Calculating values in preview year

Hello Dears


My question can be very simple but very common and I'm sure someone had same problem.

I have a table with following fields


2-year (text field) 4 positions Ex: 2016



I need to get the value of sales from 2015 and compare with 2014 (preview year) in a new column.

Example, for USA 2015 the year value is 25851 but I need compare it with 2014... 20394....

In the final, I need to express the difference in percentage in 2015... Diff = (25851-20394) / 20394 = 27% of increase.


Please, some guru to help me. Thanks
