ROI Calculation Logic

Assuming this technology extends RF scattering sheet durability, reducing replacement frequency to 1/3 of conventional methods. If typical annual replacement and installation costs for conventional sheets are ~$40K (AI est.), implementing the protected sheet could save ~$25K/year (AI est.) in replacement and installation costs. Additionally, improved aesthetics could expand installation locations, leading to an estimated ~$105K/year (AI est.) in new revenue opportunities. This totals an estimated ~$130K/year (AI est.) in economic impact.
