**Please Note: **
This article is written for users of the following Microsoft Excel versions: 2007, 2010, and 2013. If you are using an earlier version (Excel 2003 or earlier), *this tip may not work for you*. For a version of this tip written specifically for earlier versions of Excel, click here: Averaging Values for a Given Month and Year.

George has a worksheet that includes dates (in column A) and values associated with those dates (in column B). The worksheet includes values for the last several years. He would like to calculate the average of all the values for a given month in a given year. For instance, George would like to calculate the average of all the values for May 2014.

There are several different ways to approach this problem. One way is to create a PivotTable based on your data. (PivotTables are great for aggregating and analyzing huge amounts of data.) You can easily set the value field to Average (instead of the default Sum) and group the Dates column by whatever you want.

If you'd rather not use a PivotTable, there are any number of formulas you can add to your worksheet. For instance, the following formula uses the SUMPRODUCT function to calculate the average:

=SUMPRODUCT((MONTH(A2:A1000)=5)*(YEAR(A2:A1000)=2011)*(B2:B1000)) / (SUMPRODUCT((MONTH(A2:A1000)=5)*(YEAR(A2:A1000)=2011)*1))

The formula assumes your dates and values begin in row 2 (to allow for headings) and don't go past row 1000. If there are no dates in the data that are in the month of May 2014, then the formula returns a #DIV/0! error.

Another approach is to use an array formula, such as the following:

=AVERAGE(IF((MONTH(A2:A1000)=5)*(YEAR(A2:A1000)=2014),B2:B1000))

This approach is shorter than the SUMPRODUCT formula, but you've got to remember to hold down **Ctrl+Shift+Enter** as you enter the formula. You'll also get the division by zero error if there is no data for the desired month and year.

Still another approach is to use one of the database functions of Excel, DAVERAGE. All you need to do is set up a criteria table that defines what you are looking for. Assume, for example, that the headings on the columns are something original, like Date (cell A1) and Value (cell B1). You could set up a criteria table in another place, such as D1:E2. The table could look like this:

Date Date >4/30/14 <6/1/14

The criteria table says that you want DAVERAGE to use anything in which the Date column contains a date greater than 4/30/14 and a date less than 6/1/14. Here's the formula:

=DAVERAGE(A1:B1000,"Value",D1:E2)

The first parameter defines your database, the second parameter indicates that you want to average the information in the Value column (column B), and the third parameter tells DAVERAGE where your criteria table is located.

One quite easy way is to apply filtering of dates and use the SUBTOTAL function. Enter the following formula into a cell:

=SUBTOTAL(101,B2:B1000)

Select a cell in your data range and filter your data (display the Data tab of the ribbon and click the Filter tool). Click the filtering arrow at the top of column A and then choose Date Filters | Custom Filter from the drop-down list. Excel displays the Custom AutoFilter dialog box. (See Figure 1.)

** Figure 1.** The Custom AutoFilter dialog box.

Use the controls in the dialog box to specify that you want records greater than 4/30/14 and less than 6/1/14. When you click on OK, only those records within May 2014 are displayed, and the subtotal formula shows the average of those visible records.

Perhaps the simplest approach, however, is to use the AVERAGEIFS function. It allows you to calculate an average of some values depending on whether an associated value (the date, in this case) meets the criteria you specify. Here's how the formula looks:

=AVERAGEIFS(B2:B1000,A2:A1000,">30 Apr 2014",A2:A1000,"<01 Jun 2014")

Notice that this is not an array formula and you don't need to define a criteria table for your criteria—they are built directly into the formula.

I used the DAX Parent Child Hierarchy DAX Model from this link https://www.daxpatterns.com/parent-child-hierarchies/ to build my own Organization GOALS Heirarchical Data Model

In the measure formula as explained in the above link, I replaced the SUM with AVERAGE

Original Formula as per the above link

[Sales Amount Simple] :=

IF (

[BrowseDepth] > [MaxNodeDepth],

BLANK (),

SUM ( Transactions[Amount] )

)

Changed Formula

[GoalsAchieved] :=

IF (

[BrowseDepth] > [MaxNodeDepth],

BLANK (),

AVERAGE( ConsolidatedGoals[Actual] )

)

However the result is not exactly as per the required average.

Can someone help me with a solution

What do you, exactly, mean by the term "WEEK" ?

Do you mean 7 consecutive dates OR Monday-Friday ?

By presenting a sample Workbook, which has some hand-types results, you can make our support-efforts much easier.

You can upload such a B to some File Hosting site and return to present the download link to us.

Your ideas here work if we are looking for average for a certain given months. I am tracking blood glucose levels for different patients. I need a weekly average and monthly average. There are 2 to 4 readings per day at different times. I just cannot average over previous x number of readings as the number of readings/day varies.

Thanks for you feedback.

For dates in Column A and values in column B - the following ARRAY FORMULA is one option to calculate the Average for the year 2015:

=SUM((YEAR(A:A)=2015)*B:B)/SUM(N(YEAR(A:A)=2015))

I have the same problem like Alvina. Normally I use Filter and then AVERAGE function to calculate averages in each year and it's too boring and time-consuming when I have to do that for 30 years. Would you please show an easier method to calculate annual average automatically?

Best Regards

Thank you very much for the wonderful tip.

If i want to calculate the average values for 12 months of each year instead of one particular month, how should the array formula look like?

Many thanks,

Alvina
