Calculated Table for Month over Month Changes

[bw70316]

I have a table of this:

July: $1,959,814

August: $3,925,980

September: $5,855,582

October: $7,910,275

November: $9,155,231

TOTAL:$28,806,885

It is taking the previous month total and adding on the current month's expenses. How do I get a table that does the following:

July: $1,959,814
August= August Total-July= NUMBER I WANT
Sept Total = (August +July) - Sept = NUMBER I WANT
ETC.

The total at the end should be 9,155,231 and each month should be 1.8 to 2.1M based on the subtraction of each month.

Basically, how do I get the difference from month to to month without having to create a SUM('Expenses'[Expensed]),'Expenses'[Month] = "July" and subtracting the difference for each month??

Would depend on your data and your calculations. Please see this post regarding How to Get Your Question Answered Quickly: https://community.powerbi.com/t5/Community-Blog/How-to-Get-Your-Question-Answered-Quickly/ba-p/38490

Thanks for responding! I would simply like the difference or the month's total sales by month, and not a cummulative figure. For example, I am currently getting the following output:

Revenues Received	MONTH
$9,061,289.66	11
$8,924,656.07	10
$7,099,541.62	9
$5,301,671.96	8
$3,804,197.98	7

What I would Like is:

Revenues Received	MONTH
$136,633	11
$1,825,114.45	10
$1,797,870	9
$1,497,474	8
$3,804,197	7

The ACTUAL Sales by Month and not a cummlative total

Hi bw70316,

To achieve your requirement, you can create a calculate column using DAX formula below:

Column = 
VAR Previous_Month_Revenues = CALCULATE(MAX(Table1[Revenues Received]), FILTER(Table1, Table1[MONTH] = EARLIEST(Table1[MONTH]) - 1))
RETURN
Table1[Revenues Received] - Previous_Month_Revenues

This is likely a workable solution, unfortunately I didn't realize you needed my complete data set as these monthly expenditures are the result of a combination of several expenditure items. When I tried this equation, the column that matched was included several times for the different items.

I was able to achieve my desired result with the following DAX:

TotalRev2 =

VAR CumRev =

CALCULATE([Sum Rev Rec.], FILTER(ALL(Revenues), Revenues[MonthNUM]=MAX(Revenues[MonthNUM])-1))

VAR CurRev= [Sum Rev Rec.]

RETURN

(CurRev-CumRev)
