I need to add Previous Month and Previous Year Totals to my data set and Pivot Table in the attached file. Rather than the tedious Manual summing is there an Excel formula which can achieve this?

You may want to use the DATEDIF Formula to identify previous Month or Year or even Days

Hi Nathaniel,

I had already looked at that and I don't think it will work. From my limited knowledge it seems to me that somehow columns F & G are maybe an offset (???) calculation from column E which is summed by month or year (in the Pivot table???) subtracting the DATE value by 1 month or one year respectively.

For  the ONE MONTH PREVIOUS case reference value on 12 September 2015 (E377) (i.e. =sum(E345:E376 (=Sum of Revenue)) for the preceding MONTH (11 September 2015 to 10 August 2015), and
For the ONE YEAR PREVIOUS case the reference value on 12 September 2015 (i.e. =sum(E11:E377 (=Sum of Revenue)) for the preceding YEAR (11 September 2015 to 10 September 2014

Does that make it clearer?

For previous month use formula:

=SUMIFS($E:$E,$C:$C,">="&DATE(YEAR(Table_Rev[@Date]),MONTH(Table_Rev[@Date])-1,DAY(Table_Rev[@Date])+1),$C:$C,"<="&Table_Rev[@Date])

For previous 12 months use:

=SUMIFS($E:$E,$C:$C,">="&DATE(YEAR(Table_Rev[@Date]),MONTH(Table_Rev[@Date])-12,DAY(Table_Rev[@Date])+1),$C:$C,"<="&Table_Rev[@Date])

Hope that works for you.

Thanks

Hi Rob H,

The formula that you have provide work OK so technically you have answered my question. However to make this work in the context of the project I have had to put the formula in a second sheet and pivot table to get the output that I am looking for. Ultimately there are inputs which will be entered by the users for particular columns for both sheets/pivot tables through a Userform.

As you will see from the attached file the formula that you have provided are only required on the 1st day of each subsequent month which makes sheet 2 very messy to manually enter the formula.

My question/query is: an the formula be somehow 'scheduled' to only occur on the 1st day of each calendar month from sheet 1 rather than partially duplicating the data into sheet 2?

Any idea why the file is so big???

Thanks,
Paul
