Simple Variance Analysis

[rocky84]

Hello all,

Hoping for some help as I am new to Power BI. I am being encouraged to use this at work for some simple financial analysis, but am struggling to do some standard variances, which i used to do easily in excel. Example:

Product Number	July	Aug	Variance	% Variance
123	100	120	20	20%
456	2500	4000	1500	60%

How do I create the variance and % variance columns in PowerBI? (Apologies if this is a basic question and asked many times before!)

thanks in advance

@rocky84 , You have create measure for this month and last month and use those

examples measures

MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD('Date'[Date]))
last MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(dateadd('Date'[Date],-1,MONTH)))
last month Sales = CALCULATE(SUM(Sales[Sales Amount]),previousmonth('Date'[Date]))

this month = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(ENDOFMONTH('Date'[Date])))
last MTD (complete) Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(ENDOFMONTH(dateadd('Date'[Date],-1,MONTH))))

Variance

diff = [MTD Sales]-[last MTD Sales]
diff % = divide([MTD Sales]-[last MTD Sales],[last MTD Sales])
