ROI Calculation Logic

Assuming a 20% reduction in tuning device adjustment time during assembly for string instrument manufacturers. With an annual production of 10,000 units and an adjustment labor cost of ~$35/unit (AI est.), this could lead to ~$70K/year in cost savings (AI est.). Additionally, assuming a 1% sales price increase due to improved tuning stability, for an instrument priced at ~$3,350 (AI est.), an annual revenue increase of ~$335K (AI est.) is expected. This totals an estimated annual economic impact of ~$400K (AI est.).
