Subtracting columns that have values shown as % of column totals

Hi,

I’ve created calculated columns to show market share for the current year and the prior year as a percent of the column total.  I’d like to show the difference between these two columns but am not getting what I want.  For instance, if the cy ms is 42.27% and the py ms was 44.06% I’d like the difference to be 1.79% instead I’m getting the difference of .29%. 

 

Here is my dax:

CY = divide(Query1[sales19],

    calculate(sum(Query1[sales19]),ALLSELECTED()),0)

 

PY = divide(Query1[sales18],

    calculate(sum(Query1[sales18]),ALLSELECTED()),0)

 

CHANGE = Query1[CY]-Query1[PY]

Re: Subtracting columns that have values shown as % of column totals

Hi @omitche2 

In your case, are these columns or measures?

Query1[sales19], Query1[sales18],

Could you show me your table struture so to provide a more clear solution?

 

Regarding comparation between the current year and the prior year, you could use DAX function as suggested below:

If you don't have date column in your table, only have "year", "month" columns, you could refer to the following thread:
