How to Find Average of the Last 3 Values in Microsoft Excel 2010

In this article, we will learn How to Find the Average of the Last 3 Values in Microsoft Excel 2010.

Scenario

For Instance, you have a large list of data and you need to find the Average of the numbers from last 3 particular month.

Function and formula

For this article we will be needing the use the following functions:

1. AVERAGEIFS Function
2. EOMONTH function

Excel AVERAGEIFS function is used to find the average of the array based on multiple criteria or condition.

Syntax:

 = AVERAGEIFS ( Average_range , range1, criteria1, [ range2,criteria2 ] )

The EOMONTH function is used to find the last day of the given month. It requires two things:

1. From date you wish to count or manufacturing date.
2. Number of months from the date or its living period.

Syntax:

 =EOMONTH( Start_date, months)

start_date : a valid date representing the start date for the function.

Months : a positive or negative number to get the date for after or before the start date.

Now we will make a formula out of these functions. Here we will given the data and we needed to find the AVERAGE of the numbers in a particular month.

Use the formula:

 = AVERAGEIFS ( rng , order_date , ">=" & date , order_date , "<=" & EOMONTH ( date , 0 ) )

Explanation:

• EOMONTH function returns the end of the month date of the date given as argument.
• AVERAGEIFS takes the average of the numbers between having date greater than given date and less than the end of the month date.

Notes: do not provide date directly to the function. Use DATE function or use cell reference for date argument in excel as Excel reads date only with the correct order.

Example :

All of these might be confusing to understand. Let's understand how to use the function using an example. Here Here we have a data from A1:D51. we need to find the AVERAGE of Quantity in the month of January. First we will find a date which has the first date of the month which is the A2 cell. Named ranges are rng ( D2 : D51 ) and order_date ( A2 : A51).

Use the Formula:

 = AVERAGEIFS ( rng , order_date , ">=" & A2 , order_date , "<=" & EOMONTH ( A2 , 0 ) )

Explanation:

• EOMONTH (A2, 0) returns the 31st January as the last date in January.
• ">=" & A2 returns a criteria that the value greater than date in A2.
• "<=" & EOMONTH ( A2 , 0 ) ) returns a criteria that the value less than the end of the month date.
• AVERAGEIFS takes all the above arguments and returns the average of the number given below.

{ 33 ; 87 ; 58 ; 82 ; 38 ; 54 ; 149 ; 51 ; 100 ; 28 ; 36 }

Here the A2 is given as cell reference & Named ranges given as rng ( D2 : D51 ) and order_date ( A2 : A51). As you can see in the above snapshot the AVERAGE of the quantity in January comes out to be 65.091 .

Now we will get the AVERAGE of the quantity in February by changing the First date argument of the function

Use the Formula:

 = AVERAGEIFS ( rng , order_date , ">=" & A13 , order_date , "<=" & EOMONTH ( A13 , 0 ) ) As you can see in the above snapshot the AVERAGE of the quantity in January comes out to be 43.778 .

Notes:

1.  The function returns #VALUE! error if the argument to the function is non-numeric.
2. Do not provide date directly to the function. Use DATE function or use cell reference for date argument in excel as Excel reads date only with the correct order.
