Help :(Need to do YOY calculation, however do I need a date table to do this, is there a workaround?

I am very very new to PowerBI and I'm still getting my head around it, please pardon my ignorance

I have a data set

    Shoe Type | FY13 FY14 FY15 FY16 | Total 

      Heels         20     30     10     50      110

      Flats            5      10     20     15       50

      Trainers      50     50     70    100    270

I would like to show YOY percentage growth i.e. growth from FY15 to FY16 FOR "Heels" or from FY14 TO FY15 for "trainers". My companies financial year runs from June to June. Is there a way to have the YOY calculation, so that it updates with slicer selection, however without using a calendar table? I have been trying without success to create a calendar table and I was wondering if there is a simpler way to do this and have this automatically update for selections without creating a measure for each shoe type and for each FY year. 

Thanks in advance
