ROI Calculation Logic

Assuming 50 workers engaged in magnetic dust operations 20 days/year, conventional disposable mask costs are $200/person/year (100 masks x $2/mask (AI est.)). This technology, with reusable masks and replaceable magnets, reduces costs to $35/person/year (AI est.). Annual consumable savings: ($200 - $35) x 50 = $8,250 (AI est.). Additionally, reducing health risks (medical costs, sick leave, productivity loss) estimated at $1,350/person/year (AI est.) for 50 workers yields $67,500 (AI est.). Total annual cost reduction is approximately $75,750 (AI est.).
