How to average last 5 values of a column as new numbers entering?

In Excel, you can quickly calculate the average of last 5 values in a column with the Average function, but, from time to time, you need to enter new numbers behind your original data, and you want the average result will be changed automatically as the new data entering. That is to say, you would like to have the average always reflect the last 5 numbers of your data list, even when you add numbers now and then.

The following array formulas may help you to solve this problem, please do as follows:

Enter this formula into a blank cell:

=IF(COUNT(A:A),AVERAGE(INDEX(A:A,LARGE(IF(ISNUMBER(A1:A10000),ROW(A1:A10000)),MIN(5,COUNT(A1:A10000)))):A10000),"no data") (A:A is the column which contains the data you used, A1:A10000 is a dynamic range, you can expand it as long as your need, and the number 5 indicates the last n value.), and then press Ctrl + Shift + Enter keys together to get the average of last 5 numbers. See screenshot:

doc-average-last-5-1

And now, when you input new numbers behind the original data, the average will be changed as well, see screenshot:

doc-average-last-5-2

Note: If the column of cells contain 0 values, you want to exclude the 0 values from your last 5 numbers, the above formula will not work, here, I can introduce you another array formula to get the average of last 5 non-zero values, please enter this formula:

=AVERAGE(SUBTOTAL(9,OFFSET(A1:A10000,LARGE(IF(A1:A10000>0,ROW(A1:A10000)-MIN(ROW(A1:A10000))),ROW(INDIRECT("1:5"))),0,1))), and then press Ctrl + Shift + Enter keys to get the result you need, see screenshot:

    =IF(COUNT(A:A),AVERAGE(INDEX(A:A,LARGE(IF(ISNUMBER(A1:A10000),ROW(A1:A10000)),MIN(5,COUNT(A1:A10000)))):A10000),"no data")

    Does not work for me.

    Here is my version:
    =IF(COUNT(C:C),AVERAGE(INDEX(C:C,LARGE(IF(ISNUMBER(C2:C10000),ROW(C2:C10000)),MIN(5,COUNT(C2:C10000))))):C10000)

    The error I get is: Wrong data type.
