Dax Function to Calculate Variance
Hi Experts,
I have a table in which a created a measure to calculate Margin for each department.
When i pull in this measure into a matrix table with Month in Rows and Years in column and Margin in values i get the table attached. I will like to add a column that compares 2020 and 2021 margin. Any idea how i can achieve this?

HI Nanakwame ,
You can use VAR.P dax function to calulate variance between 2 columns.
See the reference here:

Hi Pragati11
Will this work if i technically do not have 2 columns in the data? I actually just have 1 which is "margin" however when i create a matrix table and i use "Year" column which breaks the margin down by year, i will like a function that will automatically take the breakdown into effect and compare the margins.
Hi Nanakwame ,
There are few existing threads on the forum for this on how to calculate variance for different years:

If these don't help, then try sharing some sample data along with the expected result for me to try at my end.
