Calculating percentage vertically

[Mae_Infante]

Hello Everyone,

I have a table that is linked from another table that gives me a summary by percentage for every group. Now I need to take that percentage by month vertically.

I wanted to create something like this, see screenshot below for reference.

Is this possible in airtable?
Thank you so much for future response!

Hi there,
I don’t think you’ve given us enough information to answer the question.
How are the two rollup fields being calculated? What are they rolling up? Is there a date or month field associated with the underlying data somewhere?
