ROI Calculation Logic

If an adopting company reduces the coating defect rate of expensive vacuum components from 5% to 2%, for a case manufacturing 5,000 units per year at $6,500/unit (AI est.), the estimated annual defect cost reduction is (5% - 2%) × 5,000 units × $6,500/unit = ~$1M/year (AI est.). Furthermore, extending product lifespan by 1.5 times could reduce replacement frequency, component purchase costs, and lost opportunities from downtime.
