Calculating percentage for each row in a table

[Anonymous]

Hi everyone,

I'm trying to figure out how to calculate the percentage (=((Sum([CY 2017]) - Sum([Prev.CY 2017])) / Sum([Prev.CY 2017]))) for each row in the table accuractely. Here's a picture for reference.

As you can see, the numbers aren't accurate. Please help.
