ROI Calculation Logic

Assuming an average biological sample discard rate of 3% due to contamination/degradation with conventional methods, this technology could reduce the discard rate to 0.5%. For an annual throughput of 1 million samples (at $0.13/sample (AI est.)), the annual quality loss reduction is (3% - 0.5%) × 1,000,000 samples × $0.13/sample = ~$3.5K (AI est.). Additionally, a ~20% reduction in annual personnel costs for contamination inspection and reprocessing (approx. $40K/staff (AI est.)) could save ~$8K (AI est.). Total direct economic effect is ~$11.5K (AI est.). Considering accelerated R&D and enhanced product value from improved quality, potential economic effects could exceed ~$0.3M annually (AI est.).
