ROI Calculation Logic

Assuming a company manufactures pharmaceutical patches using this technology, a simplified manufacturing process could reduce the defect rate from an estimated 5% to 1%. For annual production of 1 million units, this could save ~$250K (AI est.) in reproduction costs for 40,000 units (at ~$6.50/unit, AI est.) and ~$100K (AI est.) in labor costs (equivalent to a 20% reduction in annual person-hours), totaling an estimated ~$350K/year (AI est.) in cost savings. This estimate is based on specific production volumes and defect rate improvements.
