ROI Calculation Logic

Addressing nozzle clogging in conventional micro-nozzle devices is estimated to incur ~$50K/year (AI est.) in personnel costs and ~$65K/year (AI est.) in consumables and parts replacement. Furthermore, a 2% operational downtime on a production line generating ~$6.5M/year (AI est.) in annual revenue could result in ~$130K/year (AI est.) in opportunity loss. By introducing this technology, assuming a total of ~$245K/year (AI est.) in these combined costs and losses, a reduction of approximately 70% could yield an estimated economic benefit of ~$170K/year (AI est.).
