Averages and Percentage differences

[Anonymous]

Hi all, i was wondering how to create a measure in Power BI that would calculate the average of my values based on 3 different different criteria. Once i have this i would also like to be able to find out the % differences between these values. 

I essentially want to find the percentage difference between the average value of something in January 2021 compared to january 2022.

Any help with this would be appreciated, thanks.

@Anonymous , You van use year behind measure

Year behind Sales = CALCULATE(Average(Sales[Sales Amount]),dateadd('Date'[Date],-1,Year))
Year behind Sales = CALCULATE(Average(Sales[Sales Amount]),SAMEPERIODLASTYEAR('Date'[Date]))

or

last year MTD Sales = CALCULATE(Average(Sales[Sales Amount]),DATESMTD(dateadd('Date'[Date],-12,MONTH)))
Previous year Month Sales = CALCULATE(Average(Sales[Sales Amount]),previousmonth(dateadd('Date'[Date],-11,MONTH)))
last year MTD (complete) Sales = CALCULATE(Average(Sales[Sales Amount]),DATESMTD(ENDOFMONTH(dateadd('Date'[Date],-12,MONTH))))
