Its input values are Active subscribers, Monthly subscriber churn (%), Monthly net ARPU, Churned subscribers replaced within month (%), Acquisition cost per replacement, and the main result is Annualized unreplaced churn revenue loss. Try changing one number and watch what happens to Annualized unreplaced churn revenue loss.
CollegeExplain it at college levelState the model precisely
This tool models one operating decision from explicitly supplied company assumptions. The implemented relation is Annualized churn loss = monthly churned subscribers × net ARPU × 12, evaluated from Active subscribers, Monthly subscriber churn (%), Monthly net ARPU, Churned subscribers replaced within month (%), Acquisition cost per replacement to produce Annualized unreplaced churn revenue loss. Voluntary, involuntary and migration churn should be separated and cohort retention should be measured directly. The model omits unentered taxes, cash timing, legal constraints and market uncertainty. Compare the output with company records and a downside scenario before committing resources.
The decision this tool supports
