ROI Calculation Logic

Assuming a 1% reduction in annual user churn due to data loss in digital broadcast services, a service with 1 million monthly subscribers could prevent 10,000 user defections annually. With an average customer value of $10/month (AI est.), this could result in an annual revenue retention effect of $1.2M (AI est.). Factoring in reduced operational costs from fewer support center inquiries, an estimated annual opportunity cost reduction of ~$1M (AI est.) is projected.
