Calculated Field in Pivot Table

[tcalleia]

I can't figure out how to do a calculated field on individual months when my field is simply "month" and not the individual months:

My data looks like this with the months in one column- not seperate columns for each month:

When I pivot I can see the months in columns like this:

but when I try to do a calculated field like Jan11 vs. Jan12 of Jan-Mar 2011 vs. Jan-Mar 2012 the months do not show as available fields for calculating; I only see "Month".

I tried calculated "item" but this totally freezes up excel so I was hoping I can find some way to do this as a calculated field.
Thanks for your help

Hi,

What version of Excel are you using?

I took you data although I got some concerns with the formatting of the date but it might be due to a simple difference in between EU and US versions.

Please clarify:
"calculated field like Jan11 vs. Jan12 of Jan-Mar 2011 vs. Jan-Mar 2012"

What exactly would you like to compute? the difference? a percentage?
Jan year1 versus Jan year+1?
Jan year1 vs other months same same?

Thanks to clarify!

Hi Cyrilbrd,
Sorry- forgot to post the version
I'm using excel 2010. I want to compute this:

(Jan12+Feb12+Mar12)-(Jan11+Feb11+Mar11)

Thanks for your help

Hi,

You must rearrange your raw data. Calculated fields will work only with Fields name, so here in your example the Fields are " Item, Month and Sale$".
Therefore it is impossible for this set of data to compute the difference of two sum since they are data within field.

The answer to your query would be as follows:

6,632.64	7,028.06	-395.42
5,593.68	5,132.23	461.45
6,350.40	6,887.52	-537.12

That is the first Column is the sum of Jan to Mar of year x+1
The second Column is the sum of the same months for year x
And the last column is the difference of (year x+1) - (year x).

To be able to get this with the pivot I suggest this:
Your Raw Data:

Item	Jan-12        	Feb-12       	Mar-12       	Jan-11      Feb-11	Mar-11
Item 1	3,146.40	1,339.20	2,147.04	3,461.04	1,205.28	2,361.74
Item 2	2,343.60	489.6         	2,760.48	2,109.24	538.56	2,484.43
Item 3	4,536.00	489.6         	1,324.80	4,989.60	440.64	1,457.28

And the pivot using calculated fields:

Sum of tcalleia	
Row Labels	Total
Item 1        	-395.42
Item 2        	461.45
Item 3        	-537.12
Grand Total	-471.09

Is this what you needed?

Thanks a lot for your help I was trying to do without re-arranging the raw data. I guess I'll need to do a pivot on raw to get the months in different columns and then use that data to do my pivot with the calculated fields.

Thanks!!!

Glad it worked for you.

Cheers!
