ROI Calculation Logic

Implementing this technology could reduce annual labor and reagent costs in manufacturing quality inspection. For example, assuming 3 inspectors per line working 2,000 hours annually, with labor costs of ~$40K/person (AI est.) and annual reagent costs of ~$50K (AI est.). A 30% reduction in inspection time and a 10% reduction in reagent usage could result in annual labor cost savings of (3 people × ~$40K/person × 30%) = ~$36K (AI est.), and reagent cost savings of (~$50K × 10%) = ~$5K (AI est.). Total annual savings are estimated at ~$41K (AI est.) per line. This impact could significantly expand with multiple lines or high-frequency inspection requirements.
