Please attach a workbook and expected results to help you faster.
Since you did not attach a workbook, I use superstore sample instead.
Make calculated fields:
SUM(IF YEAR([Order Date])=2017 THEN [Sales] END)
SUM(IF YEAR([Order Date])=2016 THEN [Sales] END)
([2017 Sales]-[2016 Sales])/[2016 Sales]
Put them in the view.
Hope it helps.
