ROI Calculation Logic

When applied to a manufacturing line, this technology could detect subtle defects that are difficult to identify with conventional visual inspection or basic sensors. This could reduce costs associated with customer complaints, recalls, and rework due to defective products. For example, for a product with a monthly production of 100,000 units, improving the defect rate from 1% to 0.5% (a 0.5% reduction) with a unit price of $4.00 (AI est.), the estimated annual savings would be (100,000 units × 0.005 × $4.00) × 12 months = $240,000 (AI est.).
