How to Manipulate Data Already Loaded to Create Calculated Data from Original Data

I am trying to manipulate data that had been already loaded into Power BI to create new calculated data  to be referenced to build a visual in my report. I also want my loaded data to automatically adjust based on the current date.

For context, I have a list of exceptions that I had filtered out by Status (Active and Expired). I want to create a seperate table from this filtered data that seperates the filtered data into three categories from original two (Active, Expiring (<30 Days from Expiring), and Expired).

These will be calculated using the equivalent of using the SumIf function in excel based on a changing current date.

Here is what I'm trying to accomplish based on an example in excel.
