You can use this approach to average the last N data points: last 3 days, last 6 measurements, etc. Given a starting reference, you can specify rows, columns, height, and width. The rows and columns arguments function like "offsets" from the starting reference. The height and width arguments, both optional, determine how many rows and columns the final range includes.

COUNT counts only numeric values, so the heading in row 3 is automatically ignored. The Excel OFFSET function returns a reference to a range constructed in parts: a starting point, a row and column offset, and a final height and width in rows and columns. Values can be supplied as constants, cell references, or ranges.

Note: the point of this formula is to eliminate the manual task of entering ranges manually with a single global formula, at the cost of a more complex formula.

For reference we use the first cell in the data range, B5, entered as a mixed reference column locked, row relative. In O5, the offset is zero, in P5, the offset is 3, and so on. Finally, height is input as 1 and width is input as 3, since in this case we always want a 1 x 3 range of cells. Note: change 3 to the multiplier you need, shown as "n" in the generic form of the formula above.

One can specify the expected number of rows and columns to be returned. The said function is a Worksheet WS function. As a WS function, it can be entered as a part of the formula in a cell of a worksheet. Refer to the examples given below to understand better. B3 is also the starting cell of the table. Rows value is 2 and the Columns value is 1.

The row that is 2 pointers below points to row number 5 and the column that is 1 pointer to the right is column C Name. So, the resultant cell is C5. B3 is also the starting cell of the worksheet. Rows value is 2 and the Columns value is 2.

The row that is 2 pointers below points to row number 5 and the column that is 2 pointers to the right is column D. So, the resultant cell is D5 but the value at D5 is not present. So, the return value is 0. Rows value is -2 and Columns value is The row that is -2 pointers above points to row number 0 and the column that is Both the row and the column does not exist in the worksheet.

So, the resultant cell F6 contains REF! The information icon in yellow colour shows Invalid Cell Reference Error. C2 is also the starting cell of the worksheet. Rows value is 0 and the Columns value is 0.

The reference from which the base is to be offset. It can be a cell or a range of adjacent cells. It can be a positive or a negative number. It represents the number of rows, the upper-left cell would refer to.In the example shown, the formula in G6 is:. In the example shown, we have monthly data for the years and The goal is to dynamically sum values through a given number of months, hardcoded as 6 in cell G5. The OFFSET function let's you build a reference using a starting point, a row and column offset, and a height and width.

OFFSET is handy in formulas that dynamically average or sum "last n values", "first n values", and so on. Translated: from a starting position of C5, build a reference 6 rows x 1 column with no offset. A generic version of this formula would look like this:. The Excel OFFSET function returns a reference to a range constructed in parts: a starting point, a row and column offset, and a final height and width in rows and columns.

The Excel SUM function returns the sum of values supplied. These values can be numbers, cell references, ranges, arrays, and constants, in any combination. SUM can handle up to individual arguments.

To average the last 3 numeric values in a range, you can use an array formula based on a combination of functions to feed the last n numeric values into the AVERAGE function.In this tutorial, we are going to shed some light on one of the most mysterious inhabitants of the Excel universe - the OFFSET function.

In a nutshell, the OFFSET formula returns a reference to a range that is offset from a starting cell or a range of cells by a specified number of rows and columns. The first 3 arguments are required and the last 2 are optional. All of the arguments can be references to other cells or results returned by other Excel formulas.

It looks like Microsoft made a good effort to put some meaning into the parameters' names, and they do give a hint at what you are supposed to specify in each. Both the height and width arguments must always be positive numbers. If either is omitted, the height or width of the starting reference is used.

The formula tells Excel to take cell A1 as the starting point referencethen move 3 rows down rows argument and 1 column to the left cols argument. The image on the left shows the function's route and the screenshot on the right demonstrates how you can use the OFFSET formula on real-life data. The only difference between the two formulas is that the second one on the right includes a cell reference E1 in the rows argument.

But since cell E1 contains number 3, and exactly the same number appears in the rows argument of the first formula, both would return an identical result - the value in B4.

However, if you embed it into the SUM function, like this:. The formula will return the sum of values in a 1-row by 3-column range that is 3 rows below and 1 column to the right of cell A1, i. Creating dynamic ranges : References like B1:C4 are static, meaning they always refer to a given range. But some tasks are easier to perform with dynamic ranges.

This is particularly the case when you work with changing data, e. Getting the range from the starting cell.

Sometimes, you may not know the actual address of the range, though you do know it starts from a certain cell. I hope you haven't get bored with that much of theory. Now, let's look at these functions at another angle and see what else they can do. When working with continuously updated worksheets, you may want to have a SUM formula that automatically picks all newly added rows. Suppose, you have the source data similar to what you see in the screenshot below. Every month a new row is added just above the SUM formula, and naturally, you want to have it included in the total.

Since the first cell of the range to sum will be specified directly in the SUM formula, you only have to decide on the parameters for the Excel OFFSET function, which will get that last cell of the range:.

And as demonstrated in the below screenshot, it works flawlessly:. In the above example, suppose you want to know the amount of bonuses for the last N months rather than grand total. You also want the formula to automatically include any new rows you add to the sheet. COUNT returns the number of cells in column B that contain numbers, from which you subtract the last N months the number is cell E1and add 1.We want to allow the user to enter the number of rows to include.

We want to write a formula that computes the average of the desired number of rows. This is illustrated below. For example, if we wanted to start at A10, move down 3 rows and move right 1 column, we could use the following function.

If we wanted to start at A10, move up 2 rows, move right 0 columns, set the total number of rows to 3, and the total number of columns to 1, we could use the following function. Next, we want to write a formula to populate the MovingAvg column. Instead of using an A1-style reference, such as A10, we reference the amount cell for the current row with a structured table reference.

When you click the cell, Excel inserts the correct table reference, such as [ Amount].

For example, we could write the following formula into the first table row. However, that would fix the number of months within the formula, and, since we want to make it easy for the user to change the number of months in our average, we store the months value in cell C5, and then update our formula as follows.

When we add another table row, Excel automatically fills the MovingAvg formula down, as shown below. With the formula above, the OFFSET function creates a range for the first few table rows that may extend above the table. For example, the formula in the first table row begins a few rows above the table. As long as there are enough non-numeric cells above the Amount column, there is no issue. This is done by computing the row number with the ROWS function, and then returning the MIN between that number of rows and the desired number of rows.

The updated formula is shown below for reference, and is also included in the sample Excel file. This is great, because now the user can specify the desired number of months, and our moving average formula will update accordingly. The basic idea here is that the OFFSET function is volatile, which means Excel recalculates it anytime any value has changed, whereas, non-volatile functions are recalculated when precedent cells have changed.

In summary, for small workbooks either function would probably be just fine, however, in large workbooks it is best practice to avoid volatile functions when possible. The basic idea here is that we use the range operator to define the range, and the first side is the amount value in the current row. Then we use the INDEX function to return a reference to the cell that is say two rows above that cell.

What about adding a moving average column to a pivot table?

I have a pivot table that shows expense rates by month for the last 6 months for each of 30 profit centers. For each profit center, I want to show the 3-month moving average of the expense rates, so that I can use the moving average for forecasting. Got any ideas?
