Try changing one number and watch what happens to Gross revenue churn.
CollegeExplain it at college levelState the model precisely
This tool models one operating decision from explicitly supplied company assumptions. The implemented relation is Gross revenue churn = lost recurring revenue ÷ starting recurring revenue × 100, evaluated from Starting recurring revenue, Revenue lost to produce Gross revenue churn.
