INDEX Value from SAMEPERIODLASTYEAR

Hi, with plenty of help from here, i have made an Percentage deviatione from SAMEPERIODLASTYEAR:

 

Calculating numerical value SAMEPERIODLASTYEAR :

Samme periode sidste år = CALCULATE((SUM(Data[Antal rejser]));SAMEPERIODLASTYEAR(Kalender[Date]))

 

Percentage deviation

Pct. afvigelse - samme periode sidste år = DIVIDE(SUM(Data[Antal rejser]) - 'Variabler - ordning'[Samme periode sidste år]
; 'Variabler - ordning'[Samme periode sidste år]
; BLANK())

 

however what would be easy to create in Excel is not so easy for my limited DAX knowledge;

 

I want to create a formula where the SAMEPERIODLASTYEAR value is the Index value = 100, example January 2019 = 100 , Januray 2020 = 83

 

 

I have tried with adding *100 to the formula to no avail, could you please help?

    Not very clear with your formula. You can try like these example with date table

    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 year MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(dateadd('Date'[Date],-12,MONTH)))
last year MTD (complete) Sales =  CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(ENDOFMONTH(dateadd('Date'[Date],-12,MONTH))))
last MTD (complete) Sales =  CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(ENDOFMONTH(dateadd('Date'[Date],-1,MONTH))))
previous month value =  CALCULATE(sum('table'[total hours value]),previousmonth('Date'[Date]))

Last year month Sales =calculate([MTD Sales],SAMEPERIODLASTYEAR('Date'[Date]))

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