AVERAGEIFS question by month/year

[eduzs]

Hi,

I need a formula to calculate the average value of a column given a month/year.

03/15/2014	10
03/20/2014	20
04/10/2014	30
04/18/2014	50
06/30/2014	30

<tbody>
</tbody>

Averageifs moth = 3 and year 2014 = 10 + 20 + 30 / 3 = 20

Averageifs moth = 4 and year 2014 = 30 + 50 / 2 = 40

Thanks.

Assuming that A2:B6 contains the data, try...

=AVERAGEIFS($B$2:$B$6,$A$2:$A$6,">="&DATE(2014,3,1),$A$2:$A$6,"<="&DATE(2014,3,31))

or

=AVERAGEIFS($B$2:$B$6,$A$2:$A$6,">="&DATE(E2,D2,1),$A$2:$A$6,"<="&DATE(E2,D2+1,0))

...where D2 contains the month, such as 3, and E2 contains the year, such as 2014.

Hope this helps!

Just an alternative:

Excel 2010
	A	B	C	D
1	03/15/2014	10	03/01/2014	15
2	03/20/2014	20	04/01/2014	40
3	04/10/2014	30
4	04/18/2014	50
5	06/30/2014	30
