In case you need this year vs Last year

On the Fly Change % = 
Var _last_year= year(max('Date'[Date Filer]))-1
Var   _This_year=year(max('Date'[Date Filer]))

Var _last_year_val= CALCULATE(sum(Sales[Sales Amount]),YEAR(Sales[Sales Date])=_last_year)
Var   _This_year_val =CALCULATE(sum(Sales[Sales Amount]),YEAR(Sales[Sales Date])=_This_year)
return
(_This_year_val-_last_year_val)/_last_year_val*100
