Increase Decimal” or “Decrease Decimal” in “Number” section.

But if some errors or blank or non-numeric values exist in the list, how can we only calculate average for numbers ignoring the invalid values?  See example below.

How to Calculate Average Ignore Non-Numeric Values and Errors 5

We get an error when calculating average for range A2:A11, the difference is there are some invalid values in the list. To calculate average ignoring the errors, that means we need to calculate average of numbers in a range with one or more criteria, thus, we can apply AVERGAEIF function instead of basic AVERAGE function.



Step 1: In C2, enter the formula =AVERAGEIF(A2:A11,”>0″).

You can also name range “Numbers” for A2:A11, then you can enter =AVERAGEIF(Numbers,”>0″).

Step 2: Press Enter after typing the formula.

How to Calculate Average Ignore Non-Numeric Values and Errors 7

Ignore the improper cells, and only calculate the average of numbers 54, 40, 88, 76, 100, 90 and 44, total 7 numbers. (54+40+88+76+100+90+44)/7=70.3. The formula works correctly.


AVERAGEIF function is AVERAGE+IF. It returns the average of some numbers in a range based on given criteria.


=AVERAGEIF(range, criteria, [average_range])

It supports wildcards like asterisk ‘*’ and question mark ‘?’, also supports logical operators like ‘>’,’<’. If wildcards or logical operators are required, they should be enclosed into double quotes (““), in this case we entered “>0” to show the criteria.



This example is very simple, we have only one list. A2:A11 is criteria range and average range.

In the formula bar, select “A2:A11”, press F9, values in this range are expanded in an array.

If average range=criteria range, average range can be omitted.


Obviously, the criteria in our case is “>0”, this condition can filter numbers from criteria range.


After expanding values, the formula is displayed as:


Note: blank cell is recorded as 0 in the array.

Because of criteria “>0”, so invalid cells are ignored. Replace all invalid values with 0. Keep all numbers.

{54;40;#N/A;88;”ABC”;76;0;100;90;44} -> {54;40;0;88;0;76;0;100;90;44}

Now this new array only contains numbers. We can calculate the average now.


1. AVERAGE function is used for returning the average of some numbers in Excel.

2. AVERAGEIF function returns the average of some numbers refer to given criteria.

3. For argument, if range=average range, average range can be omitted.

4. AVERAGEIF can support wildcards, logical operators.
