Drag the table calculation onto the Measures pane so you can save it as a new field (I titled it Invoice Price Pareto). With this new a Measure, you can use it in a calculated field:
WINDOW_SUM(IF [Invoice Price Paretto]<.8 THEN COUNTD([Global DUNS]) END)
WINDOW_SUM(IF [Invoice Price Pareto]>=.8 THEN COUNTD([Global DUNS]) END)
You can remove the IF statement if you want the total. So here they are all in the title:
Hope this makes sense!
