ROI Calculation Logic

Assuming a reduction in static-induced product defect rate from 1.5% to 0.5% on a manufacturing line. With a monthly production of 100,000 units and a product unit price of $6.50 (AI est.), the annual economic impact from defect reduction is estimated at ~$800K (AI est.) (100,000 units/month × 12 months × (1.5% - 0.5%) × $6.50/unit = ~$800K). Additionally, a 20% reduction in inspection time from eliminating contact-based methods contributes to productivity gains.
