How to Calculate a Moving Range in Excel (4 Methods)

We have a dataset of some Product List and their Total Sales in quantity. We are going to calculate the moving range using formulas.

Steps:

Choose a cell to apply the formula. Here, I have selected cell (D7) as we take 3 intervals to get out the moving range value.
Enter the following formula:

=AVERAGE(C5:C7)

Where,

The AVERAGE function returns the average value inside a given string. Here, we have provided the cells (C5:C7); thus, the average value for the cells is “67.”

Press Enter to get the output.
Drag down the “fill handle” to fill all the cells with the moving range.

We have successfully calculated the moving range, indicating the average sales quantity from the product list.

In the new dialog box, choose your “Input Range” cells (C5:C13).
Choose an interval as we determine the average value with 3 values. We put “3” in the “Interval” section.
Select the “Output Range” from your dataset to view your calculated output.
Check mark the “Chart Output” if you want to get the chart in your worksheet.
Press OK.

Steps:

=AVERAGE(OFFSET(C5,COUNT(C5:C100)-3,0,3,1))

Formula Breakdown:

COUNT(C5:C100)→ In this part the COUNT function is counting how many values are available in Column C and providing an output-”9” as we have a total of 9 values in the column.
OFFSET(C5,COUNT(C5:C100)-3,0,3,1)→ The OFFSET function takes the cell reference C5 and then selects the range by taking the starting and ending point from the argument to calculate.
Here, “-3” indicates 3 rows up, “0” order to stay in the same column, “3” means consisting of total 3 rows, and “1” indicates a total of 1 column.
AVERAGE(OFFSET(C5,COUNT(C5:C100)-3,0,3,1))→ In the end, the AVERAGE function returns the average value from the selected cells in the range.

Steps:

=IF(ROW()-ROW($C$5)+1<3,NA(),AVERAGE(C5:C7))

Where,

The IF function generates values with the help of the ROW and AVERAGE functions. If the value for this argument “ROW()-ROW($C$5)+1” is less than “3,” then show “#N/A,” and if not, display the average value.

Things to Remember

If you haven’t enabled the “Data Analysis” option, you won’t be able to enjoy the fantastic feature. To enable it, go to File > Options > Add-ins. From there, choose “Analysis Toolpak” and click OK. That’s it.
