Basic P&L by month with NOI% (How to build and display a measure in a row with dates as columns)

[SkiingAWFS]

I am new to PowerBI.  I am trying to build my first Report in PowerBI.  I have the report working in Excel but cannot see how to do similar build with Dax.  The portion of the current Excel report looks like this:

The first few lines are Pivot Table. The NOI% is simply taking the NOI for a month and dividing by the Revenue for that month.

The base data has been transformed in Power Query. It is a General Ledger report of all transactions that has been grouped at Company, Business Unit, Account Number, and MonthYear summing the amount. Each account number is allocated to a Revenue, Expense or Other category. That output is then used for the report. The pivot is simply grabbing the Revenue or Expense by month and putting out the report.  Here is a piece of the summary data after Power Query:

The differences of Excel to PowerBI are that the current report uses Pivot Tables whereas Matrix reports are different and then that the NOI% is just a basic Excel formula that has been placed right under the Pivot table.  I am trying to figure out the Dax formulas that can be displayed by month and company.  (I have a slicer that allows the company to be chosen).  Later on in the report I get to do similar reports of cost by resident and and expense by employee (all pulling in data from the HRIS and the front end database).
